LT1492 Description

The LT1492 are quad, low power, single supply precision op amps with 5MHz gain-bandwidth product, 3V/µs slew rate and only 450µA of quiescent supply current per amplifier.

With a maximum input offset voltage of only 180µV, the LT1492 eliminate trims in most systems while providing high frequency performance not usually found in low power single supply amplifiers.

The LT1492 will operate on any supply greater than 2.5V and less than 36V total, and are specified on single 3.3V, single 5V and ±15V supplies. Even with their low quiescent supply current the minimum output drive is 20mA, ideal for driving low impedance loads.

The inputs can be driven beyond the supplies without damage or phase reversal of the output. The low operating voltage and wide input and output range make the LT1492 amplifiers ideal for battery-powered applications.
