The CLC451 is a low cost, high speed (85MHz) buffer that features user-programmable gains of +2, +1, and -1V/V. It has a new output stage that delivers high output drive current (100mA), but consumes minimal quiescent supply current (1.5mA) from a single 5V supply. Its current feedback architecture, fabricated in an advanced complementary bipolar process, maintains consistent performance over a programmable range of gains and wide signal levels, and has a linear-phase response up to one half of the -3dB frequency. The CLC451's internal feedback network provides an excellent gain accuracy of 0.3%
