RC7151

The RC7151 is designed as one kind of monolithic building block used to convert DC voltage to digital pulses. The frequency of the output pulses is proportional to the DC input voltage. And this device consists of a voltage comparator, a monostable multivibrator and a precision switched current source. Also it is the same device as the uA4151 with a high performance operational amplifier on the same chip.

Features of the RC7151 are:(1)single supply (+8 VDC to +30VDC);(2)linearity to +/-0.05%;(3)programmable scale factor;(4)pulse output compatible with any logic form;(5)temperature stability typically +/- 100 ppm;(6)high noise rejection;(7)easily full-scale trim;(8)single-ended input, referenced to ground;(9)also provides frequency-to-voltage conversion.

The absolute maximum ratings of the RC7151 can be summarized as:(1)supply voltage: 32 V;(2)internal power dissipation: 670 mW;(3)input voltage (comparator): -0.2V to +Vcc;(4)input voltage (op amplifier): -0.2V to +Vcc;(5)logic out shorted-to-ground: continuous;(6)op amp out shorted-to-ground: continuous;(7)op amp output voltage range: +2V to +13V;(8)operating temperature range: 0 to +70;(9)storage temperature range: -65 to +150.
