LT1997-3 - Single Supply Current Sense

Jun 14th 2017
Sense resistors R1 converts a current into a voltage. This voltage is buffered (gain of 1) from the input to the output in this amplifier. V1 tests the circuit for response to common mode variation. A simulation will show that the output voltage variation due to the common mode voltage V1 is very small.     The ...

LT1997-3 - Conversion of Single Ended Pulse To Differential Output

Jun 14th 2017
This circuit combines the LT®1997-3 with a high speed amplifier to convert a single-ended signal to differential with a common-mode offset. Extra compensation capacitors C1 and C2 help to shape the final response. Taking higher gain from the LT1997-3 will eliminate the need for these capacitors.     The LT1997-3 ...
