fosc=0.45/RC; Cosc>50pF; Rosc>50kΩ; fosc(Typ)=48kHz
tosc=RC/0.45
Fclock=fosc/4
tINT=1000x(4/fosc)
tINT/ t60Hz or tINT/ t50Hz=Integer
IINT=4µA
VINFS(Typ)=200mV or 2V
RINT=VINFS/IINT
CINT=(tINT) (IINT)/VINT
VINT=(tINT) (IINT)/CINT
(V-+0.5V)<VINT<(V+-0.5V), VINT(Typ)=2V
COUNT=1000x (VIN/VREF)
tCYC=tCLOCKx4000; tCYC=toscx16000;
when fosc=48kHz; tCYC=333ms
(V-+1V)<VIN<(V+-0.5V)
0.01µF<CAZ<1µF
0. 1µF<CREF<1µF
Biased between Vi and V-
Regulation lost when V+ to V-<≈6.8V ;if VCOM is externally pulled
down to (V+ to V-)/2, the VCOM circuit will turn off.
V+ to V-=9V, digital supply is generated internally,
VGND≈V+−4.5V
Type: Direct drive with digital logic supply amplitude.
V+=+5V TO GND, V-=-5V TO GND, Digital Logic and LED driver
supply V+ to GND
Type: Non-Multiplexed Common Anode
