DESCRIPTION
1.25MHz, Over-The-Top
Micropower, Rail-to-Rail Input
and Output Op Amp in SOT-23
The LT
®
1783 is a 1.25MHz op amp available in the small
SOT-23 package that operates on all single and split supplies
with a total voltage of 2.5V to 18V. The amplifi er draws less
than 300μA of quiescent current and has reverse-battery
protection, drawing negligible current for reverse supply
voltages up to 18V.
The input range of the LT1783 includes ground, and a
unique feature of this device is its Over-The-Top
®
opera-
tion capabilitity with either or both of its inputs above the
positive rail. The inputs handle 18V both differential and
common mode, independent of supply voltage. The input
stage incorporates phase reversal protection to prevent
false outputs from occurring even when the inputs are 9V
below the negative supply.
The LT1783 can drive loads up to 18mA and still maintain
rail-to-rail capability. A shutdown feature on the 6-lead
version can disable the part, making the output high
impedance and reducing quiescent current to 5μA. The
LT1783 op amp is available in the 5- and 6-lead SOT-23
packages. For applications requiring lower power, refer
to the LT1782.
