ELECTRICAL CHARACTERISTICS

All parameters are specified at TA = +25°C with VCC = +5V, VDD = +3.3V, and a measurement bandwidth from 20Hz to 20kHz, unless otherwise

noted. System clock frequency is equal to 256fS for Single and Dual Rate sampling modes, and 128fS for Quad Rate sampling mode.

(1) Applies to the RST input, pin 19.

(2) Single, Dual, and Quad Rate sampling modes are described within this data sheet.

(3) Dynamic performance parameters are measured using an Audio Precision System Two Cascade or Cascade Plus test system. The

measurement bandwidth is limited by using the Audio Precision 22Hz high-pass filter in combination with the Audio Precision 20kHz, fS/2, or

a user-defined 40kHz low-pass filter. All A-weighted measurements are performed using the Audio Precision A-weighting filter in combination

with the previously mentioned filters.
