OBS emitterfollowers. the BUF-{)3utilizes a quasi-quad FETinput structure to optimize both speed and D.C. input characteristics. On-chipzener-zap trimming is used to achieve low offset voltage while careful biasing throughout results in excell_entgain linearity over the full Input voltage range. Applications for which the BUF-{)3is well-suited include high-speed line drivers. isolation amplifiers for driving reactive loads. and high-speed sample-hold circuits. PIN CONNECTIONS N.C. .
