High-Output-Current Operational Amplifier

The OP-50 eliminates the need for an output buffer in applications which require high load-driving capability coupled with premium amplifier performance. The output stage can drive ±50mA into 50W loads. In addition, the output is stable with capacitive loads of up to 10nF. This load driving ability makes the OP-50 ideal for amplifying small signals for transmission through long cables. The amplifier features open-loop voltage gain of over 10 million with common-mode rejection and power supply rejection of greater than 126dB (A/E greades).
