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.
