Key Features
- Flexible Digital Interface: Data can be loaded in serial mode or as two 8-bit bytes. The serial mode input format is pin selectable to be MSB or LSB first, and the byte mode allows loading of high or low byte data first.
- Double-Buffered Latches: Eliminates data skew errors and allows simultaneous updating of DACs in multiDAC systems.
- On-Chip Output Amplifier: Provides a voltage output settling time of 10 μs to within ±½ LSB for a full-scale step.
- Asynchronous Clear Function: Sets the output to 0 V regardless of the mode (unipolar or bipolar).
- High Precision Voltage Reference: Laser trimmed to 10.000 V with a ±0.1% maximum error and a temperature drift performance of ±15 ppm/°C.
Applications
The AD660BNZ is suitable for a variety of high precision applications, including:
