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 the -40°C to +125°C temperature range.
