Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix HVAHMS8 against the manufacturer's official documentation to confirm the grade, package type, and temperature range. Ensure the ordering information matches the required specifications for your design. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-side current sensing is required with a common-mode voltage exceeding standard operational limits. The low offset voltage allows for smaller sense resistors, reducing power loss. Verify that the external resistor values maintain the output current within the 1mA limit while providing the necessary voltage swing for the downstream ADC or comparator.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC6101 family of high-voltage current sense amplifiers. It shares core functionality with the standard LTC6101 but supports higher supply voltages up to 100V. The MS8 package offers a compact footprint compared to larger packages, making it suitable for space-constrained designs requiring precise current monitoring in high-voltage environments.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the maximum common-mode voltage supported by this amplifier?

The LTC6101HV variant supports a supply voltage range from 5V to 100V, allowing for high-side current sensing at these potentials.

How is the gain of the amplifier configured?

The gain is set by two external resistors, RIN and ROUT, where the output voltage is determined by the ratio of these resistors multiplied by the sense voltage.
