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.
