MAX192AEAP+

ADCs/DACs - Special Purpose Overview

The MAX192AEAP+ 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, Microwire, and TMS320 DSPs. Operating on a single +5V supply, it features an internal 4.096V reference with ±30ppm/°C drift and supports both single-ended and differential input configurations. The device utilizes successive approximation architecture with a sampling rate of 133ksps. It offers hardware shutdown and software-selectable power-down modes to minimize current consumption.

ADCs/DACs - Special Purpose Feature Summary

• 8-Channel Multiplexer: Supports single-ended or 4-channel differential inputs with pseudo-differential architecture.
• Low Power Consumption: Draws 1.5mA in operating mode and reduces to under 10µA in full power-down mode.
• Integrated Reference: Includes an internal 4.096V reference buffer amplifier with ±30ppm/°C temperature coefficient.
• Flexible Serial Interface: Connects directly to SPI, QSPI, Microwire, and TMS320 devices without external logic.

ADCs/DACs - Special Purpose Applications

• Automotive systems
• Pen-entry systems
• Portable data logging
• Battery-powered instruments and management
• Medical instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'AP' indicates the SSOP package variant when sourcing. Confirm the 'E' grade corresponds to the -40°C to +85°C industrial temperature range required for the application. Check RoHS compliance status as indicated by the '+' suffix in ordering information.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring multi-channel acquisition with low power constraints. Ensure the source impedance is managed to meet the 1.5µs acquisition time requirement. Choose between internal clock mode for processor convenience or external clock mode for precise timing synchronization with the system bus.

ADCs/DACs - Special Purpose Part Context

The MAX192AEAP+ belongs to the MAX192 family of low-cost, 10-bit data-acquisition systems. It is pin-compatible with the 12-bit MAX186/MAX188 series, allowing for potential upgrades. The 'AEAP' designation specifies the industrial temperature range (-40°C to +85°C) and the 20-pin shrink-small-outline package (SSOP).

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192BEAP+ serves as a pin-compatible alternative within the same package and temperature range, offering improved linearity specifications (±1 LSB INL vs ±0.5 LSB). For higher resolution needs, the MAX186 or MAX188 series provides a 12-bit upgrade path with identical pinouts.
