e-trim™ 20MHz, High Precision CMOS

Operational Amplifier

• OFFSET: 15 µ V (typ), 150 µ V (max)

The OPA727 and OPA728 series op amps use a

state-of-the-art 12V analog CMOS process and

• DRIFT: 0.3 µ V/ ° C (typ), 1.5 µ V/ ° C (max)

e-trim, a package-level trim, offering outstanding dc

• BANDWIDTH: 20MHz

precision and ac performance. The extremely low

• SLEW RATE: 30V/ µ s

offset (150 µ V max) and drift (1.5 µ V/ ° C) are achieved

• BIAS CURRENT: 500pA (max) by trimming the IC digitally after packaging to avoid

the shift in parameters as a result of stresses during

• LOW NOISE: 6nV/ √ Hz at 100kHz

package assembly. To correct for offset drift, the

• THD+N: 0.0003% at 1kHz

OPA727 and OPA728 family is trimmed over

• QUIESCENT CURRENT: 4.3mA/ch

temperature. The devices feature very high CMRR

and open-loop gain to minimize errors.

• SUPPLY VOLTAGE: 4V to 12V

• SHUTDOWN MODE (OPA728): 6 µ A Excellent ac characteristics, such as 20MHz GBW,

30V/ µ s 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

• OPTICAL NETWORKING

bias current of less than 500pA, they are well suited

• TRANSIMPEDANCE AMPLIFIERS

for use as transimpedance (I/V-conversion)

• INTEGRATORS

amplifiers for monitoring optical power in ONET

applications.

• ACTIVE FILTERS

• A/D CONVERTER DRIVERS

Optimized for single-supply operation up to 12V, the

• I/V CONVERTER FOR DACs

input common-mode range extends to GND for true

single-supply functionality. The output swings to

• HIGH PERFORMANCE AUDIO

within 150mV of the rails, maximizing dynamic range.

• PROCESS CONTROL

The low quiescent current of 4.3mA makes it

• TEST EQUIPMENT

well-suited for use in battery-operated equipment.

The OPA728 shutdown version reduces the

quiescent current to typically 6 µ A and features a

reference pin for easy shutdown operation with

standard CMOS logic in dual-supply applications.

20MHz, 3mV, 4 µ V/ ° C OPA725

(non-e-trim version of OPA727)

For ease of use, the OPA727 and OPA728 op amp

20MHz, 3mV, 4 µ V/ ° C, Shutdown OPA726

families are fully specified and tested over the supply

(non-e-trim version of OPA728)

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 in TSSOP-14. All versions are specified for

operation from –40 ° C to +125 ° C.

This output stage is capable of driving heavy loads connected to any point between V+ and V–. For light resistive loads (>100kΩ), the output voltage can swing to 150mV from the supply rail, while still maintaining excellent linearity (AOL > 110dB).
