FEATURES

DESCRIPTION

•

OFFSET: 15µV (typ), 150µV (max)

DRIFT: 0.3µV/°C (typ), 1.5µV/°C (max)

BANDWIDTH: 20MHz

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 and OPA728 family is trimmed over

temperature. The devices feature very high CMRR

and open-loop gain to minimize errors.

SLEW RATE: 30V/µs

BIAS CURRENT: 500pA (max)

LOW NOISE: 6nV/√Hz at 100kHz

THD+N: 0.0003% at 1kHz

QUIESCENT CURRENT: 4.3mA/ch

SUPPLY VOLTAGE: 4V to 12V

SHUTDOWN MODE (OPA728): 6µA

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 500pA, they are well suited

for use as transimpedance (I/V-conversion)

amplifiers for monitoring optical power in ONET

applications.

APPLICATIONS

•

OPTICAL NETWORKING

TRANSIMPEDANCE AMPLIFIERS

INTEGRATORS

ACTIVE FILTERS

A/D CONVERTER DRIVERS

I/V CONVERTER FOR DACs

HIGH PERFORMANCE AUDIO

PROCESS CONTROL

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.
