The OPA2836-Q1 device is a dual-channel, ultra-low power, rail-to-rail output, negative-rail input, voltage-feedback operational amplifier designed to operate over a power-supply range of 2.5 V to 5.5 V (single supply), or ±1.25 V to ±2.75 V (dual supply). Consuming only 1 mA per channel with a unity-gain bandwidth of 205 MHz, this amplifier sets an industry-leading, power-to-performance ratio for rail-to-rail amplifiers.

For battery-powered, portable applications where power is a key importance, the low-power consumption and high-frequency performance of the OPA2836-Q1 offers designers performance-versus-power that is not attainable in other devices.

The OPA2836-Q1 is characterized for operation over the extended industrial temperature range of –40°C to +125°C.
