Product details
Overview
MAX1036MEKA+T from Maxim Integrated is a low-power, 8-bit, 4-channel analog-to-digital converter (ADC) with integrated track/hold, 4.096V internal reference, I²C-compatible 2-wire serial interface, and single-supply operation from 4.5V to 5.5V. It delivers 188ksps throughput with 350µA supply current and ±2 LSB total unadjusted error, targeting battery-powered sensor monitoring and system supervision in industrial and portable equipment.
For engineers reviewing the MAX1036MEKA+T datasheet, MAX1036MEKA+T pinout, MAX1036MEKA+T application, or MAX1036MEKA+T equivalent, key selection criteria include its 4-channel single-ended/pseudo-differential input architecture, software-configurable unipolar/bipolar mode, AutoShutdown™ power management, and guaranteed operation across –40°C to +85°C.
Technical Context
The MAX1036MEKA+T employs successive-approximation register (SAR) conversion with internal track/hold circuitry and a switched-capacitor DAC. Its analog front-end supports configurable single-ended or pseudo-differential inputs via CS[3:0] channel select and SGL/DIF bit control, with acquisition time dependent on source impedance and clock mode.
It operates exclusively in I²C 2-wire slave mode with fixed 7-bit address 1100100 (0x64), supporting Fast Mode (400kHz) and High-Speed Mode (1.7MHz). Internal clock generation enables autonomous conversion timing, while external clock mode allows precise synchronization with host controller timing constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit SAR ADC - delivers discrete digital output codes over full-scale range without interpolation. |
| Total Unadjusted Error | ±2 LSB - defines worst-case deviation between ideal and actual transfer function before calibration. |
| Sampling Rate | 188 ksps - maximum sustained conversion rate achievable in High-Speed I²C mode with external clock. |
| Supply Current | 350 µA at 188 ksps - enables ultra-low-power operation in energy-constrained embedded systems. |
| Input Channels | 4 single-ended or 2 pseudo-differential - provides flexible signal routing for multi-sensor monitoring with shared T/H circuitry. |
| Reference Voltage | 4.096 V internal - sets full-scale range for unipolar inputs; eliminates need for external precision reference in many applications. |
| Operating Voltage | 4.5 V to 5.5 V - compatible with standard 5V logic and industrial supply rails; excludes 2.7–3.6V operation. |
| Temperature Range | –40°C to +85°C - qualified for extended industrial environments without derating. |
Pinout & Package
The MAX1036MEKA+T is housed in an 8-pin SOT23 package (JEDEC MO-178AA), with 0.65mm pitch, 2.9mm × 1.6mm footprint, and exposed pad optional for thermal enhancement.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AIN0 | Analog input channel 0 - selectable as single-ended or '+' input in pseudo-differential mode. |
| 2 | AIN1 | Analog input channel 1 - shares same T/H capacitor and conversion path as AIN0–AIN3. |
| 3 | AIN2 | Analog input channel 2 - software-configurable polarity and input mode via setup/configuration registers. |
| 4 | AIN3/REF | Configurable terminal - functions as analog input 3 or reference voltage input/output depending on SEL[2:1] bits. |
| 5 | SCL | I²C serial clock input - controls data transfer timing; must be pulled high externally; supports 400kHz/1.7MHz modes. |
| 6 | SDA | I²C bidirectional data line - carries setup bytes, configuration data, and conversion results; requires pullup resistor. |
| 7 | GND | Analog/digital ground reference - common return for VDD, analog inputs, and reference circuitry; must be low-impedance. |
| 8 | VDD | Positive supply input - powers all internal circuitry including reference, T/H, and digital interface; bypass with 0.1µF capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| AutoShutdown™ power management | Reduces supply current to <1 µA between conversions - extends battery life in intermittent-sampling applications. |
| Integrated 4.096V reference | Eliminates external reference component and associated layout complexity - improves system-level accuracy and BOM simplicity. |
| Software-configurable input mode | Single-ended or pseudo-differential operation selected via SGL/DIF bit - enables flexible signal conditioning without hardware changes. |
| I²C Fast/High-Speed Mode support | Enables 400kHz or 1.7MHz bus rates - accommodates both resource-constrained microcontrollers and high-throughput data acquisition. |
| Internal track/hold with 2MHz bandwidth | Supports accurate digitization of transient signals up to 2MHz - suitable for undersampling and fast event capture. |
| Channel-scan FIFO capability | Automatically sequences through selected channels - reduces host CPU overhead during multi-channel monitoring tasks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit, I²C-interfaced, low-power ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 8-bit SAR ADC with SPI interface, 200ksps, 2.7–5.25V supply, no internal reference - requires external 2.5V reference. | Requires SPI host and external reference; lacks AutoShutdown™ and I²C compatibility. | Select when SPI interface is preferred and board already includes precision reference; not drop-in for I²C-based designs. |
| MAX11602AUT+T | 8-bit, 4-channel, I²C ADC with 1.8–3.6V supply, 2.048V internal reference, 100ksps max - incompatible supply voltage range. | Designed for low-voltage microcontroller systems; cannot operate from 4.5–5.5V rail used by MAX1036MEKA+T. | Choose for 3.3V-only systems where lower supply current (<150µA at 100ksps) and smaller footprint are prioritized. |
Compared with ADS7822U and MAX11602AUT+T, the MAX1036MEKA+T uniquely combines 4.5–5.5V operation, integrated 4.096V reference, I²C High-Speed Mode support, and AutoShutdown™ - making it optimal for industrial 5V-sensor nodes requiring minimal external components and robust power management.

FAQ
What is the maximum sampling rate supported by the MAX1036MEKA+T?
The MAX1036MEKA+T achieves a maximum sampling rate of 188 ksps when operating in I²C High-Speed Mode with an external clock. This rate is confirmed in the Electrical Characteristics table under "Throughput Rate" and requires proper bus timing compliance per Figures 1B and 2 in the datasheet. Internal clock mode limits throughput to 77 ksps.
Does the MAX1036MEKA+T require an external reference voltage?
No, the MAX1036MEKA+T does not require an external reference voltage because it integrates a precision 4.096V internal reference. This reference is factory-trimmed and specified over temperature (±120 ppm/°C TCREF). An external reference from 1V to VDD may be used instead, but doing so disables the internal reference and increases supply current slightly.
How many analog input channels does the MAX1036MEKA+T support?
The MAX1036MEKA+T supports four analog input channels (AIN0–AIN3), configurable as single-ended or pseudo-differential pairs. This is explicitly stated in the General Description and Ordering Information tables, and matches the 8-pin SOT23 package pinout where pins 1–4 are assigned to AIN0–AIN3/REF. The 12-channel variants (MAX1038/MAX1039) use a different 16-pin QSOP package.
What is the operating supply voltage range for the MAX1036MEKA+T?
The MAX1036MEKA+T operates from a single supply of 4.5V to 5.5V, as specified in the Electrical Characteristics table under "Supply Voltage (Note 10)" and confirmed in the Ordering Information section. It is not rated for 2.7–3.6V operation - that range applies only to the MAX1037/MAX1039 variants with 2.048V internal reference.
Can the MAX1036MEKA+T perform pseudo-differential measurements?
Yes, the MAX1036MEKA+T supports pseudo-differential measurements via the SGL/DIF bit in the configuration byte. In this mode, AIN3/REF serves as the '–' input while one of AIN0–AIN2 serves as the '+' input. The '–' input must remain stable within ±0.5 LSB relative to GND during conversion, and a 0.1µF capacitor to ground is recommended for stability.
