LM131

The LM131 is designed as one kind of precision voltage-to-frequency converter that can be used in all standard voltage-to-frequency converter applications. Also this device is ideally suited for use in simple low-cost circuits for analog-to-digital conversion, precision frequencyto-voltage conversion, long-term integration, linear frequency modulation or demodulation, and many other functions.

Features of the LM131 are:(1)guaranteed linearity 0.01% max; (2)improved performance in existing voltage-to-frequency conversion applications; (3)split or single supply operation; (4)operates on single 5V supply; (5)pulse output compatible with all logic forms; (6)excellent temperature stability, g50 ppm/§C max; (7)low power dissipation, 15 mW typical at 5V; (8)wide dynamic range, 100 dB min at 10 kHz full scale frequency; (9)wide range of full scale frequency, 1 Hz to 100 kHz; (10)low cost.

The absolute maximum ratings of the LM131 can be summarized as:(1)supply voltage:40 V;(2)output short circuit to ground:continuous;(3)output short circuit to Vcc:continuous;(4)input voltage:-0.2V to +Vs;(5)operating ambient temperature range:-55 to +125;(6)ESD susceptibility metal can package (TO-5):2000 V.
