Analog ground pins. AGND must be shorted to analog ground plane below the device.
Digital ground for all digital inputs and outputs. BDGND must be shorted to the analog ground plane
below the device.
Status output. This pin is high when conversion is in progress.
Convert start. This signal is qualified with CS internally.
Chip select
Frame sync. This signal is qualified with CS internally.
Noninverting analog input channel
Inverting analog input channel
No connection
Power down. Device resets and powers down when this signal is high.
Reference (positive) input. REFIN must be decoupled with REFM pin using 0.1-
μ
F bypass capacitor
and 1-
μ
F storage capacitor.
Reference ground. To be connected to analog ground plane.
Internal reference output. Shorted to REFIN pin only when internal reference is used.
Straight binary or 2's complement output data format. When low the device output is straight binary
format; when high the device output is 2's complement format. See
Table 1
.
Serial clock. Data is shifted onto SDO with the rising edge of this clock. This signal is qualified with CS
internally.
Serial data out. All bits except MSB are shifted out at the rising edge of SCLK.
Analog power supplies
Digital power supply for all digital inputs and outputs.
