Product details
Overview
MAX40010HAUT+T from Maxim Integrated is a single-channel, high-side precision current-sense amplifier with 2.7V–76V input common-mode range, 100V/V fixed gain, ±25µV max input offset voltage (−40°C to +125°C), and 80kHz small-signal bandwidth-designed for accurate high-voltage current monitoring in base station power amplifiers, automotive battery management, and server backplane energy metering.
For engineers reviewing the MAX40010HAUT+T datasheet, MAX40010HAUT+T pinout, MAX40010HAUT+T application, or MAX40010HAUT+T equivalent, this page delivers verified package mapping (SOT23-6 U6SN+1), confirmed thermal specs (θJA = 74.6°C/W), real-world EMIR-filtered RF immunity, and precise gain-error behavior (0.7% max over full temperature range).
Technical Context
The MAX40010HAUT+T implements a high-voltage p-channel FET-based current mirror architecture that enables sensing independent of VDD, supporting operation with VCM up to 76V while VDD remains as low as 2.7V. Its internal gain-setting resistors (R1 = R2 = 25kΩ, RG1 = RG2 = 10kΩ, RF = 975kΩ) fix total gain at 100V/V per Table 1.
It features integrated EMI rejection filters on RS+/RS− inputs, achieves 140dB DC CMRR and 48dB AC CMRR at 200kHz, and delivers 2µs transient recovery time into 400Ω + 1nF load with 6pF ADC sampling capacitor-enabling direct interface with precision SAR ADCs in noisy telecom environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 100V/V - fixed ratio; outputs 2.5V for 25mV sense voltage, enabling high-resolution measurement with low-value shunts |
| Input Offset Voltage (max) | ±25µV (−40°C to +125°C) - ensures <0.1% error at 25mV full-scale input, critical for sub-ampere current sensing |
| Gain Error (max) | 0.7% (−40°C to +125°C) - guarantees consistent scaling across automotive and industrial temperature extremes |
| Small-Signal Bandwidth | 80kHz - supports fast transient detection in switching power supplies and motor control feedback loops |
| Input Common-Mode Range | 2.7V to 76V - allows direct high-side monitoring of 48V/60V telecom rails and 12V–48V automotive systems without level-shifting |
| Supply Voltage Range | 2.7V to 5.5V - compatible with standard 3.3V and 5V logic domains while maintaining full 76V CM capability |
| PSRR | 110–120dB - rejects supply noise to preserve accuracy in noisy DC-DC converter environments |
Pinout & Package
MAX40010HAUT+T is packaged in a 6-pin SOT23 (U6SN+1) with 0.95mm pitch, 2.9mm × 1.6mm footprint, and JEDEC-standard thermal performance (θJA = 74.6°C/W, derating 13.40mW/°C above +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connect | Internally unconnected; must be left floating or tied to GND per layout best practice-no functional impact |
| 2 (GND) | Ground Reference | Primary return path for internal bias and output stage; requires low-impedance Kelvin connection to system ground plane |
| 3 (VDD) | Supply Input | Power rail (2.7V–5.5V); bypass with 1µF ceramic capacitor within 2mm of pin to suppress high-frequency PSRR degradation |
| 4 (OUT) | Analog Output | Voltage output proportional to ISENSE × 100; drives 400Ω loads directly; stable with ≤200pF capacitive load without isolation resistor |
| 5 (RS+) | High-Side Sense Input (+) | Connects to power-rail side of shunt; includes integrated EMIR filter to attenuate RF interference from adjacent RF stages |
| 6 (RS−) | High-Side Sense Input (−) | Connects to load side of shunt; matched filtering and input bias current (65µA typ.) enable differential rejection of common-mode noise |
Key Features
| Feature | Design Value |
|---|---|
| EMI-Rejecting Inputs | Integrated passive RC filters on RS+/RS− suppress RF ingress from cellular/5G front-end circuits, validated by EMIRR vs. frequency plots |
| Ultra-Low Offset Drift | 130nV/°C TCVOS - maintains sub-µV/°C stability over −40°C to +125°C, reducing calibration burden in automotive ECUs |
| High-Voltage Independent Sensing | VCM up to 76V operates independently of VDD - enables monitoring of 48V battery stacks with 3.3V microcontroller supply |
| Fast Transient Recovery | 2µs settling to 0.1% after 2VP-P step - supports real-time current limiting in digitally controlled SMPS with >100kHz switching |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA240A1QDRQ1 | 50V/V fixed gain, ±10µV max offset (−40°C to +125°C), 4V/V to 500V/V programmable variants available; no integrated EMIR filter | Requires external RC filtering for RF immunity; better offset spec but lower gain limits resolution with ultra-low shunts | Select when tighter offset tolerance is prioritized over RF robustness and 100V/V scaling is not required |
| LT6106IMS5#TRPBF | 100V/V fixed gain, ±150µV max offset (−40°C to +85°C), 60kHz bandwidth, no EMIR filter, SOT23-5 (no NC pin) | Limited to +85°C ambient; higher offset degrades accuracy below 100mV sense voltage; lacks RF hardening for telecom use | Select for cost-sensitive industrial applications below 85°C with moderate RF exposure and relaxed accuracy requirements |

FAQ
What is the maximum input common-mode voltage supported by the MAX40010HAUT+T?
The MAX40010HAUT+T supports an input common-mode voltage range of 2.7V to 76V. This specification is guaranteed independent of supply voltage (VDD), enabling high-side sensing in 48V automotive systems and 60V telecom rails without level-shifting circuitry. Absolute maximum ratings allow RS+/RS− pins to tolerate up to +80V relative to GND, but functional operation is specified only up to +76V.
Does the MAX40010HAUT+T include built-in EMI rejection, and how is it implemented?
Yes, the MAX40010HAUT+T integrates passive EMIR (Electromagnetic Interference Rejection) filters on both RS+ and RS− inputs. These are on-chip RC networks designed to attenuate RF signals commonly found in base station and motor drive environments. The device's AC CMRR remains ≥48dB at 200kHz, and typical operating characteristics confirm effective suppression across 10kHz–1MHz bands without requiring external filtering components.
What is the guaranteed gain error of the MAX40010HAUT+T over its full operating temperature range?
The MAX40010HAUT+T has a guaranteed gain error of 0.7% maximum over the full −40°C to +125°C operating temperature range. At +25°C, gain error is tighter at 0.1% max. This specification is measured using two-point full-scale calibration (20% and 80% of full-scale sense voltage) and ensures predictable scaling for closed-loop control and energy metering applications across automotive and industrial environments.
Can the MAX40010HAUT+T drive an ADC input directly, and what load conditions ensure stability?
Yes, the MAX40010HAUT+T can drive ADC inputs directly. It remains stable with capacitive loads up to 200pF when no series isolation resistor is used, and up to 20nF when a 240Ω isolation resistor is added. For optimal performance with SAR ADCs, Maxim recommends a 500Ω series resistor and 14.7nF capacitor at the output-acting as both noise filter and charge reservoir during sample acquisition, as validated in Typical Operating Characteristic TOC20.
What package type and footprint does the MAX40010HAUT+T use, and is it RoHS-compliant?
The MAX40010HAUT+T uses a 6-pin SOT23 package (outline U6SN+1), measuring 2.9mm × 1.6mm with 0.95mm pin pitch. It is lead(Pb)-free and RoHS-compliant, indicated by the "+" suffix in the part number. Land pattern reference is 91-0175, and thermal performance is characterized per JEDEC JESD51-7 on a four-layer board (θJA = 74.6°C/W, derating 13.40mW/°C above +70°C).
