DESCRIPTION
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 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 chan-
nel 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.
