Frequently Asked Questions
What bit resolution and input format does the PCM1719EG4 use for audio conversion?
The PCM1719EG4 is an 18-bit stereo DAC that accepts serial audio data in 2's complement binary format. This 18-bit resolution provides up to 110 dB dynamic range, making it suitable for high-fidelity audio applications such as CD players and AV receivers where audio quality exceeds the 16-bit CD standard by 12 dB of headroom.
What is the maximum analog output voltage of the PCM1719EG4 and is it sufficient for line-level audio outputs?
The PCM1719EG4 delivers a maximum analog output voltage of 3.1 V, which meets the standard line-level output requirement of approximately 1 Vrms to 2 Vrms for consumer audio equipment. This output level allows direct connection to line inputs, preamplifiers, or active filters without an additional gain stage, reducing component count in stereo audio playback circuit designs.
Is the PCM1719EG4 a RoHS-compliant part and what does the G4 suffix mean for procurement?
The PCM1719EG4 carries a Pb-free code of No per its spec sheet entry, meaning the standard G4 tray version may use SnPb solder finish per the JESD-609 code e4. Engineers designing for EU RoHS compliance should verify the specific finish and consult TI's product page. The G4 suffix denotes the standard green (halogen-free) 28-pin SOIC tray packaging with a 7.5 mm body width.
How does PCM1719EG4 compare to a 24-bit DAC for a consumer CD player design?
The PCM1719EG4 at 18-bit resolution provides approximately 110 dB dynamic range, which exceeds the 96 dB theoretical maximum of a 16-bit CD source. A 24-bit DAC would offer 144 dB theoretical dynamic range but is unnecessary for CD playback since the source material is limited to 16 bits. The PCM1719EG4 represents a cost-effective precision match for CD, DAT, and similar 16-bit to 18-bit digital audio sources with analog output up to 3.1 V.
