Caution: Stresses beyond “Absolute Maximum Ratings” levels may cause permanent damage to the device. These levels are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated in Table 3-2, “Recommended Operating

Conditions” is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Table 3-4. Analog Output Characteristics (HV_EN = 1) 1

Test conditions (unless otherwise specified): Fig. 2-1 shows CS43131 connections; input test signal is a 32-bit, full-scale 997-Hz sine wave (unless

specified otherwise); GNDA = GNDCP = GNDD = 0 V; voltages are with respect to ground; HV_EN = 1; ASP_M/Sb = 1; typical, min/max performance

data taken with VA = VCP = 1.8 V; VL = VD = 1.8 V; VP = 3.6 V; TA = +25°C; measurement bandwidth is 20 Hz–20 kHz; ASP_SPRATE = 0001 (LRCK

= 44.1-kHz mode); PDN_XTAL = 0, MCLK_INT = 1, PLUS_1DB = 0, and MCLK_SRC_SEL = 00 (crystal frequency fXTAL = 22.5792 MHz);

Volume = 0 dB; when testing in DSD processor mode, DSD_ZERODB = 1

; when testing noise related specifications (dynamic range, THD+N, idle

channel noise), no external impedance on HPREFx.
