CDB5336

16-Bit, Stereo A/D Converters for Digital Audio

Cirrus Logic 

CS5336, CS5338, CS5339

PARAMETER DEFINITIONS

Resolution - The total number of possible output codes is equal to 2N, where N = the number of bits

in the output word for each channel.

Dynamic Range - Full scale (RMS) signal to broadband noise ratio. The broadband noise is measured

over the specified bandwidth, and with an input signal 60dB below full-scale. Units in decibels.

Signal-to-(Noise plus Distortion) Ratio - The ratio of the rms value of the signal to the rms sum of all

other spectral components over the specified bandwidth (typically 10 Hz to 20 kHz), including

distortion components. Expressed in decibels.

Total Harmonic Distortion - The ratio of the rms sum of all harmonics up to 20 kHz to the rms value

of the signal. Units in percent.

Interchannel Phase Deviation - The difference between the left and right channel sampling times.

Interchannel Isolation - A measure of crosstalk between the left and right channels. Measured for

each channel at the converter’s output with the input under test grounded and a full-scale signal

applied to the other channel. Units in decibels.

Interchannel Gain Mismatch - The gain difference between left and right channels. Units in

decibels.

Gain Error - The deviation of the measured full scale amplitude from the ideal full scale amplitude

value.

Gain Drift - The change in gain value with temperature. Units in ppm/°C.

Bipolar Offset Error - The deviation of the mid-scale transition (111...111 to 000...000) from the ideal

(1/2 LSB below AGND). Units in LSBs.
