Overview
The DAC7731EB/1K is a 16-bit, single-channel Digital-to-Analog Converter (DAC) produced by Texas Instruments. It is designed to provide high precision and flexibility, making it suitable for various industrial and test equipment applications. The DAC7731EB/1K features a +10V internal reference and supports both unipolar and bipolar operation through pin strapping. It includes a high-speed output amplifier with a settling time of 5µs to ±0.003% Full-Scale Range (FSR) for a 20V full-scale change, and it consumes a typical power of 100mW. The device is available in a small SSOP-24 package and operates over a temperature range of –40°C to +85°C.
