The OPA835IDBVT is an ultra-low power voltage-feedback Operational Amplifier with rail to rail output and negative rail input. Consuming only 250μA per channel and an unity gain bandwidth of 56MHz, this amplifier set an industry-leading performance-to-power ratio for rail-to-rail amplifier. For battery-powered portable applications where power is of key importance, the low power consumption and high-frequency performance of the OPA835 device offers performance versus power that is not attainable in other devices. Coupled with a power-savings mode to reduce current to <1.5μA, the device offers an attractive solution for high-frequency amplifiers in battery-powered applications.
