3 Description

The

OPA4188

operational

amplifier

uses

TI

proprietary auto-zeroing techniques to provide low

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

over time and temperature. These miniature, high-

precision, low quiescent current amplifiers offer high

input impedance and rail-to-rail output swing within

15 mV of the rails, making them ideal for industrial

applications. 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 quad version is available in 14-pin SOIC and 14-

pin TSSOP packages. All versions are specified for

operation from –40°C to +125°C.
