3 Description
The OPAx188-Q1 operational amplifier family uses
TI's proprietary zero drift 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 family 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 from 4 V to 36 V
(±2 V to ±18 V).
The OPA188-Q1 and OPA2188-Q1 are both offered
in VSSOP-8. The single-channel version
(OPA188-Q1) is fully specified from –40°C to +125°C,
and the dual-channel version (OPA2188-Q1) is fully
specified from –40°C to +105°C.
