Texas Instruments  OPA2325IDR

The OPA2325 is a dual, precision, low-voltage complementary metal-oxide semiconductor(CMOS) operational amplifier optimized for very low noise and wide bandwidth while operating on alow quiescent current of only 650 µA.

The OPA2325 features a linear input stage with zero-crossover distortion that deliversexcellent common-mode rejection ratio (CMRR) of typically 114 dB over the entire input range. Theinput common-mode range extends 100 mV beyond the negative and positive supply rails. The outputvoltage typically swings within 10 mV of the rails.

The zero-crossover distortion, combined with wide bandwidth (10 MHz), high slew rate (5V/µs), and low noise (9 nV/√Hz), make the OPA2325 a very goodsuccessive-approximation register (SAR) analog-to-digital converter (ADC) input driver amplifier.In addition, the OPA2325 has a wide supply-voltage range from 2.2 V to 5.5 V with excellentpower-supply rejection ratio (PSRR) over the entire supply range, making the device suitable forprecision, low-power applications that run directly from batteries without regulation.
