Product details
Overview
MAX11604EEE+T from Maxim Integrated is a low-power, 12-channel, 8-bit 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 188ksps throughput with 350µA supply current and supports software-configurable unipolar/bipolar and single-ended/pseudo-differential input modes for precision sensor monitoring in battery-constrained systems.
For engineers reviewing the MAX11604EEE+T datasheet, MAX11604EEE+T pinout, MAX11604EEE+T application, or MAX11604EEE+T equivalent, this page provides verified electrical parameters, package mapping to 16-pin QSOP, confirmed I²C timing compliance (up to 1.7MHz), real-world power consumption curves, and validated alternative part selection guidance - all specific to the MAX11604EEE+T variant.
Technical Context
The MAX11604EEE+T implements successive-approximation ADC architecture with on-chip track/hold capacitor and switched-capacitor DAC. Its 12-input multiplexer supports channel-scan mode via internal FIFO and accepts configuration through I²C setup/configuration bytes defining reference source (internal 4.096V or external 1V–VDD), clock source (internal 2.25MHz or external), and input mode (SGL/DIF, BIP/UNI).
It operates exclusively in 4.5V–5.5V supply range with ±1 LSB total unadjusted error (TUE), 75dB CMRR in pseudo-differential mode, and 2MHz full-power analog input bandwidth. Acquisition time is 588ns with internal clock and scales with external SCL frequency; aperture delay is 30ns in high-speed I²C mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - delivers 256 discrete output codes for basic sensor digitization without oversampling complexity. |
| Input Channels | 12 single-ended or 6 pseudo-differential - enables compact multi-sensor acquisition (e.g., temperature, voltage, current) without external MUX. |
| Internal Reference | 4.096V - provides stable full-scale range matching common microcontroller VREFs and simplifies layout by eliminating external reference IC. |
| Supply Range | 4.5V to 5.5V - compatible with standard 5V logic rails and industrial power supplies; excludes 2.7–3.6V variants. |
| Throughput Rate | 188ksps - supports real-time sampling of signals up to ~200kHz bandwidth (per Nyquist criterion) in high-speed monitoring. |
| Total Unadjusted Error | ±1 LSB - ensures monotonicity and <0.4% full-scale accuracy without calibration in cost-sensitive embedded applications. |
| I²C Interface Speed | Up to 1.7MHz (high-speed mode) - reduces conversion readout latency to <10µs per sample, critical for closed-loop control feedback. |
Pinout & Package
MAX11604EEE+T is housed in a 16-pin QSOP (Quad Small Outline Package) with 0.65mm lead pitch, rated for -40°C to +85°C operation and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | AIN11/REF | Configurable terminal: analog input channel 11 or reference input/output - requires 0.01µF decoupling when used as REF. |
| 2–10 | AIN0–AIN8 | Dedicated single-ended analog inputs - support pseudo-differential pairing (e.g., AIN0+/AIN1−) with software-selectable polarity. |
| 11–12 | AIN9, AIN10 | Additional analog inputs completing the 12-channel set - share same input structure and leakage specs (±0.01µA max). |
| 13 | SCL | I²C serial clock input - accepts 400kHz fast-mode or 1.7MHz high-speed-mode timing; requires external pull-up resistor. |
| 14 | SDA | I²C bidirectional data line - open-drain output; must be pulled high externally and supports ACK/NACK handshake. |
| 15 | GND | Analog/digital ground reference - separate AGND/DGND not implemented; requires low-impedance PCB return path. |
| 16 | VDD | Positive supply input - bypassed with 0.1µF ceramic capacitor to GND; powers internal reference, T/H, and digital core. |
Key Features
| Feature | Design Value |
|---|---|
| AutoShutdown™ between conversions | Reduces idle current to ≤1µA - extends battery life in intermittent-sampling applications like remote telemetry nodes. |
| Software-configurable input modes | Single-ended or pseudo-differential + unipolar/bipolar selection via I²C register - eliminates need for external signal conditioning circuitry. |
| Internal FIFO with channel-scan mode | Automates sequential conversion across all 12 channels - simplifies firmware by offloading timing-critical sequencing to hardware. |
| Low source impedance tolerance | Accurate sampling with ≤1.5kΩ source impedance - avoids mandatory op-amp buffering in most resistive sensor interfaces (e.g., RTDs, potentiometers). |
| Integrated 4.096V reference | 120ppm/°C tempco and ±0.5% initial accuracy - enables ratiometric measurements against system VDD without external reference drift compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-channel, 8-bit, I²C ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 12-bit resolution, SPI interface, 2.7–5.25V supply, no internal reference - requires external 2.5V ref and level-shifting for 5V systems. | Higher precision but incompatible interface and power domain - necessitates PCB redesign and firmware rewrite. | Select only if resolution >8-bit is mandatory and I²C is not required; verify SPI master compatibility and reference sourcing. |
| MAX11605EEE+ | Same 16-pin QSOP package and pinout, identical 12-channel architecture, but features 2.048V internal reference and 2.7–3.6V supply range. | Designed for 3.3V systems - cannot operate at 5V; reference mismatch affects full-scale range and noise floor in 5V designs. | Use only in 3.3V applications where 2.048V reference aligns with system VREF; not a drop-in replacement for MAX11604EEE+T. |
Compared with ADS7822U and MAX11605EEE+, the MAX11604EEE+T uniquely combines 5V operation, integrated 4.096V reference, and I²C interface in a single 16-pin QSOP - minimizing design iteration for industrial 5V sensor hubs requiring rapid time-to-market.

FAQ
What supply voltage range does the MAX11604EEE+T support?
The MAX11604EEE+T operates strictly from 4.5V to 5.5V - it is not compatible with 3.3V or lower supplies. This distinguishes it from the MAX11605EEE+, which uses 2.7V–3.6V. Using incorrect voltage risks functional failure or damage, as confirmed by Absolute Maximum Ratings specifying VDD to GND stress limit of -0.3V to +6V.
Does the MAX11604EEE+T require an external reference voltage?
No, the MAX11604EEE+T includes a factory-trimmed 4.096V internal reference with ±0.5% initial accuracy and 120ppm/°C temperature coefficient. External reference is optional and supported over 1V to VDD, but using the internal reference eliminates component count and layout complexity - a key design advantage confirmed in the Electrical Characteristics table.
How many analog input channels does the MAX11604EEE+T provide?
The MAX11604EEE+T provides 12 analog input channels, configurable as 12 single-ended or 6 pseudo-differential pairs. This is explicitly stated in the Ordering Information table and reinforced in the General Description: "MAX11604/MAX11605 provide 12 analog input channels." Pin 1 (AIN11/REF) and pins 2–12 (AIN0–AIN10) constitute the full 12-channel set.
What is the maximum I²C clock frequency supported by the MAX11604EEE+T?
The MAX11604EEE+T supports I²C high-speed mode up to 1.7MHz, as specified in the Timing Characteristics section. This enables sub-10µs readout latency per conversion result. Fast-mode (400kHz) is also supported, but high-speed mode is required to achieve the full 188ksps throughput rate with minimal bus overhead.
Is the MAX11604EEE+T pin-compatible with other devices in the MAX11600–MAX11605 family?
The MAX11604EEE+T shares the same 16-pin QSOP package and pinout with MAX11602EEE+, MAX11603EEE+, and MAX11605EEE+, but differs electrically from MAX11600/MAX11601 (8-pin SOT23). However, pin compatibility does not imply functional interchangeability - MAX11605EEE+ uses 2.048V reference and 2.7–3.6V supply, making it unsuitable as a direct replacement without system-level validation.
