Description
The DAC161S997RGHT is a 16-bit, single-channel digital-to-analog converter (DAC) from Texas Instruments, designed for 4–20 mA current loop applications in industrial systems. It features a serial peripheral interface (SPI) for communication and includes an integrated voltage reference for high accuracy (±0.1% max INL).
Key features:
- 16-bit resolution with low drift (±2 ppm/°C).
- 4–20 mA or 0–20 mA output with loop power supply (up to 40 V).
- Self-diagnostic functions (open/short-circuit detection).
- Low power consumption (3.3 V or 5 V supply).
Packaged in a VQFN-16 (RGHT), it’s ideal for process control, PLCs, and smart transmitters. Its robust design ensures reliable performance in harsh environments.
