MX7828KP

Analog To Digital Converters (ADC) Overview

The MX7828KP+ is an 8-bit, high-speed analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features a half-flash architecture with an integrated multiplexer supporting four or eight single-ended inputs. The device operates on a single 5V supply and delivers a sampling rate of 400 kS/s. Data output is provided via a serial peripheral interface (SPI). Packaged in a 28-PLCC surface-mount format, it functions within a commercial temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Half-flash ADC architecture for high-speed conversion
• Integrated multiplexer supporting 4 or 8 single-ended channels
• Serial SPI data interface for simplified system integration
• Single 5V power supply operation

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data acquisition modules for sensor monitoring
• Portable instrumentation utilizing low-power serial interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as discontinued or limited supply through official manufacturer channels. Confirm RoHS3 compliance and specific package markings against the datasheet. Ensure the ordering suffix matches the required PLCC-28 variant. Check for obsolescence notices prior to design finalization.

Analog To Digital Converters (ADC) Selection Notes

Select this model when an 8-bit resolution and 400 kS/s throughput are sufficient for the application. The SPI interface reduces pin count compared to parallel alternatives. Verify that the 0°C to +70°C operating range meets environmental requirements. Consider the PLCC-28 footprint constraints during PCB layout.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MX7828 series of high-speed ADCs. Other variants include the MX7828KN+ (parallel interface, PDIP package) and MX7828LCWI+ (SOIC package). The KP suffix specifically denotes the 28-PLCC surface-mount package configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements are not publicly confirmed for this specific package variant. Evaluate the MX7828KN+ if a parallel interface and through-hole packaging are acceptable alternatives.
