The Texas Instruments OPA2356AIDR is a dual CMOS operational amplifier with rail-to-rail output, packing 450 MHz of -3 dB bandwidth and a 360 V/µs slew rate into a standard 8-SOIC footprint. It operates from a single 2.5 V to 5.5 V supply and draws 8.3 mA per channel quiescent. The input bias current sits at 3 pA, and each channel can source or sink 100 mA. The -40°C to 125°C temperature range makes it a candidate for industrial signal conditioning, video buffering, and high-speed ADC driver stages where board space is tight and two channels are needed.
360 V/µs slew rate — what it means for the signal chain
The 360 V/µs slew rate is the headline dynamic spec. It defines how fast the output can swing under a large-signal step — relevant for video line drivers, pulse amplifiers, and any application where the output must track a fast input without slew-induced distortion. Paired with the 450 MHz -3 dB bandwidth, this part handles multi-MHz signals cleanly. The 2 mV input offset and 3 pA bias are typical for CMOS inputs; the rail-to-rail output stage keeps headroom in low-voltage single-supply rails.
Package and mounting
The OPA2356AIDR comes in an 8-SOIC package (3.90 mm body width) for surface-mount assembly. The supplier device package is also 8-SOIC. It is supplied in Tape & Reel (TR) or Cut Tape (CT) options. The dual-channel layout in a single SOIC-8 saves board area compared to two single op-amps, and the CMOS input stage eliminates the need for a negative supply in many single-supply designs.
