Description
On-Chip 2.5 V Analog Low Dropout (LDO) Regulator Access. Do not connect external active circuitry to this
pin. Decouple this pin with a 4.7 μF capacitor in parallel with a ceramic 220 nF capacitor.
Ground Reference. This pin provides the ground reference for the analog circuitry. Tie this pin to the analog
ground plane or to the quietest ground reference in the system. Use this quiet ground reference for all
analog circuitry, such as antialiasing filters and current and voltage transducers.
Supply Voltage. This pin provides the supply voltage and should be set at 3.3 V ± 10% for specified operation.
Decouple this pin to AGND with a 10 μF capacitor in parallel with a ceramic 100 nF capacitor.
Master Clock. An external clock can be provided at this logic input. Alternatively, a parallel resonant AT-cut
crystal can be connected across CLKIN and CLKOUT to provide a clock source for the ADE7816. The clock
frequency for specified operation is 16.384 MHz. Use ceramic load capacitors of a few tens of picofarads (pF)
with the gate oscillator circuit. Refer to the crystal manufacturer data sheet for load capacitance requirements.
A crystal can be connected across this pin and CLKIN (as stated in the description for Pin 27) to provide
a clock source for the ADE7816. The CLKOUT pin can drive one CMOS load when either an external clock
is supplied at CLKIN or a crystal is being used.
Interrupt Request Outputs. These are active low logic outputs. See the Communication section for a detailed
presentation of the events that can trigger interrupts.
Serial Clock Output for the HSDC Port.
Serial Clock Input for the SPI Port/Serial Clock Input for the I2C Port. All serial data transfers are synchronized to
this clock (see the Serial Interfaces section). This pin has a Schmidt trigger input for use with a clock source
that has a slow edge transition time (for example, opto-isolator outputs).
Data Output for SPI Port/Data Output for HSDC Port.
Data Input for SPI Port/Data Output for I2C Port.
Slave Select for SPI Port/HSDC Port Active.
Exposed Pad. Create a similar pad on the PCB under the exposed pad. Solder the exposed pad to the pad on
the PCB to confer mechanical strength to the package. Do not connect the pads to AGND.
