SBOS278B − SEPTEMBER 2003 − REVISED JANUARY 2004

Very Low Noise, High-Speed, 12V CMOS

Operational Amplifier

F_DEATURES

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

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).

BANDWIDTH: 20MHz

SLEW RATE: 30V/µs

FAST 16-BIT SETTLING TIME

LOW NOISE: 6nV/√Hz (typ) at 100kHz

EXCELLENT CMRR, PSRR, and A

RAIL-TO-RAIL OUTPUT

The 20MHz

CM RANGE INCLUDES GND

THD+N: 0.0003% (typ) at 1kHz

QUIESCENT CURRENT: 5.5mA/ch (max)

SUPPLY VOLTAGE: 4V to 12V

SHUTDOWN MODE (OPAx726): 6µA/ch

Excellent ac characteristics, such as 20MHz GBW, 30V/µs

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.

TEST EQUIPMENT

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 6µA and feature a reference pin for

easy shutdown operation with standard CMOS logic in

dual-supply applications.

OPA725 RELATED PRODUCTS

FEATURES

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°C to +125°C.
