LTC1392CN8#PBF

Thermal Management Overview

The LTC1392CN8#PBF is a micropower data acquisition system in an 8-lead PDIP package. It integrates a temperature sensor, power supply monitor, and a 10-bit successive approximation ADC with rail-to-rail differential voltage input. The device operates on a single 4.5V to 6V supply, drawing 0.2μA when idle and 700μA during sampling. It features a 3-wire half-duplex serial interface for MPU communication.
