AD737[Low Cost, Low Power, True RMS-to-DC Converter]

other part :AD737ANZ   AD737ARZ   AD737JNZ   AD737JRZ   AD737JRZ-R7   AD737JRZ-RL   AD737JRZ-5  

GENERAL DESCRIPTION
The AD737 is a low power, precision, monolithic, true rms-to dc converter. It is laser trimmed to provide a maximum error of ±0.2 mV ± 0.3% of reading with sine wave inputs. Furthermore, it maintains high accuracy while measuring a wide range of input waveforms, including variable duty cycle pulses and triac (phase) controlled sine waves. The low cost and small physical size of this converter make it suitable for upgrading the performance of non-rms precision rectifiers in many applications. Compared to these circuits, the AD737 offers higher accuracy at equal or lower cost.

AD7376[±15 V Operation Digital Potentiometer]

other part :AD7376AN10   AD7376AR10   AD7376ARU10   AD7376AN50   AD7376AR50   AD7376ARU50   AD7376AN100  

GENERAL DESCRIPTION
The AD7376 provides a single channel, 128-position digitally controlled variable resistor (VR) device. This device performs the same electronic adjustment function as a potentiometer or variable resistor. These products were optimized for instrument and test equipment applications where a combination of high voltage with a choice between bandwidth or power dissipation are available as a result of the wide selection of end-to-end terminal resistance values. The AD7376 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI-compatible serial-input register. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. The variable resistor offers a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper. The fixed A to B terminal resistance of 10 kΩ, 50 kΩ, 100 kΩ or 1 MΩ has a nominal temperature coefficient of –300 ppm/°C.
