Notes: 10. All measurements performed under static conditions.

11. If a crystal is used, then XIN frequency must remain between 2.5 MHz - 5.0 MHz. If an external

oscillator is used, XIN frequency range is 2.5 MHz - 20 MHz, but K must be set so that MCLK is between
2.5 MHz - 5.0 MHz.

12. If external MCLK is used, then the duty cycle must be between 45% and 55% to maintain this

specification.

13. The frequency of CPUCLK is equal to MCLK.

14. The minimum FSCR is limited by the maximum allowed gain register value. The maximum FSCR is

limited by the full-scale signal applied to the channel input.

15. Configuration Register bits PC[6:0] are set to “0000000”.

16. The MODE pin is pulled low by an internal resistor.
