FEATURES

LT1881/LT1882

Dual and Quad

Rail-to-Rail Output, Picoamp

Input Precision Op Amps

DESCRIPTION

The LT

1881 and LT1882 op amps bring high accuracy

input performance to ampliﬁers with rail-to-rail output

swing. Input bias currents and capacitive load driving

capabilities are superior to the similar LT1884 and LT1885

ampliﬁers, at the cost of a slight loss in speed. Input

offset voltage is trimmed to less than 50μV and the

low drift maintains this accuracy over the operating

temperature range. Input bias currents are an ultralow

200pA maximum.

The ampliﬁers work on any total power supply voltage

between 2.7V and 36V (fully speciﬁed from 5V to ±15V).

Output voltage swings to within 40mV of the negative

supply and 220mV of the positive supply make these

ampliﬁers good choices for low voltage single supply

operation.

Capacitive loads up to 1000pF can be driven directly in

unity-gain follower applications.

The dual LT1881 and LT1881A are available with standard

pinouts in S8 and PDIP packages. The quad LT1882 is in a

14-pin SO package. For a higher speed device with similar

DC speciﬁcations, see the LT1884/LT1885.
