NOTES

1These maximum/minimum specifications are guaranteed by characterization to be over the 3.0 V to 3.6 V range.

2Temperature range T

MIN to TMAX: –40

°C to +85°C at 50 MHz and 140 MHz, 0°C to 70°C at 240 MHz and 330 MHz.

3Gain error = {(Measured (FSC)/Ideal (FSC) –1)

× 100}, where Ideal = V

REF /RSET

× K × (3FFH) and K = 7.9896.

4Digital supply is measured with continuous clock with data input corresponding to a ramp pattern and with an input level at 0 V and V

DD.

Specifications subject to change without notice.

(VAA = 3.0 V–3.6 V, VREF = 1.235 V, RSET = 560

, CL = 10 pF. All specifications TMIN to TMAX

2, unless

otherwise noted, TJ MAX = 110 C.)
