Texas Instruments OPA2835 Dual VFB Op Amps

Texas Instruments OPA2835 dual VFB operational amplifiers (op amps) are low-power, rail-to-rail output, negative rail input, voltage-feedback devices designed to operate over a power supply range of 2.5V to 5.5V single supply and ±1.25V to ±2.75V dual supply. These TI op amps consume only 250µA per channel with a unity gain bandwidth of 56MHz, giving them an industry-leading power-to-performance ratio for rail-to-rail amplifiers. Texas Instruments OPA2835 VFB op amps are ideal for low power signal conditioning, audio ADC input buffer, and low power SAR and delta-sigma ADC driver applications.
