Overview
The TLV170IDR from Texas Instruments is a single-channel, 36-V, 1.2-MHz, low-power operational amplifier designed for cost-sensitive applications. This device is part of the TLVx170 family, which includes EMI-hardened, single-supply, low-noise operational amplifiers. The TLV170IDR is suitable for microvolt-level signal amplification due to its low noise, high power-supply rejection ratio (PSRR), and good offset, drift, and bandwidth characteristics. It operates over a wide supply voltage range from 2.7 V to 36 V and is unity-gain stable with a 200-pF capacitive load.
