NAME
FUNCTION
Positive Charge-Pump Output. Bypass V_P to GND with a 10nF, 50V capacitor for applications with an
1
V_P
input range of ±15V (SEL35 = low) or a 100V capacitor for applications with an input range of -15V/+35V
(SEL 35 = high). Place the capacitor as close as possible to the device.
2
GND Ground
3
V_N
Negative Charge-Pump Output. Bypass V_N to GND with a 50V, 10nF ceramic capacitor placed as close
as possible to the device.
4
V_CC
Power-Supply Input. Bypass V_CC to GND with a 1μF ceramic capacitor placed as close as possible to the
device.
5
I.C.
Internally Connected. Connect to GND.
6
A1
Analog Switch 1 Terminal A. Switch 1 is open when EN1 is low.
7
A2
Analog Switch 2 Terminal A. Switch 2 is open when EN2 is low.
8
A3
Analog Switch 3 Terminal A. Switch 3 is open when EN3 is low.
9
A4
Analog Switch 4 Terminal A. Switch 4 is open when EN4 is low.
10
SEL35
Analog-Signal Range Select Input. Drive SEL35 low to enable the -15V/+15V analog signal range. Drive
SEL35 high to enable the -15V/+35V analog signal range.
11
EN1
Switch 1 Control Input. Drive EN1 high to close switch 1. Drive EN1 low to open switch 1.
