DAC Uses 2.1 Vrms Line Driver
Allowing a 2 Vrms voltage after the RC filter, Cirrus Logic’s CS4252 24-bit DAC utilizes an on-chip 2.1 Vrms line driver from a single 3.3 V power supply. The 24-pin QFN-packaged unit exhibits 24-bit conversion, audio sampling rates up to 192 kHz, 106 dB dynamic range, and -93 dB THD+N. The converter performs in consumer electronics, such as set-top boxes, Blu-ray disc players, game consoles, and digital TVs, as well as effects processors, musical instruments, digital audio recorders, and automotive audio systems. The component allows for the removal of external DC blocking capacitors and pop prevention circuitry, and is based on ground-centered output, fifth-order multibit Delta Sigma converter architecture. Pricing is $1.28 in 10,000 quantities.
