4 Pin Configuration and Functions

Figure 4-1 DRL Package,
6-Pin SOT5X3
(Top View)
Table 4-1 Pin Functions
PIN TYPE(1) DESCRIPTION
NAME NO.
EN 3 I Device enable pin. EN = logic low = normal operation (default)(2); EN = logic high = low-power mode.
GND 5 I Amplifier ground
IDC_EN 6 I Ambient light cancellation loop enable. IDC_EN = logic low = enable dc cancellation (default)(2); IDC_EN = logic high = disable dc cancellation.
IN 1 I Transimpedance amplifier input
OUT 4 O Amplifier output
VDD 2 I Positive power supply
(1) I = input, O = output
(2) TI recommends driving a digital pin with a low-impedance source rather than leaving the pin floating because fast-moving transients can couple into the pin and inadvertently change the logic level.
