Description
Analog Power Ground Pins. Ground reference point for all analog I/O. All analog I/O should be
referenced to AGND and should be connected to the analog ground plane of the system. In addition,
the AGND, DGND, and OGND voltages should be at the same potential.
Analog Power Pins. Nominally 4.75 V to 5.25 V and decoupled with 10 μF and 100 nF capacitors.
Parallel Mode Selection (8-Bit/16-Bit). When high, the LSB is output on D[15:8] and the MSB is output
on D[7:0]; when low, the LSB is output on D[7:0] and the MSB is output on D[15:8].
Straight Binary/Binary Twos Complement Output. When high, the digital output is straight binary.
When low, the MSB is inverted resulting in a twos complement output from its internal shift register.
Conversion Mode Selection. Used in conjunction with the IMPULSE input per the following:
See the Modes of Operation section for a more detailed description.
Conversion Mode Selection. See the WARP pin description in the previous row of this table. See the
Modes of Operation section for a more detailed description.
Serial/Parallel Selection Input.
When SER/PAR = low, the parallel mode is selected.
When SER/PAR = high, the serial modes are selected. Some bits of the data bus are used as a serial port
and the remaining data bits are high impedance outputs.
Bit 0 and Bit 1 of the parallel port data output bus. These pins are always outputs regardless of the
state of SER/PAR.
In parallel mode, these outputs are used as Bit 2 and Bit 3 of the parallel port data output bus.
Serial Data Division Clock Selection. In serial master read after convert mode (SER/PAR = high, EXT/INT
= low, RDC/SDIN = low) these inputs can be used to slow down the internally generated serial data
clock that clocks the data output. In other serial modes, these pins are high impedance outputs.
