DESCRIPTIO
The LT
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 tempera-
ture 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.
