3. Specification is for the parameter over the specified temperature range and is for the CS4373 only and
4. A 2.5 V voltage reference results in the highest dynamic range and best signal-to-noise performance,
5. VREF is defined as {(VREF+) - (VREF-)} and Inputs must satisfy: VA- < VREF- < VREF+ < VA+
6. Power Supply Rejection is tested by applying a 100 mV
7. All outputs unloaded. All digital inputs forced to VD or GND respectively. VA+ = 5 V; VA- = 0;
8. In Low Power Mode LPWR = 1, the Master Clock MCLK is reduced to 1.024 MHz. This reduces the
