3 Description
The OPA210 and OPA2210 (OPAx210) are the next
generation of OPAx209 operational amplifier (op
amp). The OPAx210 precision op amps are built
on TI's precision, super-beta, complementary bipolar
semiconductor process, which offers ultra-low flicker
noise, low offset voltage, and low offset voltage
temperature drift.
The OPAx210 achieve very low voltage noise
density (2.2 nV/√Hz) while consuming only 2.5 mA
(maximum) per amplifier. These devices also offer
rail-to-rail output swing, which helps maximize
dynamic range.
In precision data-acquisition applications, the
OPAx210 provide fast settling time to 16-bit
accuracy, even for 10-V output swings. Excellent ac
performance, combined with only 35 μV (maximum)
of offset and 0.6 μV/°C (maximum) drift over
temperature, makes the OPAx210 an excellent choice
for high-speed, high-precision applications.
The OPAx210 are specified over a wide dual powersupply
range of ±2.25 V to ±18 V, or single-supply
operation from 4.5 V to 36 V, are specified from –40°C
to +125°C.
