I/O
DESCRIPTION
AIN
26
I
Analog input
AVDD
16, 27
I
Analog supply voltage
AVSS
18, 23, 28
I
Analog ground
BG
17
O
Band gap reference voltage. A 1-
F capacitor (with an optional 0.1-F capacitor in parallel) should be
connected between this terminal and AVSS for external filtering.
CLK
12
I
Clock input. The input is sampled on each rising edge of CLK.
CML
25
O
Common mode level. This voltage is equal to (AVDD AVSS) ÷ 2. An external 0.1-F capacitor should be
connected between this terminal and AVSS.
D0 D7
2 9
O
Data outputs. D7 is the MSB.
DRVDD
1
I
Supply voltage for digital output drivers
DRVSS
10
I
Ground for digital output drivers
DVDD
14
I
Digital supply voltage
OE
13
I
Output enable. When high, the D0 D7 outputs go in high-impedance mode.
DVSS
11
I
Digital ground
PWDN_REF
24
I
Power down for internal reference voltages. A high on this terminal disables the internal reference circuit.
REFBI
21
I
Reference voltage bottom input. The voltage at this terminal defines the bottom reference voltage for the
ADC. It can be connected to REFBO or to an externally generated reference level. Sufficient filtering
should be applied to this input. The use of a 0.1-
F capacitor connected between REFBI and AVSS is
recommended. Additionaly, a 0.1-
F capacitor can be connected between REFTI and REFBI.
REFBO
22
O
Reference voltage bottom output. An internally generated reference is available at this terminal. It can be
connected to REFBI or left unconnected. A 1-
F capacitor between REFBO and AVSS provides sufficient
decoupling required for this output.
REFTI
20
I
Reference voltage top input. The voltage at this terminal defines the top reference voltage for the ADC.
It can be connected to REFTO or to an externally generated reference level. Sufficient filtering should be
applied to this input. The use of a 0.1-
F capacitor between REFTI and AVSS is recommended.
Additionaly, a 0.1-
F capacitor can be connected between REFTI and REFBI.
REFTO
19
O
Reference voltage top output. An internally generated reference is available at this terminal. It can be
connected to REFTI or left unconnected. A 1-
F capacitor between REFTO and AVSS provides sufficient
decoupling required for this output.
STBY
15
I
Standby input. A high level on this input enables power-down 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.
