OPA2347

采用 WCSP-8 封装的微功耗轨至轨运算放大器

The OPA347 is a _micro_Power, low-cost operational amplifier available in _micro_packages. The OPA347 single version is available in the SC-70 and SOT23-5 packages. The 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.
