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 precision sensing in space-constrained battery-powered systems.
For engineers reviewing the MAX1036MEKA-T datasheet, MAX1036MEKA-T pinout, MAX1036MEKA-T application, or MAX1036MEKA-T equivalent, this page provides verified electrical parameters, confirmed SOT23-8 package mapping, validated I²C timing compliance (Fast Mode and High-Speed Mode), and real-world use context for portable medical instrumentation and solar-powered remote monitoring.
Technical Context
The MAX1036MEKA-T implements successive-approximation ADC architecture with on-chip track/hold capacitor and switched-capacitor DAC. It supports software-configurable unipolar single-ended input mode across four analog channels (AIN0–AIN3), with full-scale range set by its factory-trimmed 4.096V internal reference or an external 1V–VDD reference.
Its I²C interface operates at up to 1.7MHz in High-Speed Mode and includes auto-address recognition (slave address 1100100), internal FIFO with channel-scan capability, and AutoShutdown™ that reduces quiescent current to 1µA between conversions - all while maintaining guaranteed performance over –40°C to +85°C.
Key Specifications

Pinout & Package
MAX1036MEKA-T is housed in an 8-pin SOT23 package (JEDEC MO-178AA), optimized for PCB area efficiency and thermal performance in compact portable designs. The package requires standard reflow soldering and GND-plane thermal relief per Maxim's layout guidelines.
| Pin | Circuit Role | Design Meaning |
|---|---|---|

| 2 | AIN1 | Analog input channel 1 - software-selectable via CS[3:0] bits in configuration register. |
| 3 | AIN2 | Analog input channel 2 - supports pseudo-differential mode when paired with AIN3/REF. |
| 4 | AIN3/REF | Configurable terminal - functions as AIN3 in single-ended mode or reference input/output in external REF mode. |
| 5 | SCL | I²C clock input - controls data transfer timing; supports Fast Mode (400 kHz) and High-Speed Mode (1.7 MHz). |
| 6 | SDA | I²C bidirectional data line - carries setup/configuration bytes and conversion results. |
| 7 | GND | Analog/digital ground reference - must be connected to low-impedance system ground plane. |
| 8 | VDD | Positive supply input - requires 0.1 µF ceramic bypass capacitor to GND for noise suppression. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit, I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 8-bit, 200 ksps, SPI interface, 2.7–5.25 V supply, no internal reference - requires external 2.5V ref. | Requires SPI host and external reference; higher speed but less integration than MAX1036MEKA-T. | Select when SPI is preferred and board space allows external reference; not drop-in for I²C systems. |
| MCP3021A0T-E/OT | 10-bit, 100 ksps, I²C interface, 2.7–5.5 V, internal 2.048V reference - higher resolution but lower speed and different ref voltage. | Delivers finer quantization but cannot match 188 ksps; 2.048V ref limits full-scale range vs. 4.096V. | Choose for improved resolution where speed <100 ksps suffices and 2.048V scaling aligns with system design. |
Compared with ADS7822U and MCP3021A0T-E/OT, MAX1036MEKA-T uniquely combines 188 ksps I²C throughput, integrated 4.096V reference, and 4-channel scan capability in SOT23-8 - making it optimal for compact, battery-efficient 5V systems requiring calibrated multi-sensor digitization without external support components.

FAQ
What is the internal reference voltage of the MAX1036MEKA-T?
The MAX1036MEKA-T features a factory-trimmed 4.096V internal reference with ±0.5% initial accuracy and 120 ppm/°C temperature coefficient. This reference sets the full-scale input range for unipolar single-ended operation and can be overridden by an external 1V–VDD reference applied to the AIN3/REF pin. The 4.096V value enables precise 1mV-per-LSB scaling when used with the 8-bit output.
Does the MAX1036MEKA-T support pseudo-differential input mode?
Yes, the MAX1036MEKA-T supports pseudo-differential input mode via software configuration (SGL/DIF = 0 in the configuration byte). In this mode, AIN2 serves as the '+' input and AIN3/REF as the '–' input. The '–' input must remain stable within ±0.5 LSB relative to GND during conversion. This mode provides 75 dB channel-to-channel crosstalk rejection and improves noise immunity in noisy environments.
What is the maximum I²C clock frequency supported by the MAX1036MEKA-T?
The MAX1036MEKA-T supports I²C Fast Mode up to 400 kHz and High-Speed Mode up to 1.7 MHz. High-Speed Mode is required to achieve the full 188 ksps sampling rate. Entry into HS-mode is triggered by the master sending the HS-mode master code (00001XXX), followed by a repeated START and slave address. Timing parameters including tHIGH, tLOW, and tR/tF are fully specified in the datasheet for both modes.
How does AutoShutdown™ operate in the MAX1036MEKA-T?
AutoShutdown™ automatically powers down the MAX1036MEKA-T between conversions when configured for low-throughput operation. In this state, supply current drops to ≤1 µA. The feature activates based on I²C bus activity and internal timing - no external control signal is needed. It resumes full operation upon receipt of a new conversion command, with minimal wake-up latency. This behavior is inherent to the MAX1036MEKA-T silicon and requires no firmware intervention.
What package type is used for the MAX1036MEKA-T?
The MAX1036MEKA-T is packaged in an 8-pin SOT23 (JEDEC MO-178AA) with gull-wing leads. This surface-mount package measures 2.9 mm × 1.6 mm × 1.1 mm and is compatible with standard reflow profiles. Pin 1 is marked by a dot or notch, and the top mark "AEKO" identifies the MAX1036MEKA-T variant per Maxim's ordering guide.
