LOW VOLTAGE NOISE: 2.2nV/√Hz at 1kHz
The OPA209 series of precision operational
amplifiers achieve very low voltage noise density
(2.2nV/√Hz) with a supply current of only 2.5mA
(max). This series also offers rail-to-rail output swing,
which helps to maximize dynamic range.
0.1Hz to 10Hz NOISE: 130nVPP
LOW QUIESCENT CURRENT: 2.5mA/Ch (max)
LOW OFFSET VOLTAGE: 150mV (max)
GAIN BANDWIDTH PRODUCT: 18MHz
SLEW RATE: 6.4V/ms
In precision data acquisition applications, the
OPA209 provides fast settling time to 16-bit accuracy,
even for 10V output swings. This excellent ac
performance, combined with only 150mV (max) of
offset and low drift over temperature, makes the
OPA209 very suitable for fast, high-precision
applications.
WIDE SUPPLY RANGE:
±2.25V to ±18V, +4.5V to +36V

RAIL-TO-RAIL OUTPUT
SHORT-CIRCUIT CURRENT: ±65mA
AVAILABLE IN SOT23-5, MSOP-8, SO-8, AND
TSSOP-14 PACKAGES
The OPA209 is specified over
a
wide dual
power-supply range of ±2.25 to ±18V, or
single-supply operation from +4.5V to +36V.
APPLICATIONS
The OPA209 is available in the SOT23-5, MSOP-8
and the standard SO-8 packages. The dual OPA2209
comes in both MSOP-8 and SO-8 packages. The
quad OPA4209 is available in the TSSOP-14
package.
