It communicates over a PCM audio interface and operates from a single 4.75V to 5.25V supply for both analog and digital rails. The industrial temperature range (-40°C to 85°C) suits outdoor telecom infrastructure, conference-room audio processors, or industrial voice-command modules where the board sees ambient extremes. ## Four channels, one package — what that means for the BOM With 4 ADCs and 4 DACs on-chip, this codec replaces up to eight single-channel converters plus the glue logic for synchronisation. That saves board area and simplifies the PCM bus routing — one interface handles all four channels. The 64-PQFP (14x14 mm) footprint is a standard surface-mount package that reflows without special handling, though the fine pitch (0.8 mm typical for QFP) demands careful solder-paste stencil design to avoid bridges. ## Lifecycle and compliance — no obsolescence headache ROHS3 compliance means it meets the latest EU restriction levels, no exemption paperwork needed. For a production BOM line this is a straightforward qualification — no LTB risk, no successor to chase.","metaTitle":"821054PQFG PCM Codec, Quad ADC/DAC, 64-QFP, Active","metaDescription":"821054PQFG is a quad PCM codec with filter, 4 ADCs / 4 DACs, PCM audio interface, industrial temp -40 to 85°C, 64-QFP.
