Part Number : OPA27GP
Function : Ultra-Low-Noise Precision Operational Amplifier
Manufacturers : Texas Instruments
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.
