LT1784
2.5MHz, Over-The-Top
Low Power, Rail-to-Rail Input
and Output Op Amp in SOT-23
DESCRIPTION
The LT
®
1784 is a 2.5MHz 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 amplifier draws less
than 750μA of quiescent current and has reverse battery
protection, drawing negligible current for reverse supply
voltages up to 18V.
The input range of the LT1784 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 LT1784 can drive loads up to 15mA 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
LT1784 op amp is available in the 5- and 6-lead SOT-23
packages. For applications requiring lower power, refer to
the LT1782 and LT1783 data sheets.
