Descripción

Productos

The OP07CDR from Texas Instruments is a precision operational amplifier with ultra-low 60µV max input offset voltage in an SOIC-8 package. Using a chopperless bipolar input stage, it achieves 112dB open-loop gain, 100dB min CMRR, and excellent long-term stability of 0.5µV/month — making it the industry standard for precision DC amplification.

The OP07CDR from TI is a precision op amp in SOIC-8 with 60µV max input offset voltage, 0.7µV/°C drift, and 0.5µV/month long-term stability. Chopperless bipolar input achieves 100dB min CMRR and 112dB open-loop gain without chopper switching noise. 600kHz GBW and 0.3V/µs slew rate. ±3V to ±18V supply range. C suffix denotes commercial temperature (0-70°C), D suffix denotes SOIC-8, R suffix denotes tape-and-reel. Industry-standard precision DC amplifier since 1975.

The OP07 uses a bipolar input stage with carefully matched super-beta transistors and on-chip trimming to achieve the ultra-low 60µV max offset voltage. Unlike chopper-stabilized amplifiers, it uses no switching, avoiding the associated switching noise, aliasing, and idle-tone issues. The offset null pins (pins 1 and 8) allow external trimming to zero using a 20kΩ potentiometer for applications requiring even lower offset. The true differential input with high CMRR (100dB min) makes it ideal for bridge and instrumentation amplifier configurations. The internal frequency compensation capacitor provides unity-gain stability without external components.
