Performance




   Output Current (Iout)
 
     Output current (Iout) is the maximum continuous current that can be delivered in the output of the amplifier.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Supply Voltage (VS)
 
     Supply voltage (VS) refers to the source voltage range.
 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Quiescent Current (IQ)
 
     Quiescent current (IQ) is the current flowing through the amplifier when there is no load connected.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Input Offset Voltage (VOS)
 
     Input offset voltage (VOS) is the differential DC voltage required at the op-amp's two inputs in order force the output voltage to zero. This occurs when no load is connected to the amplifier.
 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Switching Frequency
 
     Switching frequency is the maximum switching frequency that can be sustained without exceeding the specifications. A high switching frequency (PWM) allows smaller output filters to be built into the amplifier enclosure. This design saves power, heat, and space.
 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Operating Temperature
 
     Operating temperature is specified by level (minTypMax) of the ambient temperature (in °C) in which the amplifier was designed to operate
 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
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.
