DESCRIPTION
The PCM3052A is a low-cost, single-chip, 24-bit
stereo
audio
codec
(ADC
single-ended analog voltage input and output. It also
has an analog front end consisting of a 34-dB
microphone amplifier, microphone bias generator, 2
stereo multiplexers, and a wide-range PGA. Analog-
to-digital
converters
(ADCs)
modulation with 64-times oversampling. On the other
hand, digital-to-analog converters (DACs) employ
modulation with 64- and 128-times oversampling.
ADCs include a digital decimation filter with a
high-pass
filter,
and
DACs
oversampling
digital
interpolation
PCM3052A has many functions which are controlled
using the I
2
C interface: DAC digital de-emphasis,
digital attenuation, soft mute etc. The PCM3052A
also has an S/PDIF output pin for the DAC digital
input. The power-down mode, which works on ADCs
and DACs simultaneously, is provided by an external
pin. The PCM3052A is suitable for a wide variety of
cost-sensitive
PC
audio
applications where good performance is required.
The PCM3052A is fabricated using a highly advanced
CMOS process and is available in a small 32-pin
VQFN package.
