OPA890

SBOS369 – MAY 2007

Low-Power, Wideband, Voltage-Feedback

OPERATIONAL AMPLIFIER with Disable

• FLEXIBLE SUPPLY RANGE:

The OPA890 represents a major step forward in

+3V to +12V Single Supply

unity-gain stable, voltage-feedback op amps. A new

±1.5V to ±6V Dual Supplies

internal

architecture

provides

slew

rate

and

• UNITY-GAIN STABLE

full-power

bandwidth

previously

found

only

in

• WIDEBAND +5V OPERATION: 115MHz

wideband,

current-feedback

op

amps.

These

(G = +2V/V)

capabilities provide exceptional full power bandwidth.

Using a single +5V supply, the OPA890 can deliver a

• OUTPUT VOLTAGE SWING: ±4V

1V to 4V output swing with over 35mA drive current

• HIGH SLEW RATE: 500V/µs

and

220MHz

bandwidth.

This

combination

of

• LOW QUIESCENT CURRENT: 1.1mA

features makes the OPA890 an ideal RGB line driver

or single-supply analog-to-digital converter (ADC)

• LOW DISABLE CURRENT: 30µA

input driver.

The low 1.1mA supply current of the OPA890 is

• VIDEO LINE DRIVING

precisely trimmed at +25

°C. This trim, along with low

temperature drift, ensures lower maximum supply

• xDSL LINE DRIVERS/RECEIVERS

current than competing products. System power may

be reduced further using the optional disable control

• ADC BUFFERS

pin. Leaving this disable pin open, or holding it

• PORTABLE INSTRUMENTS

HIGH, operates the OPA890 normally. If pulled

LOW, the OPA890 supply current drops to less than

state.
