Several manufacturers offer op amp-based filter design tools [1-3]. Some tools choose off-the-shelf capacitor values, but others select non-standard ones. The option to alter passive component ...

A number of years ago, I posted an article and spreadsheet on EDN that enables the design of 2 nd and 3 rd order Sallen-Key low pass filters given the poles of their filter characteristics. The user ...

My previous column described the Sallen-Key circuit for a low-pass filter. At times, you will not find a low-pass filter with the specifications you need in an anti-alias circuit, so you might decide ...

The USBPGF-S1 is a USB-controlled single-channel programmable signal conditioning instrumentation amplifier and low pass filter. It provides users with the ability to mix and match filter ...

The LT6600-10 combines a high-speed differential amplifier and a 10-MHz low-pass filter. Gain is programmed with two resistors for a gain range of −12 to 12 dB. It also provides the necessary level ...
