The PCM1780/81/82 is a CMOS, monolithic, inte-
Sampling Frequency: 5 kHz to 200 kHz
grated circuit, which includes stereo digital-to-analog
converters and support circuitry in a small 16-lead
System Clock: 128 fS, 192 fS, 256 fS, 384 fS,
SSOP package. The data converters use TI’s en-
512 fS, 768 fS, 1152 fS With Autodetect
hanced multilevel delta-sigma architecture to achieve
Software Control (PCM1780, PCM1782):
excellent dynamic performance and improved toler-
– Accepts 16-, 18-, 20-, and 24-Bit Audio Data
ance to clock jitter. The PCM1780/81/82 accepts
industry standard audio data formats with 16- to
– Formats: Right-Justified, I
2S, and
24-bit data, providing easy interfacing to audio DSP
Left-Justified
and decoder chips. Sampling rates up to 200 kHz are
– Digital Attenuation: Mode Selectable
supported. The PCM1780/82 provides a full set of
• 0 dB to –63 dB, 0.5 dB/step
user-programmable functions through a three-wire
serial control port, which supports register write
• 0 dB to –100 dB, 1 dB/step
functions. The PCM1781 provides a subset of
– Digital De-Emphasis
user-programmable functions through four control
– Digital Filter Rolloff: Sharp or Slow
pins.
– Soft Mute
The PCM1780 is pin-compatible with the PCM1680
– Zero Flags for Each Output
(8-channel DAC).
– Open-Drain Output Zero Flag (PCM1782)
Hardware Control (PCM1781):
– I
2S and 16-Bit Word, Right-Justified
– Digital De-Emphasis
– Soft Mute
– Zero Flag for L-, R-Channel Common Output
Power Supply: 5-V Single Supply
Small, 16-Lead SSOP Package (150 mil)
Pin-Compatible with PCM1680
