DESCRIPTIO

The LT

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/ 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

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.
