Analog Devices Inc./Maxim Integrated MAX11610EEE+T

Overview

MAX11610EEE+T from Maxim Integrated is a 10-bit, 12-channel, low-power analog-to-digital converter with integrated track/hold, 4.096V internal reference, I²C-compatible 2-wire interface, and operation from 4.5V to 5.5V supply. It delivers 94.4ksps throughput at 670µA, supports unipolar/bipolar and single-ended/differential input configurations, and targets precision sensor monitoring in battery-constrained industrial systems.

For engineers reviewing the MAX11610EEE+T datasheet, MAX11610EEE+T pinout, MAX11610EEE+T application, or MAX11610EEE+T equivalent, this page provides verified electrical specifications, QSOP-16 package mapping, I²C timing compliance (1.7MHz high-speed mode), channel-scan FIFO operation, and real-world design implications for system supervision and remote sensing.

Technical Context

The MAX11610EEE+T employs successive-approximation architecture with fully differential track-and-hold circuitry and a switched-capacitor DAC. Its analog front-end supports software-configurable 12 single-ended or 6 fully differential inputs, with acquisition time dependent on source impedance and clock mode (2/fSCL in external clock mode).

It integrates an internal 4.096V reference (±0.5% initial accuracy, 25ppm/°C drift) and accepts external references from 1V to VDD. The I²C interface operates in Fast Mode (400kHz) or High-Speed Mode (1.7MHz), with slave address 0110101 and configurable setup/configuration registers for scan mode, polarity, and input type.

Key Specifications

Pinout & Package

MAX11610EEE+T is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 1.0mm height), RoHS-compliant and rated for -40°C to +85°C operation. Pin layout follows standard I²C ADC conventions with dedicated analog ground, reference I/O, and channel-selectable analog inputs.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for demanding industrial, medical, and communications applications.

The MAX11606–MAX11611 family was engineered for space- and power-constrained systems needing multichannel data acquisition without external support components - specifically targeting battery-powered instrumentation and distributed sensor networks.

FAQ

What is the maximum sampling rate achievable with MAX11610EEE+T using its internal clock?

The MAX11610EEE+T achieves a maximum throughput rate of 53ksps when using its internal clock and SCAN[1:0] = 00 configuration. This is lower than the 94.4ksps possible with external clocking because the internal oscillator operates at 2.8MHz, limiting conversion cycle timing. For applications requiring >53ksps, external clock mode is mandatory - and the MAX11610EEE+T must be configured accordingly in the setup register.

Can MAX11610EEE+T operate with an external reference voltage, and what is the valid range?

Yes, MAX11610EEE+T supports external reference voltages from 1V to VDD (4.5V–5.5V). When using an external reference, the internal 4.096V reference is disabled, and the REF pin becomes a high-impedance input. Reference input current is 40µA at 94.4ksps, so the driving source must maintain stability under that load - typically achieved with a buffered reference IC or low-output-impedance LDO.

How does the AutoShutdown™ feature function in MAX11610EEE+T, and what is its impact on power consumption?

AutoShutdown™ automatically powers down the MAX11610EEE+T's analog core and reference between conversions when throughput falls below ~46ksps. This reduces supply current to <1µA in low-duty-cycle applications - for example, reading temperature every 10 seconds draws just 6µA average. The feature is transparent to firmware and requires no explicit command; it activates based solely on inter-conversion timing.

What are the absolute maximum ratings for analog input voltage on MAX11610EEE+T?

The MAX11610EEE+T analog inputs (AIN0–AIN11) tolerate voltages from (GND − 0.3V) to (VDD + 0.3V) due to internal ESD protection diodes. However, for accurate conversion, input voltage must remain within GND to VDD - exceeding those bounds by more than 50mV causes measurement errors or potential damage. With 4.096V internal reference, the usable unipolar range is 0–4.096V; bipolar mode extends effective range to ±2.048V differential.

Is MAX11610EEE+T pin-compatible with any higher-resolution variants in the same family?

No, MAX11610EEE+T is not pin-compatible with higher-resolution variants such as the MAX11612–MAX11617 (12-bit). Although both families use 16-pin QSOP packages, the pin assignments differ - notably, MAX11612–MAX11617 relocate SDA/SCL and add dedicated ALERT/CONVST pins. Migration requires PCB redesign and firmware updates to accommodate different register maps and timing requirements.
