This is the tube-packaged version of the LT6105IDCB#TRPBF (which uses tape and reel). The device is electrically identical in all respects. The LT6105 measures the voltage across an external sense resistor placed in the high-side power path and provides a ground-referenced output voltage proportional to the load current. The 105V maximum common mode supports high-voltage battery and industrial supply monitoring. The 1MHz bandwidth enables fast overcurrent detection for power supply protection. The +\/-0.3% gain accuracy and 100 dB CMRR provide precise measurement even with large common mode swings. The external gain resistors allow flexible output scaling to match the ADC input range.","working_principle":"The LT6105IDCB operates identically to the LT6105IDCB#TRPBF. It uses a precision difference amplifier with internal level-shifting to measure the differential voltage across an external sense resistor while rejecting the high common mode voltage. The internal attenuator divides the common mode voltage to within the amplifier's input range, while the differential signal is preserved and amplified. The output voltage is VOUT = ISENSE x RSENSE x (ROUT\/RIN), where RIN and ROUT are external gain-setting resistors. The 100 dB CMRR is maintained by laser-trimmed resistor matching. The 1 MHz bandwidth allows the device to track rapidly changing current waveforms such as those in switching power supplies and motor drives.","pin_description":"
