Key Differentiators
- MIL-STD-883 compliance (vs AD667BD)
- Extended temperature range (vs AD667JPZ)
- Hermetic package (vs AD667KN)
Design Notes
The AD667SD/883B requires dual supplies of +5V and -5V. Ensure that both supplies are well-regulated and decoupled with 0.1uF ceramic capacitors placed close to the VCC and VEE pins. A 10uF tantalum capacitor on each supply is recommended for bulk decoupling. The analog and digital grounds should be connected at a single point to minimize noise.
For optimal performance, use a ground plane and separate analog and digital ground areas. Place the DAC close to the load to minimize trace inductance. Keep digital signal traces away from analog output traces to reduce crosstalk. Use short, wide traces for power and ground connections.
Avoid driving the reference output with external loads without buffering, as this can degrade accuracy. Ensure that the digital inputs are not left floating; use pull-up or pull-down resistors as needed. The LDAC pin should be pulsed low to update the output after writing data to the input latch. Failure to do so may result in unexpected output values.
Compliance Information
The AD667SD/883B is not RoHS compliant as indicated in comparison data. It is MIL-STD-883 compliant, indicating military-grade quality.
