DESCRIPTION
I Serial input in the event monitor mode
I Receiver-path/GP amplifier noninverting input. It needs to be connected to AVSS if not used.
I Receiver-path amplifier A1 inverting input, or inverting input to auxiliary analog input. It needs to be connected to
AVSS if not used. Can also be used for general-purpose amplification.
I Receiver-path amplifier A1 feedback, or noninverting input to auxiliary analog input. It needs to be connected to
AVSS if not used. Can also be used for general-purpose amplification.
I Analog ADC power supply
I Analog ground
DCSI
25
I Direct configuration serial input for directly programming of internal control registers
DIN
17
I Data input. DIN receives the DAC input data and register data from the external digital signal processor (DSP),
and is synchronized to SCLK and FS. Data is latched at the falling edge of SCLK when FS is low. DIN is at high
impedance when FS is not activated.
DOUT
16
O Data output. DOUT transmits the ADC output bits and registers data, and is synchronized to SCLK and FS. Data is
sent out at the rising edge of SCLK when FS is low. DOUT is at high impedance when FS is not activated.
