RS358
Low Power Dual Operational Amplifiers
DESCRIPTION
FEATURES
These devices consist of two independent, high gain,
internally
frequency-compensated
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.
• Two internally compensated OP amps
• Internally frequency compensated for unity gain
• Short circuit protection
• Wide power supply range: 3VDC to 32VDC (Single
supply)
• Input common-mode voltage range includes
ground
• Large output voltage swing: 0VDC to Vcc-1.5VDC
