Product Overview
The OPA2835 is a Texas Instruments dual voltage-feedback operational amplifier in the Signal_Chain category. It provides two amplifier channels in the OPAx835 family architecture, with negative-rail input capability and rail-to-rail output operation for single-supply analog signal paths.
Supply operation is specified from 2.5 V to 5.5 V on a single supply, or +/-1.25 V to +/-2.75 V on dual supplies. The device has 250 uA/ch typical quiescent current, 0.5 uA typical power-down current, and less than 1.5 uA current in power-savings mode.
Dynamic performance includes 56 MHz bandwidth at AV = 1 V/V, 160 V/us slew rate, 10 ns rise time for a 2 VSTEP, and 55 ns settling time to 0.1% for a 2 VSTEP. Noise and distortion data include 9.3 nV/sqrt(Hz) input voltage noise at 100 kHz, 0.00015% signal-to-noise ratio at 1 kHz and 1 VRMS, and 0.00003% total harmonic distortion at the same condition.
Package information for OPA2835 lists VSSOP (10), UQFN (10), QFN (10), and an SOIC (8) package shown. The operating temperature range is -40°C to +125°C.
