AD636KD Description

Short technical summary and product information.

The AD636KD from Analog Devices is a low-power, monolithic integrated circuit designed for true RMS-to-DC conversion of low-level signals. It offers high accuracy with a maximum error of 1.0% for the J-version and 0.5% for the K-version, specified for a signal range of 0 mV to 200 mV rms. The device supports crest factors up to 6 with less than 0.5% additional error, making it suitable for complex input waveforms.

 

With a bandwidth of 1 MHz at -3 dB for Vrms > 100 mV, the AD636KD is ideal for various measurement applications. It operates from a wide range of dual power supplies (±2.5 V to ±16.5 V) or single supplies (+5 V to +24 V), consuming a low quiescent current of typically 800 μA, which is beneficial for battery-powered instruments. The input and output terminals are protected, and the input signal can exceed the power supply without damage.

 

The AD636KD is housed in a 14-pin ceramic DIP (CDIP-14) package and is designed for through-hole mounting. It includes an auxiliary dB output derived from an internal circuit point, offering a 50 dB dynamic range. The device is factory-trimmed for input/output offset, waveform symmetry, and full-scale accuracy, eliminating the need for external trims to achieve full-rated accuracy.
