General Description
The DS8102 is a stand-alone, dual-channel, delta-
sigma modulator that converts measurements from two
differential analog input pairs into a Manchester-encod-
ed output bit stream that can be processed by a com-
panion microcontroller such as the MAXQ3108. One
channel operates at a fixed 1x gain, while the other
operates at a pin-selectable gain of 1x, 4x, 16x, or 32x.
The DS8102 includes an internal power-supply monitor,
on-board voltage reference, and low-power oscillator to
reduce the number of external components required for
data acquisition.
The Manchester-encoded output from the DS8102
combines pulse-density-modulated measurement val-
ues from both differential input channels with a syn-
chronization bit stream and is transmitted over a single
pin. This transmission scheme is ideal for split voltage
domain applications where the DS8102 and other “hot”-
side components must be electrically isolated from
“cold” low-voltage components such as a companion
microcontroller. In this type of application, the DS8102
can be capacitively coupled to a companion microcon-
troller with only two connection points required
(MNOUT and DGND).
The MAXQ3108 dual-core microcontroller, which
includes specialized Manchester bit-stream decoding
inputs and sinc3 filters, is specifically designed to act
as a companion microcontroller for up to three DS8102
devices. This configuration, which supports up to six
differential analog input channels, is well suited for
three-phase electricity-metering applications.
