This Product Selection Guide contains information to help select products in the RMS to DC Converters category on DigiKey.com
Products in the RMS-to-DC converter family are used to perform a mathematical function of measuring a time-varying waveform and return a value proportional to the equivalent steady state (DC) value that would result in producing the same power dissipation if applied to a resistive load. Often used for measurements in AC power-related applications, they are differentiated among themselves and from other techniques used for similar ends by the degree of accuracy in the result given when the input is a non-sinusoidal waveform.
SelectionCharacteristics
Current - Supply: This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
