Product details
Overview
LTC6101HVAHMS8#PBF from Analog Devices is a high-voltage, high-side current sense amplifier in 8-lead MSOP package, operating from 5V to 100V supply, featuring ±300µV max input offset voltage, 1µs response time, and 118dB min PSRR. It converts shunt voltage into ground-referenced output current for precision battery monitoring and industrial power management systems.
For engineers reviewing the LTC6101HVAHMS8#PBF datasheet, LTC6101HVAHMS8#PBF pinout, LTC6101HVAHMS8#PBF application, or LTC6101HVAHMS8#PBF equivalent, key selection criteria include high common-mode voltage support (up to 100V), low quiescent current (230µA at 12V), gain configurability via external resistors, and –40°C to 125°C operating temperature range.
Technical Context
The LTC6101HVAHMS8#PBF uses a high-impedance feedback loop to force –IN to match +IN potential, enabling precise current sensing across an external shunt. Its transconductance architecture (IOUT = VSENSE/RIN) decouples gain setting from common-mode rejection, preserving accuracy at high voltages.
It delivers current-mode output (max 1mA) converted to voltage via external ROUT, supporting configurable gain (e.g., 20–100×) and maintaining 140kHz bandwidth at 200µA load. Input bias current is limited to 170nA max, minimizing error in high-RIN configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5V to 100V - supports direct sensing in 48V telecom, 72V EV auxiliary, and industrial 96V bus systems without level-shifting. |
| Input Offset Voltage | ±300µV max - enables use of small-value shunts (e.g., 5mΩ) while maintaining <1% error at 1A load. |
| Response Time | 1µs (to 2.5V on 5V step) - suitable for fast overcurrent detection and real-time load protection. |
| PSRR | 118dB min - rejects supply ripple even under noisy 100V rail conditions, critical for stable ADC interfacing. |
| Supply Current | 230µA typical at 12V - reduces self-heating and system power budget impact in always-on monitoring. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, industrial motor drives, and outdoor power equipment. |
| Input Sense Range | 500mV full-scale - accommodates wide current ranges (e.g., 100mA–20A) with single shunt resistor. |
Pinout & Package
Package: 8-Lead Plastic MSOP (3mm × 3mm, 1.1mm height), HV-optimized creepage/clearance spacing per LTC6101HV series requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: –IN | Inverting input of internal sense amplifier | Driven to same potential as +IN; connects to high-side shunt terminal via Kelvin trace to reject PCB resistance error. |
| 2: V– | Negative supply / ground reference | Serves as output current sink reference and system ground return; must be low-impedance for stable output voltage. |
| 3: NC | No connect | Internally unused; left floating or grounded per layout best practice-no electrical function. |
| 4: OUT | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate VOUT = IOUT × ROUT. |
| 5: +IN | Non-inverting input | Connects directly to load-side shunt terminal; high-impedance node minimizes loading error on sense resistor. |
| 6: V+ | Positive supply input | Accepts 5V–100V; supplies internal circuitry and defines common-mode range; current drawn here excludes load current unless configured for total-current sensing. |
| 7: NC | No connect | Internally unused; no connection required. |
| 8: NC | No connect | Internally unused; no connection required. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage operation | 100V supply rating with 105V absolute maximum - eliminates need for external regulators or dividers in 48V/72V/96V systems. |
| Configurable gain | Set via two external resistors (RIN, ROUT) - enables precise scaling (e.g., 250mV/A or 2.5V/A) without changing IC. |
| Low input bias current | 170nA max - ensures <0.17mV error with 1kΩ RIN, critical for high-gain, low-current sensing. |
| Fast transient response | 1µs rise time - supports real-time fault detection in UPS, server PSUs, and motor controllers. |
| Wide temperature range | –40°C to 125°C operation - meets AEC-Q100 Grade 1 and industrial extended-range requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40056ASA+T | 5.5V–65V supply range; 120µV max offset; 2.5µs response; SO-8 package | Limited to ≤65V systems; lower offset but slower response; lacks 100V capability | Preferred for cost-sensitive 24V/48V industrial controls where 100V headroom is unnecessary. |
| INA240A1D | 2.7V–80V supply; 20µV max offset; 1.5µs response; SO-8 package; integrated RIN | Lower offset and wider low-voltage range, but 80V max limits use in 96V battery systems | Best for precision 12V–48V battery monitors requiring ultra-low offset, accepting reduced HV margin. |

FAQ
What is the absolute maximum supply voltage for LTC6101HVAHMS8#PBF?
The absolute maximum supply voltage (V+ to V–) for LTC6101HVAHMS8#PBF is 105V, with recommended operating range from 5V to 100V. Exceeding 105V risks permanent damage per Absolute Maximum Ratings table in the datasheet. This rating enables direct integration into 96V battery systems without external voltage clamping.
Can LTC6101HVAHMS8#PBF measure bidirectional current?
No, LTC6101HVAHMS8#PBF is a unidirectional high-side current sense amplifier optimized for positive current flow from V+ through the shunt to load. Its architecture forces –IN to track +IN and sources output current proportional to VSENSE; it does not support negative VSENSE or reverse current detection.
What is the minimum sense resistor value usable with LTC6101HVAHMS8#PBF at 100V supply?
Minimum sense resistor is determined by maximum allowable VSENSE (500mV) and peak load current. For example, at 100A peak, RSENSE ≥ 5mΩ avoids exceeding 500mV. Layout Kelvin connections and 170nA input bias current further constrain practical minimums to ≥2mΩ in precision designs using LTC6101HVAHMS8#PBF.
How does LTC6101HVAHMS8#PBF achieve high PSRR without trimming?
LTC6101HVAHMS8#PBF achieves 118dB min PSRR through proprietary high-voltage complementary bipolar process and fully differential internal topology that inherently rejects supply variations. No external capacitors or trimming are required-PSRR remains stable across 5V–100V supply range and –40°C to 125°C temperature.
Is LTC6101HVAHMS8#PBF pin-compatible with other LTC6101HV variants in MSOP package?
Yes, all LTC6101HV MSOP variants-including LTC6101HVAHMS8#PBF, LTC6101HVAIMS8#PBF, and LTC6101HVACMS8#PBF-share identical 8-pin MSOP pinout and footprint. Only temperature grade (H = –40°C to 125°C) and initial offset grade (A/B/C) differ; no PCB redesign is needed when upgrading within the HV family.
