OPERA TING INSTRUCTIONS
POW ER SUPPLY A ND
GROUNDING CONSIDERA TIONS
Clearly, the management of IR drops, power supply
noise, thermal stability and environmental noise
become critical issues when designing an 18-bit system.
To optimize the absolute accuracy of a high resolution
system, the following rules of thumb have to be followed:
1. Selection of low noise operation power supplies.
2. Proper decoupling of the supplies at the DA C using
10F ceramic disk capacitor.
3. Usage of the “ holy point” grounding technique.
4. “ K elvin-sensed-output” connection of the DA C
the load.
Consult factory for application information.

NOTES: 1. Digital input must not exceed supply voltage or go below 0.5V . 2. V IL 0.4, V HL 3.2.
3. Time that data must be stable before latch control goes to 0. 4. Time that data must be stable after latch control goes to 0.
5. Intearal Linearity, for this product, is measured as the arithmetic mean value of the magnitudes of the greatest positive deviation and the
greatest negative deviation from the theoretical value for any given input combination.
