PMIC stands for Power Management Integrated Circuit, and RMS to DC Converters refer to power converters that converts RMS (root mean square) electrical signals into DC (direct current). The AD736AR-REEL is one such device which belong in this category.

The AD736AR-REEL is a monolithic, 13-pin converter chip whose RMS-to-DC conversion is optimized for high-accuracy and wide dynamic range. This device has a slew rate of 500V/µs and an adjustable voltage range from 0.25 to 3.7V/V. It is designed for applications such as AC line measurements, programmable-gain amplifiers, and low-power circuits.

The input of the converter is a differential AC or DC signal, and its output is a high-precision DC signal whose amplitude is proportional to the input signal level. The AD736AR-REEL has a low offset voltage of ±120 mV and a low input current of 20 nA, making it ideal for applications where accuracy and precision is of paramount importance. The device also features high input impedances (950Kohm) and low output noise levels (0.1µV result in dynamic range of up to 120dB).

The main features of AD736AR-REEL include an adjustable voltage range from 0.25 to 3.7V/V, high input impedance of 950Kohm, low input current of 20 nA, low offset voltage of ±120 mV, and low output noise (0.1µV). It is designed for applications with maximum accuracy and precision such as AC line measurements, programmable-gain amplifiers and low-power circuits, and its slew rate of 500V/µs gives it an advantage over competing devices in the same category.

The working principle of the AD736AR-REEL is simple. The input signal is first fed into an internal voltage amplifier that amplifies the signal by a factor of 2.5. This amplified signal is then converted by the converter’s low distortion analog-to-digital converter, and finally, the digital signal is compared to a reference signal. The output is an accurate and precise DC signal whose amplitude is proportional to the input signal level.

The AD736AR-REEL is a versatile and powerful RMS-to-DC converter which is suitable for a wide range of applications. Its wide dynamic range and low noise levels make it ideal for applications that require accuracy and precision, such as AC line measurements, programmable-gain amplifiers, and low-power circuits. Its slew rate of 500V/µs gives it an advantage over competing devices in the same category.
