DESCRIPTION
The OPA727 and OPA728 series op amps use a
state-of-the-art 12V analog CMOS process and e-trim, a
package-level trim, offering outstanding dc precision and
ac performance. The extremely low offset (150µV max)
and drift (1.5µV/°C) are achieved by trimming the IC
digitally after packaging to avoid the shift in parameters as
a result of stresses during package assembly. To correct
for offset drift, the OPA727/OPA728 family is trimmed over
temperature. The devices feature very high CMRR and
open loop gain to minimize errors.
Excellent ac characteristics, such as 20MHz GBW, 30V/µs
slew rate and 0.0003% THD+N make the OPA727 and
OPA728 well-suited for communication, high-end audio,
and active filter applications. With a bias current of less
than 100pA, they are ideal for use as transimpedance
(I/V-conversion) amplifiers for monitoring optical power in
ONET applications.
Optimized for single-supply operation up to 12V, the input
common-mode range extends to GND for true
single-supply functionality. The output swings to within
150mV of the rails, maximizing dynamic range. The low
quiescent current of 4.3mA makes it well-suited for use in
battery-operated equipment. The OPA728 shutdown
version reduces the quiescent current to typically 6µA and
features a reference pin for easy shutdown operation with
standard CMOS logic in dual-supply applications.
For ease of use, the OPA727 and OPA728 op amp families
are fully specified and tested over the supply range of 4V
to 12V. The OPA727 (single) and OPA728 (single with
shutdown) are available in MSOP-8 and DFN-8; the
OPA2727 (dual) is available in DFN-8 and SO-8, and the
quad version OPA4727 will be available Q1’05 in
TSSOP-14. All versions are specified for operation from
−40°C to +125°C.
