OP22S: Aerospace Programmable Micro Power Op Amp
The OP22 is a monolithic micropower operational amplifier designed to provide excellent accuracy in high-gain applications. Offsets are very low which generally eliminates any need for external nulling of VOS. The OP22 is internally compensated and unity-gain stable. It also features high open-loop gain, CMRR and PSRR. This assures gain accuracy and rejection of power supply variations even when used in circuits with high closed-loop gain. The low offsets and high gain accuracy of the OP22 bring precision performance to the micropower field.
The OP22 is a versatile op amp designed for operation from battery or solar-cell power sources. Supply current is programmable over a range of 500nA to 400uA with a single external resistor. Input voltage range is very wide and extends down to the negative rail, thus the common-mode input voltage range includes ground when operating from a single supply voltage. This ability to provide high DC performance over a wide input range is particularly useful in single-battery applications. In addition, the OP22 is characterized over a wide supply range of ±1.5± to ±15V, or +3V to +30V for single supply.
The OP22 pin-out and offset nulling are identical to the LM4250 and many other micropower operational amplifiers. This functional commonality allows easy upgrading of system performance. By selection of set resistor value, the circuit designer can readily use the OP22 in place of such amplifiers as the LM108, LM112, and LM4250 in high-gain, low-frequency applications.
