    Differential amplifiers/ADC drivers boost performance by eliminating parasitics


      Maxim has announced a family of differential amplifiers, the MAX9626-9628, which integrate gain resistors to eliminate parasitics and enable higher bandwidths for high-speed pipeline ADCs.


      The 1.35GHz MAX9626–MAX9628 are suitable for driving 12- to 16-bit pipeline ADCs in communication, medical imaging, automatic test equipment, and high-performance instrumentation applications.


      The output common mode of the MAX9626–MAX9628 is set through one of the input pins (VOCM), thus eliminating the need for a coupling transformer or AC-coupling capacitors. This technology saves board space and improves performance by avoiding the uncertainties found in external components. In addition, the wide output common-mode range and ability to accept negative input signals with single-supply operation allow the parts to interface with the majority of ADCs on the market. This increases design flexibility and reduces time to market.

      The MAX9626–MAX9628 are available in a 3mm x 3mm, 12-pin TQFN package and are  specified over the -40°C to +85°C extended temperature range. Pricing starts at $2.90 (1000-up, FOB USA). Evaluation kits are available upon request.
