Part Number: OPA27GP
Function: Ultra-Low-Noise Precision Operational Amplifier
Package: DIP 8 Pin Type
Manufacturer: Burr-Brown, Texas Instruments
The OPA27, OPA27GP 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.
