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 A
OL
. 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/
μ
s
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 6
μ
A 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
