Buffer Outputs. Buffer inputs are internally grounded with
a 1000 or 1001 command from the D3–D0 lines.
Analog Ground. AGND must be at 0.0V, since the gain-
setting resistors of the buffers are connected to these
pins.
Parallel Data Bit when SER/PAR = GND. When
D3 = GND, D0–D2 specify the input channel to be con-
nected to specified buffer. When D3 = V
specify control codes. D3 is not used in serial mode
(SER/PAR = V
Parallel Data Bit D2 when SER/PAR = GND. Not used
when SER/PAR = V
Positive Supply. All V+ pins must be connected to each
other and bypassed to AGND separately (Figure 2).
