LMP8645/LMP8645HV Precision High Voltage Current Sense Amplifier January 7, 2010 LMP8645/LMP8645HV Precision High Voltage Current Sense Amplifier Ge.
The LMP8645 and the LMP8645HV are precision current sense amplifiers that detect small differential voltages across a sense resistor in the presence o.
Features
* Typical values, TA = 25°C
* High common-mode voltage range -2V to 42V
* LMP8645 -2V to 76V
* LMP8645HV 2.7V to 12V
* Supply voltage range
* Gain configurable with a single resistor
* Max variable gain accuracy (with external resistor) 2.0% 200 μA/V
* Transconducta
Applications
* where supply current and high common mode voltage are the determining factors. The gain is configured with a single resistor, providing a high level of flexibility, the accuracy could be as low as 2% (max) including the gain setting resistor. The output is buffered in order to provide low output imp
