Four analog input channels.
Analog input shielding grounds, not internally con-
nected. Connect each to external low-impedance
ground as close to device as possible.
One of two TTL decode control lines required for
channel selection. See Logic Truth Table.
One of two TTL decode control lines required for
channel selection. See Logic Truth Table.
TTL-compatible chip enable. In enabled mode
(logic HIGH), output signal tracks selected input
channel; in disabled mode (logic LOW), output is
high impedance and no signal appears at output.
Negative supply voltage; normally –10 V dc to
–15 V dc.
Positive supply voltage; normally +10 V dc to
+15 V dc.
Analog output. Tracks selected input channel when
enabled.
Bypass terminal for internal bias line; must be
decoupled externally to ground through 0.1 F
capacitor.
Analog signal and power supply ground return.
