| UA776 PROGRAMMABLE LOW POWER SINGLE OPERATIONAL AMPLIFIERS . . . . . . MICROPOWER OPERATION NO FREQUENCY COMPENSATION REQUIRED WIDE PROGRAMMING RANGE HIGH SLEW RATE SHORT-CIRCUIT PROTECTION PROGRAMMABLE SINGLE OP-AMP N DIP8 (Plastic Package) D SO8 (Plastic Micropackage) ORDER CODES Part Number UA776C UA776I UA776M Temperature Range 0 C, +70 C -40oC, +105oC -55oC, +125oC o o Package N * * * D * * * Example : UA776CN DESCRIPTION The UA776 programmable operational amplifier is characterized by low supply current and low equivalent input noise voltage over a wide range of operating supply voltages. Coupled with programmable electrical characteristics, it is a versatile amplifier for use in high accuracy, low power consumption analog applications. Input noise voltage and current, power consumption and input current can be optimized by a single resistor or current source that sets the chip quiescent current for nano-watt power consumption or for characteristics similar to the UA741. Internal frequency compensation,absence of latch up, high slew rate and short-circuit protection assure ease of use in long time integrators, active filters, and sample and hold circuits.
