APPLICATIU
The LT
1797 is a unity-gain stable 10MHz op amp avail-
able in the small SOT-23 package that operates on all
single and split supplies with a total voltage of 2.7V to 12V.
The amplifier draws 1mA of quiescent current and has a
slew rate of 2.25V/
μ
s.
The input common mode range of the LT1797 includes
both rails, making it ideal for current sensing applications.
The input stage incorporates phase reversal protection to
prevent false outputs from occurring when the inputs are
driven beyond the supplies. Protective resistors are in-
cluded in the input leads so that current does not become
excessive when the inputs are forced above or below the
supplies.
The output of the LT1797 can swing to within 50mV of V
+
and 8mV of V
without drawing excess current in either
condition. The amplifier can drive loads up to 25mA and
still maintain rail-to-rail capability.
The LT1797 op amp is available in the space saving 5-lead
SOT-23 package.
