Working Principles

The MAX1090AEEI+T is a successive approximation type ADC. It utilizes a capacitor array and a comparator to convert the input analog voltage into a digital representation. The internal clock generates a series of pulses that control the conversion process. The input voltage is compared with the reference voltage, and the comparator determines the output bit by bit until the entire 10-bit digital value is obtained.

Detailed Application Field Plans

• Industrial automation: Process control, data acquisition systems
• Medical equipment: Patient monitoring, diagnostic devices
• Communication systems: Base stations, wireless transceivers
• Automotive electronics: Engine control, sensor interfaces
• Consumer electronics: Audio/video processing, gaming consoles
