Maxim Integrated MAX1359BETL

Description
The MAX1358/MAX1359/MAX1360 are smart data-acquisition systems (DAS) that integrate a 16-bit sigma-delta analog-to-digital converter (ADC), DACs, operational amplifiers, a voltage reference, temperature sensors, analog switches, a 32kHz oscillator, a real-time clock (RTC) with alarm, a high-frequency-locked loop (FLL) clock, user-programmable I/Os, an interrupt generator, and voltage monitors.
