Bandpass-filtered -40-dB attenuator: less than 0.1-dB error reference design

This TI Verified Design is a -40dB band-pass filtered inverting attenuator. The circuit creates a filtered: inverted: and attenuated output from a single-ended input signal that can be used for test and measurement: or other waveform generation applications. A single low-noise OPA1611 op amp is used to invert: attenuate: and filter the input signal. The low-noise and low-distortion performance of the OPA1611 allows for a very accurate and clean output signals.See more TI Precision Designs
