CS43L36

3 Characteristics and Specifications

Table 3-14. Digital Interface Specifications and Characteristics

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

parameters can vary with VL and VP; min/max performance data taken with VCP = VA = 1.8 V, VD_FILT = 1.2 V; VP = 3.0–5.25 V; VL = 1.66–1.94 V

(VL_SEL = VP) or VL = 1.1–1.3 V (VL_SEL = GNDD); TA = +25°C; CL =60pF.
