OPA705
SBOS182A – JUNE 2001
Low-Cost, CMOS, Rail-to-Rail, I/O
OPERATIONAL AMPLIFIERS
FEATURES
DESCRIPTION
● RAIL-TO-RAIL INPUT AND OUTPUT
The OPA705 series low-cost op amps are optimized for appli-
cations 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 OPA705 still offers excellent dynamic performance
(1MHz GBW and 0.6V/µs SR) and unity-gain stability.
● WIDE SUPPLY RANGE:
Single Supply: 4V to 12V
Dual Supplies: ±2 to ±6
● LOW QUIESCENT CURRENT: 160µA
● LIMITED RANGE CMRR: 96dB
● LOW OFFSET: 0.5mV
The OPA705 series is 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.
● HIGH SPEED: 1MHz, 0.6V/µs
● MicroSIZE PACKAGES:
SOT23-5, MSOP-8, TSSOP-14
The single version (OPA705) is available in the MicroSIZE
SOT23-5 and in the standard SO-8 surface-mount packages.
The dual version (OPA2705) is available in the MSOP-8,
SO-8, and DIP-8 packages. The quad OPA4705 is available
in the TSSOP-14 and SO-14 packages. All are specified for
operation from –40°C to +85°C.
● LOW INPUT BIAS CURRENT: 1pA
APPLICATIONS
● AUTOMOTIVE APPLICATIONS:
