Dual Delta-Sigma Modulator and Encoder

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.

Reference Voltage Input/Output. When APDREF = 0, the buffered internal voltage reference is driven on

this pin as an output and can be used by other devices. When APDREF = 1, an external voltage

reference must be provided on this pin.

Clock Select Input. When CLKSEL = 0, the DS8102 uses its internal 8MHz oscillator as a clock source.

When CLKSEL = 1, the DS8102 operates from an external clock source (which must be provided at

CLKIO).

Gain Select Input 0. This pin, along with G1, is used to select the gain setting for differential analog

input channel 0.

Gain Select Input 1. This pin, along with G0, is used to select the gain setting for differential analog

input channel 0.

Clock Input/Output. When CLKSEL = 0 (internal clock selected), the internal 8MHz clock is output on

this pin and can be used by external devices. When CLKSEL = 1 (external clock selected), an external

clock must be provided on this pin.

Manchester Encoder Output. This output pin provides a Manchester-encoded bit stream containing

output bits from both modulators interleaved with an alternating synchronization bit.

Reset. This input pin can be used to force the DS8102 into a shutdown (low-power) state by driving

RST = 0. If the external reset function is not used, this pin must be connected to V

for proper

operation. An RC circuit is not required on this pin for power-up, as this function is provided internally.

Analog Power-Down Reference. This input pin controls whether the internal voltage reference is

enabled. If APDREF = 0, the internal voltage reference is enabled and the voltage reference level is

driven out on V

. If APDREF = 1, the internal voltage reference is disabled and an external voltage

reference must be provided on V
