Lowest distortion from dc to 100 MHz
The ADA4937 and ADA4938 set new differential amplifier performance standards from dc to 100 MHz. Best-in-class low noise, low distortion, high SFDR, and wide bandwith combine to make both parts ideal for driving high speed, 12- to 16-bit ADCs. For example, now you can have true 14-bit performance at 70 MHz, and true 16-bit performance at 40 MHz. Additional features include adjustable gain and output common-mode voltage, a wide supply range, and small LFCSP packaging. more ...

Wideband A/D Converter Front-End Design Considerations II: Amplifier or Transformer Drive for the ADC?
Design of the input configuration, or "front end", ahead of a high-performance analog-to-digital converter (ADC) is critical to achieving desired system performance. more ...
Analog Dialogue: High Speed Op Amp Drives a 16-bit, 1 MSPS Differential-Input A/D
Modern high resolution analog-to-digital converters (ADCs) usually require input buffer amplifiers (ADC drivers), because they often present a dc load of several hundred ohms or more–and a high frequency dynamic load–to the source that is driving them. If the source is a transducer or a typical low frequency preamplifier, significant errors may occur. more ...
