Overview
The DAC7741YB/250G4 is a 16-bit Digital-to-Analog Converter (DAC) produced by Texas Instruments. It offers 16 bits of monotonic performance over a specified operating temperature range and features a +10V, low-drift internal reference. This DAC is designed for applications such as automatic test equipment and industrial process control. The output swing can be configured in ±10V, ±5V, or +10V ranges, allowing for both unipolar and bipolar operation through pin strapping. The device includes 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.
