LT1884/LT1885

The LT
1884/LT1885 op amps bring high accuracy input
performance to amplifiers with rail-to-rail output swing
while providing faster response than other precision am-
plifiers. Input offset voltage is trimmed to less than 50
V
and the low drift maintains this accuracy over the operat-
ing temperature range. Input bias currents are an ultralow
400pA 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.
Slew rates of 1V/
s with a supply current of less than 1mA
per amplifier give superior response and settling time
performance in a low power precision amplifier.
The dual LT1884 is available with standard pinouts in
8-pin SO and PDIP packages. The quad LT1885 is also in
the standard pinout 14-pin SO package.
