... Full-scale delay range is set by the combination of an external resistor and capacitor, and can range from 2 for a REV. A Information furnished by Analog Devices is believed to be accurate and reliable. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties which may result from its use ...

THEORY OF OPERATION The AD9501 is a digitally programmable delay device. Its function is to provide a precise incremental delay between input and output, proportional to an 8-bit digital word applied to its delay control port. Incremental delay resolution is ...

AD9501 Offset between the two levels is necessary for three reasons. First, offset allows the ramp to reset and settle without re- entering the voltage range of the DAC. Second, the DAC may overshoot as it switches to its most ...

Ramp charging current and DAC full-scale current are slaved together in the AD9501 to minimize delay drift over tempera- ture. To preserve the unit’s low drift performance, both R and C should have low temperature coefficients. Resistors EXT which are ...

AD9501 For most applications, OUTPUT can be tied to RESET. This causes the output pulse to be narrow (equal to the Reset Propagation Delay t ). Alternatively, an external pulse can be RD applied to RESET. To assure a valid ...

This delay matching is often difficult when using high speed, high-pin-count testers because lead length and circuit impedance can change when the tester setup is changed for different types of devices. The skew which might result from these changes can ...

AD9501 AD9501 #1 should be programmed so its delay is greater than the zero-set programmed delay of AD9501 #2. To accomplish this, continue to apply clock pulses and increment the digital data into AD9501 #1 until the output of the ...
