Power up the host system, with the RESET pin pulled to ground via a ≤4.7kꢀ resistor.
Drive the RESET pin LOW.
Ensure power to the unit is on.
Drive the RESET pin HIGH to release the unit to become operational.
Read byte A2.6E several times. There will be a NACK until the processor is booted, followed by a 01 (DATA READY BAR)
until the A2D data is ready, followed by 00 (assuming TXDIS and TXFAIL are inactive).

Ordering Information
Table 9 - Ordering Information
Table 10 - Device Handling/ESD Protection
The devices are static sensitive and may easily be damaged if care is not taken during handling. The following handling practices are
recommended.
1
2
3
4
5
6
Devices should be handled on benches with conductive and grounding surfaces.
All personnel, test equipment and tools shall be grounded.
Do not handle the devices by their leads.
Store devices in protective foam or carriers.
Avoid the use of non-conductive plastics, rubber, or silk in the area where the devices are handled
All modules shall be packaged in materials that are anti-static to protect against adverse electrical environments.
Avoid applications of any voltage higher than maximum rated voltages to this part. For proper operation, any VIN or VOUT should be
constrained to the range GND ≤ (VIN or VOUT) ≤ VCC. Unused inputs must always be tied to an appropriate logic voltage (e.g.
either GND or VCC). Unused outputs must be left open.

Warnings
Handling Precautions: This device is susceptible to damage as a result of electrostatic discharge (ESD). A static free environment is highly
recommended. Follow guidelines according to proper ESD procedures.
Laser Safety: Radiation emitted by laser devices can be dangerous to human eyes. Avoid eye exposure to direct or indirect radiation.
