Texas Instruments OPA328
The OPAx328 have a linear input stage with zerocrossover distortion that delivers excellent commonmode rejection ratio (CMRR) of 120dB (typical) over the full input range. The input common-mode voltage range extends 100mV beyond the negative and positive supply rails. The output voltage typically swings within 10mV of the rails.| Part No. | OPA328 |

DESCRIPTION
The single-channel OPA328 and dual-channel OPA2328 (OPAx328) are a new generation family of precision, low-voltage CMOS operational amplifiers optimized for very low noise and wide bandwidth. The OPAx328 also use Texas Instrument's proprietary e‑trim™ operational amplifier technology, enabling a unique combination of ultra-low offset and low input offset drift without the need for any input switching or auto-zero techniques.
