DESCRIPTIO
ThinSOT and Over-The-Top are trademarks of Linear Technology Corporation.
The LT
SOT-23 package that operates on all single and split
supplies with a total voltage of 2.5V to 18V. The amplifier
draws less than 300 A 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
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 5 A. The
LT1783 op amp is available in the 5- and 6-lead
SOT-23 packages. For applications requiring lower power,
refer to the LT1782.
