Dual CMOS op-amp in a through-hole DIP
The TLV2772CP is a dual-channel CMOS operational amplifier from Texas Instruments, packaged in an 8-pin DIP (0.300" width, 7.62 mm pitch) for through-hole assembly. It delivers a 5.1 MHz gain-bandwidth product and a 10.5 V/µs slew rate, making it suitable for signal conditioning in audio, sensor front-ends, and general-purpose analog processing where speed matters more than micropower draw.
Rail-to-rail output and supply flexibility
Rail-to-rail output swing means the output can reach within millivolts of both supply rails, preserving dynamic range in low-voltage systems. The supply span runs from 2.5 V to 5.5 V, so it operates on a single 3.3 V or 5 V rail without a negative supply — common in battery-powered or single-supply designs. Each channel draws 1 mA quiescent supply current, totalling 2 mA for both amplifiers. Output current capability is 50 mA per channel, enough to drive moderate loads like audio line outputs or ADC reference buffers without an external buffer stage. Input bias current is 2 pA typical, and input offset voltage is 500 µV. The low bias suits high-impedance sources like photodiode or pH probe front-ends, where bias current error would otherwise dominate the offset.
Temperature grade and deployment context
Rated for 0°C to 70°C ambient, the TLV2772CP is a commercial-temperature part. It fits indoor equipment, benchtop instruments, and controlled-environment industrial controls — not engine bays or outdoor telecom cabinets where -40°C to +125°C parts are required.
