PCM4222PFB

ADCs/DACs - Special Purpose Overview

The PCM4222PFB is a high-performance audio analog-to-digital converter (ADC) manufactured by Texas Instruments. It features two independent converters with a resolution of 24 bits and supports sampling rates up to 216 kHz. The device utilizes a serial 3-wire interface for data communication. It operates within an analog and digital supply voltage range of 2.4 V to 4.2 V, with specific absolute maximum ratings indicating a minimum operating voltage of 3.9 V and a maximum of 4.2 V in certain contexts. The component is housed in a 48-TQFP package measuring 7x7 mm and is designed for surface mount installation. It functions reliably across a temperature range of -40°C to +85°C.
