DESCRIPTION

Rail-to-Rail Output:

The OPA2180 and OPA4180 operational amplifiers

use zero-drift techniques to simultaneously provide

low offset voltage (75 μV), 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

18 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 +4.0 V to +36 V

(±2 V to ±18 V).

Input Includes Negative Rail

•

Low Bias Current: 250 pA (typ)

RFI Filtered Inputs

MicroSIZE Packages

The dual version is offered in MSOP-8 and SO-8

packages. The quad is offered in SO-14 and TSSOP-

14 packages. All versions are specified for operation

from –40°C to +105°C.
