Notes

Highest clock frequency at which data slicer produces 1010 output in analog self-test mode.
V
RL
= 0 V, f
sys
= 4.2336 MHz. The maximum input current depends on the value of the external resistor connected
to I
refT:
a) For D1 to D4: I
max
= 2.4/R

Internal reference source with 32 different output voltages. Selection is achieved during a calibration period or via
the serial interface. The values given are for an unloaded V
RH
.
V
RH
= 2.5 V and V
RL
= 0 V, measuring bandwidth: 200 Hz to 20 kHz, f
i(ADC)
= 1 kHz.
f
ripple
= 1 kHz, V
ripple
= 0.5 V (p-p).
Gain of the ADC is defined as G
ADC
= f
sys
/I
max
(counts/
μ
A); thus digital output = I
i
×
G
ADC
where:
a) Digital output = the number of pulses at the digital output in counts/s and I
i
= the DC input current in
μ
A.
b) The maximum input current depends on the system frequency (f
sys
= 4.2336 MHz) and on V
RH
V
RL
.
c) The gain tolerance is the deviation from the calculated gain regarding note 2.
It is recommended that the series resistance of the crystal or ceramic resonator is
≤
60
.
