MAX11628EEE+T

Analog To Digital Converters (ADC) Overview

The MAX11628EEE+T is a serial 12-bit analog-to-digital converter (ADC) featuring an internal 4.096V reference and an 8-channel analog multiplexer with track-and-hold. It operates from a single 4.75V to 5.25V supply and supports sampling rates up to 300ksps using an external clock. The device includes a 16-entry FIFO buffer, scan mode, internal averaging, and AutoShutdown functionality. It utilizes a 10MHz SPI-/QSPI-/MICROWIRE-compatible interface and is housed in a 16-pin QSOP package.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements and interface protocols before integration. Cross-reference part numbers with manufacturer databases to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel ADC with integrated FIFO and internal reference is required. Verify that the 4.75V to 5.25V supply range matches the system design. Consider the 16-pin QSOP package dimensions for PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

The MAX11628EEE+T belongs to the MAX11626–MAX11629/MAX11632/MAX11633 family of 12-bit, 300ksps ADCs. This series offers varying channel counts and supply voltages, with the MAX11628 specifically designed for 8-channel applications requiring a +5V supply.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11628EEE+ is the non-tape-and-reel equivalent. Other family members include MAX11626 (4-channel), MAX11629 (8-channel, 3V), MAX11632 (16-channel, 5V), and MAX11633 (16-channel, 3V).

Analog To Digital Converters (ADC) FAQ

What is the maximum sampling rate supported by the MAX11628?

The maximum sampling rate is 300ksps when using an external clock.

How many analog input channels does the MAX11628 support?

The MAX11628 supports 8 single-ended analog input channels.
