LT1491ACS#TRPBF

LT1491ACS#TRPBF Description

The LT1491ACS#TRPBF from Analog Devices Inc. is a quad-channel, general-purpose operational amplifier (op-amp) designed for precision and low-power applications. Housed in a 14-pin SOIC package and supplied in Tape & Reel (TR), this IC operates over a wide supply voltage range of 2V to 44V, making it versatile for both low-voltage and high-voltage systems. With a Gain Bandwidth Product (GBWP) of 200 kHz and a slew rate of 0.06V/µs, it balances moderate speed with ultra-low power consumption, drawing just 50µA per channel. Its low input bias current (1 nA) and input offset voltage (285 µV) ensure high accuracy in signal conditioning and sensor interfacing.
