Sample Clock Reset
(Input): LVDS - A positive differential pulse on these
pins is used to reset and synchronize the ADC
sample clock when multiple ADCs are used. See 1.5
MULTIPLE ADC SYNCHRONIZATION. When bit 14
in the Configuration Register (address 1h) is set to
1b, these differential ADCCLK_RST± pins are
selected. See description for pin 15.
Common Mode Voltage
(Output): ANALOG - The voltage output at this pin
is required to be the common mode input voltage at
V
should be grounded when a.c. coupling is used at
the analog input. This pin is capable of sourcing or
sinking 100μA and can drive a load up to 80 pF. See
Section 2.2 THE ANALOG INPUT.
Bandgap Output Voltage
(Output): Analog - Capable of 100 μA source/sink
and can drive a load up to 80 pF.
Calibration Running
(Output): LVCMOS - This pin is at a logic high while
a calibration is running.
External Bias Resistor Connection
Analog - Nominal value is 3.3k-Ohms (±0.1%) to
ground. See Section 1.1.1 Calibration.
Temperature Diode
Analog - Positive (Anode) and Negative (Cathode).
These pins may be used for die temperature
measurements, however no specified accuracy is
implied or guaranteed. See Section 2.6.2 Thermal
Management.
