FUNCTION
Hold Logic Input. Connect HOLD to DV DD to hold the current ADC value on the LED. Connect
HOLD to GND to update the LED at a rate of 2.5Hz and disable the hold function. Placing the
device into hold mode initiates an offset mismatch calibration. Assert HOLD high for a minimum of
2s to ensure the completion of offset mismatch calibration (see Table 1).
Display Decimal-Point Logic-Input 2. Controls the decimal point of the LED. See the Decimal-Point
Control section.
Display Decimal-Point Logic-Input 1. Controls the decimal point of the LED. See the Decimal-Point
Control section.

Active-High LED Enable. The MAX1365/MAX1367 display driver turns off when LED_EN is low.
The MAX1365/MAX1367 LED-display driver turns on when LED_EN is high.
-2.5V Charge-Pump Voltage Output. Connect a 0.1μF capacitor to GND.
Decimal-Point Enable Input. Controls the decimal point of the LED. See the Decimal-Point Control
section. Connect DPON to DV DD to enable the decimal point.
ADC Negative Reference Voltage Input. For internal reference operation, connect REF- to GND.
For external reference operation, bypass REF- to GND with a 0.1μF capacitor and
set V REF- from -2.2V to +2.2V (V REF+ > V REF- ).
ADC Positive Reference Voltage Input. For internal reference operation, connect a 4.7μF capacitor
from REF+ to GND. For external reference operation, bypass REF+ to GND with a 0.1μF capacitor
and set V REF+ from -2.2V to +2.2V (V REF+ > V REF- ).
