MX636

19-0824; Rev 2; 3/96 True RMS-to-DC Converters General Description The MX536A and MX636 are true RMS-to-DC converters. They feature low power and are designed to accept low-level input signals from 0 to 7VRMS for the MX536A and 0 to 200mVRMS for the MX636. Both devices accept complex input waveforms containing AC and DC components. They can be operated from either a single supply or dual supplies. Both devices draw less than 1mA of quiescent supply current, making them ideal for battery-powered applications. Input and output offset, positive and negative waveform symmetry (DC reversal), and full-scale accuracy are laser trimmed, so that no external trims are required to achieve full rated accuracy. ____________________________Features o True RMS-to-DC Conversion o Computes RMS of AC and DC Signals o Wide Response: 2MHz Bandwidth for VRMS > 1V (MX536A) 1MHz Bandwidth for VRMS > 100mV (MX636) o Auxiliary dB Output: 60dB Range (MX536A) 50dB Range (MX636) o Single- or Dual-Supply Operation o Low Power: 1.2mA typ (MX536A) 800µA typ (MX636) MX536A/MX636 Ordering Information PART MX536AJC/D MX536AJCWE MX536AJD MX536AJH MX536AJN MX536AJQ* MX536AKCWE MX536AKD MX536AKH MX536AKN MX536AKQ* MX536ASD TEMP.
