OPA2735AID Description

The OPA2735AID from Texas Instruments is a high-performance, dual-channel zero-drift operational amplifier designed for precision applications. Packaged in an 8-SOIC tube, this IC operates over a 2.7V to 12V supply range, making it versatile for both low-voltage and industrial systems. With an ultra-low input offset voltage of 1 µV and minimal input bias current of 100 pA, it ensures exceptional accuracy in signal conditioning. The 1.6 MHz gain bandwidth product (GBW) and 1.5V/µs slew rate enable stable performance in dynamic environments, while its 600µA per-channel supply current optimizes power efficiency.
