MAX192ACAP

Analog To Digital Converters (ADC) Overview

The MAX192ACAP is a low-power, 8-channel, serial 10-bit analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It integrates an 8-channel multiplexer, high-bandwidth track/hold circuit, and successive approximation register (SAR) architecture. The device operates on a single +5V supply with a sampling rate of 133ksps. It features a 4-wire serial interface compatible with SPI, QSPI, and Microwire protocols. An internal 4.096V reference with ±30ppm/°C drift is included. The component is housed in a 20-pin SSOP package and supports both single-ended and differential input configurations.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with software-configurable single-ended or differential inputs
• Features a 4-wire serial interface directly compatible with standard microprocessor protocols without external logic
• Includes an internal 4.096V reference with a buffer amplifier to simplify gain trimming
• Supports multiple power-down modes to reduce supply current to under 10µA between conversions

Analog To Digital Converters (ADC) Applications

• Portable data logging systems
• Battery-powered instruments and battery management
• Medical instrumentation
• Consumer electronics and pen-entry systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature range. Ensure that any pin-compatible replacements maintain identical electrical characteristics and serial interface timing requirements for direct substitution in existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a low-cost, single-supply ADC with integrated multiplexing is required. Consider the internal clock mode for simplified microprocessor interfacing or external clock mode for precise synchronization. Verify that the source impedance of the analog inputs allows for the specified acquisition time to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

The MAX192 belongs to the Maxim Integrated low-power ADC family, designed for cost-sensitive applications requiring moderate resolution and speed. It serves as a foundational component for multi-channel data acquisition systems where power consumption and board space are critical constraints.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX186 and MAX188 are pin-compatible 12-bit upgrades within the same series. Verify that the increased resolution and potential differences in control byte formats do not impact the existing system design.
