ADPD103BCPZ

ADPD103BCPZ Description

The ADPD103BCPZ from Analog Devices Inc. is a highly integrated 4-channel Analog Front End (AFE) designed for precision optical sensing applications. This 14-bit resolution IC operates with both analog and digital supply voltages ranging from 1.7V to 1.9V, ensuring low-power operation suitable for battery-powered devices. Packaged in a compact 28LFCSP-WQ (Wafer-Level Chip-Scale Package), it is optimized for surface-mount assembly and complies with ROHS3 and REACH environmental standards. With a Moisture Sensitivity Level (MSL) of 3, it requires careful handling during PCB assembly.

ADPD103BCPZ Features

• Multi-Channel Flexibility: Four independent input channels enable simultaneous signal acquisition from multiple sensors, ideal for complex optical systems.
• High Resolution: 14-bit ADC ensures precise signal digitization for applications demanding high accuracy.
• Low-Voltage Operation: Dual-supply compatibility (1.7V–1.9V) minimizes power consumption, extending battery life in portable devices.
• Robust Integration: Combines analog signal conditioning, ADC, and digital processing in a single chip, reducing external component count.
