Introduction

AI Translation

The OPA2834 is a dual-channel, ultra-low-power, rail-to-rail output, negative rail input, voltage feedback (VFB) op-amp designed to operate from a supply voltage range of 2.7V to 5.4V (single supply) or ±1.35V to ±2.7V (dual supply). This amplifier consumes only 170μA per channel with a unity-gain bandwidth of 50MHz, delivering an industry-leading performance-to-power ratio among rail-to-rail amplifiers. For battery-powered and portable applications requiring low power consumption, the OPA2834 offers an excellent bandwidth-to-IQ ratio. With ultra-low distortion, the OPA2834 is ideal for data acquisition systems and microphone preamplifiers.
