4 Characteristics & Specifications
Unless otherwise noted: AVDD=2.9..3.6V, DVDD=2.5..3.6V, TA=-30..+85^◦C, XTALI=24.576MHz, Full-
Scale Output Sinewave at 1.526 kHz, measurement bandwidth 20..20000 Hz, analog output load 30Ω (no
ground buffer) or 100Ω (with ground buffer), bitstream 128 kbit/s, local components as shown in Fig-
ure 3.
Note, that some analog values are in practice better than in these tables if chips are used within a limited
temperature range and not too close to lower voltage limits.
