OPA347 (ACTIVE)

Micropower Rail-To-Rail Operational Amplifier

 

Description

The OPA347 is a microPower, low-cost operational amplifier available in micropackages. The OPA347 (single version) is available in the SC-70 and SOT23-5 packages. The OPA2347 (dual version) is available in the SOT23-8 and WCSP-8 packages. Both are also available in the SO-8. The OPA347 is also available in the DIP-8. The OPA4347 (quad) is available in the SO-14 and the TSSOP-14.

The small size and low power consumption (34µA per channel maximum) of the OPA347 make it ideal for portable and battery-powered applications. The input range of the OPA347 extends 200mV beyond the rails, and the output range is within 5mV of the rails. The OPA347 also features an excellent speed/power ratio with a bandwidth of 350kHz.

The OPA347 can be operated with a single or dual power supply from 2.3V to 5.5V. All models are specified for operation from –55°C to +125°C.
