PIN TYPE DESCRIPTION
NAME NO.
INPUT
AINP 21 I Positive analog input for ADC A.
AINM 22 I Negative analog input for ADC A.
BINP 60 I Positive analog input for ADC B.
BINM 59 I Negative analog input for ADC B.
CLKP 8 I Positive sampling clock input for ADCs A & B.
CLKM 9 I Negative sampling clock input for ADCs A & B.
VREF 4 I External, 1.6V, voltage reference input.
REFGND 5 I Voltage reference ground. This pin allows close placement of the decoupling capacitors near the VREF input when using either the internal reference or an external reference.
CTRL 6 I This pin is used to configure the default sampling clock type and voltage reference source upon power up (see Section 7.5.1). There is an internal 100kΩ pull-up resistor to AVDD.
PDN/SYNC 3 I Dual purpose, active high, pin. The pin can be configured to control the power down state of the device or as a synchronization input. The pin functionality can be configured via SPI (default function is PDN). This pin has an internal 21kΩ pull-down resistor.
RESET 12 I Active high hardware reset pin. This pin has an internal 21kΩ pull-down resistor.
DCLKINP 39 I Positive input for the interface clock. This pin connects to DCLKINM through an internal 100Ω termination resistor.
DCLKINM 38 I Negative input for the interface clock. This pin connects to DCLKINP through an internal 100Ω termination resistor.
