MAX11049ETN+T

Analog To Digital Converters (ADC) Overview

The MAX11049ETN+T is an 8-channel, 16-bit simultaneous-sampling analog-to-digital converter (ADC) in a 56-pin TQFN package. It features independent track-and-hold and SAR circuitry for each channel, enabling 250ksps throughput per channel with a fast 3µs conversion time. The device accepts 0V to +5V input signals and includes overrange protection via internal ±20mA clamps. It operates on a single 4.75V to 5.25V analog supply and a flexible 2.7V to 5.25V digital supply. Key specifications include a 4MHz T/H bandwidth, 10ns aperture delay, and a low-drift 4.096V internal reference.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging when sourcing. Confirm the component is lead-free and RoHS compliant as indicated by the '+' designation. Ensure the 56-pin TQFN package matches the design footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high-speed, multi-channel data acquisition with precise channel synchronization. The 16-bit resolution and 250ksps rate suit precision measurement tasks. Consider the external reference range of 3.0V to 4.25V if custom full-scale ranges are needed.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX1104x/MAX1105x family of simultaneous-sampling ADCs. The MAX11049 variant specifically provides 8 channels at 16-bit resolution, whereas the MAX11047 offers 4 channels and the MAX11048 offers 6 channels in the same packages.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11049ECB+ is a parameter-equivalent alternative available in a 64-pin TQFP package. Verify pin compatibility and thermal performance differences between the TQFN and TQFP options.
