MAX192ACPP

Analog To Digital Converters (ADC) Overview

The MAX192ACPP is a low-power, 8-channel, serial 10-bit analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It features a successive-approximation architecture with an internal track-and-hold circuit and operates on a single +5V supply. The device supports both single-ended and differential input configurations via software control. It includes an internal 4.096V reference and offers a 4-wire serial interface compatible with SPI, QSPI, and Microwire protocols. Operating within a temperature range of 0°C to +70°C, it provides a sampling rate of 133ksps with power consumption as low as 2µA in full power-down mode.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with high-bandwidth track-and-hold for efficient multi-point data acquisition.
• Features a flexible 4-wire serial interface that connects directly to standard microprocessor buses without external logic.
• Includes an internal 4.096V reference with low drift and a reference-buffer amplifier to simplify gain trimming.
• Offers multiple power-down modes allowing supply current reduction to under 10µA between conversions.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix ACPP confirms the 0°C to +70°C industrial temperature range and PDIP-20 package. Confirm RoHS compliance status if required by your assembly process. Check for obsolescence notices as this component series may be subject to discontinuation. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX192ACPP when an 8-channel multiplexed input is required alongside 10-bit resolution at moderate speeds. Consider the internal clock mode for simplified timing or external clock for precise synchronization. Verify that the source impedance of the analog inputs allows for the specified 1.5µs acquisition time. Ensure the system voltage aligns with the single +5V operating requirement.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX192 family of low-power ADCs. It is pin-compatible with the 12-bit MAX186 and MAX188, facilitating potential upgrades. The AC suffix denotes the industrial temperature grade, while PP indicates the plastic DIP package. It serves as a cost-effective solution for general-purpose data acquisition systems requiring moderate precision and channel count.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX192AEPP is available as a wider temperature range (-40°C to +85°C) alternative within the same package. For higher resolution requirements, the pin-compatible MAX186 or MAX188 offer 12-bit performance. Verify that any substitute maintains the same serial interface timing characteristics and power supply requirements.
