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 ...

LTspice: Worst-Case Circuit Analysis with Minimal Simulations Runs

Joseph Spencer - Field Applications Engineer
Gabino Alonso - Strategic Marketing Engineer
Jun 8th 2017
When designing a circuit in LTspice, you may wish to assess the impact of component tolerances. For example, the gain error introduced by non-ideal resistors in an op amp circuit. This article illustrates a method that reduces the number of simulations needed, and as a result speeds your time to results. Varying a Parameter LTSpice ...

High-Voltage Amplifier Extends Coulomb Counter Range to +/-270V

Kris Lokere - Strategic Applications Manager Jan 22nd 2016
Introduction A coulomb counter can measure charge that flows into or out of a battery. Small, dedicated devices such as LTC2941 or LTC2943 can directly interface with low to medium battery voltages, up to about 20V. You can extend the input operating range of the measurement circuit by using a high-voltage amplifier as a level ...
