DC CHARACTERISTICS
Tamb = 40 to 85 °C; VDD =VDDD =VDDA; VSS =VSSD =VSSA = 0 V; unless otherwise specied.
Notes
1. In power down mode this input is inactive and switched to ground with more than 40 k
. An AC coupling with 33 pF
is recommended.
2. The voltage at pin VS2 = VSR Vd1 with the forward voltage Vd1 ~ 250 mV of the DC reference diode D1 of the RF
sensor. Vd1 must not be influenced by RF because a voltage change at pin VS2 moves the input voltage of the adder
and slope generator.
3. Two 1 k
resistors close to the RF sensor diode D2 in the block diagram are necessary for RF decoupling.
4. The necessary start-up time TON = 400 s (see Fig.3) between PD and TRIG is more than Tpd.
