... ADC conversion data by reading the Si890x serial port. Devices in this series differ only in the type of serial port. Options include a UART with on-chip baud rate generator that operates at 234 kbps max (Si8900), an SMBus/I port that operates at 240 kbps max (Si8901), and an SPI Port that operates at 2.5 MHz max (Si8902). ...

... C/SMBus Slave Address byte (Si8901 Slave Address is 0xF0). The Si8902 Demand Mode ADC read transaction (Figure 5C) is the same as that of the Si8900, except the master must wait 8 µs after the transmission of the Command Byte before reading the Si8902 SPI port because byte transmission time is two times shorter versus the Si8900/01 ...
Page 12
... The Burst Mode ADC transactions for the Si8900 (Figure 6A) and Si8901 (Figure 6B) are substantially the same. A Burst Mode ADC read is initiated when the master writes a CNFG_0 (MODE = 0) Command Byte to the Si8900/1, which updates the CNFG_0 register and triggers the ADC continuously. Like the Demand Mode example, the Si8901 has a Slave Address byte prior to the CNFG_0 Command Byte ...

... There are a total of 10 bits per data read/write: One start bit, eight data bits (LSB first), and one stop bit with data transmitted LSB first as shown in Figure 7. Figure 8A and Figure 8B show master/Si8900 ADC read transactions for Demand Mode and Burst Mode, respectively. ...

... Si8900/1/2 6. Applications 6.1. Isolated Outputs The Si890x serial outputs are internally isolated from the device input side. To ensure safety in the end-user application, high voltage circuits (i.e., circuits with >30 VAC) must be physically separated from the safety extra-low voltage circuits (i.e., circuits with <30 VAC certain distance (creepage/clearance component straddles this isolation barrier, it must meet those creepage/clearance requirements and also provide a sufficiently large high-voltage breakdown protection rating (commonly referred to as working voltage protection) ...

... Si8900/1/2 6.3. Application Example Figure 17 shows the Si8900 operating as a single-phase ac line voltage and current monitor. The VDDA dc bias circuit uses a low-cost 3.3 V linear regulator referenced to the neutral (white wire). The ac current is measured on ADC input AIN0. The ac line voltage is scaled by resistors R17 and R18 and level-shifted by the 1.5 V VREF. AC line current is measured using differential amplifier U1 connected across shunt resistor R1 ...
