CS4340A
18 DS590F2
DC ELECTRICAL CHARACTERISTICS
(AGND = 0 V; all voltages with respect to AGND.)
DIGITAL INTERFACE SPECIFICATIONS
(GND = 0 V; all voltages with respect to GND.)
DIGITAL INPUT CHARACTERISTICS
(AGND = 0 V; all voltages with respect to AGND.)
Notes: 8. Normal operation is defined as RST = HI with a 997 Hz, 0 dBFS input sampled at the highest F
s
for each
speed mode, and open outputs, unless otherwise specified.
9. Power Down Mode is defined as RST = LO with all clocks and data lines held static.
10. Valid with the recommended capacitor values on FILT+ and VQ as shown in Figure 1. Increasing the
capacitance will also increase the PSRR.
