The ±0.01% linearity spec means the deviation from an ideal straight-line transfer function is within 100 ppm of full scale across the operating range, so a 0–10 V input mapping to 0–100 kHz output stays within 10 Hz of the ideal frequency at any point. The full-scale drift is ±50 ppm/°C, which sets the thermal stability floor. A 10 °C ambient shift moves the output by 0.05% of full scale — for a 100 kHz full-scale output that is 50 Hz of drift. If the system sees a 50 °C swing, budget 250 Hz of zero-and-gain shift before any software compensation. The supplier device package is 8-PDIP; the 0.300-inch width is the narrow DIP variant, not the 0.600-inch wide-body, so verify the board layout matches the narrower row spacing. Supplied in tube packaging — 50 parts per tube typical for 8-pin DIP. No tape-and-reel option for this through-hole package.","metaTitle":"Texas Instruments LM231AN/NOPB Voltage-to-Frequency","metaDescription":"Active-production voltage-to-frequency converter from TI. ±0.01% linearity, 100 kHz max, 8-DIP package.
