Notes:
1. Typical and not directly tested. Verified on initial part evaluation.
2. Each part is tested at 85 deg C for the given specification.
3. The chip may not operate properly at clock frequencies below MIN and above MAX.
4. Capacitive output load is 20pf. Delays are measured from the rising edge of the clock to the output level rising
above V_IH or Falling below V_IL.
5. The minimum clock rate must satisfy F_CK/(4N) > 1KHz.
6. Capacitive output load is 80pf.
7. Current changes linearly with voltage and clock speed:
Icc (MAX)
=
^{V---3-C--.--3-C---}_5-^F--0--C--_M^-K--


31 + A_29 + ^3---N2---0--_
mA
where A is the number of active channels (0 to 4) and N is the CIC decimation ratio.
8. See timing diagram in Figure 2 and description in Section 3.1.
