Voltage Bias. This pin can be used to create an input common-mode DC offset for ADC channel
conversions.
Voltage Reference. Reference voltage for the ADC. An external reference voltage can be connected to
this pin when extremely high accuracy is required.

Analog Input for Common Voltage
Analog Input for Neutral Current
High-Frequency Crystal Input/Output. When using an external high-frequency crystal, the crystal
oscillator circuit should be connected between XTAL1 and XTAL2. When using an externally driven
clock (EXTCLK = 1), the clock should be input at XTAL1, with XTAL2 left unconnected.
Interrupt Request Output. This line is driven low by the device to indicate to the master that an
unmasked interrupt has occurred.
Slave Select Input. This line is the active-low slave select input for the SPI interface.
Slave Clock Input. This line is the clock input for the SPI interface.
Master Out-Slave In Input. This line is used by the master to transmit data to the slave (the
MAXQ3183) over the SPI interface.
Master In-Slave Out Output. This line is used by the MAXQ3183 (the slave) to transmit data back to
the master over the SPI interface.
Pulse Output 1. Configurable to represent energy or RMS voltage or current.
Pulse Output 2. Configurable to represent energy or RMS voltage or current.
Active-Low Reset Input/Output. An external master can reset the MAXQ3183 by driving this pin low.
This pin includes a weak pullup resistor to allow for a combination of wired-OR external reset
sources. An RC circuit is not required for power-up, as this function is provided internally. This pin
also acts as a reset output when the source of the reset is internal to the device (power-fail, watchdog
reset, etc.). In this case, the RESET pin is held low by the device until it exits the reset state, then the
RESET pin is released.
