Product details
Overview
MAX11200EEE+ from Maxim Integrated is a 24-bit, single-channel, ultra-low-power delta-sigma ADC optimized for high-dynamic-range sensor measurement in battery-powered and 4–20mA loop applications. It delivers 24.0-bit ENOB at 5sps, <300µA total active current, and >100dB 50Hz/60Hz line-noise rejection using its internal oscillator and SINC4 digital filter.
For engineers reviewing the MAX11200EEE+ datasheet, MAX11200EEE+ pinout, MAX11200EEE+ application, or MAX11200EEE+ equivalent, key selection criteria include its 16-pin QSOP package, GPIO-controlled external multiplexer support, buffered/unbuffered analog/reference inputs, and self-calibration capability for offset/gain correction without external components.
Technical Context
The MAX11200EEE+ employs a third-order delta-sigma modulator with SINC4 digital filtering, enabling software-selectable data rates from 0.833sps to 480sps in continuous or single-cycle mode. Its internal oscillator operates at 2.048MHz (LINEF=1) or 2.4576MHz (LINEF=0), directly determining notch frequencies for 50Hz or 60Hz rejection.
It supports fully differential analog inputs (AINP/AINN) and reference inputs (REFP/REFN), with optional signal and reference buffers reducing input current to 20nA/30nA and enabling use with high-impedance transducers. Calibration is performed via SPI commands for on-demand offset/gain self-calibration or system-level zero/full-scale calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24-bit delta-sigma architecture with 24.0-bit ENOB at 5sps - enables precise low-frequency sensor digitization without oversampling penalties. |
| Power Consumption | <300µA total active current (AVDD + DVDD) - extends battery life in portable instrumentation and remote sensors. |
| Line-Noise Rejection | >100dB rejection at 50Hz/60Hz (min) - eliminates mains interference in industrial temperature/pressure monitoring. |
| Input Structure | Fully differential AINP/AINN and REFP/REFN with programmable buffers - isolates switched-capacitor sampling network from high-Z sources. |
| Data Interface | SPI-compatible serial interface with RDY/DOUT dual-function pin - simplifies microcontroller integration and reduces I/O count. |
| Operating Range | −40°C to +85°C, AVDD = 2.7V–3.6V, DVDD = 1.7V–3.6V - supports deployment in harsh industrial environments. |
| Calibration | On-chip offset/gain self-calibration and system calibration registers - eliminates need for external trim components and improves long-term accuracy. |
Pinout & Package
MAX11200EEE+ is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), suitable for space-constrained PCB layouts in portable and loop-powered systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 16 | GPIO1–GPIO4 | Register-controllable digital I/Os for driving external analog switches or muxes - enables multi-channel sensor scanning without additional logic. |
| 4 | GND | Common ground reference for analog and digital circuitry - requires star grounding to maintain noise-free reference integrity. |
| 5, 6 | REFP / REFN | Differential reference voltage inputs - accept buffered/unbuffered external references up to AVDD; common-mode range: 0V to AVDD. |
| 7, 8 | AINN / AINP | Fully differential analog input pair - supports unipolar (0 to VREF) or bipolar (±VREF) ranges; input buffers reduce dynamic loading on high-Z sensors. |
| 9, 10 | AVDD / DVDD | Separate analog (2.7–3.6V) and digital (1.7–3.6V) supplies - allows independent power domain optimization and noise isolation. |
| 11–14 | CS / DIN / RDY/DOUT / SCLK | Standard SPI interface pins with RDY flag - RDY/DOUT asserts low when conversion result is ready, enabling interrupt-driven reads. |
| 15 | CLK | External clock input (2.048/2.25275/2.4576MHz) - overrides internal oscillator for precise timing control or simultaneous 50/60Hz rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power operation | 235–300µA total active current and <0.4µA sleep current - enables multi-year battery life in wireless sensor nodes. |
| Integrated 50/60Hz rejection | SINC4 filter with configurable notch placement - achieves >100dB rejection without external notch filters or DSP post-processing. |
| Configurable input buffering | Independent SIGBUF/REFBUF control - reduces analog input current from 1.4FA/V to 20nA and reference current from 2.1FA/V to 30nA. |
| Self- and system-calibration | On-chip offset/gain registers with SPI-accessible CAL1/CAL0 commands - corrects drift and gain error without external calibration hardware. |
| GPIO-controlled multiplexing | Four SPI-configurable GPIOs - directly drive MAX313 or similar quad SPST switches for sequential multi-sensor acquisition. |

FAQ
What is the maximum data rate supported by the MAX11200EEE+ in single-cycle mode?
The MAX11200EEE+ supports up to 120sps in single-cycle conversion mode when LINEF = 0 (2.4576MHz internal oscillator) and up to 100sps when LINEF = 1 (2.048MHz oscillator). This mode provides zero-latency output with no pipeline delay, ideal for real-time threshold detection in sensor interfaces.
Does the MAX11200EEE+ include an internal oscillator, and can it be bypassed?
Yes, the MAX11200EEE+ features a factory-trimmed internal oscillator operating at either 2.048MHz or 2.4576MHz, selectable via the LINEF bit. It can be bypassed by applying an external clock signal (e.g., 2.25275MHz) to the CLK pin to achieve simultaneous 50Hz/60Hz rejection - the internal oscillator is disabled when EXTCLK = 1.
How does the MAX11200EEE+ handle high-impedance sensor sources like RTDs or thermistors?
The MAX11200EEE+ supports optional input buffers on both AINP/AINN and REFP/REFN, reducing dynamic input current from ~1.4FA/V to a constant 20nA (signal) or 30nA (reference). This prevents gain/linearity degradation when interfacing with high-Z sources, preserving 24-bit ENOB performance without external op-amp buffering.
Can the MAX11200EEE+ perform calibration without external equipment?
Yes, the MAX11200EEE+ supports on-chip self-calibration (offset and gain) and system-level calibration via SPI commands. Self-calibration requires no external signals and completes in 200ms; system calibration applies user-provided zero/full-scale inputs to correct for source resistance and board-level errors - all using internal registers.
What is the function of the GPIO pins on the MAX11200EEE+, and how are they controlled?
The MAX11200EEE+ provides four GPIOs (GPIO1–GPIO4) configured and driven via the CTRL2 register over SPI. They serve as general-purpose outputs to control external analog switches (e.g., MAX313), enabling sequential multi-sensor acquisition without MCU GPIO overhead - each pin is individually direction- and state-programmable.
