CS42L56
ANALOG PASSTHROUGH CHARACTERISTICS
Test Conditions (unless otherwise specified): Connections to the CS42L56 are shown in the “Typical Connection Diagrams” on
page 11; Input test signal is a 1 kHz sine wave through the passive input filter shown in Figure 1, PGA and HP/Line gain = 0 dB;
All Supplies = VA, VCP Mode; GND = AGND = 0 V; T
A
= +25C; Measurement bandwidth is 20 Hz to 20 kHz; Sample Fre-
quency = 48 kHz; Measurement signal path is AINxx to HPOUTx or LINEOUTx.
