MAX11046ETN+T

Analog To Digital Converters (ADC) Overview

The MAX11046ETN+T is an 8-channel, 16-bit simultaneous-sampling analog-to-digital converter (ADC) from Analog Devices/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 utilizes a 20MHz bidirectional parallel interface and includes an internal low-drift 4.096V reference or supports external references between 3.0V and 4.25V.

Analog To Digital Converters (ADC) Feature Summary

• Independent track-and-hold circuits for each channel ensure high-precision simultaneous sampling across all eight inputs.
• High-impedance analog inputs up to 1GΩ provide minimal loading on signal sources while maintaining accuracy.
• Integrated low-drift internal reference simplifies design by eliminating the need for external precision voltage sources.
• Flexible digital supply range allows direct interfacing with host processors without requiring level shifters.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through authorized distributors or manufacturer channels. Confirm the package type matches the required PCB footprint and check RoHS compliance status. Ensure the operating temperature range aligns with system requirements before finalizing procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this model when eight independent channels require simultaneous sampling at high speeds. Consider the 16-bit resolution and ±5V input range for applications demanding high dynamic performance. Evaluate the parallel interface compatibility with the host controller's data bus width and timing constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1104x family of high-speed, multi-channel ADCs. It shares architectural similarities with the MAX11044 and MAX11045 but provides eight channels instead of four or six. The ETN suffix indicates a 56-pin TQFN package with an exposed pad for thermal management.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11046BETN+T is a B-grade variant within the same series offering different linearity specifications. Other family members like the MAX11044ETN+T or MAX11045ETN+T offer fewer channels but share similar electrical characteristics and pinouts.
