Description
In addition, the MAX1361/MAX1362 integrate an internal voltage reference, a clock, and a 1.7MHz, high-speed, I²C-compatible, 2-wire, serial interface. The optimized interface allows a maximum conversion rate of 94.4ksps in normal mode while reading back the conversion results. Each of the four analog inputs is configurable for single-ended or fully differential operation and unipolar or bipolar operation. Two scan modes utilize on-chip random access memory (RAM) to allow eight conversions of a selected channel or scanning of a group of channels to reduce interface overhead.
These devices operate from a single 2.7V to 3.6V (MAX1361) or 4.5V to 5.5V (MAX1362) supply and require only 436µA at the maximum sampling rate of 150ksps in monitor mode and 670µA at the maximum sampling rate of 94.4ksps. AutoShutdown™ powers down the devices between conversions, reducing supply current to less than 0.5µA when idle.
The full-scale analog-input range is determined by the internal reference or by an externally applied reference voltage ranging from 1V to VDD. The MAX1361 features a 2.048V internal reference, and the MAX1362 features a 4.096V internal reference.
The MAX1361/MAX1362 are available in a 10-pin µMAX® package and are specified over the extended -40°C to +85°C temperature range. For 12-bit applications, refer to the pin-compatible MAX1363/MAX1364 data sheet.
