Fabricated using the industry-leading BiCom-3x (SiGe complimentary bipolar) process, the OPA2835 is a single and dual ultra low-power, rail-to-rail output, negative rail input, voltage-feedback operational amplifier. Consuming only 250 µA per channel and a unity gain bandwidth of 56MHz, 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 OPA2835s low power consumption and high frequency performance offers designers performance versus power not attainable in other devices. Coupled with a power savings mode to reduce current to <1.5 µA, the device offers an attractive solution for high frequency amplifiers in battery powered applications.
