The TLVx825 is part of a family of zero-drift operational amplifiers from TI. The zero-drift architecture provides precision performance such as lower offset, lower offset drift over temperature, greater offset stability over time and a flat noise floor. TLVx825 achieves an input referred offset voltage of 4µV, an offset drift of 0.02µV/°C over the entire operating temperature range of –40°C to +125°C, along with a low frequency noise of just 320nV_PP in the standard 0.1 – 10Hz range. In addition, this device offers excellent linear performance with high CMRR, PSRR, and A_OL. This combination of specs provide excellent accuracy in high gain applications, thereby greatly reducing the need for system level calibration.

The TLVx825 operational amplifiers combine precision offset and drift with excellent overall ac performance, making the device a great choice for a wide variety of precision voltage sensing and current sensing applications. This device operates from 1.8V to 5.5V with a quiescent current of 500µA while achieving a robust cap load drive of 300pF with a 30% overshoot in unity gain. The device also offers good ac performance of 3.5MHz bandwidth, 15nV/√Hz broad-band noise, and a good distortion performance when operating at less than the chopper frequency of 200kHz.
