The OP07CD from Texas Instruments is a low-offset voltage precision operational amplifier offering 60 uV maximum input offset voltage and 0.5 uV/C typical drift. Using a low-noise, chopperless, bipolar-input transistor amplifier circuit, it provides long-term stability without the complexity of chopper-stabilized designs. The true differential input with wide common-mode range and 110 dB CMRR ensures excellent performance in high-noise environments. No external components are required for offset nulling or frequency compensation. The device operates from ±3V to ±18V supplies with 600 kHz gain-bandwidth product.

The OP07CD uses a bipolar-input differential pair with super-beta transistors to achieve low input bias current (1.8 nA typical) while maintaining low offset voltage. Internal laser trimming sets the input offset to 60 uV maximum without external nulling. The amplifier uses a single-stage topology with internal compensation (dominant pole) for unconditional stability. Offset null pins (OFFSET N1/N2) allow further adjustment if needed. The wide input voltage range (0 to ±14V on ±15V supply) and high open-loop gain (110 dB typical) make it suitable for precision DC and low-frequency applications.
