DESCRIPTIO

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.
