Mnemonic

Description

K1, K2

V+

V+ Amplifier Supply Pins.

K3 to K14

AGND

Analog GND Pins.

L1, L2

NC

No Connect. Do not connect to these pins.

L3 to L13

AGND

Analog GND Pins.

L14

DAC_GND

Reference GND Supply for All DACs.

M1 to M12

AGND

Analog GND Pins.

M13, M14

AVCC

Analog Supply Pins.

N1, N2

PGND

Output Amplifier Ground Reference Pins.

N3

CATHODE

Cathode of Internal Diode for Diode Temperature Measurement.

N4

ANODE

Anode of Internal Diode for Diode Temperature Measurement.

N5 to N14

AGND

Analog GND Pins.

P1

NC

No Connect. Do not connect to these pins.

P2

REF_IN

Reference Voltage for Channel 0 to Channel 31.

P3

DAC_GND

Reference GND Supply for All DACs.

P4

RESET

Active Low Input. This pin can also be used to reset the complete device to its power-on reset conditions.

Zero code is loaded to the DACs.

P5

DVCC

Digital Supply Pins.

P6

DGND

Digital GND Pins.

P7

TEST

For normal operation, tie this pin low.

P8

DIN

Serial Data Input. Data must be valid upon the falling edge of SCLK.

P9

SCLK

Serial Clock Input. Data is clocked into the shift register upon the falling edge of SCLK. The pin operates

at clock speeds of up to 30 MHz. Internal pull-up device on logic input. Therefore, it can be left floating

and defaults to a logic high condition.

P10

SYNC

Active Low Input. This is the frame synchronization signal for the serial interface. While SYNC is low, data

is transferred in upon the falling edge of SCLK.

P11 to P13

AGND

Analog GND Pins.

P14

NC

No Connect. Do not connect to these pins.
