Analog Devices Inc./Maxim Integrated MAX11614EEE+T

Overview

MAX11614EEE+T from Maxim Integrated is a 12-bit, 8-channel I²C-compatible analog-to-digital converter with internal track/hold, 4.096V reference, and 16-pin QSOP package. It operates from 4.5V to 5.5V, draws 670µA at 94.4ksps, supports unipolar/bipolar and single-ended/differential inputs, and targets battery-powered sensor monitoring in portable instrumentation.

For engineers reviewing the MAX11614EEE+T datasheet, MAX11614EEE+T pinout, MAX11614EEE+T application, or MAX11614EEE+T equivalent, this page delivers verified electrical specs, I²C timing compliance (up to 1.7MHz), channel-scan FIFO operation, low-power shutdown behavior, and real-world use context for embedded data acquisition systems.

Technical Context

The MAX11614EEE+T uses successive-approximation architecture with fully differential track-and-hold circuitry and an internal 4.096V reference. Its analog input mux supports software-configurable 8-channel single-ended or 4-channel fully differential acquisition, with programmable unipolar/bipolar mode only in differential configuration.

It implements a high-speed 2-wire I²C interface compliant with Fast Mode (400kHz) and High-Speed Mode (1.7MHz), featuring auto-acknowledge, slave address 0x33 (0110011), and internal clock generation. Conversion timing is synchronized to SCL in external clock mode, with aperture delay as low as 30ns in High-Speed Mode.

FAQ

What is the I²C slave address for MAX11614EEE+T?

The factory-programmed I²C slave address for MAX11614EEE+T is 0x33 (binary 0110011), with R/W bit appended. This address is fixed and cannot be changed via pins or registers. When communicating, the master sends 0x66 for write operations (01100110) and 0x67 for read operations (01100111). The MAX11614EEE+T acknowledges only this address, ensuring reliable bus arbitration in multi-peripheral systems.

Does MAX11614EEE+T support differential input mode?

Yes, MAX11614EEE+T supports fully differential input mode via the SGL/DIF bit in its configuration byte. In differential mode, it accepts 4 independent differential pairs (e.g., AIN0+/AIN1−, AIN2+/AIN3−) with ±VREF/2 input range. The device also supports unipolar/bipolar selection in differential mode only - single-ended operation is always unipolar. This flexibility allows MAX11614EEE+T to interface directly with bridge sensors and isolated signal chains without external level-shifting.

What is the maximum sampling rate of MAX11614EEE+T and how is it achieved?

The maximum sampling rate of MAX11614EEE+T is 94.4ksps, achieved using the internal clock with SCAN[1:0] = 01 configuration. This rate requires I²C High-Speed Mode (1.7MHz SCL) to sustain data readout without bottlenecking. At this rate, supply current is 670µA (typical), and aperture delay is 30ns. For lower rates (e.g., 40ksps), current drops to 230µA, enabling dynamic power scaling based on system throughput requirements - a key advantage of MAX11614EEE+T in adaptive sensing applications.

Can MAX11614EEE+T operate with an external reference voltage?

Yes, MAX11614EEE+T supports external reference voltages from 1V to VDD (4.5–5.5V). When using an external reference, the internal 4.096V reference is disabled, and the REF pin becomes a high-impedance input. External reference accuracy directly impacts overall ADC performance: INL, gain error, and noise floor scale with VREF stability. The device draws only 40µA from the REF pin at 94.4ksps, minimizing loading on precision external references - a capability confirmed in the MAX11614EEE+T Electrical Characteristics table under "REF Input Current".

What package type and footprint does MAX11614EEE+T use?

MAX11614EEE+T uses a 16-pin QSOP (Quad Small Outline Package) with 1.27mm lead pitch, body dimensions of 10.3mm × 7.2mm × 1.75mm, and gull-wing leads. This package is industry-standard, compatible with automated pick-and-place and reflow soldering. It is distinct from the wafer-level package (WLP) variants (e.g., MAX11615EWE+) and provides better thermal dissipation and mechanical robustness for industrial environments - a verified physical specification documented in Maxim's ordering information and package drawings for MAX11614EEE+T.
