Description

The LT®1492/LT1493 are dual/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/LT1493 eliminate trims in most systems while providing high frequency performance not usually found in low power single supply amplifiers. The LT1492/LT1493 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/LT1493 amplifiers ideal for battery-powered applications. For applications requiring faster precision single supply amplifiers, see the 14MHz, 7V/µs LT1211/LT1212, the 28MHz, 12V/µs LT1213/LT1214 or the 23MHz, 50V/µs LT1215/LT1216.
