Philips has developed a 16-bit conversion system with a remarkable performance. The fundamental problem of quantisation noise is solved at source, before D/A conversion, using a digital oversampling filter and noise shaper.

Given a specification that had included a 14-bit data word length, they had duly developed a 14-bit DAC chip, the TDA1540, only then to be informed that the CD standard decided upon after Sony joined forces with the Dutch company would involve 16-bit data words.

Mar 27, 2021 · let me explain: I have an old Philips player that no longer reads CDs so I would like to use its DAC (2xTDA 1540) as a DAC for my system. 2 or 3 selectable inputs (optical and coaxial). possible or impossible? Thanks in advance.

The Philips TDA1540 is the first monolithic bipolar 14-bit DAC with a signal-to-noise ratio of 85 dB (typ) for audio signals, sampled at 44 kHz. It uses a new method of current division, called dynamic element matching, to long-term stability.

Nov 1, 2024 · Does anyone know of a board or other way to transplant these old DAC chips into something that I can connect to a computer, maybe via USB, so they produce an analog signal I can actually amplify?

R2R, RECLOCK, NONOVERSAMLING, all mystery area in the audiophile world are now included in an all-in-one compact PCB! The I2S reclock input circuit in this PCB is based on the Analog Device AN207 stop clock algorithm, left and right channel DAC are latch at the same time.

Mar 27, 2021 · I have an old OMS-5 that's become very unreliable reading CDs and I'd like to try and convert it to a DAC too. Ideally I'd keep it in the original case and use this expanded version of the board that you used for the conversion which should allow direct SPDIF input:
