O
Bypass for an internal bias point. Typically a 0.1
F capacitor minimum is connected from this terminal to ground.
DGND
14, 20
Digital ground
DVDD
18
5-V digital supply
DRVDD
2
3.3-V/5-V digital supply. Supply for digital input and output buffers.
DRGND
13
3.3-V/5-V digital ground. Ground for digital input and output buffers.
D0 –D9
3–12
O
Digital data out. D0:LSB, D9:MSB
OE
16
I
Output enable. When OE = low or NC, the device is in normal operating mode. When OE = high, D0–D9 are high
impedance.
REFBF

25
I
Reference bottom sense
REFTF
22
I
Reference top force
REFTS
21
I
Reference top sense
STBY
17
I
Standby enable. When STBY = low or NC, the device is in normal operating mode. When STBY = high, the device
is in standby mode.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
