Frequently Asked Questions
How many analog input channels does PCM1851APJTR support and at what resolution?
The PCM1851APJTR integrates 12 analog input channels with 24-bit delta-sigma conversion resolution, enabling simultaneous high-fidelity digitization of a full 12-channel audio mix in a single IC, eliminating the need for multiple discrete ADCs.
What serial output format does PCM1851APJTR use and which downstream devices can it connect to directly?
It outputs audio data in standard I2S serial format using 2s-complement binary coding, making it directly compatible with audio DSPs, SoC I2S receivers, FPGA audio IP cores, and digital signal processors without any additional format conversion circuitry.
What is the maximum analog input voltage PCM1851APJTR can handle before clipping?
The analog input voltage maximum is 2 V, suitable for line-level signals after appropriate input attenuation; exceeding this level causes clipping in the delta-sigma modulator front-end, so a precision input buffer with gain control is recommended for high-level sources.
How does PCM1851APJTR compare to a 2-channel 24-bit ADC for an 8-channel recording interface design?
Using PCM1851APJTR's 12-channel monolithic integration versus six separate 2-channel ADCs reduces component count by at least 5 ICs, lowers BOM cost, simplifies clock synchronization to a single master clock, and shrinks PCB area by roughly 40% in typical 8-channel mixer designs.
