SBOS377A – OCTOBER 2006 – REVISED FEBRUARY 2007

1.1nV/

√Hz Noise, Low Power, Precision

Operational Amplifier in Tiny DFN-8 Package

• LOW-VOLTAGE NOISE: 1.1nV/√Hz at 1kHz

The OPA211 series achieves very low 1.1nV/

√Hz

noise density with a supply current of only 3.6mA. It

• 100nV

also offers rail-to-rail output swing, which helps to

• LOW OFFSET VOLTAGE: 100µV (max)

maximize dynamic range.

• LOW OFFSET VOLTAGE DRIFT: 0.2µV/°C (typ)

The OPA211 series’ extremely low voltage and

• LOW SUPPLY CURRENT: 3.6mA/Ch

current noise, high speed and wide output swing

• UNITY GAIN STABLE

make it an excellent choice as a loop filter amplifier

in PLL applications.

• GAIN BANDWIDTH PRODUCT:

80MHz (G = 100)

applications,

the

• SLEW RATE: 27V/µs

OPA211 series of op amps provide <1

µs settling

time to 16-bit accuracy even for 10V output swings.

• WIDE SUPPLY RANGE:

This ac performance, combined with only 100

µV of

±2.25V to ±18V, +4.5V to +36V

offset and low drift over temperature, make the

digital-to-analog converters (DACs).

• AVAILABLE IN TINY DFN-8 (3x3mm), MSOP-8,

The OPA211 is specified over the very wide

SO-8

dual-power supply range of

±2.25V to ±18V, or

single-supply operation from +4.5V to +36V.

• PLL LOOP FILTER

The OPA211 is available in the tiny DFN-8 (3

×3mm)

and MSOP-8 and SO-8 packages. A dual version,
