MAX188CCPP

Analog To Digital Converters (ADC) Overview

The MAX188CCPP+ is a 12-bit successive-approximation analog-to-digital converter (ADC) featuring an 8-channel multiplexer and high-bandwidth track/hold circuit. It operates on a single +5V or dual ±5V supply with software-configurable unipolar/bipolar and single-ended/differential inputs. The device utilizes a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. Unlike the MAX186, the MAX188 requires an external reference voltage applied to the VREF pin. It supports internal or external clocking, offers fast power-down modes, and is available in 20-pin PDIP, SO, and SSOP packages.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with a high-bandwidth track/hold circuit for efficient data acquisition.
• Features a flexible 4-wire serial interface directly compatible with standard microprocessor protocols without external logic.
• Supports both internal and external clock sources to accommodate various system timing requirements.
• Includes a reference-buffer amplifier to simplify gain trimming and calibration processes.

Analog To Digital Converters (ADC) Applications

• Portable Data Logging
• High-Accuracy Process Control
• Battery-Powered Instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CPP' indicates the commercial temperature range and PDIP package configuration. Confirm RoHS compliance status for the specific manufacturing lot. Ensure the external reference voltage matches the required input specifications for the MAX188 variant.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX188 over the MAX186 when an external reference voltage is preferred or required for system flexibility. Consider the PDIP package for through-hole mounting needs. Evaluate the need for differential versus single-ended input configurations based on signal source characteristics.

Analog To Digital Converters (ADC) Part Context

The MAX188 belongs to the MAX186/MAX188 family of low-power, serial 12-bit ADCs. It shares architectural similarities with the MAX186 but differs primarily in its reference voltage handling, requiring an external source rather than utilizing an internal one. This family targets applications demanding moderate speed and precision with minimal power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

MAX186CCPP+ serves as a functional substitute if an internal reference is acceptable. Verify pin compatibility and software configuration differences regarding reference settings before substitution.
