LM231 LM231N Technical Datasheet

Description over the full operating temperature range, at power supplies as low as 4.0V. The precision timer circuit has low bias The LM231/LM331 family of voltage-to-frequency converters currents without degrading the quick response necessary for are ideally suited for use in simple low-cost circuits for 100 kHz voltage-to-frequency conversion. And the output analog-to-digital conversion, precision frequency-to-voltage are capable of driving 3 TTL loads, or a high voltage output conversion, long-term integration, linear frequency modula- up to 40V, yet is short-circuit-proof against VCC. tion or demodulation, and many other functions. The output when used as a voltage-to-frequency converter is a pulse train at a frequency precisely proportional to the applied Features input voltage. Thus, it provides all the inherent advantages of n Guaranteed linearity 0.01% max the voltage-to-frequency conversion techniques, and is easy n Improved performance in existing voltage-to-frequency to apply in all standard voltag
