TYPICAL APPLICATION
DESCRIPTION
SOT-23, Rail-to-Rail Output,
Picoamp Input Current
Precision Op Amp
The LT
®
1880 op amp brings high accuracy input perfor-
mance and rail-to-rail output swing to the SOT-23 package.
Input offset voltage is trimmed to less than 150μV and
the low drift maintains this accuracy over the operating
temperature range. Input bias current is an ultralow 900pA
maximum.
The amplifi er works on any total power supply voltage
between 2.7V and 36V (fully specifi ed from 5V to ±15V).
Output voltage swings to within 55mV of the negative
supply and 250mV of the positive supply, which makes
the amplifi er a good choice for low voltage single supply
operation.
Slew rates of 0.4V/μs with a supply current of 1.2mA give
superior response and settling time performance in a low
power precision amplifi er.
The LT1880 is available in a 5-lead SOT-23 package.
