IR9331

The IR9331 is designed as voltage to frequency converter which would ideally suited for use in simple low-cost circuits for AD conversion, precision F/V conversion, longterm intergration, linear frequency modulation or demodulation, and many other functions.

IR9331 has six features. (1)Guaranteed linearity 0.01%FS max. (2)Excellent temperature stability +/-30ppm/°C typ. (3)Wide dynamic range 100dB at 10kHz FS min. (4)Wide range of supply voltage 4 to 40V. (5)Wide range of FS frequency 1 to 100kHz. (6)8-pin dual in line package. Those are all the main features.

Some absolute maximum ratings of IR9331 have been concluded into several points as follow. (1)Its supply voltage would be 40V. (2)Its input voltage would be from -0.2V to Vcc. (3)Its output short circut time would be indinity. (4)Its power dissipation would be 500mW. (5)Its power dissipation derating ratio would be 4.5mW/°C. (6)Its operating temperature range would be from -10°C to +70°C. (8)Its storage temperature range would be from -55°C to +150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of IR9331 are concluded as follow. (1)Its VFC non linearity error would be typ +/-0.003%FS and max +/-0.01%FS. (2)Its scale factor gain would be min 0.9kHz/V and typ 1.0kHz/V and max 1.1kHz/V. (3)Its gain temperature coefficient would be typ +/-30ppm/°C. (4)Its gain power supply stability would be tyo 0.01%/V and max 0.15%/V. (5)Its full scale frequency would be min 10kHz. (6)Its over range frequency would be min 10%. (7)Its offset voltage would be typ +/-3mV and max +/-10mV. (8)Its bias current would be typ -80mA and max -300mA. (9)Its offset current would be typ +/-8nA and max +/-100nA. (10)Its in-phase input range would be min -0.2V and max Vcc-2.0V. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
