Voltage-controlled attenuator

I 00 Moreover, the 1537A is de- signed for a high slew rate, resulting in low transient inter- modulation and a wide bandwidth, so that it can be used over the fre- quency range DC to 50 MHz. The very good perform- ance characteristics of the 1537A make it suitable for use in a wide range of audio applications, such as voltage-controlled filters, synthesizers, corn-. pressors, and others, as well as in, for instance, tone burst generators, robotics, servo-controlled machines, and many other general electronic applications. In general, voltage- controlled attenuators, which normally use log- antilog multiplier circuits, exhibit high non-linear dis- 2 1-1 (Pin Configuration) Voltage- controlled attenuator Although Aphex"s Type 1537A voltage-controlled attenuator has been on the market for some time, it appears that the device is not generally known. A pity, because it offers very low distortion, high stab- ility, low noise, and a wide dynamic range. Its attenuation can be con- troll...
