SGM8556
Single-Supply, Single Rail-to-Rail I/O Precision Operational Amplifier
Single-Supply, Single Rail-to-Rail I/O Precision Operational Amplifier
GENERAL DESCRIPTION

The single SGM8555 and dual SGM8556 are precision operational amplifiers which can operate from 2.5V to 5.5V single supply. These devices provide rail-to-rail input and output operation.

The SGM8555/6 offer a low offset voltage less than 90μV and an ultra-low bias current of 30pA. The combination of characteristics makes the SGM8555/6 good choices for temperature measurements, pressure and position sensors, strain gauge amplifiers and medical instrumentation, or any other 2.5V to 5.5V applications requiring precision and long-term stability.

The SGM8555 is available in Green SOT-23-5, SOIC-8 and MSOP-8 packages. The SGM8556 is available in Green SOIC-8 and MSOP-8 packages. They are specified over the extended industrial temperature range (-40 to +125).
