• THAT2252 RMS Audio Level Detector, Qty 2

The THAT 2252 integrated-circuit rms level detector is designed to convert an AC input current into a DC output voltage. The output is proportional to the log of the true rms value of the input signal. Fabricated in a super low-noise process, the 2252 combines wide dynamic range with frequency response to beyond 20 kHz. The logarithmic output is especially convenient for audio applications requiring decibel-linear scaling. The integration time is adjustable via an external R/C pair. With some external circuitry, response to DC is also possible.
