Op. Mode Selection Input:

100% VCC = x2 interpolated

75% VCC = ABZ analog, UVW digital

50% VCC (or pin open) = all analog

25% VCC = x4 interpolated

0% VCC = x1 comparated (native res.)

20 V

Push-Pull Output V / Analog V

21 TIP

Positive Test Current Input 3

22 U

Push-Pull Output U / Analog U

23 T1

Index Gating Selection Input:

lo = 0.5 T (B-gated),

hi = 1 T (ungated/T-gated),

open = 0.25 T (AB-gated)

24 GND Ground

25..32 n.c.

Backside Paddle 4

IC top marking: <P-CODE> = product code, <A-CODE> = assembly code (subject to changes);

1 Capacitive pin loads must be avoided when using the analog output signals.

2 Pin numbers marked n.c. are not connected.

3 The test pins TIP and TIN may remain unconnected.

4 Connecting the backside paddle is recommended by a single link to GND. A current flow across the paddle is not permissible.
