Data Sheet - Electrical Characteristics

9. Electrical characteristics are guaranteed from VDD1(MIN) = VDD2(MIN) = VDD3(MIN) to VDD1(MAX) = VDD2(MAX) =

VDD3(MAX). For operations beyond this range, see Typical Operating Characteristics on page 11. For guaranteed

specifications beyond the limits, contact austriamicrosystems, AG.

10. AIN = mid-scale; bit RANGE (page 15) = 1; tested with 20pF on DOUT, 20pF on SSTRB, and fSCLK = 6.4MHz

@ GND to VDD2.

11. SCLK = DIN = GND, CSN = VDD2.

AS1521 Electrical Characteristics

VDD1 = VDD2 = VDD3 = +2.7 to +3.6V, COM = GND, fSCLK = 4.8MHz, 50% duty cycle, 16 clocks/conversion cycle

(300ksps), external +2.5V at REF, REFADJ = VDD1, TAMB = TMIN to TMAX (unless otherwise specified). Typ values at

TAMB = +25ºC.
