Pin Functions

REFCOMP (Pin 34): Internal Reference Compensation Pin.

For low noise and reference stability, tie a 0.1µF capacitor

to GND. Tying REFCOMP to GND causes the part to power

up with the internal reference disabled, allowing the use

of an external reference at start-up.

AVP (Pin 36): Analog Supply Voltage Input. 4.5V ≤ AVP ≤

5.5V. Bypass to GND with a 1µF capacitor.

OVRTMP (Pin 38): Thermal Protection Interrupt Pin. This

open-drain N-channel output pulls low when chip tem-

perature exceeds 160°C. This pin is released on the next

CS/LD rising edge. A pull-up resistor is required.

MSP0 (Pin 39): MSPAN Bit 0. Tie this pin to AVP or GND

to select the power-on span and power-on-reset code for

all 16 channels (see Table 4).

MSP1 (Pin 40): MSPAN Bit 1. Tie this pin to AVP or GND

to select the power-on span and power-on-reset code for

all 16 channels (see Table 4).

Exposed Pad (Pin 41): Analog Negative Supply (V–). Must

be soldered to PCB.
