NOTES

1Operating temperature ranges as follows: A Version: –40

°C to +85°C; J Version: 0°C to +70°C.

2All dynamic specifications are measured using IOUT. 100% Production tested.

CLK = 6.25 MHz, Frequency Word = 5671C71C HEX, f OUT = 2.11 MHz.

REF may be externally driven between 0 and V DD.

5Do not allow reference current to cause power dissipation beyond the limit of I

AA + IDD shown above.

Specifications subject to change without notice.
