Hot-selling and scarce AD9100JD Ultrahigh Speed Monolithic Track-and-Hold CDIP20 spot stock

Product Descriptions

The AD9100 is a monolithic track-and-hold amplifier which sets a new standard for high speed and high dynamic range applications. It is fabricated in a mature high speed complementary bipolar process. In addition to innovative design topologies, a custom package is utilized to minimize parasitics and optimize dynamic performance.

Acquisition time (hold to track) is 13 ns to 0.1% accuracy, and 16 ns to 0.01%. The AD9100 boasts superlative hold-mode frequency domain performance; when sampling at 30 MSPS hold mode distortion is less than 83 dBfs for analog frequencies up to 12 MHz; and –74 dBfs at 20 MHz. The AD9100 can also drive capacitive loads up to 100 pF with little degradation in acquisition time; it is therefore well suited to drive 8- and 10-bit flash converters at clock speeds to 50 MSPS. With a spectral noise density of 3.3 nV/√Hz and feedthrough rejection of 83 dB at 20 MHz, the AD9100 is well suited to enhance the dynamic range of many 8- to 16-bit systems.

The AD9100 is “user friendly” and easy to apply: (1) it requires +5 V/–5.2 V power supplies; (2) the hold capacitor and switch power supply decoupling capacitors are built into the DIP package; (3) the encode clock is differential ECL to minimize clock jitter; (4) the input resistance is typically 800 kΩ; (5) the analog input is internally clamped to prevent damage from voltage transients.

The AD9100 is available in a 20-lead side-brazed “skinny DIP” package. Commercial, industrial, and military temperature grade parts are available. Consult the factory for information about the availability of 883-qualified devices.
