CS3302A
1. CHARACTERISTICS AND SPECIFICATIONS
• Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions.
• Typical performance characteristics and specifications are derived from measurements taken at nom-
inal supply voltages and T_A = 25°C.
• GND = 0 V, all voltages with respect to 0 V.
• Device connected as shown in Figure 5 on page 12 unless otherwise noted.
