FEATURES
DESCRIPTION
10MHz, Rail-to-Rail
Input and Output
Op Amp in SOT-23
The LT1797 is a unity-gain stable 10MHz op amp available
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/μs.
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
included 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.
