OPA2244UA

OPA2244UA Description

The OPA2244UA from Texas Instruments is a high-performance, general-purpose operational amplifier designed for precision analog applications. Part of the MicroAmplifier™ series, this dual-channel op-amp operates over a wide supply voltage range (2.2V to 36V), making it versatile for both low-voltage and industrial-level designs. With a gain bandwidth product of 430 kHz and a slew rate of 0.1V/µs, it balances speed and power efficiency, drawing only 40µA per channel. Its ultra-low input bias current (10 nA) and low offset voltage (700 µV) ensure high accuracy in signal conditioning and sensor interfacing. Packaged in an 8-SOIC tube, it is RoHS3 compliant and rated for MSL 3 (168 hours) moisture sensitivity.
