The OP495GSZ is a rail-to-rail quad Operational Amplifier for use with actuator drives. The rail-to-rail output swing combined with DC accuracy is the key feature of the OP495 quad CBCMOS operational amplifier. By using a bipolar front end, lower noise and higher accuracy than those of CMOS designs have been achieved. The input and output ranges include the negative supply, providing the user with zero-in/zero-out capability. For users of 3.3V systems such as lithium batteries, the OP495 is specified for 3V operation. Maximum offset voltage is specified at 300μV for 5V operation and the open-loop gain is a minimum of 1000V/mV. This yields performance that can be used to implement high accuracy systems, even in single-supply designs. The ability to swing rail-to-rail and supply 15mA to the load makes the OP495 ideal drivers for power transistors and H bridges.
