Dual Delta-Sigma Modulator and Encoder  
DS8102  
General Description  
Features  
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.  
♦ Dual Delta-Sigma 2nd-Order Modulators  
Channel 0: Pin-Selectable Gain of 1x, 4x, 16x,  
or 32x  
Channel 1: Fixed Gain of 1x  
♦ Selectable Internal or External Voltage Reference  
♦ Manchester-Encoded Bit Stream Output  
Includes Synchronization Bits to Allow Clock  
Recovery  
Single-Pin Transmission Scheme Simplifies  
Electrical Isolation Using Capacitive Coupling  
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).  
♦ Selectable Internal or External Clock Source  
♦ Integrated Low-Power 8MHz Oscillator  
♦ Operating Mode

= 3.6V): 3.5mA

+Denotes a lead(Pb)-free/RoHS-compliant package.  
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.
