Maxim Integrated MAX1358BETL W

Description
The MAX1358B is a smart data-acquisition system (DAS) that integrates a 16-bit sigma-delta ADC, DACs, operational amplifiers, voltage references, temperature sensors, analog switches, an oscillator, a real-time clock (RTC), a high-frequency-locked loop (FLL) clock, user-programmable I/Os, an interrupt generator, and voltage monitors. It operates from a single 1.8V to 3.6V supply and consumes only 1.15mA in normal mode and 3μA in sleep mode.
