Description

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 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 unity-gain bandwidth of 50 MHz, this amplifier sets an industry-leading performance-to-power ratio for rail-to-rail amplifiers. For battery-powered and portable applications where low power consumption is of key importance, the OPA2834 offers an excellent bandwidth to IQratio. OPA2834 offers very low distortion making it very suitable for data acquisition systems and microphone pre-amplifier. See theDevice Comparison Tablefor a selection of low-power, low-noise, 5-V amplifiers from Texas Instruments with a gain-bandwidth product from 20 MHz to 300 MHz.
