OPA835 VFB Amplifiers

OPA835 is a single ultra-low-power, rail-to-rail output, negative rail input, voltage-feedback operational amplifier

Image of Texas Instruments' OPA835 VFB AmplifierFabricated using the industry-leading BiCom-3x (SiGe complimentary bipolar) process, Texas Instruments' OPA835 is a single ultra-low-power, rail-to-rail output, negative rail input, voltage-feedback operational amplifier designed to operate over a power supply range of 2.5 V to 5.5 V single supply and ±1.25 V to ±2.75 V dual supply. Consuming only 250 µA per channel and a unity gain bandwidth of 56 MHz, these amplifiers set an industry leading power-to-performance ratio for rail-to-rail amplifiers.
