OPA2834 的說明
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 IQ ratio. OPA2834 offers very low distortion making it very suitable for data acquisition systems and microphone pre-amplifier.
