MAX192ACWP+T

ADCs/DACs - Special Purpose Overview

The MAX192ACWP+T is a low-power, 8-channel, serial 10-bit analog-to-digital converter (ADC) from the MAX192A series. 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 133 kS/s. It features a 4-wire serial interface compatible with SPI, QSPI, and Microwire protocols. The component includes an internal 4.096V reference and supports both single-ended and differential input configurations. It is housed in 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 software-configurable single-ended or differential (unipolar/bipolar) inputs.
• Low Power Consumption: Draws 1.5mA during operation and reduces to under 10µA in full power-down mode.
• Internal Reference: Includes a 4.096V reference with ±30ppm/°C typical drift and a buffer amplifier.
• Serial Interface: 4-wire interface 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 ordering suffix '+T' indicates tape-and-reel packaging as per standard Maxim Integrated conventions for this part number. Confirm the 'AC' grade specifies the commercial temperature range (0°C to +70°C) and accuracy class. Ensure the source document explicitly lists the MAX192ACWP+T variant to validate the specific package and revision.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192ACWP+T when a 10-bit resolution with 8 channels is required in a surface-mount Wide SO package. Choose this model over the DIP version if board space is limited. Ensure the application requires a single +5V supply and can utilize the internal 4.096V reference or an external one via the VREF pin.

ADCs/DACs - Special Purpose Part Context

The MAX192ACWP+T belongs to the MAX192 family of low-cost, low-power data acquisition systems. It is pin-compatible with the 12-bit MAX186/MAX188 for potential upgrades. The 'AC' designation denotes the commercial temperature range, while 'WP' identifies the 20-pin Wide SOIC package. The '+' suffix typically indicates lead-free/RoHS compliance.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192AEWP+T is a verified substitute offering an extended industrial temperature range (-40°C to +85°C) with identical pinout and functionality. The MAX192BCWP+T provides the same package but may differ in linearity specifications (INL/DNL). Verify temperature requirements before substitution.
