OPA2834 Overview
The OPA2834 is a dual-channel, ultra-low-power, railto-rail output, negative-rail input, voltage-feedback (VFB) operational amplifier designed to operate over a power-supply range of 2.7 V to 5.4 V with a single supply, or ±1.35 V to ±2.7 V with a dual supply. Consuming only 170 µA per channel and with a unitygain bandwidth of 50 MHz, this amplifier sets an industry-leading performance-to-power ratio for railto-rail...
