Product details
Overview
LTC6101AHS5#TRPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, delivering ±85 µV max input offset voltage, 1 µs response time, and operation from 4 V to 60 V supply with –40°C to 125°C temperature rating. It converts shunt voltage into ground-referenced output current for precision battery monitoring and load protection in industrial power supplies.
For engineers reviewing the LTC6101AHS5#TRPBF datasheet, LTC6101AHS5#TRPBF pinout, LTC6101AHS5#TRPBF application, or LTC6101AHS5#TRPBF equivalent, key selection criteria include input offset drift (±1 µV/°C), PSRR (118 dB min), gain configurability via external RIN/ROUT, low 250 µA supply current at 12 V, and SOT-23 thermal performance (θJA = 250°C/W).
Technical Context
The LTC6101AHS5#TRPBF uses a high-impedance feedback loop to force –IN to match +IN potential, enabling precise current-to-current conversion via external RIN. Its transconductance architecture (IOUT = VSENSE/RIN) eliminates common-mode voltage constraints on the output stage.
It supports unidirectional sensing with 500 mV full-scale input range, 140 kHz signal bandwidth at 200 µA load, and operates with VOUT up to 8 V (12–60 V supply) while maintaining 110–140 dB PSRR across 4–60 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 60 V - enables direct integration into 5 V, 12 V, 24 V, and 48 V industrial and automotive power rails without level-shifting. |
| Input Offset Voltage | ±85 µV max (A-grade, –40°C to 125°C) - allows use of small shunt resistors (e.g., 5 mΩ) while maintaining <1% error at 1 A load. |
| Response Time | 1 µs (to 2.5 V on 5 V output step) - supports fast overcurrent detection and real-time load warning in safety-critical systems. |
| PSRR | 118 dB min (6–60 V supply) - rejects supply ripple and noise, ensuring stable output under noisy DC bus conditions. |
| Supply Current | 250 µA typical at 12 V - minimizes self-heating and preserves efficiency in always-on battery monitoring circuits. |
| Input Bias Current | 170 nA max - reduces voltage error across high-value RIN resistors and enables accurate low-current measurement down to mA range. |
| Operating Temperature | –40°C to 125°C (H-grade) - qualified for under-hood automotive, industrial motor drives, and telecom rectifier applications. |
Pinout & Package
5-lead TSOT-23 (ThinSOT™) package with 1 mm profile, optimized for high-voltage spacing and thermal dissipation (θJA = 250°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: +IN | High-side sense input positive | Connected directly to load side of shunt resistor; Kelvin connection required for <0.5% accuracy at >5 A. |
| 2: –IN | High-side sense input negative | Driven to same potential as +IN by internal amplifier; tied to V+ via RIN to set transconductance gain. |
| 3: V+ | Positive supply input | Supplies operating current; connects to high-side rail; placement determines whether LTC6101AHS5#TRPBF current is included in measurement. |
| 4: V– | Negative supply / ground reference | Serves as output return and ground reference for VOUT; must be low-impedance path to avoid output error. |
| 5: OUT | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate VOUT = IOUT × ROUT. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable gain via RIN/ROUT | Enables flexible scaling (e.g., 20× to 100×) without changing IC; supports 250 mV to 50 mV full-scale VSENSE at 5 V output. |
| Low offset drift | ±1 µV/°C max ensures <0.1% gain error over full –40°C to 125°C range - critical for uncalibrated industrial sensors. |
| High PSRR | 118 dB rejection of supply noise prevents false triggers in switching power supply environments with >100 mV ripple. |
| Fast overload recovery | 1 µs step response with no phase reversal or latch-up - maintains control-loop stability during transient faults. |
| Low quiescent current | 250 µA at 12 V enables multi-year operation on coin-cell batteries in remote monitoring nodes. |

FAQ
What is the maximum input sense voltage supported by the LTC6101AHS5#TRPBF?
The LTC6101AHS5#TRPBF supports a maximum input sense voltage (VSENSE) of 500 mV, specified across its full operating temperature range. This full-scale limit ensures the internal amplifier remains linear and within offset specifications. Exceeding 500 mV may cause saturation or increased nonlinearity, especially at temperature extremes. The device's ±85 µV max offset enables accurate measurement down to ~170 µA with a 5 mΩ shunt at this full scale.
Can the LTC6101AHS5#TRPBF operate from a 5 V supply?
Yes, the LTC6101AHS5#TRPBF operates from 4 V to 60 V supply, fully supporting 5 V single-supply operation. At 5 V, it delivers 1 µs response time and maintains 110 dB PSRR. Output voltage swing is limited to 3 V (max) under 5 V supply per datasheet specifications, so ROUT must be selected accordingly - e.g., 10 kΩ with 300 µA IOUT yields 3 V full scale. Supply current is 220 µA typical at 5 V.
How does the LTC6101AHS5#TRPBF achieve high PSRR despite wide supply range?
The LTC6101AHS5#TRPBF achieves ≥118 dB PSRR through a proprietary high-gain, nested feedback architecture that actively rejects supply variations at the input stage. Its transconductance design inherently decouples output current from supply fluctuations, and internal biasing is regulated independently of V+. This is validated across 4–60 V supply with <0.1% gain variation - critical for accurate current measurement in noisy switcher-based rails where ripple exceeds 100 mV.
Is the LTC6101AHS5#TRPBF pin-compatible with other variants in the LTC6101 family?
Yes, all 5-lead TSOT-23 variants including LTC6101AHS5#TRPBF, LTC6101BHS5#TRPBF, and LTC6101CHS5#TRPBF share identical pinout (1:+IN, 2:–IN, 3:V+, 4:V–, 5:OUT) and footprint. Differences lie only in grade-specific parameters: offset (±85 µV vs ±150 µV vs ±400 µV), drift (±1 vs ±3 vs ±5 µV/°C), and temperature range certification. No PCB change is needed when upgrading within the same package.
What is the recommended layout practice for minimizing error in LTC6101AHS5#TRPBF measurements?
To minimize error, use Kelvin (4-wire) connections for +IN and –IN directly to the shunt resistor terminals, avoiding shared traces with load current. Route RIN close to the IC with short, symmetric traces; place ROUT between OUT and V– with low-inductance grounding. Keep high-current paths away from sense lines, and use solid ground plane beneath the IC. For 5 mΩ shunts, even 0.5 mΩ PCB trace resistance introduces 10% error at 10 A - hence Kelvin routing is mandatory.
