3 Description

The

OPA2188

operational

amplifier

uses

TI

proprietary auto-zeroing techniques to provide low

offset voltage (25 μV, maximum), and near zero-drift

over time and temperature. This miniature, high-

precision, low quiescent current amplifier offers high

input impedance and rail-to-rail output swing within 15

mV of the rails. The input common-mode range

includes the negative rail. Either single or dual

supplies can be used in the range of 4 V to 36 V (±2

V to ±18 V).

The OPA2188 device is available in MSOP-8 and

SO-8 packages. The device is specified for operation

from –40°C to +105°C.
