12V, 7MHz, CMOS, Rail-to-Rail I/O  
OPERATIONAL AMPLIFIERS  
FEATURES  
DESCRIPTION  
● HIGH SPEED: 7MHz, 10V/µs  
The OPA743 series utilizes a state-of-the-art 12V analog  
CMOS process and offers outstanding AC performance,  
such as 7MHz GBW, 10V/µs slew rate and 0.0008% THD+N.  
Optimized for single supply operation up to 12V, the input  
common-mode range extends beyond the power supply rails  
and the output swings to within 100mV of the rails. The low  
quiescent current of 1.1mA makes it well suited for use in  
battery operated equipment.  
● RAIL-TO-RAIL INPUT AND OUTPUT  
● WIDE SUPPLY RANGE:  
Single Supply: 3.5V to 12V  
Dual Supplies: ±1.75V to ±6V  
● LOW QUIESCENT CURRENT: 1.1mA  
● FULL-SCALE CMRR: 84dB  
● MicroSIZE PACKAGES:  
The OPA743 series’ ability to drive high output currents  
together with 12V operation makes it particularly useful for  
use as gamma correction reference buffer in LCD panels.  
SOT23-5, MSOP-8, TSSOP-14  
● LOW INPUT BIAS CURRENT: 1pA  
For ease of use the OPA743 op-amp family is fully specified  
and tested over the supply range of ±1.75V to ±6V. Single,  
dual and quad versions are available.  
APPLICATIONS  
● LCD GAMMA CORRECTION  
The single versions (OPA743) are available in the MicroSIZE  
SOT23-5 and in the standard SO-8 surface-mount, as well as  
DIP-8 packages. Dual versions (OPA2743) are available ver-  
sions in the MSOP-8, SO-8, and DIP-8 packages. The quad  
versions (OPA4743) are available in the TSSOP-14 and SO-14  
packages. All are specified for operation from –40°C to +85°C.  
● AUTOMOTIVE APPLICATIONS:  
Audio, Sensor Applications, Security Systems  
● PORTABLE EQUIPMENT  
● ACTIVE FILTERS  
● TRANSDUCER AMPLIFIER  
● TEST EQUIPMENT  
● DATA ACQUISITION
