DESCRIPTION
The OPA27/37 is an ultra-low noise, high precision
monolithic operational amplifier.
Laser-trimmed thin-film resistors provide excellent
long-term voltage offset stability and allow superior
voltage offset compared to common zener-zap tech-
niques.
A unique bias current cancellation circuit allows bias
and offset current specifications to be met over the full
鈥?5擄C to +125擄C temperature range.
The OPA27 is internally compensated for unity-gain
stability. The decompensated OPA37 requires a closed-
loop gain

The Burr-Brown OPA27/37 is an improved replace-
ment for the industry-standard OP-27/OP-37.
