Overview
The Texas Instruments OPA836IDBVR is a single-channel, ultra-low power, rail-to-rail output, and negative rail input voltage-feedback (VFB) operational amplifier. This device is designed to operate over a wide power-supply range of 2.5 V to 5.5 V with a single supply, or ±1.25 V to ±2.75 V with a dual supply. It is particularly suited for battery-powered, portable applications where low power consumption and high-frequency performance are critical.
