MAX11359ACTL+中文资料美信数据手册PDF规格书

General Description

The MAX11359A smart data-acquisition systems (DAS) is based on a 16-bit, sigma-delta analog-to-digital converter (ADC) and system-support functionality for a microprocessor (µP)-based system. The device integrates an ADC, DAC, operational amplifiers, internal selectablevoltage reference, temperature sensors, analog switches, a 32kHz oscillator, a real-time clock (RTC) with alarm, a high-frequency-locked loop (FLL) clock, four user-programmable I/Os, an interrupt generator, and 1.8V and 2.7V voltage monitors in a single chip.
