OPA2325IDR-Precision, 10-MHz, Low-Noise, Low-Power, RRIO, CMOS Zero-Crossover Operational Amplifier

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

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

The zero-crossover distortion combined with wide bandwidth (10 MHz), high slew rate (5 V/µs), and low noise (9 nV/√Hz) make the OPA2325 a very good successive-approximation register (SAR) analog-to-digital converter (ADC) input driver amplifier. The low offset, and 0.2-pA input bias current make this device ideal for a wide range of precision applications with high-impedance sensors. The unique feature of interfacing to high-impedance sensors on the input and being able to drive ADC inputs with very little distortion make the OPA2325 suitable for various data acquisition and process control applications.

In addition, the OPA2325 has a wide supply voltage range from 2.2 V to 5.5 V with excellent power-supply rejection ratio (PSRR) over the entire supply range, making the device suitable for precision, low-power applications that run directly from batteries without regulation.
