DESCRIPTIO
SOT-23, Rail-to-Rail Output,
ThinSOT is a trademark of Linear Technology Corporation.
The LT
mance and rail-to-rail output swing to the SOT-23 pack-
age. Input offset voltage is trimmed to less than 150 V and
the low drift maintains this accuracy over the operating
temperature range. Input bias current is an ultra low
900pA maximum.
The amplifier works on any total power supply voltage
between 2.7V and 36V (fully specified from 5V to 15V).
Output voltage swings to within 55mV of the negative
supply and 250mV of the positive supply, which makes the
amplifier a good choice for low voltage single supply
operation.
Slew rates of 0.4V/ s with a supply current of 1.2mA give
superior response and settling time performance in a low
power precision amplifier.
The LT1880 is available in a 5-lead SOT-23 package.
