MAX192BCWP+

ADCs/DACs - Special Purpose Overview

The MAX192BCWP+ 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 a 4-wire serial interface compatible with SPI, QSPI, and Microwire protocols. Operating on a single +5V supply, the device features an internal 4.096V reference with ±30ppm/°C drift and supports both single-ended and differential input configurations. The MAX192BCWP+ variant utilizes a 20-pin Wide SO package and operates within a temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Feature Summary

• 8-Channel Multiplexer: Supports single-ended or 4-channel differential inputs with software configurability.
• High-Speed Conversion: Internal track/hold enables a sampling rate of 133ksps with a 4.5MHz small-signal bandwidth.
• Integrated Reference: Includes an internal 4.096V reference buffer amplifier to simplify gain trimming.
• Low Power Consumption: Consumes 1.5mA in operating mode and reduces to under 10µA in full power-down mode.

ADCs/DACs - Special Purpose Applications

• Portable Data Logging
• Battery-Powered Instruments
• Medical Instruments
• Robotics

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm the 'BC' suffix indicates the commercial temperature grade (0°C to +70°C) and 'WP' denotes the 20-pin Wide SOIC package. Check for RoHS compliance status associated with the '+' suffix. Ensure the specific lot date code meets project requirements given the component's age.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192BCWP+ when an 8-channel multiplexed ADC with serial interface is required. Choose this part over the MAX192ACWP+ if tighter linearity specifications are needed, as the 'B' grade offers improved accuracy. Ensure the system design accommodates the 20-pin Wide SOIC footprint and provides adequate thermal dissipation for the plastic package.

ADCs/DACs - Special Purpose Part Context

The MAX192 belongs to a family of low-cost, serial data-acquisition systems. The MAX192BCWP+ is the commercial-grade version in a 20-pin Wide SOIC package. It serves as a pin-compatible upgrade path to the 12-bit MAX186/MAX188 series while maintaining software compatibility. The device is designed for applications requiring multiple analog inputs with minimal microprocessor overhead.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192ACWP+ is a direct pin-compatible alternative with slightly relaxed linearity specifications. For higher resolution needs, the MAX186 or MAX188 offer 12-bit performance in the same package. No other direct cross-model replacements are documented in the provided source material.
