MAX192BCAP

ADCs/DACs - Special Purpose Overview

The MAX192BCAP 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 successive approximation register (SAR) architecture. Operating on a single +5V supply, it supports software-configurable single-ended and differential inputs. The device features a 4-wire serial interface compatible with SPI, QSPI, and Microwire protocols. Key electrical parameters include a 133ksps sampling rate, internal 4.096V reference, and ±1 LSB INL/DNL accuracy. It operates within a commercial temperature range of 0°C to +70°C in a 20-pin SSOP package.

ADCs/DACs - Special Purpose Feature Summary

• 8-Channel Multiplexer: Supports single-ended or 4-channel differential input configurations via software control.
• Low Power Consumption: Draws 1.5mA during operation and reduces to under 10µA in full power-down mode.
• Integrated Reference: Includes an internal 4.096V reference with ±30ppm/°C typical drift and a reference-buffer amplifier.
• Flexible Serial 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 specific suffix 'BCAP' corresponds to the 0°C to +70°C temperature grade and 20-pin SSOP package. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as lead-free variants may carry different suffixes. Ensure the source document explicitly lists this part number to avoid confusion with pin-compatible 12-bit upgrades like the MAX186/MAX188.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192BCAP for applications requiring 10-bit resolution at 133ksps with low power consumption. Choose this variant over the 'E' series if the operating environment remains within 0°C to +70°C. Verify that the system can accommodate the 20-pin SSOP footprint, which occupies 30% less area than an 8-pin DIP. Consider the internal clock mode for simplified microprocessor timing requirements.

ADCs/DACs - Special Purpose Part Context

The MAX192 belongs to a family of low-cost, serial data-acquisition systems. The 'B' suffix denotes ±1 LSB integral nonlinearity (INL) and differential nonlinearity (DNL), while 'C' indicates the commercial temperature range. The 'AP' suffix specifies the 20-pin shrink-small-outline package (SSOP). This component serves as a precursor or alternative to higher-resolution devices like the MAX186/MAX188, offering pin compatibility for potential upgrades.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192ACAP is a pin-compatible alternative with tighter linearity specifications (±1/2 LSB INL/DNL) but shares the same package and temperature range. For industrial temperature ranges (-40°C to +85°C), consider the MAX192AEAP or MAX192BEAP. Higher-resolution 12-bit upgrades such as the MAX186 or MAX188 are also pin-compatible replacements.
