LT1797 - 10MHz, Rail-to-Rail Input and Output Op Amp in SOT-23

Operational Amplifier, 1 Func, 3000uV Offset-Max, BIPolar, PDSO5

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.
