microPower, Rail-to-Rail  
Operational Amplifiers  
FEATURES  
LOW IQ: 20µA  
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.  
microSIZE PACKAGES: WCSP-8, SC70-5  
SOT23-5, SOT23-8, and TSSOP-14  
HIGH SPEED/POWER RATIO WITH  
BANDWIDTH: 350kHz  
RAIL-TO-RAIL INPUT AND OUTPUT  
SINGLE SUPPLY: 2.3V to 5.5V  
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.  
APPLICATIONS  
PORTABLE EQUIPMENT  
BATTERY-POWERED EQUIPMENT  
2-WIRE TRANSMITTERS  
SMOKE DETECTORS  
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.
