Operational Amplifier  
FD EATURES  
DESCRIPTION  
The OPA725 and OPA726 series op amps use a  
state-of-the-art 12V analog CMOS process, and combine  
outstanding ac performance with low bias current and  
excellent CMRR, PSRR, and AOL  
Gain-Bandwidth (GBW) Product is achieved by using a  
proprietary and patent-pending output stage design.  
These characteristics allow excellent 16-bit settling times  
for driving 16-bit Analog-to-Digital converters (ADCs).  
BANDWIDTH: 20MHz  
SLEW RATE: 30V/µs

THD+N: 0.0003% (typ) at 1kHz  
QUIESCENT CURRENT: 5.5mA/ch (max)  
SUPPLY VOLTAGE: 4V to 12V  
SHUTDOWN MODE (OPAx726): 6µA/ch  
Excellent ac characteristics, such as 20MHz GBW, 30V/µs  
slew rate and 0.0003% THD+N make the OPA725 and  
OPA726 well-suited for communication, high-end audio,  
and active filter applications. With a bias current of less  
than 200pA, they are well-suited for use as  
transimpedance (I/V-conversion) amplifiers for monitoring  
optical power in ONET applications.

TEST EQUIPMENT  
The OPA725 and OPA726 op amps can be used in  
single-supply applications from 4V up to 12V, or  
dual-supply from 2V to 6V. The output swings to within  
150mV of the rails, maximizing dynamic range. The  
shutdown versions (OPAx726) reduce the quiescent  
current to less than 6µA and feature a reference pin for  
easy shutdown operation with standard CMOS logic in  
dual-supply applications.

FEATURES  
The OPA725 (single) is available in SOT23-5 and SO-8  
packages, and the OPA2725 (dual) is available in MSOP-8  
and SO-8 packages. The OPA726 (single with shutdown)  
is available in MSOP-8 and SO-8. The OPA2726 (dual with  
shutdown) is available in MSOP-10. All versions are  
specified for operation from −40°C to +125°C.
