Texas Instruments LM231 Precision Voltage-to-Frequency Converter LM231N

The LM231 Precision Voltage-to-Frequency Converter from Texas Instruments is designed for applications requiring accurate voltage-to-frequency conversion. It features a maximum linearity of 0.01% and operates on a single 5-V supply, consuming approximately 15 mW of power. The device supports a wide dynamic range of at least 100 dB at a full-scale frequency of 10 kHz and can handle full-scale frequencies ranging from 1 Hz to 100 kHz. The LM231 offers excellent temperature stability with a drift of ±50 ppm/°C, making it suitable for precision applications. It is compatible with all logic forms and can drive multiple TTL loads or high-voltage outputs up to 40 V. The device is packaged in an 8-pin PDIP format and is rated for operation within a temperature range of -25 to 85 °C. This product is ideal for use in low-cost circuits for analog-to-digital conversion, remote sensor monitoring, and tachometers.
