Standby Mode (Oscillator active, allows quick power-up).
Sleep Mode (Oscillator inactive).
Normal Mode
Activate the power save select mode.
Normal Operation.
Activate a Reset cycle. See System Reset Sequence in the datasheet text.
Normal Operation
System was reset. This bit is read only. Bit is cleared to logic zero after the configuration register is read.
Normal Input
All signal input pairs for each channel are disconnected from the pins and shorted internally.
Normal Operation of A0 as an output latch.
A0’s output is modified to output the common mode output voltage of the instrumentation amplifier (typically
2.5 V). The output latch select bit is ignored when the guard buffer is activated.
2.5 V < V
1 V
The latch bits (A0 and A1) will be set to the logic state of these bits upon command word execution if the output
latch select bit (OLS) is set. Note that these logic outputs are powered from VA+ and VA-.
A0 = 0, A1 = 0
A0 = 0, A1 = 1
A0 = 1, A1 = 0
A0 = 1, A1 = 1
When low, uses the Channel-Setup Register as the source of A1 and A0.
When set, uses the Configuration Register as the source of A1 and A0.
Must always be logic 0. Reserved for future upgrades.
Calibration registers used are based on the CS1-CS0 bits of the referenced Setup.
Calibration registers used are based on the OG1-OG0 bits of the referenced Setup.
