Description

The OP03B cell is an internally compensated operational amplifier with a PMOS input stage. The amplifier is designed for low noise and low offset applications. 
The operational amplifier has a power-down mode to permit very low standby currents. This mode is controlled by the complementary signals "pd" and "xpd".
