PIN FUNCTIONS
VIN (Pin 1): Analog Input. Connect through a 200Ω
resistor to the analog input. Full-scale input range is
±10V.
AGND1 (Pin 2): Analog Ground. Tie to analog ground
plane.
REF (Pin 3): 2.5V Reference Output. Bypass with 2.2µF
tantalum capacitor. Can be driven with an external refer-
ence.
CAP (Pin 4): Reference Buffer Output. Bypass with 2.2µF
tantalum capacitor.
6
AGND2 (Pin 5): Analog Ground. Tie to analog ground
plane.
D15 to D8 (Pins 6 to 13): Three-State Data Outputs.
Hi-Z state when CS is high or when R/C is low.
DGND (Pin 14): Digital Ground.
D7 to D0 (Pins 15 to 22): Three-State Data Outputs.
Hi-Z state when CS is high or when R/C is low.
BYTE (Pin 23): Byte Select. With BYTE low, data will be
output with Pin 6 (D15) being the MSB and Pin 22 (D0)
being the LSB. With BYTE high the upper eight bits and
the lower eight bits will be switched. The MSB is output
