General Purpose Amplifier 2 Circuit 8-MSOP
The OP2177ARZ is a very high precision Operational Amplifier featuring extremely low offset voltage and drift, low input bias current, low noise and low power consumption. Outputs are stable with capacitive loads of over 1000pF with no external compensation. Supply current is less than 500µA per amplifier at 30V. Internal 500R series resistors protect the inputs, allowing input signal levels several volts beyond either supply without phase reversal.
The OPA2335AIDGKT is a CMOS Operational Amplifier uses auto-zeroing techniques to simultaneously provide very low offset voltage (5µV maximum) and near zero drift over time and temperature. This miniature, high-precision, low quiescent current amplifier offers high input impedance and rail-to-rail output swing. This op amp is optimized for low-voltage, single-supply operation. Under logic control, the amplifier can be switched from normal operation to a standby current of 2µA. When the enable pin is connected high, the amplifier is active. Connecting enable low disables the amplifier and places the output in a high impedance state.
