TRUE RMS TO DC CONVERTER
Most current sensors produce outputs that are instantaneous representations
of the measured currents. For complex or ac waveshapes there may be a
requirement to convert the outputs to true rms values.
RMS converters available from Maxim are designed to accept complex
input waveforms containing ac and dc components. They can be operated from
either a single or dual supplies. The converters are designated MX536A/MX636.
Both devices draw less than 1 mA of quiescent supply current, making them ideal
for battery-powered applications. They exhibit >1MHz bandwidth and <.5% ac-
curacy. (www.maxim-ic.com)
CREATE -12Vdc FROM +12Vdc
Texas Instruments PT78NR112 creates a negative output voltage from +12Vdc
input. These easy-to-use, 3-terminal, Integrated Switching Regulators have
maximum output power of 5 watts and a negative output voltage that is laser
trimmed. They also have excellent line and load regulation. They can be used
with current sensors that reguire ±12Vdc power supplies. (www.ti.com)
DEFINITIONS
Response Time
Response time is defined as the
delay between the instant the
sensed current reaches 90% of
its final value and the instant
the sensor output signal reaches
90% of final value as illustrated
in Figure 7. For open loop
sensors response time and di/dt
ratings depend primarily upon
the slew rate of the amplifier.
di/dt accurately followed
The linear rate of change in current that the sensor can accurately measure.
Linearity
Output deviation from a straight line response to the current being measured.
