Analog To Digital Converters (ADC) datasheet and documents for LTC1404IS8#PBF
Analog To Digital Converters (ADC) Overview
The LTC1404IS8#PBF is a high-speed, low noise monolithic switching regulator manufactured by Analog Devices. It operates from a single supply voltage ranging from 2.7V to 5.5V and delivers an adjustable output voltage between 1.23V and the input rail. The device integrates a 1.4MHz fixed-frequency oscillator, error amplifier, and power switches within an 8-lead SOIC package. Key electrical specifications include a quiescent current of 10µA, a maximum output current of 600mA, and a shutdown mode that reduces supply current to less than 1µA. It features cycle-by-cycle current limit protection and thermal shutdown capabilities.
Analog To Digital Converters (ADC) Feature Summary
