CS3302
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 nomi-
nal supply voltages and T_A = 25°C.
• DGND = 0 V, all voltages with respect to 0 V.

Notes: 1. VA- must be the most negative voltage to avoid potential SCR latch-up conditions.
2. VD must conform to Digital Supply Differential under Absolute Maximum Ratings.
