The LM331N is an Analog to Digital Converter (ADC) with 8-pin DIP package manufactured by HGSEMI. It is RoHS compliant and features a ±2% capacitor reference input, a measure rate of up to 300 kHz, and a 12-bit successful conversion rate. It has an analog signal voltage input range of -10V to +10V, and a binary output voltage range of 0 ~ 5V. It has an accuracy of ±2% over a temperature range of 0°C to 70°C with a power supply of ±5V DC. For a single ended input, the LM331N features a maximum throughput of 300 kHz, a digital feed-forward cancellation, and programmable thresholds. Additionally, the device features a power-on reset function and a programmable OFM logic. This ADC offers high speed conversion, high accuracy, and wide dynamic range conversion and is ideal for applications such as data logging, remote sensing, instrumentation, and industrial process control.
