CS42L55
ANALOG PASSTHROUGH CHARACTERISTICS
Test Conditions (unless otherwise specified): Connections to the CS42L55 are shown in the “Typical Connection Diagram” on
page 10; Input is a 1 kHz sine wave through the passive input filter shown in Figure 1, PGA and HP/Line gain = 0 dB; All Sup-
plies = VA, VCP Mode; GND = AGND = 0 V; TA = +25 °C; Measurement bandwidth is 20 Hz to 20 kHz. Sample Frequency =
48 kHz.
COMBINED DAC INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE
Notes:
15. Response is clock dependent and will scale with Fs. Note that the response plots (Figures 31 to 34 on
page 70) have been normalized to Fs and can be de-normalized by multiplying the X-axis scale by Fs.
16. Measurement bandwidth is from Stopband to 3 Fs.
VA = 2.5 V
VA = 1.8 V
