MAX192BCPP Data Acquisition 10b 133k Serial 20-PDIP

Description

MAX192BCPP Data Acquisition 10b 133k Serial 20-PDIP The MAX192BCPP is a fully integrated, low-cost data-acquisition system. It combines an 8-channel multiplexer, a high-bandwidth track/hold circuit, and a successive-approximation ADC onto a single chip. This integration simplifies the process of converting multiple analog signals into a digital serial data stream, requiring only a single +5V power supply for operation. The device is designed for ease of use in various measurement and control systems. A key aspect of the MAX192BCPP is its software-configurable analog inputs, which can be set up for either 8-channel single-ended or 4-channel differential operation. This pseudo-differential input structure allows for versatile signal measurement. Furthermore, the device includes a built-in 4.096V voltage reference, which can be used directly or bypassed in favor of an external, more precise reference to meet specific accuracy requirements. Data is output through a versatile 4-wire serial interface that is directly compatible with standard protocols like SPI and Microwire, facilitating easy connection to microprocessors. To enhance power efficiency in portable or low-power applications, the MAX192BCPP features multiple power-down modes, including a hardwired shutdown pin and two software-selectable options, allowing the supply current to be drastically reduced between conversions.
