概要

The OPA836 and OPA2836 devices (OPAx836) are single- and dual-channel, ultra-low power, rail-to-rail output, negative-rail input, voltage-feedback (VFB) operational amplifiers designed to operate over a power-supply range of 2.5 V to 5.5 V with a single supply, or ±1.25 V to ±2.75 V with a dual supply. Consuming only 1 mA per channel and a unity-gain bandwidth of 205 MHz, these amplifiers set an industry-leading power-to-performance ratio for rail-to-rail amplifiers.

For battery-powered, portable applications where power is of key importance, the low-power consumption and high-frequency performance of the OPA836 and OPA2836 devices offer performance-versus-power capability that is not attainable in other devices. Coupled with a power-savings mode to reduce current to < 1.5 µA, these devices offer an attractive solution for high-frequency amplifiers in battery-powered applications.

The OPA836 RUN package option includes integrated gain-setting resistors for the smallest possible footprint on a printed-circuit board (approximately 2.00 mm × 2.00 mm). By adding circuit traces on the PCB, gains of +1, –1, –1.33, +2, +2.33, –3, +4, –4, +5, –5.33, +6.33, –7, +8 and inverting attenuations of –0.1429, –0.1875, –0.25, –0.33, –0.75 can be achieved. See and for details.

The OPA836 and OPA2836 devices are characterized for operation over the extended industrial temperature range of –40°C to +125°C.
