AD835ARZ 高速模拟乘法器
The AD835 is a complete four-quadrant voltage output analog multiplier fabricated on an advanced dielectrically isolated complementary bipolar process. It generates the linear product of its X and Y voltage inputs, with a -3 dB output bandwidth of 250 MHz (a small signal rise time of 1 ns). Full-scale (-1 V to +1 V) rise/fall times are 2.5 ns (with the standard RL of 150 Ohm) and the settling time to 0.1% under the same conditions is typically 20 ns.
Its differential multiplication inputs (X, Y) and its summing input (Z) are at high impedance. The low impedance output voltage (W) can provide up to ±2.5 V and drive loads as low as 25 Ohm. Normal operation is from ±5 V supplies.
Though providing state-of-the-art speed, the AD835 is simple to use and versatile. For example, as well as permitting the addition of a signal at the output, the Z input provides the means to operate the AD835 with voltage gains up to about x10. In this capacity, the very low product noise of this multiplier (50 nV(root)Hz) makes it much more useful than earlier products.
The AD835 is available in an 8-pin plastic mini-DIP package (N) and an 8-pin SOIC (R) and is specified to operate over the -40°C to +85°C industrial temperature range.
