3 Description

The OPA325, OPA2325, and OPA4325 (OPAx325) are precision low-voltage complementary metal-oxide-semiconductor (CMOS) operational amplifiers optimized for very low noise and high bandwidth with a quiescent operating current of only 650μA.

The OPAx325 has a linear input stage with zero-crossover distortion, capable of delivering an excellent Common Mode Rejection Ratio (CMRR) of 114dB (typ) over the entire input range. The common-mode input range extends the positive and negative supply voltages by 100mV each. The output voltage swing is typically within 10mV of the rails.

The OPAx325 combines zero-crossover distortion, high bandwidth (10MHz), high slew rate (5V/μs), and low noise (9nV/√Hz), making it an excellent successive approximation register (SAR) analog-to-digital conversion ADC (ADC) input driver amplifier. In addition, the OPAx325 has a wide supply voltage range of 2.2V to 5.5V and excellent power supply rejection ratio (PSRR) over the entire supply voltage range, making the device ideal for unregulated, direct battery powered high precision , Low-power applications.

The OPA325 (single-channel version) is available in a SOT23-5 package. The OPA2325 (dual version) is available in SO-8 and MSOP-8 packages. The OPA4325 (quad version) is available in a TSSOP-14 package.
