DESCRIPTION

10MHz, Rail-to-Rail

Input and Output

Op Amp in SOT-23

The LT®1797 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.
