AX358P / AX358S
Low Power Dual Operational Amplifiers
Description
These devices consist of two independent, high gain, internally frequencycompensated operational amplifiers designed operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3V to 32V, and Vcc is at least 1.5V more positive than the input common-mode voltage, The low supply-current drain is independent of the magnitude of the power supply voltage.
8-Lead Plastic DIP-8 Package Code: P •
8-Lead Plastic SO-8 Package Code: S
Features
• Two internally compensated OP amps • Internally frequency compensated for unity gain • Short Circuit Protected Outputs • W ide power supply range: 3VDC to 32VDC (Single supply) • Input common-mode voltage range includes ground • Large output voltage swing: 0VDC to Vcc-1.5VDC
