TI OPA2836ID

The OPA836 is a single- and dual-channel ultralow-power, rail-to-rail output, negative rail input, voltage-feedback op amp designed for operation from 2.5V to 5.5V single-supply and ±1.25V to ±2.75V dual-supply ranges. With only 1mA quiescent current per channel and 205MHz gain bandwidth product, it sets an industry-leading power-performance ratio for rail-to-rail amplifiers. For battery-powered portable applications where power consumption is critical, its combination of low power and high-frequency performance offers a power-performance ratio unavailable from other devices. Combined with a power-save mode drawing less than 1.5μA, this device provides a highly attractive solution for high-frequency amplification in battery-powered applications. The device operates over the extended industrial temperature range of -40°C to 125°C.
