LTC6102MS8#PTPBF

LTC6102 is a precision zero-drift high-side current sense amplifier developed by Analog Devices. I stands for industrial wide temperature grade specification. MS8 refers to 8-lead compact MSOP surface mount package. #PBF denotes lead-free bulk tube packaging for prototype testing and small-batch production assembly.

This high-voltage current sensing IC is designed for high-side current monitoring across wide voltage bus rails. It measures voltage drop across an external shunt resistor, then converts the differential sensing voltage into ground-referenced output current, enabling accurate current measurement under large common-mode voltage conditions.

The device operates from 4V to 60V supply voltage with absolute maximum rating up to 70V. It features ultra-low input offset voltage of maximum ±10μV and offset drift limited to ±50nV/°C, delivering consistent measurement precision throughout the full temperature range and permitting the use of low-value shunt resistors to minimize power dissipation.

Gain is freely programmable via two external resistors to meet diverse current detection ranges. It achieves 1μs fast step response, suitable for rapid overcurrent protection and load transient monitoring scenarios. Key electrical specifications include maximum 3nA input bias current, minimum 130dB power supply rejection ratio, and up to 1mA sourcing output current. No built-in shutdown pin is equipped on this standard version, keeping standby quiescent current stable for continuous monitoring tasks.

Packaged in miniature 8-pin MSOP surface mount housing with tiny footprint, which greatly saves PCB layout space for compact power management modules. Moisture Sensitivity Level is MSL1, there is no time restriction for reflow soldering after vacuum packaging is opened. Tube delivery is adopted to support manual breadboard debugging and small-volume prototype fabrication conveniently.

Industrial operating temperature range covers -40°C to +125°C, capable of stable continuous operation in industrial power supplies, new energy equipment, vehicle electronic control units and automated test systems with severe temperature fluctuation. Manufactured with lead-free materials, the component complies with global RoHS environmental directives. The current-output architecture simplifies peripheral signal conversion circuits and enhances anti-interference capability in noisy industrial electromagnetic environments.
