OP07Precision bipolar operational amplifier
Small input errors matter. Build a clearer precision signal path.
OP07 is a precision operational-amplifier family using a low-noise bipolar input stage and internal compensation. Negative feedback produces a controlled analog gain while low offset and drift help preserve small DC signals. It is a precision amplifier rather than a rail-to-rail or high-speed device. This page selects TI OP07CP in PDIP-8 and OP07CDR in SOIC-8, both commercial C-grade parts. Offset trim uses pins 1 and 8; pin 5 is unconnected. Package views and footprints preserve this mapping, which differs from the familiar LM741 trim arrangement. The example uses ±15 V rails, 90 kΩ feedback and 10 kΩ to the 0 V midpoint. A 0.20 V input gives an ideal 2.00 V output. The reference tables distinguish typical values from guaranteed limits; precision also depends on resistor accuracy, leakage, thermal gradients and the measurement setup.
