DC ELECTRICAL CHARACTERISTICS
16. Normal operation is defined as RST pin = High with a 997 Hz, 0 dBFS input sampled at the highest Fs for
each speed mode, and open outputs, unless otherwise specified.
17. I
A
measured with no loading on the AMUTEC and BMUTEC pins.
18. I
LC
measured with no external loading on pin 11 (SDA).
19. Power-Down mode is defined as RST pin = Low with all clock and data lines held static.
20. Valid with the recommended capacitor values on FILT+ and V
Q
as shown in the “Typical Connection Dia-
gram” on page 19.
21. This current is sourced/sinked directly from the VA supply.
