MAX192BEAP+T

ADCs/DACs - Special Purpose Overview

The MAX192BEAP+T 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 BE suffix indicates an extended temperature range of -40°C to +85°C, while the AP suffix denotes a 20-pin shrink-small-outline package (SSOP).

ADCs/DACs - Special Purpose Feature Summary

• 8-Channel Multiplexer: Supports software-configurable single-ended or differential (unipolar/bipolar) inputs.
• High-Speed Conversion: Internal track/hold provides a 133kHz sampling rate with 1.5µs acquisition time.
• Low Power Consumption: Operates at 1.5mA in active mode and reduces to under 10µA in power-down modes.
• Integrated Reference: Includes an internal 4.096V reference buffer amplifier to simplify gain trimming.

ADCs/DACs - Special Purpose Applications

• Portable Data Logging Systems
• Battery-Powered Instruments and Management
• Medical Instrumentation
• Robotics Control Systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix 'BEAP' confirms the -40°C to +85°C temperature range and SSOP-20 package. Confirm RoHS compliance status for the '+T' tape-and-reel variant. Check for obsolescence notices as older Maxim products may have limited availability or end-of-life status.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a multi-channel ADC with low power consumption and serial interface compatibility is required. Ensure the system voltage matches the single +5V requirement. For higher resolution needs, consider pin-compatible 12-bit upgrades like the MAX186/MAX188. Verify that the source impedance allows for the specified 1.5µs acquisition time.

ADCs/DACs - Special Purpose Part Context

The MAX192 series belongs to Maxim's low-cost data-acquisition family. The MAX192BEAP+T specifically combines the B-grade accuracy (±1 LSB INL/DNL) with the E-grade temperature range and AP-grade SSOP packaging. It offers hardware and software compatibility with the MAX186/MAX188 series for easy migration paths.

ADCs/DACs - Special Purpose Replacement Considerations

Pin-compatible alternatives include the MAX186 and MAX188 for 12-bit resolution upgrades. Other MAX192 variants with different temperature ranges or packages (e.g., MAX192ACAP, MAX192BCPP) may be suitable if environmental conditions allow.
