MAX9945 Maxim, MAX9945 Datasheet - Page 3

• Manufacturer Part Number: MAX9945
• Description: The MAX9945 operational amplifier features an excellent combination of low operating power and low input voltage noise
• Manufacturer: Maxim

ELECTRICAL CHARACTERISTICS (continued)
(V
unless otherwise noted.) (Note 2)
Note 2: All devices are 100% production tested at T
Note 3: Guaranteed by design. IN+ and IN- are internally connected to the gates of CMOS transistors. CMOS GATE leakage is so
Note 4: Specified over all temperatures and process variation by circuit simulation.
