DACO
Decrease VBAT until internal switch
between VBAT and VDD becomes high
ohmic (“off”)
Increase VBAT until internal switch
between VBAT and VDD becomes low
ohmic (“on”)
Difference between on and off threshold
DA[6:0] = 127, RBAT = 1
DA[6:0] = 27, RBAT = 1
DA[6:0] = 127, RBAT = 0
DA[6:0] = 0, RBAT = 0
VCOIN = 20 dB less than G.R.L.
VCOIN = 40 dB less than G.R.L.
VCOIN = 50 dB less than G.R.L.
VCOIN = 60 dB less than G.R.L
VCOIN = step 31.6 mV –> 126 mV,
(-30 dBV –> –18 dBV)
measure time after step, when output
voltage has 1.5 times of final value
