OP492

Data Sheet FEATURES Single-supply operation: 4.5 V to 33 V Input common-mode includes ground Output swings to ground High slew rate: 3 V/μs High gain bandwidth: 4 MHz Low input offset voltage High open-loop gain No phase inversion APPLICATIONS Disk drives Mobile phones Servo controls Modems and fax machines Pagers Power supply monitors and controls Battery-operated instrumentation GENERAL DESCRIPTION The OP292/OP492 are low cost, general-purpose dual and quad operational amplifiers designed for single-supply applications and are ideal for 5 V systems. Fabricated on Analog Devices, Inc., CBCMOS process, the OP292/OP492 series has a PNP input stage that allows the input voltage range to include ground. A BiCMOS output stage enables the output to swing to ground while sinking current.
