Product details
Overview
LTC6101CCS5#TRPBF from Analog Devices is a high-voltage, high-side current sense amplifier in 5-lead TSOT-23 package, delivering 1 µs step response, ±400 µV max input offset voltage, and operation from 4 V to 60 V supply. It converts shunt voltage into ground-referenced output current for precision load monitoring in automotive power rails and industrial DC supplies.
For engineers reviewing the LTC6101CCS5#TRPBF datasheet, LTC6101CCS5#TRPBF pinout, LTC6101CCS5#TRPBF application, or LTC6101CCS5#TRPBF equivalent, key selection criteria include its 500 mV full-scale sense voltage, 118 dB PSRR, 250 µA supply current at 12 V, and compatibility with Kelvin-connected shunts for <1% measurement error under high-current conditions.
Technical Context
The LTC6101CCS5#TRPBF uses a feedback-controlled transconductance architecture: its internal amplifier forces –IN to match +IN potential, enabling precise current sourcing (IOUT = VSENSE/RIN) independent of common-mode voltage up to 60 V. Gain is set externally via RIN and ROUT, supporting configurable output voltage scaling (e.g., 50×, 100×).
It operates in single-supply mode with V– tied to ground, supports input sense voltages up to 500 mV, and maintains 1 µs response time across its full 4 V–60 V supply range. Its low 170 nA max input bias current minimizes error when using high-value RIN resistors for microamp-level resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 60 V - enables direct monitoring of 12 V, 24 V, and 48 V industrial and automotive bus rails without level-shifting. |
| Input Offset Voltage (Max) | ±400 µV - limits minimum resolvable sense voltage to ~4 mV with 100 Ω RIN, supporting accurate 10 mA detection across 500 mΩ shunts. |
| Step Response Time | 1 µs - ensures timely detection of overcurrent events for fast-acting protection circuits in motor drives and power supplies. |
| PSRR | 118 dB min - rejects supply ripple and noise, preserving accuracy even on noisy battery or rectified AC lines. |
| Supply Current | 250 µA at 12 V - reduces self-heating and enables use in always-on battery-powered systems with multi-year runtime. |
| Input Sense Voltage Full Scale | 500 mV - allows use of low-value, low-power shunts (e.g., 10 mΩ @ 50 A) while maintaining >70 dB dynamic range. |
| Operating Temperature | 0°C to 70°C (specified) - validated for commercial-grade embedded power management in non-extended-environment applications. |
Pinout & Package
Package: 5-lead TSOT-23 (ThinSOT™), 1 mm profile, HV-optimized creepage/clearance spacing for high-side sensing up to 60 V.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: +IN | High-side sense input (non-inverting) | Connected directly to load-side of shunt resistor; forms Kelvin sense node for minimal trace-resistance error. |
| 2: –IN | High-side sense input (inverting) | Driven to same potential as +IN by internal amplifier; connected to supply-side of shunt via RIN to set transconductance gain. |
| 3: V+ | Positive supply input | Draws 250 µA supply current; must be decoupled near device; connects to high-side rail being monitored. |
| 4: V– | Negative supply / ground reference | Tied to system ground; defines output voltage reference and sinks output current through ROUT. |
| 5: OUT | Current output terminal | Sources IOUT = VSENSE/RIN; requires external ROUT to ground to generate analog voltage output (e.g., 5 kΩ → 5 V per 100 mV sense). |
Key Features
| Feature | Design Value |
|---|---|
| Configurable gain via two external resistors | Enables precise scaling (e.g., 20× to 100×) without redesigning amplifier core-supports flexible shunt sizing and ADC input range matching. |
| 1 µs fast step response | Meets real-time overcurrent shutdown requirements in switched-mode power supplies and motor controllers with <1 µs fault latency. |
| 118 dB PSRR | Maintains <0.001% gain error despite 1 Vpp supply ripple-critical for stable readings on unregulated battery or rectifier outputs. |
| Low 170 nA max input bias current | Reduces offset error contribution to <0.17 µV per kΩ of RIN, enabling high-gain configurations without significant bias-induced drift. |
| 500 mV full-scale sense voltage | Permits use of ultra-low-value shunts (e.g., 5 mΩ @ 100 A), minimizing power loss (<500 mW) and thermal derating concerns. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4080TASA+ | Fixed 20×, 50×, or 100× gain; no external RIN/ROUT configuration; 2.7 V–76 V supply; 120 µV max offset (A grade) | Requires no external gain-setting resistors but lacks flexibility for custom scaling; better offset but narrower temperature spec (–40°C to +125°C vs. LTC6101C's 0°C–70°C) | Select MAX4080TASA+ when fixed gain simplifies layout and tighter offset is critical; avoid if variable gain or commercial-temp-only qualification is required. |
| INA240A1DGNR | Zero-drift architecture; 2.5 µV/°C drift; 120 V common-mode range; 4 V–80 V supply; 100 kHz bandwidth | Superior DC accuracy and drift performance, but slower response (2.5 µs) and higher quiescent current (2.4 mA); requires separate VREF for bipolar output | Select INA240A1DGNR for precision DC measurements where long-term stability outweighs speed; avoid for fast transient detection or ultra-low-power designs. |
Compared with MAX4080TASA+ and INA240A1DGNR, the LTC6101CCS5#TRPBF offers uniquely configurable gain with minimal external components, best-in-class 1 µs response for protection-critical systems, and lowest quiescent current-making it optimal for cost-sensitive, speed- and power-constrained high-side sensing.

FAQ
What is the maximum common-mode voltage the LTC6101CCS5#TRPBF can measure?
The LTC6101CCS5#TRPBF supports high-side sensing with a supply voltage range of 4 V to 60 V, and its inputs operate up to V+ – 4 V. When powered from a 60 V rail, it reliably measures shunt voltages with up to 56 V common-mode potential. Absolute maximum rating is 70 V total supply voltage, but operation beyond 60 V violates specified performance limits.
Can the LTC6101CCS5#TRPBF be used with a single 5 V supply?
Yes, the LTC6101CCS5#TRPBF functions correctly with a 5 V supply. At 5 V, it delivers 1 µs step response, maintains 118 dB PSRR, and draws only 220 µA supply current. Input sense voltage remains limited to 500 mV full scale, and output swing is constrained by VOUT(max) = 3 V (per datasheet, VS = 5 V, VSENSE = 330 mV).
How does the LTC6101CCS5#TRPBF achieve ground-referenced output from a high-side shunt?
The LTC6101CCS5#TRPBF uses an internal transconductance amplifier that forces –IN to match +IN, causing current IOUT = VSENSE/RIN to flow from OUT to V– (ground). With ROUT tied between OUT and V–, VOUT = IOUT × ROUT becomes a ground-referenced voltage proportional to shunt voltage-enabling direct interface to ADCs or comparators without isolation.
What is the minimum detectable load current using the LTC6101CCS5#TRPBF?
With ±400 µV max input offset and 500 mV full-scale sense range, the LTC6101CCS5#TRPBF resolves down to ~0.8 mV sense voltage before offset dominates. Using a 100 mΩ shunt, this corresponds to 8 mA minimum detectable current. With a 10 mΩ shunt and 100× gain (RIN = 100 Ω, ROUT = 10 kΩ), resolution improves to 0.8 mA at full scale.
Does the LTC6101CCS5#TRPBF require Kelvin connections for accurate measurement?
Yes-Kelvin (4-wire) connection of +IN and –IN to opposite ends of the shunt resistor is strongly recommended. Trace resistance as low as 0.5 mΩ introduces 1% error at 100 mV sense voltage and 2 A load. The LTC6101CCS5#TRPBF's low offset and high PSRR make it especially sensitive to such parasitic resistances, and Kelvin routing preserves sub-1% accuracy in production layouts.
