wm8199scds-v Wolfson Microelectronics plc, wm8199scds-v Datasheet - Page 7

• Manufacturer Part Number: wm8199scds-v
• Description: 20msps 16-bit Ccd Digitiser
• Manufacturer: Wolfson Microelectronics plc

WM8199
Notes:
Digital supply current depends on the capacitive load connected to the WM8199 output pins and the clock rate applied to
MCLK. This data is based on a load of approximately 10pF per output pin and MCLK = 16MHz.
