• LOW VOLTAGE NOISE: 1.1nV/√Hz at 1kHz
The
OPA211
series
of
precision
operational
amplifiers achieves very low 1.1nV/
√Hz noise density
• INPUT VOLTAGE NOISE:
with a supply current of only 3.6mA. This series also
80nVPP (0.1Hz to 10Hz)
offers rail-to-rail output swing, which maximizes
• THD+N: –136dB (G = 1, f = 1kHz)
dynamic range.
• OFFSET VOLTAGE: 125µV (max)
The extremely low voltage and low current noise,
• OFFSET VOLTAGE DRIFT: 0.35µV/°C (typ)
high speed, and wide output swing of the OPA211
• LOW SUPPLY CURRENT: 3.6mA/Ch (typ)
series make these devices an excellent choice as a
loop filter amplifier in PLL applications.
• UNITY-GAIN STABLE
• GAIN BANDWIDTH PRODUCT:
In
precision
data
acquisition
applications,
the
OPA211 series of op amps provides 700ns settling
80MHz (G = 100)
time to 16-bit accuracy throughout 10V output swings.
45MHz (G = 1)
This ac performance, combined with only 125
µV of
• SLEW RATE: 27V/µs
offset and 0.35
µV/°C of drift over temperature, makes
• 16-BIT SETTLING: 700ns
the OPA211 ideal for driving high-precision 16-bit
analog-to-digital converters (ADCs) or buffering the
• WIDE SUPPLY RANGE:
output of high-resolution digital-to-analog converters
±2.25V to ±18V, +4.5V to +36V
(DACs).
• RAIL-TO-RAIL OUTPUT
The
OPA211
series
is
specified
over
a
wide

dual-power supply range of ±2.25V to ±18V, or for
• DFN-8 (3mm × 3mm), MSOP-8, AND SO-8
single-supply operation from +4.5V to +36V.
The OPA211 is available in the small DFN-8 (3mm ×
3mm), MSOP-8, and SO-8 packages. A dual version,
