OPA2277U

OPA2277U Description

The OPA2277U from Texas Instruments is a high-precision, general-purpose operational amplifier (op-amp) designed for demanding analog applications. Housed in an 8-SOIC package, this dual-channel IC delivers exceptional performance with a 10 µV input offset voltage, 500 pA input bias current, and a 1 MHz gain bandwidth product. Operating over a 4V to 36V supply range, it consumes 790µA per channel, making it suitable for both low-power and high-voltage systems. Its 0.8V/µs slew rate and 35 mA output current ensure robust signal integrity in dynamic environments. Compliant with ROHS3 and REACH standards, the OPA2277U is ideal for precision instrumentation, industrial control, and portable devices.
