16-BIT, SIGMA-DELTA ANALOG-TO-DIGITAL CONVERTERS
The ADuC7039 incorporates two independent sigma-delta
(Σ-Δ) analog-to-digital converters (ADCs) namely, the current
channel ADC (I-ADC), and the voltage/temperature channel
ADC (V/T-ADC). These precision measurement channels
integrate attenuator, on-chip buffering, a programmable gain
amplifier, 16-bit, Σ-Δ modulators, and digital filtering for
precise measurement of current, voltage, and temperature
variables in 12 V automotive battery systems.
Current Channel ADC (I-ADC)
The I-ADC converts battery current sensed through an external
100 μ shunt resistor. On-chip programmable gain means that
the I-ADC can be configured to accommodate battery current
levels from up to ±1500 A.
As shown in Figure 11, the I-ADC employs a Σ-Δ conversion
technique to realize 16 bits of no missing codes performance.
The Σ-Δ modulator converts the sampled input signal into a
digital pulse train whose duty cycle contains the digital infor-
mation. A modified sinc3, programmable, low-pass filter is then
employed to decimate the modulator output data stream to give
a valid 16-bit data conversion result at programmable output
rates from 10 Hz to 1 kHz in normal and low power mode.
The I-ADC also incorporates a counter, comparator, and
accumulator logic. This allows the I-ADC result to generate an
interrupt after a predefined number of conversions have elapsed
or if the I-ADC result exceeds a programmable threshold value.
Once enabled, a 32-bit accumulator automatically sums the
16-bit I-ADC results.
The time to a first valid (fully settled) result on the current
channel is three ADC conversion cycles with chop mode turned
off and two ADC conversion cycles with chop mode turned on.
An interrupt can be generated even on unsettled ADC samples
by enabling the ADC continuous interrupt option.
