DESCRIPTION
The PCM1804-Q1 device is a high-performance,
single-chip stereo A/D converter with fully differential
analog voltage input which uses a precision delta-
sigma modulator and includes a linear-phase antialias
digital filter and high-pass filter (HPF) that removes
DC offset from the input signal. The PCM1804-Q1
device is suitable for a wide variety of mid- to high-
grade consumer and professional applications, where
excellent performance and 5-V analog supply and
3.3-V digital power-supply operation are required.
The PCM1804-Q1 device can achieve both PCM
audio and DSD format due to the precision delta-
sigma modulator. The PCM1804-Q1 device is
fabricated using an advanced CMOS process and is
available in a small 28-pin SSOP package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
