3. PIN DESCRIPTIONS
Control Pins and Serial Data I/O
CS - Chip Select, Pin 4.
CS is a dual function pin, which determines the state of SDO, as well as the digital logic low output
level. When CS is low, SDO will be active. When high, the SDO pin will output a high impedance state.
The logic low level of SDO will match the active low voltage on CS.
SDO - Serial Data Output, Pin 8.
SDO is the serial data output. It will output a high impedance state if CS = 1. The logic low level of SDO
will match the active low voltage on CS.
SCLK - Serial Clock Input, Pin 5.
SCLK is the serial bit-clock which controls the shifting of data from the ADCs. This input goes through a
Schmitt trigger to allow for slow rise and fall time signals. If held high, the device will enter sleep mode.
In the CS5510/12, this input is also used as a master clock source which determines conversion speeds
and throughput. In the CS5511/13, SCLK is only used to read the conversion data and put the part in
sleep mode.
Measurement and Reference Inputs
AIN+, AIN- - Differential Analog Input, Pins 2, 3.
Differential input pins into the device.
VREF - Voltage Reference Input, Pin 1.
Input Voltage which establishes the voltage reference, with respect to V-, for the on-chip modulator.
Power Supply Connections
V+ - Positive Power, Pin 6.
Positive supply voltage.
V- - Negative Supply, Pin 7.
Negative supply voltage.
