Mnemonic

Description

14

LATCHB

Latch B. A logic low on this pin allows the gain to change on Channel B in parallel gain control

interface mode. A logic high on this pin prevents gain changes.

15

VINB−

Channel B Negative Analog Input.

16

VINB+

Channel B Positive Analog Input.

17

PWUPB

Channel B Power-Up. A logic high on this pin powers up Channel B, and a logic low on this pin

disables it.

18

VCMB

Channel B Common-Mode Output.

21

VOUTB−

Channel B Negative Analog Output.

22

VOUTB+

Channel B Positive Analog Output.

24, 27

VPOS

Positive Power Supply.

29

VOUTA+

Channel A Negative Analog Output.

30

VOUTA−

Channel A Positive Output.

33

VCMA

Channel A Common-Mode Output.

34

PWUPA

Channel A Power-Up. A logic high on this pin powers up Channel A, and a logic low on this pin

disables it.

35

VINA+

Channel A Positive Analog Input.

36

VINA−

Channel A Negative Analog Input.

37

LATCHA

Latch A. A logic low on this pin allows the gain to change on Channel A in the parallel gain

control interface mode. A logic high on this pin prevents gain changes.

38

UPDN_DAT_A/A0

Data Pin for the Channel A Up/Down Function (UPDN_DAT_A).

Bit 0 for Channel A in Parallel Gain Control Interface Mode (A0).

39

UPDN_CLK_A/A1

Clock Interface for the Channel A Up/Down Function (UPD_CLK_A).

Bit 1 for Channel A in Parallel Gain Control Interface Mode (A1).

40

FA_A/A2

Fast Attack for Channel A (FA_A). In serial mode, a logic high on this pin attenuates Channel A

according to an FA SPI word.

Bit 2 for Channel A in Parallel Gain Control Interface (A2).

EP

GND

Exposed Pad Ground. The exposed pad must be connected to a low impedance ground plane.

This is the ground (0 V) reference for all the voltages in Table 1.
