Product details
Overview
MAX1136EUA+T from Maxim Integrated is a low-power, 10-bit, 4-channel analog-to-digital converter (ADC) with integrated track/hold, 4.096V internal reference, I²C-compatible 2-wire serial interface, and operation from 4.5V to 5.5V single supply. It delivers 94.4ksps throughput at 670µA, supports unipolar/bipolar and single-ended/differential input configurations, and targets battery-powered test equipment and solar-powered remote systems.
For engineers reviewing the MAX1136EUA+T datasheet, MAX1136EUA+T pinout, MAX1136EUA+T application, or MAX1136EUA+T equivalent, this page provides verified technical context, exact pin functions, real-world use cases, and validated alternative parts - all aligned to the official MAX1136–MAX1139 family specification and µMAX® package implementation.
Technical Context
The MAX1136EUA+T employs successive-approximation architecture with fully differential track/hold circuitry and an internal 2.8MHz clock. Its 4-channel analog multiplexer supports software-configurable single-ended (0–VREF) or differential (±VREF/2) inputs, with acquisition time of 800ns and full-linear bandwidth of 5.0MHz.
It uses a dedicated 2-wire I²C interface with programmable Fast Mode (400kHz) or High-Speed Mode (1.7MHz), factory-set slave address 0110100, and auto-shutdown reducing current to <0.5µA. Internal reference is fixed at 4.096V; external reference range is 1V to VDD.

| 4 | AIN3/REF | Configurable as analog input channel 3 or reference voltage output (4.096V) - requires 0.1µF decoupling when used as REF. |
| 5 | SCL | I²C clock input; accepts Fast Mode (400kHz) or High-Speed Mode (1.7MHz) timing per master control. |
| 6 | SDA | I²C bidirectional data line; open-drain, requires external pull-up; supports acknowledge/nack protocol. |
| 7 | GND | Analog and digital ground reference; must be connected to low-impedance system ground plane. |
| 8 | VDD | Positive supply input (4.5V–5.5V); bypass with 0.1µF ceramic capacitor directly to GND for noise immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit, multichannel, I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1137EUA+T | Same 8-pin µMAX package and pinout; 2.048V internal reference; operates from 2.7V–3.6V supply. | Optimized for 3.3V systems (e.g., ARM Cortex-M0+ microcontrollers) rather than 5V industrial rails. | Select MAX1137EUA+T when system VDD is 3.3V and lower reference headroom is acceptable. |
| ADS1114IDGSR | 16-bit resolution, single-channel, 2.048V reference, 3.3V-only supply (2.0–5.5V), no AutoShutdown, smaller 10-pin VSSOP package. | Lacks multichannel capability and programmable shutdown; higher resolution but lower throughput (860sps). | Choose ADS1114IDGSR only when 16-bit precision outweighs channel count, power, and speed requirements. |
Compared with MAX1137EUA+T, the MAX1136EUA+T offers higher reference voltage (4.096V vs. 2.048V) and 5V compatibility, making it preferable for legacy industrial interfaces; versus ADS1114IDGSR, it trades resolution for speed, channel count, and ultra-low-power operation - essential for portable multi-sensor systems.

FAQ
What is the operating supply voltage range for the MAX1136EUA+T?
The MAX1136EUA+T operates from a single supply of 4.5V to 5.5V. This range is strictly defined in the Absolute Maximum Ratings and Electrical Characteristics tables of the official datasheet. Operation outside this window may cause functional failure or permanent damage. The MAX1136EUA+T does not support 3.3V or dual-supply operation - for those, consider the MAX1137EUA+T variant instead.
Does the MAX1136EUA+T include an internal voltage reference, and what is its value?
Yes, the MAX1136EUA+T integrates a precision 4.096V internal reference with ±1% initial accuracy and 25ppm/°C temperature coefficient. This reference is factory-trimmed and powers both the ADC core and the AIN3/REF pin when configured as output. It eliminates the need for external reference components in most 5V-system applications, and its value is confirmed in the Selector Guide and Electrical Characteristics sections of the MAX1136–MAX1139 datasheet.
How many analog input channels does the MAX1136EUA+T support, and how are they configured?
The MAX1136EUA+T supports four analog input channels (AIN0–AIN3). These can be used in single-ended mode (four independent inputs referenced to GND) or fully differential mode (two differential pairs: AIN0–AIN1 and AIN2–AIN3), selected via the SGL/DIF bit in the configuration byte. Channel selection and input mode are software-configurable through the I²C interface - no hardware changes are needed to switch modes.
What I²C interface speeds does the MAX1136EUA+T support, and how is high-speed mode enabled?
The MAX1136EUA+T supports I²C Fast Mode (400kHz) and High-Speed Mode (1.7MHz). At power-up, it defaults to Fast Mode. To enable High-Speed Mode, the bus master must first send the HS-mode master code (0000 1XXX), receive a NOT-ACK, then issue a repeated START followed by the device's slave address (0110100). This sequence is mandatory - simply increasing clock frequency without protocol handshaking will result in communication failure.
What is the guaranteed temperature range for the MAX1136EUA+T, and is it suitable for industrial environments?
The MAX1136EUA+T is guaranteed over the extended industrial temperature range of -40°C to +85°C, as explicitly stated in the Ordering Information table and Absolute Maximum Ratings section. All key specifications - including INL (±1 LSB), supply current, reference stability, and conversion rate - are characterized across this full range. This makes the MAX1136EUA+T suitable for deployment in uncontrolled industrial enclosures, outdoor remote terminals, and medical devices requiring ambient resilience.
