MAX1316ECM+

Analog To Digital Converters (ADC) Overview

The MAX1316ECM+ is a 14-bit, 8-channel simultaneous-sampling analog-to-digital converter (ADC) in a 48-pin LQFP package. It features independent track/hold circuitry for each channel to preserve phase information. The device supports a 0V to +5V unipolar input range with ±6.0V fault tolerance. It operates from a +4.75V to +5.25V analog supply and a separate +2.7V to +5.25V digital supply. Key performance metrics include a typical SNR of 76dB at 100kHz input, an internal 2.5V reference, and a maximum throughput of 250ksps per channel when all eight channels are active.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component matches the exact suffix 'ECM+' to ensure compliance with lead-free manufacturing standards and extended temperature ratings. Confirm that the supplier provides valid traceability documentation for this Analog Devices part number. Cross-reference the datasheet revision to ensure compatibility with your system design requirements before finalizing orders.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX1316ECM+ specifically for applications requiring eight independent channels with a 0V to +5V input range. Ensure the host system can accommodate the required parallel interface timing and voltage levels. Consider the thermal dissipation characteristics within the 48-pin LQFP package if operating near the upper temperature limits.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1316–MAX1318/MAX1320–MAX1322/MAX1324–MAX1326 family of high-speed ADCs. While sharing identical architectures, other members differ in channel count or input voltage ranges. This specific model is optimized for multi-phase signal acquisition where precise timing alignment between multiple inputs is critical.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same series include the MAX1317ECM+ (4-channel) and MAX1318ECM+ (2-channel). For different input ranges, consider the MAX1320ECM+ (±5V) or MAX1324ECM+ (±10V), noting that pinouts remain consistent across the family.

Analog To Digital Converters (ADC) FAQ

How does the device handle unused input channels?

Unused channels can be disabled via the internal configuration register, which reduces power consumption by turning off the corresponding track/hold amplifiers.

What is the fault tolerance level for the analog inputs?

The MAX1316ECM+ inputs are fault-tolerant up to ±6.0V relative to AGND, protecting the device from overvoltage conditions beyond the 0V to +5V operating range.

Can the conversion clock be sourced externally?

Yes, the INTCLK/EXTCLK pin allows selection between the internal 10MHz clock and an external clock signal applied to the CLK pin.
