Alternatively, an external (CMOScompatible) clock (powered relative to VD+) can be supplied into the OSC2 pin to provide themaster clock for the device.Control Pins and Serial Data I/OCS - Chip Select.When active low, the port will recognize SCLK. When high the SDO pin will output a highimpedance state. CS should be changed when SCLK = 0.46 DS289PP5
CS5531/32/33/34SDI - Serial Data Input.SDI is the input pin of the serial input port. Data will be input at a rate determined by SCLK.SDO - Serial Data Output.SDO is the serial data output. It will output a high impedance state if CS =1.SCLK - Serial Clock Input.A clock signal on this pin determines the input/output rate of the data for the SDI/SDO pinsrespectively. This input is a Schmitt trigger to allow for slow rise time signals. The SCLK pinwill recognize clocks only when CS is low.A0 - Logic Output (Analog)/Guard, A1 - Logic Output (Analog).The logic states of A1-A0 mimic the OL1-OL0 bits in the selected Setup, or the A1-A0 bits inthe Configuration Register, depending on the state of the OLS bit in the Configuration Register.Logic Output 0 = VA-, and Logic Output 1 = VA+. Alternately, A0 can be used as a guarddrive for the instrumentation amplifier with proper setting of the GB bit in the ConfigurationRegister.Measurement and Reference InputsAIN1+, AIN1-, AIN2+, AIN2- AIN3+, AIN3-, AIN4+, AIN4- - Differential Analog Input.Differential input pins into the device.VREF+, VREF- - Voltage Reference Input.Fully differential inputs which establish the voltage reference for the on-chip modulator.C1, C2 - Amplifier Capacitor Inputs.Connections for the instrumentation amplifier’s capacitor.Power Supply ConnectionsVA+ - Positive Analog Power.Positive analog supply voltage.VD+ - Positive Digital Power.Positive digital supply voltage (nominally +3.0 V or +5 V).VA- - Negative Analog Power.Negative analog supply voltage.DGND - Digital Ground.Digital Ground.DS289PP5 47
