PIN DESCRIPTIONS AND EQUIVALENT CIRCUITS (continued)

Pin No.

Symbol

Description

ANALOG I/O

5

SDATA

Digital data output. The output samples are clocked out of this pin on falling edges of the SCLK pin.

6

CS

Chip select. On the falling edge of CS, a conversion process begins.

POWER SUPPLY

Positive supply pin. This pin should be connected to a quiet +2.7V to +5.25V source and bypassed to

1

GND with a 1 µF capacitor and a 0.1 µF monolithic capacitor located within 1 cm of the power pin.

2

GND

The ground return for the supply and signals.

PAD

GND

For package suffix CISD(X) only, it is recommended that the center pad should be connected to ground.

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the

Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may

degrade when the device is not operated under the listed test conditions.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

(3)

All voltages are measured with respect to GND = 0V, unless otherwise specified.

(4)

10 mA. The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an

limited by the Analog Supply Voltage specification.

(5)

in a severe fault condition (e.g. when input or output pins are driven beyond the power supply voltages, or the power supply polarity is

reversed). Obviously, such conditions should always be avoided.

(6)

Human body model is 100 pF capacitor discharged through a 1.5 k

Ω resistor. Machine model is 220 pF discharged through zero ohms.
