Device Type




           
   Your choices are...
 
      
 
   Audio Amplifiers
 
     Audio amplifiers are units that amplify a sound signal, which is then sent to a speaker or another amplifier. Audio amplifiers are used to strengthen an audio signal and make it available for more powerful amplification. 
 
   Buffer
 
     A buffer amplifier is an amplifier with unity gain.
 
   Comparators
 
     Analog comparators are amplifiers that compare the magnitude of voltages at two inputs. An analog comparator is an operational amplifier that can have negative feedback removed, with no feedback, and very high gain. The output voltage goes to one extreme to the other.
 
   Current Sense Amplifier
 
     Current sense amplifiers are integrated circuits with operational amplifiers and sense resistors that are used in measuring the amplitude and direction of current in circuits.
 
   Differential Amplifiers
 
     Differential amplifier chips are designed to amplify the difference between two input signals. They can amplify a small difference between two signal levels and ignore any common level shared between them.
 
   Instrumentation Amplifiers
 
     Instrumentation amplifier chips are precision amplifier circuits with both high-impedance differential inputs and high common-mode rejection (CMRR). These amplifiers are a type of operational amplifiers that are used for very accurate and low-noise measurements due to their high input impedance and high common-mode rejection. The differential gain of an instrumentation amplifier chip can be adjusted by changing the value of a single resistor.
 
   Isolation Amplifiers
 
     Isolation amplifiers electrically isolate input and output signals, often by inductive couplings. Isolation amplifiers or iso-amps may be used to protect components from potentially dangerous voltages or to amplify low-level analog signals in applications with multiple channels.
 
   Log Amplifiers
 
     Logarithmic amplifier chips produce an output voltage that is directly proportional to the logarithm of the input voltage. Logarithmic amplifiers or log amplifiers are mainly used in applications that require the compression of signals, such as video and audio equipment.
 
   Operational Amplifiers
 
     Operational amplifier chips are general-purpose, closed loop devices used to implement linear functions. Operational amplifier chips are widely used in signal processing circuits, control circuits, and instrumentation.
 
   Power Operational Amplifiers
 
     Power operational amplifiers (POA) are used to increase the power of low-level signals in applications that drive low impedances or reactive loads. They dissipate excess energy as heat, deliver extensive current, and can sustain relatively high supply voltages.
 
   Variable Gain Amplifiers
 
     Variable gain amplifiers are amplifiers whose gain can be changed by the user.
 
   PWM Amplifiers
 
     Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. PWM amplifiers have a much higher power capability for a given voltage than linear amplifiers.
 
   Sample and Hold Amplifiers
 
     Sample-and-hold amplifiers are operational amplifiers whose input may be turned to sample a voltage. When turned off they can hold the sampled voltage at the output, while an ADC converts the voltage to a digital number.
 
   Video / Wideband Amplifiers
 
     Video or wideband amplifiers are used in video circuits for the processing of video signals.
 
   Other
 
     Other unlisted or proprietary amplifiers.

Package Characteristics




   Package Type       
   Your choices are...
 
      
 
   DIP
 
     Dual in-line package (DIP) is a type of semiconductor component packaging. DIPs can be installed either in sockets or permanently soldered into holes extending into the surface of the printed circuit board. The pins are distributed into two parallel lines along opposite site of the rectangular package. There are several types of DIP packages, such as Ceramic Dual in-line package (CDIP), Plastic Dual in-line package (PDIP), and Shrink Plastic Dual in-line package (SPDIP).
 
   CDIP
 
     Ceramic dual in-line package (CDIP) consists of two pieces of dry pressed ceramic surrounding a "DIP formed" lead frame. The ceramic / LF / ceramic system is held together hermetically by frit glass reflowed at temperatures between 400° - 460° centigrade.
 
   PDIP
 
     Plastic dual in-line package (PDIP) is widely used for low cost, hand-insertion applications including consumer products, automotive devices, logic, memory ICs, micro-controllers, logic and power ICs, video controllers commercial electronics, and telecommunications.
 
   DPAK
 
     DPAK refers to a type of transistor outline package (T0-252).
 
   CSP
 
     Chip scale package or chip size package (CSP) has an area that is no more than 20% larger than the built-in die. CSP is compact for second level packaging efficiency and encapsulated for second level reliability. CSP is superior to both direct-chip-attach (DCA) and chip-on-board (COB) technologies. CSP is used in a variety of integrated circuits (IC), including radio frequency ICs (RFIC), memory ICs, and communication ICs.  
 
   SIP
 
     SIP refers to a single inline package.
 
   SOIC
 
     SOIC refers to a small outline IC.
 
   SSOP
 
     SSOP refers to a shrink small outline package.
 
   SOP
 
     SOP is a small outline package.
 
   MSOP
 
     Mini small outline plastic package (MSOP) products are packed in tape reel assemblies that include a carrier tape with embossed cavities for storing individual components. The carrier tape is made from dissipative polystyrene resin. The cover tape is a multilayer film composed of a polyester film, adhesive layer, heat-activated sealant, and anti-static sprayed agent. The reel is made of polystyrene plastic (anti-static coated or intrinsic) and individually bar-coded. Reels are placed inside barcode-labeled boxes for shipping.
 
   SOT
 
     SOT packaging refers to a small outline transistor.
 
   SOT23
 
     SOT23 is a rectangular, surface mounted, small outline transistor (SOT) package with three or more gull wing leads. SOT23 features a very small footprint and is optimized for the highest possible current. Because of its low cost and low profile, SOT23 is used in home appliances, office and industrial equipment, personal computers, printers, and communication equipment.
