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

For battery-powered, portable applications where power is of key importance, the lowpower consumption, wide bandwidth, and ultra-low distortion performance of the OPA2834 offersperformance versus power that is not attainable in other devices.
