LT1797

10MHz, Rail-to-Rail

Input and Output

Op Amp in SOT-23

FeaTures

DescripTion

TheLT^®1797isaunity-gainstable10MHzopampavailable

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.

Rail-to-Rail Input and Output

Small SOT-23 Package

Gain Bandwidth Product: 10MHz

–40°C to 85°C Operation

Slew Rate: 2.25V/µs

Low Input Offset Voltage: 1.5mV Max

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

includedintheinputleadssothatcurrentdoesnotbecome

excessive when the inputs are forced above or below the

supplies.

High Output Current: 25mA Min

Specified on 3V, 5V and 5V Supplies

High Voltage Gain: 1000V/mV 10k Load

High CMRR: 96dB Typ

High PSRR: 90dB Typ

Input Bias Current: 300nA Max

Input Offset Current: 25nA Max

Low Profile (1mm) SOT-23 (ThinSOT™) Package

The output of the LT1797 can swing to within 50mV of V

–

and 8mV of V without drawing excess current in either

applicaTions

condition. The amplifier can drive loads up to 25mA and

still maintain rail-to-rail capability.

Portable Instrumentation

Rail-to-Rail Buffer Amplifiers

The LT1797 op amp is available in the space saving 5-lead

SOT-23 package.
