Colinear ^™20-Bit Monolithic Audio

DIGITAL-TO-ANALOG CONVERTER

FEATURES

DESCRIPTION

● COLINEAR 20-BIT AUDIO DAC

● NEAR-IDEAL LOW LEVEL OPERATION

● GLITCH-FREE OUTPUT

The PCM63P is a precision 20-bit digital-to-analog

converter with ultra-low distortion (–96dB max with a

full scale output; PCM63P-K). Incorporated into the

PCM63P is a unique Colinear dual-DAC per channel

architecture that eliminates unwanted glitches and

other nonlinearities around bipolar zero. The PCM63P

also features a very low noise (116dB max SNR;

A-weighted method) and fast settling current output

(200ns typ, 2mA step) which is capable of 16-times

oversampling rates.

● ULTRA LOW –96dB max THD+N

(Without External Adjustment)

● 116dB SNR min (A-Weight Method)

● INDUSTRY STD SERIAL INPUT FORMAT

● FAST (200ns) CURRENT OUTPUT

(±2mA; ±2% max)

Applications include very low distortion frequency

synthesis and high-end consumer and professional

digital audio applications.

● CAPABLE OF 16x OVERSAMPLING

● COMPLETE WITH REFERENCE
