MAX192AEPP+

ADCs/DACs - Special Purpose Overview

The MAX192AEPP+ 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, and a successive approximation register (SAR) architecture. The device operates on a single +5V supply with a sampling rate of 133 kS/s. Key electrical parameters include a resolution of 10 bits, INL of ±0.5 LSB, DNL of ±1 LSB, and power dissipation of 889 mW. It features an internal 4.096V reference and supports SPI, QSPI, and Microwire interfaces in a 20-pin PDIP package.

ADCs/DACs - Special Purpose Feature Summary

• 8-Channel Multiplexer: Supports single-ended or differential input configurations via software control.
• Low Power Consumption: Operates at 1.5 mA during active mode and reduces to under 10 µA in full power-down mode.
• Integrated Reference: Includes an internal 4.096V reference with ±30 ppm/°C temperature coefficient.
• Serial Interface Compatibility: Connects directly to SPI, QSPI, Microwire, and TMS320 DSPs without external logic.

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the component status as the MAX192AEPP+ may be listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure the ordering suffix corresponds to the specific temperature range (-40°C to +85°C) and package type (PDIP-20) required for the design.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192AEPP+ when a low-cost, 10-bit ADC with multiple channels is required. The 'E' suffix indicates an extended temperature range of -40°C to +85°C. Compare against the MAX192BEPP+ if higher integral nonlinearity accuracy (±1 LSB vs ±0.5 LSB) is not critical but cost reduction is needed. Ensure the system supports the required serial clock frequencies up to 4 MHz.

ADCs/DACs - Special Purpose Part Context

The MAX192AEPP+ belongs to the MAX192 family of low-power data acquisition systems. It is pin-compatible with the 12-bit MAX186/MAX188 series, allowing for potential upgrades in resolution without PCB redesign. The device is part of Maxim Integrated's portfolio, now under Analog Devices, focusing on efficient signal conditioning and conversion for embedded applications.

ADCs/DACs - Special Purpose Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider the MAX192BEPP+ for functional equivalence with different linearity specifications, or the MAX186/MAX188 for pin-compatible 12-bit upgrades.
