3 Characteristics and Specifications

Table 3-7. Serial Data In-to-HPOUTx Characteristics

Test conditions (unless specified otherwise): Fig. 2-1 shows CS43L36 connections; input test signal is a 24-bit full-scale 997-Hz sine wave with 1 LSB of triangular

PDF dither applied; GNDA = GNDL = GNDCP = 0 V; voltages are with respect to ground; parameters can vary with VA; typical performance data taken with VL =

VA = 1.8 V, VP = 3.6 V; min/max performance data taken with VA = 1.66–1.94 V; VL = 1.8 V, VP = 3.6 V; VCP Mode; TA = +25°C; measurement bandwidth is

20 Hz–20 kHz; ASP_LRCK = FsINT = 48-kHz mode; MCLK = 12 MHz, MCLK_SRC_SEL = 0; volume = 0 dB; FULL_SCALE_VOL = 0 (0dB); HP load: RL = 30 

CL = 1 nF (HPOUT_LOAD =0) and RL =3k CL = 10 nF (HPOUT_LOAD = 1)SRC bypassed.

THD+N 2 (defined in Table 3-1)

2.Because VCP settings lower than VA reduce the HP amplifier headroom, the specified THD+N performance at full-scale output voltage and power

may not be achieved.

Turn-on time 6

6.Turn-on time is measured from when the HP_PDN = 0 ACK signal is received to when the signal appears on the HP output. In most cases, enabling

the SRC increases the turn-on time and may exceed the maximum specified value.
