... The CS5466 is a low-cost power meter solution incorpo- rating dual delta-sigma (∆Σ) analog-to-digital converters (ADCs), an energy-to-frequency converter, and energy pulse outputs on a single chip. The CS5466 is designed to accurately measure and calculate energy for single phase 3-wire power metering applications with minimal external components ...

... VA+/AGND, both of the CS5466’s input channels accommodate common-mode plus signal levels be- tween (AGND - 0.25 V) and VA+. The CS5466 has three pulse output pins: E1, E2, and FOUT. E1 and E2 can be used to directly drive a mechanical counter or stepper motor, or interface to a microcontroller. The FOUT pin conveys active (real) power at a pulse fre- quency many times higher than that of the pulse frequency, allowing for high-speed calibration ...

... Hz) is imposed onto the +5 V supply voltage at VA+ and VD+ pins. The “+” and “-” input pins of both input channels are shorted to VA-. Then the CS5466 is put into an internal test mode and digital output data is collected for the channel under test. The zero-peak value of the digital sinusoidal output signal is determined, and this value is converted into the zero-peak value of the sinusoidal voltage that would need to be applied at the channel’ ...

... Modulator Voltage Channel 4. THEORY OF OPERATION The CS5466 is a dual-channel analog-to-digital convert- er (ADC) followed by a computation engine that per- forms an energy-to-pulse conversion. The flow diagram for the two data paths is depicted in Figure 2. The ana- log inputs are structured with two dedicated channels, voltage and current, then optimized to simplify interfac- ing to sensing elements ...

... HPF is enabled in the current channel when pin HPF is connected to pin FOUT. 5.3 Energy Pulse Outputs The CS5466 provides three output pins for energy reg- istration. The E1 and E2 pins provide a simple interface from which energy can be registered. These pins are designed to directly connect to a stepper motor or elec- tromechanical counter ...

... FREQ max until the analog voltage reaches 4 that time eight-XIN-clock-period delay is enabled to allow the os- cillator to stabilize. The CS5466 will then initialize. The device reads the control pins IGAIN[1:0], FREQ[2:0] and HPF, and begins performing energy measure- ments. 5.6 Oscillator Characteristics ...
