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. The 20MHz
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).
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.
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.
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.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

(1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those specified is not supported.
(2) Input terminals are diode-clamped to the power-supply rails.
Input signals that can swing more than 0.5V beyond the supply
rails should be current limited to 10mA or less.
(3) Short-circuit to ground, one amplifier per package.
