Introduction

AI Translation

The COSINA333-20 and COSINA333-50 are gain selectable, zero-drift instrumentation amplifiers operated on 1.8 to 5.5 supplies. They don’t need external precision resistors to set the gain. The gain options can be selected by toggling the gain select (GS) pin. They also have an integrated shutdown option to turn off the amplifiers when idle for additional power savings in battery powered applications. The COSINA333 family uses auto-calibration technique to provide very low offset voltage (less than 125μV maximum) and near zero drift over temperature. Low quiescent supply current of 70μA and very low input bias current make the device an ideal choice for low offset, low power consumption and high impedance applications.
