Product details
Overview
The MAX1317ECM+ from Maxim Integrated is a 4-channel, 14-bit simultaneous-sampling analog-to-digital converter with 0 to +5V unipolar input range, ±6.0V fault-tolerant inputs, 2.5µs four-channel conversion time, and 357ksps per-channel throughput. It features independent track/hold per channel, internal +2.5V reference, and operates from +4.75V to +5.25V analog and +2.7V to +5.25V digital supplies - used in multiphase motor control and power-grid synchronization systems.
For engineers reviewing the MAX1317ECM+ datasheet, MAX1317ECM+ pinout, MAX1317ECM+ application, or MAX1317ECM+ equivalent, this page delivers verified specifications, real-world timing behavior, channel-specific fault tolerance, parallel interface timing constraints, and validated alternative options for industrial data acquisition designs.
Technical Context
The MAX1317ECM+ implements eight independent track/hold amplifiers (four active), enabling true simultaneous sampling across all enabled channels to preserve inter-channel phase relationships. Its 10MHz T/H input bandwidth supports high-fidelity capture of transient waveforms up to 100kHz with 76.5dB SINAD.
Conversion is controlled via a 16.6MHz 14-bit parallel interface with RD/WR/CS handshaking; internal clock operation at 10MHz yields deterministic 2.5µs four-channel conversion, while external clocking allows flexible timing alignment. The device uses separate analog/digital supplies and supports shutdown mode with ≤2µA total current draw.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7656ASTZ | 6-channel, ±10V bipolar input, SPI interface, no internal reference | Requires external reference and level-shifting for 0–5V sensors; better suited for high-voltage energy metering | Select when needing >4 channels or bipolar measurement; avoid for unipolar-only systems due to added complexity |

FAQ
What is the maximum sample rate per channel for the MAX1317ECM+?
The MAX1317ECM+ achieves 357ksps per channel when operating all four channels simultaneously. This throughput is measured with internal 10MHz clocking and reflects the time required to complete conversions across all enabled inputs while maintaining simultaneous sampling integrity. The value is confirmed in the Electrical Characteristics table under "External-Clock Throughput Rate" for four channels.
Does the MAX1317ECM+ require an external reference voltage?
No, the MAX1317ECM+ includes an internal +2.5V reference with ±30ppm/°C temperature coefficient, fully functional for most industrial applications. An external reference (2.0V–3.0V) may be used via REF and REFMS pins to improve absolute accuracy or enable system-level calibration - but it is not required for basic operation of the MAX1317ECM+.
How many analog input channels does the MAX1317ECM+ support, and what is their voltage range?
The MAX1317ECM+ supports exactly four analog input channels (CH0–CH3), each with a 0 to +5V unipolar input range. These channels feature ±6.0V fault-tolerant inputs, allowing safe operation in noisy industrial environments where transient overvoltages may occur - a specification explicitly defined in the Absolute Maximum Ratings table for MAX1317ECM+.
What package type and pin count does the MAX1317ECM+ use?
The MAX1317ECM+ is housed in a 48-pin LQFP package with a 7mm × 7mm footprint, as confirmed in the Ordering Information table and Pin Configurations section of the official datasheet. This package supports standard surface-mount assembly and provides adequate thermal performance for its 46mA analog supply current at full operation.
Can the MAX1317ECM+ operate with separate analog and digital supply voltages?
Yes, the MAX1317ECM+ requires two independent supplies: AVDD (+4.75V to +5.25V) for the analog section and DVDD (+2.7V to +5.25V) for the digital interface. This separation minimizes noise coupling and is mandatory per the Absolute Maximum Ratings and Electrical Characteristics sections - ensuring specified SNR and THD performance is maintained in mixed-signal PCB layouts.
