PRODUCT OVERVIEW

What Is the LT6105HDCB#TRMPBF?

LT6105HDCB#TRMPBF is a micropower, precision current sense amplifier from Analog Devices (formerly Linear Technology) designed for high‑temperature operation in a compact 6‑lead DFN package. It monitors unidirectional current by measuring the voltage drop across an external sense resistor, and is suitable for both high‑side and low‑side sensing in harsh environments.[reference:0]

The device features a very wide input common mode range that extends 44V above V– (independent of V+) and –0.3V below V–. This allows the LT6105HDCB#TRMPBF to continuously monitor current in positive supply rails, negative rails, and even batteries from full charge to depletion without compromising accuracy across the extended temperature range.[reference:1][reference:2]

Gain is configurable with external resistors, ranging from 1V/V to 100V/V.[reference:3] With CMRR exceeding 100dB and input offset voltage below 300µV, the LT6105HDCB#TRMPBF ensures high‑precision current measurement for demanding automotive, industrial, and high‑temperature systems.[reference:4]

Ultra‑Wide Common Mode –0.3V to 44V above V–, independent of V+, supports high‑side and low‑side sensing.

High Accuracy 300µV max input offset voltage, 1% max gain error.

Extended Temperature Guaranteed operation from –40°C to +125°C for harsh environments.

DEVICE HIGHLIGHTS

Key Features and Benefits of LT6105HDCB#TRMPBF

Over-the-Top® Wide Common Mode

Common mode range extends 44V above V– (independent of V+) and –0.3V below V–, enabling high‑side, low‑side, and negative rail current sensing without extra level shifters.[reference:5]

High Precision & Low Offset

300µV max input offset voltage and 1% max gain error ensure accurate amplification of small differential signals, reducing measurement uncertainty.[reference:6]

Configurable Gain

Gain can be set from 1V/V to 100V/V using two external resistors, providing flexibility for various sense resistor values and full‑scale output requirements.[reference:7]

Wide Supply Voltage Range

Operates from 2.85V to 36V single supply, compatible with 3V, 5V, 12V, and 24V systems.[reference:8]

Ultra‑Low Power Consumption

Quiescent current is only 150µA; sense input current drops to 1nA when powered down, ideal for battery‑powered and energy‑efficient designs.[reference:9][reference:10]

Extended Temperature Range

Guaranteed operation from –40°C to +125°C, making it suitable for automotive, industrial, and other high‑temperature environments.[reference:11]

DESIGN REFERENCE

Gain Setting and Circuit Considerations for LT6105HDCB#TRMPBF

Gain Setting

The LT6105HDCB#TRMPBF gain is set by external resistors R_IN and R_OUT. The gain equation is:

A_V = R_OUT / R_IN

Select R_IN and R_OUT to achieve gains from 1V/V to 100V/V.[reference:27]
Example: R_IN = 100Ω, R_OUT = 4.99kΩ gives a gain of ~50V/V.[reference:28]
Use precision resistors to maintain gain accuracy.

PCB and Power‑Supply Guidance

Current sense amplifier performance depends on layout, bypassing, input routing, and placement of external components.

Place a supply bypass capacitor close to the V+ and V– pins.
Place the sense resistor (R_SENSE) close to the +IN and –IN pins, using Kelvin connections to minimize parasitic resistance.
Keep input traces short and away from noisy digital signals.
The exposed pad on the bottom of the DFN package (Pin 7) is connected to V– and should be soldered to the PCB for proper thermal and electrical performance.[reference:29][reference:30]
Verify the recommended PCB footprint from the official datasheet before production.
