CS3301A
1. CHARACTERISTICS AND SPECIFICATIONS
• Min / Max characteristics and specifications are guaranteed over the Specified Operating Conditions.
• Typical performance characteristics and specifications are measured at nominal supply voltages and T_A = 25°C.
• GND = 0 V. Single-ended voltages with respect to GND, differential voltages with respect to opposite half.
• Device is connected as shown in Figure 5 on page 12 unless otherwise noted.
