DESCRIPTION
The LT
1782 is a 200kHz op amp available in the small
®
SOT-23 package that operates on all single and split sup-
plies with a total voltage of 2.5V to 18V. The amplifier
draws less than 55µA of quiescent current and has reverse
battery protection, drawing negligible current for reverse
supply voltages up to 18V.
The input range of the LT1782 includes ground, and a
unique feature of this device is its Over-The-Top™ opera-
tion capability 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 LT1782 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
LT1782 op amp is available in the 5- and 6-lead SOT-23
packages. For applications requiring higher speed, refer
to the LT1783.
