Achieving both high-speed response and stability! All the basic circuits required for a digital multimeter are integrated within the chip!
"HAZ01" is an IC for digital multimeters that employs a 0.25μm CMOS process. The digital calibration function eliminates offset and gain drift, achieving high stability. The effective value calculation unit is composed of a digital filter calculator and a digital filter, enabling fine control of calculations. As a result, by optimizing characteristics according to measurement conditions, both fast response and stability have been achieved. 【Features】 ■ High stability ■ Fast response ■ Multifunctional analog circuit ■ Simultaneous measurement of effective value/average value *For more details, please refer to the related link page or feel free to contact us.
