The AD9630 is a monolithic buffer amplifier that utilizes a patented, innovative, closed-loop design technique to achieve exceptional gain accuracy, wide bandwidth, and low distortion. Slew rate limiting has been overcome as indicated by the 1200 V/s slew rate; this improvement allows the user greater flexibility in wideband and pulse applications. The second harmonic distortion terms for an analog input tone of 4.3 MHz and 20 MHz are 80 dBc and 66 dBc, respectively. Clearly, the AD9630 establishes a new standard by combining outstanding dc and dynamic performance in one part.
