One of the more common building blocks of a voltage controlled amplifier (VCA) is a differential pair amplifier. For a VCA configuration, the (top) two bases receive a control voltage for gain control ...

Introduced as the industry's first single-chip differential amplifier capable of driving 14-bit a/d converters at 70 MHz, the AD8351 supports 10-bit distortion performance at speeds up to 240 MHz.

The input stage of an amplifier performs the critical duty of subtracting the feedback signal from the input, to generate the error signal that drives the output. It ...

A pair of differential amplifiers, the AD8139 and AD8137, can drive 12-, 16- and 18-bit high-speed a/d converters in applications ranging from battery powered data acquisition systems to ...
