- Zero-drift architecture with 50 µV maximum input offset voltage delivers precise current measurements across temperature without calibration
- Ultra-low 0.02 µA maximum input bias current minimizes measurement errors when using high-value sense resistors
- Hardware shutdown pin reduces system quiescent current during sleep modes, extending battery life in portable and IoT applications
Applications
The LTC6102HMS8-1#TRPBF is suited for high-side current sensing in battery management systems, motor drive control, and industrial power monitoring where measurement accuracy and low self-heating are critical. Its zero-drift topology maintains 50 µV offset stability over temperature, making it reliable for precision coulomb-counting and load-current protection in automotive and medical equipment. The shutdown feature also makes it attractive for duty-cycled IoT sensor nodes that must minimize quiescent power draw.

Frequently Asked Questions
What is the input offset voltage specification of the LTC6102HMS8-1#TRPBF and why does it matter for current sensing accuracy?
The LTC6102HMS8-1#TRPBF has a maximum input offset voltage of 50 µV, which directly limits measurement error when the voltage drop across the sense resistor is small. For a 10 mΩ shunt carrying 1 A, the sense voltage is only 10 mV, so a 50 µV offset represents just 0.5% error — acceptable for most battery and motor current-monitoring applications without external calibration.
How does the shutdown feature of LTC6102HMS8-1#TRPBF help in duty-cycled IoT sensor designs?
The hardware shutdown pin disables the amplifier's internal circuitry when the node enters sleep mode, reducing quiescent current to near zero versus the active-mode supply draw. In an IoT sensor node that wakes every 10 seconds for a 50 ms measurement window, this can cut average power consumption by over 99%, directly extending battery runtime from months to years without sacrificing the 50 µV offset accuracy during active measurement intervals.
For a 48 V industrial motor drive, what sense resistor value works well with LTC6102HMS8-1#TRPBF given its 0.02 µA bias current?
With a 0.02 µA maximum input bias current, the LTC6102HMS8-1#TRPBF introduces negligible error even with sense resistors up to 10 kΩ (0.02 µA × 10 kΩ = 0.2 mV offset). For a 48 V motor drive measuring currents in the 1 A to 20 A range, a 1 mΩ to 5 mΩ shunt balances power dissipation and signal-to-noise ratio, while the MSOP-8 package keeps layout compact next to the high-current trace.
