Analog Devices Inc./Maxim Integrated MAX40010TAUT+

Overview

MAX40010TAUT+ from Maxim Integrated is a single-channel, high-side precision current-sense amplifier with 20V/V fixed gain, 2.7V to 76V input common-mode voltage range, ±25µV max input offset voltage over -40°C to +125°C, 0.7% max gain error across full temperature range, and 80kHz small-signal bandwidth - deployed in base station power amplifier current monitoring where high-voltage sensing and low shunt loss are critical.

For engineers reviewing the MAX40010TAUT+ datasheet, MAX40010TAUT+ pinout, MAX40010TAUT+ application, or MAX40010TAUT+ equivalent, this page delivers verified package mapping (SOT23-6 U6SN+1), terminal roles, thermal resistance (θJA = 74.60°C/W), EMIR-filtered inputs, and real-world selection guidance against comparable high-voltage sense amplifiers.

Technical Context

The MAX40010TAUT+ implements a high-voltage p-channel FET–based current mirror architecture that enables input common-mode independence from VDD, allowing accurate sensing at VCM up to 76V even when VDD is as low as 2.7V. Its internal gain-setting resistors (R1 = 25kΩ, RG1 = 10kΩ, RF = 175kΩ) fix total gain at 20V/V per Table 1.

EMI rejection is achieved via integrated passive RC filters on RS+ and RS− inputs, validated by AC CMRR ≥48dB at 200kHz and AC PSRR ≥40dB at same frequency. Output stage features rail-to-rail swing (VOH = VDD − 16mV, VOL = 15mV @ 500µA) and 2µs transient recovery into 400Ω + 1nF + 6pF ADC sampling capacitor.

FAQ

What is the guaranteed input common-mode voltage range for MAX40010TAUT+?

The MAX40010TAUT+ guarantees an input common-mode voltage range of 2.7V to 76V across its full operating temperature range (-40°C to +125°C). This specification is independent of VDD and enables reliable sensing in high-voltage systems such as 48V server rails and 76V telecom power amplifiers, even when supply voltage is as low as 2.7V. The device remains functional up to 80V common-mode stress per Absolute Maximum Ratings.

Does MAX40010TAUT+ include built-in EMI rejection circuitry?

Yes, MAX40010TAUT+ integrates passive RC EMI rejection filters on both RS+ and RS− inputs. These filters provide ≥48dB AC CMRR at 200kHz and improve immunity to RF interference commonly found in base station and industrial motor drive environments. No external filtering components are required to meet EN 55022 Class B emissions limits when used per recommended layout guidelines.

What is the maximum gain error specification for MAX40010TAUT+ over temperature?

The MAX40010TAUT+ has a maximum gain error of 0.7% over the full operating temperature range of -40°C to +125°C. At +25°C, gain error is tighter at 0.1%, and it degrades to 0.5% at -40°C to +85°C. This performance is enabled by laser-trimmed internal resistors (R1, RG1, RF) and ensures predictable scaling from sense voltage to output across automotive and industrial thermal profiles.

Which package does MAX40010TAUT+ use, and what are its thermal characteristics?

MAX40010TAUT+ uses the 6-pin SOT23 package (U6SN+1 outline, 21-0058) with θJA = 74.60°C/W and θJC = 6.0°C/W. Its continuous power dissipation is rated at 13.40mW at +70°C ambient, derating linearly above that point. This package supports reflow soldering at +260°C (Pb-free) and provides sufficient thermal margin for ambient temperatures up to +85°C in typical PCB layouts with 2oz copper and thermal vias.

How does the output stage of MAX40010TAUT+ behave under load?

The MAX40010TAUT+ output stage delivers rail-to-rail swing: VOH = VDD − 16mV (sourcing 500µA) and VOL = 15mV (sinking 500µA). It drives 400Ω loads directly and settles to 0.1% of final value within 2µs when loaded with 400Ω + 1nF + 6pF (simulating ADC sampling capacitance). Output impedance is 0.1mΩ, minimizing loading effects on downstream signal chains.
