MAX192BEWP

ADCs/DACs - Special Purpose Overview

The MAX192BEWP 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 serial interface compatible with SPI, QSPI, Microwire, and TMS320 DSPs. Operating on a single +5V supply, it features an internal 4.096V reference and supports both single-ended and differential input configurations. The device utilizes successive approximation architecture with a sampling rate of 133ksps. It operates within a temperature range of -40°C to +85°C and is housed in a 20-pin Wide SO package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'W' indicates the 20-pin Wide SO package and 'E' denotes the -40°C to +85°C industrial temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering part number matches the required package style and temperature grade for the intended application environment.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX192BEWP when a 20-pin Wide SO package is required for the -40°C to +85°C temperature range. The 'B' grade specifies ±1 LSB INL and DNL accuracy. Consider the MAX192AEWP if ±1/2 LSB accuracy is sufficient and cost optimization is needed. Verify that the system's serial interface timing meets the setup and hold requirements for DIN, SCLK, and CS signals.

ADCs/DACs - Special Purpose Part Context

The MAX192BEWP belongs to the MAX192 family of low-cost, 10-bit data-acquisition systems. It is pin-compatible with the 12-bit MAX186/MAX188, allowing for potential upgrades without PCB redesign. The device is designed for applications requiring multiple analog inputs with moderate resolution and low power consumption, serving as a bridge between analog sensors and digital processing units.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX192AEWP is a direct pin-compatible replacement offering ±1/2 LSB INL/DNL accuracy within the same -40°C to +85°C temperature range and 20-pin Wide SO package. Other MAX192 variants differ by package type (DIP, SSOP) or temperature range.
