FUNCTIONAL DESCRIPTION
The SA9109B is a CMOS mixed signal Analog/Digital integrated circuit, which performs
power calculations across a power range of 1000:1, to an overall accurancy of better than
Class 1. An on-chip LCD driver directly drives a 7 digit (7 segment) LCD display. Also
included on-chip, are 4 tariff registers externally selectable for multi-tariff energy metering
applications and a fifth register which retains the total energy consumption.
The integrated circuit includes all the required functions such as two oversampling A/D
converters for the voltage and current sense inputs, power calculation and energy
integration. Offset is eliminated through the use of internal cancellation procedures.
1.
Power Calculation
In the Application Circuit (Figure 1), the voltage drop across the shunt will be
between 0 and 16mV
RMS (0 to 80A through a shunt resistor of 200µΩ). This voltage
is converted to a current of between 0 and 16µA
RMS, by means of resistors R1 and
R
2.
The current sense input saturates at an input current of ±25µA peak.
The voltage level from the mains is divided down through a divider to 14V.This
voltage is converted to a signal current of 14µA
RMS into the voltage sensor input.
A pulse rate output for calibration purposes is available on SDO (Pin 39), the pulse
rate being proportional to the active energy consumption.
The integrated anti-creep function ensures no metering when no line current is
present.
2.
Analog Input Configuration
The input circuitry of the current and voltage sensor inputs are illustrated below.
These inputs are protected against electrostatic discharge through clamping
diodes.
The feedback loops from the outputs of the amplifiers A
I and AV generate virtual
shorts on the signal inputs. Exact duplications of the input currents are generated
for the analog signal processing circuitry.
