MAX11046ETN+

Analog To Digital Converters (ADC) Overview

The MAX11046ETN+ is an 8-channel, 16-bit simultaneous-sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features independent track-and-hold and SAR circuitry for each channel, enabling a throughput rate of 250ksps per channel with a fast 3µs conversion time. The device accepts ±5V inputs protected by internal clamps and operates on a single 4.75V to 5.25V analog supply and a flexible 2.7V to 5.25V digital supply. It includes a low-drift 4.096V internal reference or supports external references between 3.0V and 4.25V. Data is transferred via a 20MHz bidirectional parallel interface in a 56-pin TQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across all channels using independent track-and-hold circuits
• High-impedance analog inputs up to 1GΩ with overrange protection
• Integrated low-drift bandgap reference providing ±5V input range
• Bidirectional 16-bit parallel interface supporting 20MHz data rates

Analog To Digital Converters (ADC) Applications

• Automatic Test Equipment
• Power-Factor Monitoring and Correction
• Multiphase Motor Control
• Vibration and Waveform Analysis

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix ETN+ corresponds to the 56-pin TQFN package with an exposed pad when sourcing. Confirm RoHS compliance status as indicated by the plus sign. Ensure the host system supports the required 20MHz parallel interface timing and voltage levels for both analog and digital supplies before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high channel count and precise phase alignment without external multiplexing. Compare against the MAX11044 and MAX11045 if fewer channels are sufficient. Consider the MAX11056 if 14-bit resolution meets requirements while maintaining the same pinout and functionality.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX1104x/MAX1105x family of high-speed simultaneous-sampling ADCs. It shares architectural similarities with the MAX11044 and MAX11045 but provides eight independent input channels instead of four or six. The family is designed for precision data acquisition systems requiring synchronized multi-channel sampling.

Analog To Digital Converters (ADC) Replacement Considerations

MAX11046ECB+ offers the same electrical specifications in a 64-pin TQFP package.
