That 2252 RMS Level Detector Available In 8 Pin SIP

THAT Corporation's 2252 RMS Level Detector  ICs are now available in small quantities at affordable prices. Now you no longer have to buy an entire tube when you need just a few.

A critical function in modern electronics is accurately sensing the level of a signal. All of THAT Corporation's level detectors respond logarithmically (that is, by producing an output scaled in decibels -- dBs) to the RMS value of the input signal. RMS response produces natural-sounding response to transient information, which is important in the design of dynamics processors. Based on technology originally developed at dbx, THAT's level detectors are used by manufacturers of compressors, limiters, gates etc. to determine the level of audio signals.

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. The parts are housed in a space-efficient plastic 8-pin single-in-line (SIP) package, and require minimal support circuitry.

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.

Because the 2252 scales its output voltage logarithmically, it offers a particularly good match to THAT Corporation Voltage Controlled Amplifier (VCA) ICs.
