Voltage/Temperature Channel ADC (V/T-ADC)
The voltage/temperature channel ADC (V/T-ADC) converts
additional battery parameters such as voltage and temperature.
The input to this channel can be multiplexed from an external
voltage and an on-chip temperature sensor.
As with the current channel ADC described previously, the
V/T-ADC employs an identical Σ-Δ conversion technique,
including a modified sinc3 low-pass filter to give a valid
16-bit data conversion result at programmable output rates
from 10 Hz to 1 kHz. An external RC filter network is not
required because this is internally implemented in the
voltage channel.
The external battery voltage (VBAT) is routed to the ADC input
via an on-chip, high voltage (divide-by-24), resistive attenuator.
This ADC channel, unlike the current channel, has a fixed input
range of 0 V to 28.8 V on VBAT.
The battery temperature can be derived through the on-chip
temperature sensor.
By default, the time to a first valid (fully settled) result after
an input channel switch on the voltage/temperature channel
is three ADC conversion cycles with chop mode turned off.
A top level overview of the ADC signal chain is shown in
