Low-Noise, Low-Distortion,
1.35GHz Fully Differential Amplifiers
General Description
The MAX9626/MAX9627/MAX9628 are low-noise, low-
distortion, and high-bandwidth differential amplifier/ADC
drivers for use in applications from DC to 1.35GHz.
The exceptional low input-referred noise and low
distortion make these parts an excellent solution to
drive high-speed 12-bit to 16-bit pipeline ADCs. The
output common mode is set through the VOCM input
pin, thus eliminating the need for a coupling transformer
or AC-coupling capacitors. The ICs feature shutdown
mode for power savings and are offered in a 12-pin,
3mm x 3mm TQFN package for operation over a -40NC
to +125NC temperature range.
