AD9630

The AD9630 is a monolithic buffer amplifier that utilizes innovative (patent pending) closed-loop design techniques to achieve exceptional gain accuracy, wide bandwith, and low distortion. Slew rate limiting has been overcome as indicated by the 1200 V/µs 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 in one part outstanding dc and dynamic performance.

The large signal bandwith, low distortion over frequency, and drive capabilities of the AD9630 makes the buffer an ideal flash ADC driver. The AD9630 provides better signal fidelity than many of the flash ADCs than it has been designed to drive.

Other applications which require increased current drive at unity voltage gain such as cable driving benefit from the AD9630's performance.

The AD9630 is available in Plastic DIP (N), Ceramic DIP (Q), and SOIC (R). Consult with the factory concerning availability of MIL-STD-883 parts. Die are dc tested at -25°C.
