Product details
Overview
MAX11410AATI+T from Maxim Integrated is a 24-bit, multichannel, low-power delta-sigma ADC optimized for precision sensor measurement. It integrates a programmable gain amplifier (PGA) with gains from 1x to 128x, 10-channel analog multiplexer, matched excitation current sources (0.5µA–1600µA), and on-chip FIR digital filter delivering >90dB simultaneous 50Hz/60Hz rejection - enabling high-accuracy RTD, thermocouple, and resistive bridge measurements in portable instrumentation.
For engineers reviewing the MAX11410AATI+T datasheet, MAX11410AATI+T pinout, MAX11410AATI+T application, or MAX11410AATI+T equivalent, this device supports single-cycle settling in 16ms, on-demand self-calibration, SPI-compatible interface, and operates from -40°C to +125°C in a 28-pin 4mm × 4mm TQFN package - critical for space-constrained, battery-powered industrial and medical sensor systems.
Technical Context
The MAX11410AATI+T employs a third-order delta-sigma modulator with configurable FIR and sinc digital filters, enabling selectable data rates up to 1.9ksps and single-cycle settling mode. Its input path supports buffered, bypass, and PGA modes - each with distinct common-mode voltage constraints and dynamic range trade-offs.
Integrated features include dual differential reference inputs (REF0P/N, REF1P/N), three GPIOs (GPIO0/EXT_CLK, GPIO1, DOUT/INT#), programmable burnout currents for wire-break detection, and a 1.8V internal regulator (VDDREG) - all coordinated via 24-bit control registers accessible over SPI.
Key Specifications

| Data Rate | Up to 1.9ksps; supports real-time monitoring of slow-varying physical parameters (e.g., temperature, pressure) without oversampling penalty. |
| Power Line Rejection | >90dB simultaneous 50Hz/60Hz rejection; eliminates need for external notch filtering in AC-mains-noise environments. |
| INL | 3ppm typical; ensures linearity error <0.0003% FS across full scale - critical for calibration-critical metrology applications. |
| PGA Gains | 1x, 2x, 4x, 8x, 16x, 32x, 64x, 128x; allows optimal SNR matching to sensor output range without external amplification. |
| Excitation Current Range | 0.5µA to 1600µA in programmable steps; supports 2-/3-/4-wire RTD, strain gauge, and thermistor biasing with matched sourcing/sinking. |

Pinout & Package
MAX11410AATI+T is housed in a lead-free, RoHS-compliant 28-pin TQFN package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad. Pin functions are validated per Maxim's official datasheet Rev 0 (10/2020), Pin Configuration page 19.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN0–AIN9 | Analog Input Channels | 10 configurable single-ended or fully differential inputs; support mixed configurations (e.g., AIN0/AIN1 as diff pair, AIN2 as SE) for multi-sensor systems. |
| REF0P/REF0N, REF1P/REF1N | Differential Reference Inputs | Two dedicated + one shared reference pairs enable independent scaling per channel group or ratiometric measurement against sensor excitation. |
| GPIO0/EXT_CLK | Multi-function Terminal | Configurable as general-purpose output or external clock input; eliminates need for separate oscillator in timing-critical designs. |
| GPIO1 | General-Purpose Output | Drives external switches or status LEDs; reduces BOM count by replacing discrete logic or level-shifters. |
| DOUT/INT# | Serial Data Output / Interrupt | Open-drain interrupt output signals conversion completion or threshold violation; supports daisy-chain SPI readout in multi-ADC systems. |
| CS#, SCLK, DIN | SPI Interface Signals | Fully SPI-compatible (mode 0,0 and 1,1 supported); enables seamless integration with ARM Cortex-M, RISC-V, and legacy MCU platforms. |
| VDDREG, CAPREG | Internal 1.8V Regulator Outputs | Provide clean, regulated supply for internal logic; require external 1µF ceramic capacitor (CAPREG) for stability - no external LDO needed. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Excitation Current Sources | Matched 0.5µA/1µA/10µA sourcing and sinking enables precise 4-wire RTD biasing and open-circuit detection without external DACs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision delta-sigma ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS124S08IPWR | 24-bit, 4ksps, 12-channel ADC with integrated VREF and burnout current; lacks GPIOs and on-chip oscillator. | Better suited for fixed-rail industrial systems where external clock and reference are available; less flexible for portable designs. | Select when higher throughput (4ksps) and integrated reference outweigh need for GPIO control and self-contained timing. |
| AD7177-2BRUZ | 32-bit, 10ksps ADC with lower noise (270nV RMS) but no integrated excitation currents or multiplexer; requires external PGA. | Targeted at laboratory-grade metrology where ultimate resolution matters more than system integration or power efficiency. | Choose for applications demanding sub-1ppm INL and 200nV/√Hz noise floor - not for embedded sensor nodes with size/power constraints. |
Compared with ADS124S08IPWR and AD7177-2BRUZ, the MAX11410AATI+T uniquely combines integrated excitation, GPIOs, on-chip oscillator, and <1µA sleep mode - making it the only option that delivers full sensor-signal-chain integration in a 4mm × 4mm footprint for portable and battery-operated systems.

FAQ
What is the maximum sampling rate of the MAX11410AATI+T?
The MAX11410AATI+T supports a maximum data rate of 1.9ksps in standard mode. In single-cycle settling mode, it achieves full 24-bit resolution within 16ms - ideal for slowly varying sensor outputs like temperature or pressure. The actual achievable rate depends on selected digital filter configuration and line-frequency rejection settings (LINEF bits), as detailed in Table 9a–9d of the datasheet.
Does the MAX11410AATI+T support both single-ended and differential inputs?
Yes, the MAX11410AATI+T supports any combination of single-ended and fully differential inputs across its 10 AIN channels. For example, AIN0/AIN1 can be configured as a differential pair while AIN2–AIN4 operate as single-ended inputs - all under software control via MUX_CTRL0–MUX_CTRL2 registers. This flexibility simplifies hardware design for multi-sensor systems.
How does the MAX11410AATI+T handle sensor wire-break detection?
The MAX11410AATI+T implements wire-break detection using programmable burnout currents: a 0.5µA or 1µA current source/sink can be enabled on any analog input channel. When a break occurs, the resulting voltage shift at the input exceeds the configured threshold, triggering an interrupt via DOUT/INT#. This feature is validated in the "Burnout Currents" section (page 28) and requires no external circuitry.
Can the MAX11410AATI+T operate from a single 3.3V supply?
Yes, the MAX11410AATI+T operates with AVDD = 3.3V and VDDIO = 1.8V–3.3V. Its internal 1.8V regulator (VDDREG) powers core logic, eliminating need for external LDOs. All digital I/O tolerates 1.7V–3.6V, allowing direct connection to 3.3V or 1.8V microcontrollers. Absolute maximum ratings confirm AVDD-to-GND tolerance up to +3.6V.
What calibration capabilities does the MAX11410AATI+T provide?
The MAX11410AATI+T supports on-demand system offset/gain calibration and PGA-specific self-calibration via dedicated registers (CAL_START, SYS_OFF_A/B, SELF_GAIN_x). Calibration coefficients are stored in internal registers and applied automatically during conversion. Typical INL improves from ±10ppm to ±3ppm post-calibration - verified in Tables 5 and 6 of the datasheet.
