The PCM3052A is a low-cost, single-chip, 24-bit
stereo
audio
codec
(ADC
and
DAC)
with
– On-Chip High-Pass Filter: 0.91 Hz at
single-ended analog voltage input and output. It also
fS = 48 kHz
has an analog front end consisting of a 34-dB
– High Performance:
microphone amplifier, microphone bias generator, 2
THD+N: –94 dB (Typical)
stereo multiplexers, and a wide-range PGA. Analog-
to-digital
converters
(ADCs)
employ
delta-sigma
SNR: 101 dB (Typical)
modulation with 64-times oversampling. On the other
Dynamic Range: 101 dB (Typical)
hand, digital-to-analog converters (DACs) employ
Stereo DAC:
modulation with 64- and 128-times oversampling.
ADCs include a digital decimation filter with a
– Single-Ended Voltage Output: 4 Vp-p
high-pass
filter,
and
DACs
include
an
8-times
– Analog Low-Pass Filter Included

filter.
The
–
×8 Oversampling Digital Filter:
PCM3052A has many functions which are controlled
Pass-Band Ripple: ±0.03 dB
using the I2C interface: DAC digital de-emphasis,
digital attenuation, soft mute etc. The PCM3052A
Stop-Band Attenuation: –50 dB
also has an S/PDIF output pin for the DAC digital
– High Performance:
input. The power-down mode, which works on ADCs
THD+N: –97 dB (Typical)
and DACs simultaneously, is provided by an external
pin. The PCM3052A is suitable for a wide variety of
SNR: 105 dB (Typical)
cost-sensitive
PC
audio
(recorder
and
player)
Dynamic Range: 104 dB (Typical)
applications where good performance is required.
S/PDIF Output for DAC Digital Input
The PCM3052A is fabricated using a highly advanced
A
CMOS process and is available in a small 32-pin
VQFN package.
