AAT2860 Analogic Corporation, AAT2860 Datasheet - Page 4

• Manufacturer Part Number: AAT2860
• Manufacturer: Analogic Corporation

Electrical Characteristics
V
Typical values are T
1. The AAT2860 is guaranteed to meet performance specifications over the -40°C to +85°C operating temperature range and is assured by design, characterization, and correla-
2. Current matching is defined as the deviation of any sink/channel current from the average of all active channels.
