Overview
The DAC7731EB, produced by Texas Instruments, is a 16-bit Digital-to-Analog Converter (DAC) designed to provide high precision and flexibility in various applications. It offers 16 bits of monotonic performance over a specified operating temperature range of –40°C to +85°C and includes a +10V internal reference. The DAC7731EB is particularly suited for automatic test equipment and industrial process control, with the capability to configure its output swing in ±10V, ±5V, or +10V ranges, supporting both unipolar and bipolar operations through pin strapping. The device features a high-speed output amplifier with a maximum 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.
