• Manufacturer Part Number: ICL7104-14CPL
• Description: 14 BIT A/D CONVERTER
• Manufacturer: Intersil

Specifications of ICL7104-14CPL

• Rohs Status: RoHS non-compliant
• Other names: NT5018

System Electrical Specifications: ICL8052/ICL7104
NOTES:
11. Tested with low dielectric absorption integrating capacitor.
12. The input bias currents are junction leakage currents which approximately double for every 10
13. The temperature range can be extended to 70
14. System Electrical Specifications are not tested; for reference only.

the junction temperature rises above the ambient temperature as a result of internal power dissipation, P
R

. Due to limited production test time, the input bias currents are measured with junctions at ambient temperature. In normal operation
is the thermal resistance from junction to ambient. A heat sink can be used to reduce temperature rise.
