AD9100中文资料Ultrahigh Speed Monolithic Track-and-Hold数据手册ADI规格书

描述 Description

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 -74dBfs 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/(root)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:
• It requires +5 V/-5.2 V power supplies

• The hold capacitor and switch power supply decoupling capacitors are built into the DIP package

• The encode clock is differential ECL to minimize clock jitter

• The input resistance is typically 800 kOhm

• The analog input is internally clamped to prevent damage from voltage transients.

The AD9100 is available in a 20-lead size-brazed \"skinny DIP\" package and a 28-lead LCC package. Commercial, industrial, and military temperature grade parts are available. Consult the factory for information about the availability of 883-qualified devices.
