Preliminary Technical Data
ADuC7032
Rev. PrD | Page 46 of 128
VOLTAGE CHANNEL ADC (V-ADC)
This ADC is intended to convert battery voltage As with the
Current Channel ADC described previously, this ADC employs
an identical sigma-delta conversion technique, including a
modified Sinc3 low-pass filter to give a valid 16-Bit data
conversion result at programmable output rates from 4Hz to 8
KHz. An external RC filter network is not required as this is
implemented internally in the voltage channel.
The external battery voltage (VBAT) is routed to the ADC
input via an on-chip high voltage, resistive attenuator This
must be enabled/disabled via HVCFG1[7].
The time to a first valid (fully settled) result on the voltage
channel is three ADC conversion cycles with chop mode turned
off and two ADC conversion cycles with chop mode turned on.
This ADC is again buffered but unlike the current channel has
a fixed VBAT input range of 0 V to 28.8V (assuming an
internal 1.2V reference). A top level overview of this ADC
signal chain is shown in Figure 16 below.
TEMPERATURE CHANNEL ADC (T-ADC)
This ADC is intended to convert battery temperature. The
battery temperature can be derived via the on-chip temperature
sensor or an external temperature sensor input.
The time to a first valid (fully settled) result after an input
channel switch on the temperature channel is three ADC
conversion cycles with chop mode turned off and two ADC
conversion cycles with chop mode turned on.
As with the Current and Voltage Channel ADCs, this ADC
employs an identical sigma-delta conversion technique,
including a modified Sinc3 low-pass filter to give a valid 16-Bit
data conversion result at programmable output rates from 4Hz
to 8 KHz
