Notes: 1. VDD indicates AVDD and DVDD.
2. AVDD and DVDD must be commonly connected outside the IC. When they are separated by a noise filter, the
potential difference must be 0.3 V or less at power on, and 0.1 V or less during operation.
Electrical Characteristics
(Unless othewide specified, Ta = 25°C, AV_DD = 3.0 V, DV_DD = 3.0 V, and R_BIAS = 33 kΩ)
