The AD5530/AD5531 are single 12- and 14-bit (respectively) serial input, voltage output digital-to-analog converters (DAC). They utilize a negative power supply voltage and have a maximum output voltage range of ±10V. The products have various features, including data readback, clear function, power-down function, etc.
The AD5530 (12‑bit) and AD5531 (14‑bit) are single‑channel voltage‑output digital‑to‑analog converters that use a versatile 3‑wire serial interface compatible with SPI®, QSPI™, MICROWIRE™, and DSP standards. They feature ±10 V output range, data readback, daisy‑chaining, and power‑down capability.
The document lists detailed electrical specifications, absolute maximum ratings, pin descriptions, timing diagrams for standalone and daisy‑chain modes, typical performance curves, application notes such as opto‑isolated interfaces, and ordering information for the 16‑lead TSSOP package.
| Resolution | 12‑bit (AD5530) / 14‑bit (AD5531) |
|---|---|
| Relative Accuracy | ±1 LSB (AD5530) / ±2 LSB (AD5531) |
| Differential Nonlinearity | ±1 LSB (both parts) |
| Power‑Supply Voltage | VDD = +15 V, VSS = –15 V |
| Operating Temperature Range | −40 °C to +85 °C |
The devices use a 3‑wire interface compatible with SPI®, QSPI™, MICROWIRE™, and DSP standards.
LDAC loads the DAC register to update the output asynchronously; it can be tied permanently low to enable continuous updates.
