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 Table 9-1 and Table 9-2 for details.

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