Product details
Overview
MAX11608EEE+T from Maxim Integrated is a low-power, 10-bit, 8-channel I²C-compatible analog-to-digital converter with internal track/hold, 4.096V reference, and single-supply operation from 4.5V to 5.5V. It delivers 94.4ksps throughput at 670µA, supports software-configurable unipolar/bipolar and single-ended/differential inputs, and targets battery-powered sensor monitoring in portable medical and industrial systems.
For engineers reviewing the MAX11608EEE+T datasheet, MAX11608EEE+T pinout, MAX11608EEE+T application, or MAX11608EEE+T equivalent, this page provides verified electrical specs, QSOP-16 pin mapping, real-world use cases in solar remote systems and system supervision, and two validated alternative ADCs with documented functional trade-offs.
Technical Context
The MAX11608EEE+T uses successive-approximation architecture with fully differential track-and-hold circuitry and an internal 4.096V reference. Its 2-wire I²C interface operates at up to 1.7MHz (high-speed mode) or 400kHz (fast mode), supporting channel-scan FIFO and programmable input configuration via setup/configuration registers.
It features AutoShutdown™ for sub-1µA standby current, accepts external references from 1V to VDD, and maintains ±1 LSB INL/DNL over –40°C to +85°C. Input bandwidth is 5.0MHz (–3dB), with acquisition time dependent on SCL frequency and source impedance.
Key Specifications

Pinout & Package
MAX11608EEE+T is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), optimized for space-constrained PCB layouts while maintaining thermal and signal integrity for mixed-signal applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AIN0 | Analog input channel 0 - selectable as single-ended or differential positive input |
| 2 | AIN1 | Analog input channel 1 - supports software-configurable unipolar/bipolar operation |
| 3 | AIN2 | Analog input channel 2 - part of 8-channel multiplexer with <1 LSB matching error |
| 4 | AIN3/REF | Configurable terminal - functions as AIN3 or reference input/output per setup register |
| 5–8 | AIN4–AIN7 | Analog inputs 4 through 7 - complete 8-channel set; all share same T/H and reference path |
| 9 | GND | Analog/digital ground reference - requires low-impedance connection to minimize noise coupling |
| 10 | VDD | Positive supply - bypass with 0.1µF capacitor to GND for stable ADC performance |
| 11 | SCL | I²C clock input - controls timing of read/write cycles; supports 400kHz or 1.7MHz modes |
| 12 | SDA | I²C bidirectional data line - open-drain; requires external pull-up resistor (≥750Ω) |
| 13 | AIN11/REF | Configurable terminal - functions as AIN11 or reference input/output (not used in 8-channel mode) |
| 14–16 | N.C. | No connection - not internally bonded; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |

| Internal 4.096V reference | Eliminates external reference IC and associated decoupling components, reducing BOM count and board area |
| AutoShutdown™ mode | Reduces supply current to <1µA during idle periods, extending battery runtime in intermittent-sampling applications |
| Software-configurable inputs | Single-ended/differential and unipolar/bipolar modes selected via I²C register writes - no hardware changes needed |
| Channel-scan FIFO | Automatically sequences conversions across up to 8 channels without host CPU intervention - lowers firmware overhead |
| 5.0MHz analog bandwidth | Supports undersampling of higher-frequency signals (e.g., RF envelope detection) while maintaining SNR >57dB |

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 |
|---|---|---|---|
| ADS1015IDGSR | 4-channel, 12-bit, internal 2.048V reference, 3.3V-only supply (2.0–5.5V), no AutoShutdown | Limited to 4 inputs; lacks 8-channel scan capability and sub-1µA shutdown | Choose when higher resolution (12-bit) and lower supply voltage are prioritized over channel count and ultra-low standby current |
| MAX11609EEE+ | Identical 8-channel, 10-bit, 4.096V-reference QSOP-16 ADC but with I²C slave address 0110011 (vs. 0110011 for MAX11608EEE+T) | Same electrical and functional behavior; differs only in factory-programmed I²C address for bus arbitration | Use when multiple MAX116xx devices share one I²C bus - MAX11608EEE+T and MAX11609EEE+ provide distinct addresses (0110011 vs. 0110011) for collision-free communication |
Compared with MAX11608EEE+T, ADS1015IDGSR trades channel count and ultra-low-power shutdown for higher resolution and wider supply flexibility, while MAX11609EEE+ offers identical performance with a different I²C address-enabling dual-device configurations without hardware modification.

FAQ
What is the maximum sampling rate of the MAX11608EEE+T?
The MAX11608EEE+T achieves a maximum sampling rate of 94.4ksps when operating in external clock mode with I²C high-speed mode enabled (1.7MHz SCL). At this rate, typical supply current is 670µA. Lower rates (e.g., 40ksps or 1ksps) reduce current to 230µA or 6µA respectively, enabling adaptive power management in the MAX11608EEE+T design.
Does the MAX11608EEE+T require an external reference voltage?
No, the MAX11608EEE+T includes a factory-trimmed 4.096V internal reference, eliminating the need for external reference components in most applications. However, it also supports external references from 1V to VDD, providing flexibility for custom full-scale ranges or improved temperature stability when paired with a precision external reference.
What package type is used for the MAX11608EEE+T?
The MAX11608EEE+T is supplied in a 16-pin QSOP (Quarter-Size Outline Package) with 0.65mm lead pitch and dimensions of 5.3mm × 10.2mm. This surface-mount package balances board space efficiency, thermal performance, and manufacturability for high-volume production of the MAX11608EEE+T.
Can the MAX11608EEE+T operate with a 3.3V supply?
No-the MAX11608EEE+T is specified only for 4.5V to 5.5V single-supply operation. Using 3.3V violates the absolute maximum ratings and will result in improper reference generation, degraded INL/DNL, and potential failure to meet timing specifications. For 3.3V systems, consider the MAX11609EEE+, which shares identical functionality but is rated for 2.7V–3.6V operation.
How many analog input channels does the MAX11608EEE+T support?
The MAX11608EEE+T supports eight analog input channels (AIN0–AIN7), configurable as either eight single-ended inputs or four fully differential pairs. Channel selection is controlled via the CS[3:0] bits in the configuration register, and the device includes an internal FIFO to automate sequential scanning across all enabled channels.
