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 and portable applications where low power consumption is of keyimportance, the OPA2834 offers an excellent bandwidth to IQ ratio. OPA2834offers very low distortion making it very suitable for data acquisition systems and microphonepre-amplifier.
