3 Description
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.
