OPA376AQDBVRQ1 Desciprion

The OPA376AQDBVRQ1 is part of a new family of low-noise e-trim operational amplifiers that provide exceptional dc precision and ac performance. This device's rail-to-rail output, low offset (maximum of 25 V), low noise (maximum of 7.5 nV/Hz), the quiescent current of 950 A (maximum), and 5.5-MHz bandwidth make it ideal for a variety of precision and portable applications. Furthermore, the OPA376AQDBVRQ1 has a wide supply range and a high PSRR, making it a good choice for applications that run straight from batteries without regulation.
