Datasheet

MAX9626/MAX9627/MAX9628
Low-Noise, Low-Distortion,
1.35GHz Fully Differential Amplifiers
4
Note 1: All devices are 100% production tested at T
A
= +25°C. Temperature limits are guaranteed by design.
Note 2: Input voltage range is a function of VOCM. See the Input Voltage Range section for details.
Note 3: Limits are guaranteed by design based on bench characterization. Testing is functional using different limits.
