Description

6, 33

AVDD1

Power Supply for Modulator, 2.5 V. These pins should be decoupled to AGND1 with 100 nF and

10 μF capacitors on each pin.

4, 14, 15, 27

AVDD2

Power Supply, 5 V. These pins should be decoupled to AGND2 with 100 nF capacitors on each of

Pin 4, Pin 14, and Pin 15. Pin 27 should be connected to Pin 14 via an 8.2 nH inductor.

24

AVDD3

Power Supply for Differential Amplifier, 3.3 V to 5 V. This pin should be decoupled to AGND3

with a 100 nF capacitor.

12

AVDD4

Power Supply for Reference Buffer, 3.3 V to 5 V. This pin should be decoupled to AGND4

with a 10 nF capacitor in series with a 10

Ω resistor.

7, 34

AGND1

Power Supply Ground for Analog Circuitry Powered by AVDD1.

5, 13, 16, 18, 28

AGND2

Power Supply Ground for Analog Circuitry Powered by AVDD2.

23, 29, 31, 32

AGND3

Power Supply Ground for Analog Circuitry Powered by AVDD3.

11

AGND4

Power Supply Ground for Analog Circuitry Powered by AVDD4.

9

REFGND

Reference Ground. Ground connection for the reference voltage.

41

DVDD

Power Supply for Digital Circuitry and FIR Filter, 2.5 V. This pin should be decoupled to DGND

with a 100 nF capacitor.

44, 63

VDRIVE

Logic Power Supply Input, 1.8 V to 2.5 V. The voltage supplied at these pins determines

the operating voltage of the logic interface. These pins must be connected together and

tied to the same supply. Each pin should also be decoupled to DGND with a 100 nF capacitor.

1, 35, 42, 43, 53, 57, 59,

62, 64

DGND

Ground Reference for Digital Circuitry.

19

VINA+

Positive Input to Differential Amplifier.

20

VINA−

Negative Input to Differential Amplifier.

21

VOUTA−

Negative Output from Differential Amplifier.

22

VOUTA+

Positive Output from Differential Amplifier.

25

VIN+

Positive Input to the Modulator.

26

VIN−

Negative Input to the Modulator.

10

VREF+

Reference Input. The input range of this pin is determined by the reference buffer

supply voltage (AVDD4). See the Reference Voltage Filtering section for more details.

8

DECAPA

Decoupling Pin. A 100 nF capacitor must be inserted between this pin and AGND1.

30

DECAPB

Decoupling Pin. A 33 pF capacitor must be inserted between this pin and AGND3.
