Dual operational amplifier
Product specification
µA747C
DESCRIPTION
The 747 is a pair of high-performance monolithic operational
amplifiers constructed on a single silicon chip. High common-mode
voltage range and absence of “latch-up” make the 747 ideal for use
as a voltage-follower. The high gain and wide range of operating
voltage provides superior performance in integrator, summing
amplifier, and general feedback applications. The 747 is short-circuit
protected and requires no external components for frequency
compensation. The internal 6dB/octave roll-off insures stability in
closed-loop applications. For single amplifier performance, see
µA741 data sheet.
FEATURES
• No frequency compensation required
• Short-circuit protection
• Offset voltage null capability
• Large common-mode and differential voltage ranges
• Low power consumption
• No latch-up
