DESCRIPTION

The OPA27 and OPA37 are ultra-low noise, high-precision

monolithic operational amplifiers.

Laser-trimmed thin-film resistors provide excellent long-term

voltage offset stability and allow superior voltage offset

compared to common zener-zap techniques.

A unique bias current cancellation circuit allows bias and

offset current specifications to be met over the full –40°C to

+85°C temperature range.

The OPA27 is internally compensated for unity-gain stability.

The decompensated OPA37 requires a closed-loop gain ≥ 5.

The Texas Instruments’ OPA27 and OPA37 are improved

replacements for the industry-standard OP-27 and OP-37.
