kept away from the FILT+ and VCOM pins in order to avoid unwanted coupling into the modulators. The
CDB4207 evaluation board demonstrates the optimum layout and power supply arrangements.
QFN Thermal Pad
The CS4207 is available in a compact QFN package. The underside of the QFN package reveals a large
metal pad that serves as a thermal relief to provide for maximum heat dissipation. This pad must mate with
an equally dimensioned copper pad on the PCB and must be electrically connected to ground. A series of
vias should be used to connect this copper pad to one or more larger ground planes on other PCB layers.
In split ground systems, it is recommended that this thermal pad be connected to AGND for best perfor-
mance. The CS4207 evaluation board demonstrates the optimum thermal pad and via configuration.
The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified
bandwidth. Dynamic Range is a signal-to-noise ratio measurement over the specified band width made with
a -60 dBFS signal. 60 dB is added to resulting measurement to refer the measurement to full-scale. This
technique ensures that the distortion components are below the noise level and do not affect the measure-
ment. This measurement technique has been accepted by the Audio Engineering Society, AES17-1991,
and the Electronic Industries Association of Japan, EIAJ CP-307. Expressed in decibels.
The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified
band width (typically 10 Hz to 20 kHz), including distortion components. Expressed in decibels. Measured
at -1 and -20 dBFS as suggested in AES17-1991 Annex A.
A measure of the amplitude response variation from 10 Hz to 20 kHz relative to the amplitude response at
1 kHz. Units in decibels.
A measure of crosstalk between the left and right channel pairs. Measured for each channel at the convert-
er's output with no signal to the input under test and a full-scale signal applied to the other channel. Units in
decibels.
The gain difference between left and right channel pairs. Units in decibels.
The deviation from the nominal full-scale analog output for a full-scale digital input.
The change in gain value with temperature. Units in ppm/°C.
The deviation of the mid-scale transition (111...111 to 000...000) from the ideal. Units in mV.
