OPA4704 OPERATIONAL AMPLIFIER IC Chip

OPA4704（CMOS,Rail-to-Rail, I/O,OPERATIONAL AMPLIFIER）

Introduction

The OPA703-OPA2703,OPA4703 and OPA704-OPA2704,OPA4704 series op amps are optimized for applications requiring rail-to-rail input and output swing.Single, dual, and quad versions are offered in a variety of packages. While the quiescent current is less than 200μA per amplifier, the OPA703 still offers excellent dynamic performance (1MHz GBW and 0.6V/us SR) and unity-gain stability. The OPA704 is optimized for gains of 5 or greater and provides 3MHz GBW and 3V/µs slew rate.

The OPA703-OPA2703,OPA4703 and OPA704-OPA2704,OPA4704 series are fully specified and guaranteed over the supply range of ±2V to ±6V. Input swing extends 300mV beyond the rail and the output swings to within 40mV of the rail.

The single versions (OPA703 and OPA704) are available in the MicroSIZE SOT23-5 and in the standard SO-8 surface-mount, as well as the DIP-8 packages. Dual versions (OPA2703 and OPA2704) are available in the MSOP-8,SO-8，and DIP-8 packages. The quad OPA4703 and OPA4704 are available in the TSSOP-14 and SO-14 pack-ages. All are specified for operation from – 40°C to +85°C.
