- 12-bit resolution with single D/A converter configuration
- Buffered voltage output with external reference architecture
- 5µs settling time performance
- Parallel data interface
- R-2R converter architecture
- ±11.4V to ±15.75V analog supply voltage range
- ±1 LSB maximum INL/DNL specification
- 24-SOIC surface mount package with identical physical dimensions
- Operating temperature range of 0°C to 70°C
- RoHS3 compliance and MSL Level 1 rating
Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or performance degradation.
