OP27GP vs OPA227P vs OPA27GP Comparison

General Purpose Amplifier 1 Circuit 8-PDIP

The OPA227P is an Operational Amplifier combines low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both AC and precision DC performance. The OPAx227 is unity-gain stable and features high slew rate (2.3V/µs) and wide bandwidth (8MHz). The OPAx227 series operational amplifier is pin-for-pin replacements for the industry standard OP-27 and OP-37 with substantial improvements across the board.

The OPA27GP is an ultra-low noise precision monolithic Operational Amplifier for use with radiation hard equipment. Laser-trimmed thin-film resistors provide excellent long-term voltage offset stability and allow superior voltage offset compared to common zener-zap techniques. An unique bias current cancellation circuit allows bias and offset current specifications to be met over the full -40 to +85°C temperature range. The OPA27 is internally compensated for unity-gain stability.
