e-trim™ 20MHz, High Precision CMOS

Operational Amplifier

• OFFSET: 15µV (typ), 150µV (max)

The OPA727 and OPA728 series op amps use a

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

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

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

• BANDWIDTH: 20MHz

precision and ac performance. The extremely low

• SLEW RATE: 30V/µs

offset (150

µV max) and drift (1.5µV/°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

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): 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

(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

well-suited for use in battery-operated equipment.
