Table 3-10. Power Consumption

Test conditions (unless specified otherwise): Fig. 2-1 shows CS43L36 connections; GNDA = GNDL = GNDCP = 0 V; voltages are with respect to ground;

performance data taken with VA = VCP = VL = 1.8 V; DIGLDO_PDN is deasserted; VP = 3.6 V; TA = +25°C; ASP_LRCK = 48-kHz Mode; FsINT = 48 kHz;

SCLK = 12 MHz, MCLK_SRC_SEL = 0; volume= 0 dB; FULL_SCALE_VOL = 1 (–6 dB) for HPOUTx, TIP_SENSE_CTRL = 11, all other fields are set to

defaults; no signal on any input; control port inactive; input clock/data are held low when not required; test load is RL = 30  and CL = 1 nF for HPOUTx;

measured values include currents consumed by the DAC and do not include current delivered to external loads unless specified otherwise (e.g., HPOUTx);

see Fig. 3-1.

VCP/3

Note: The current draw on the VA, VCP, and VL

power supply pins is derived from the measured

voltage drop across a 10-

 series resistor between

the associated supply source and each voltage

supply pin. Given the larger currents that are

possible on the VP supply, an ammeter is used for

the measurement.
