Item Details
AD835 Analog Multiplier Module
Phase Detection Measurement 250 MHz Four quadrant
Description:
This is the third version of the AD835 module, based on the original module design more reasonable and concise, smaller size, the use of more simple. PCB layout is more reasonable and beautiful, in strict accordance with the high-frequency alignment design, with a 2x2mm shield cover, isolated a number of large signal interference.
1, AD835 is the first single-chip 250MHz four-image voltage output multiplier.
2, AD835 for a variety of signal processing applications, with very few external devices.
3, High input impedance (100 kΩ || 2 pF) makes the signal source load negligible.
4, High output current capability to support driving low impedance load.
5, Through the careful optimization of the device and the use of special low noise bandgap reference voltage source, can achieve excellent low noise level.
6, Easy to use, cost-effective, suitable for the use of mixed or board-level applications.
Power Supply Range: ±5V
Module Size: 41mm x 39mm
Module Chip:
AD835 is a complete four-quadrant voltage output analog multiplier, Using advanced dielectric isolation complementary bipolar process manufacturing. It produces a linear product of the X and Y voltage inputs, 3dB output bandwidth of 250MHz (small signal rise time is 1ns). The full scale (1V to +1V) rises to a descending time of 2.5ns (using a 150Ω standard RL), 0.1% setup time is typically 20ns.
Its differential multiplication input (X, Y) and the summation input (Z) are in a high-impedance state. The low impedance output voltage (W) can be up to ±2.5V and can drive loads as low as 25Ω. Normal operation with ±5V power supply.
The AD835 not only has excellent speed performance, but also easy to use and feature-rich. For example, in addition to allowing the signal to be added at the output, the Z input can also amplify the operating voltage of the AD835 by up to about 10 times. Thus, the product noise of the multiplier is very low (50 nV / √Hz), much better than the earlier product.
The AD835 uses 8-lead PDIP package (N) and 8-lead SOIC package (R), it is rated temperature range of 40℃ ~ 85℃.
