AD5501 is a single channel 12-bit high voltage DAC with selectable 30 V or 60 V output range, integrated precision reference, low power serial interface with readback capability, integrated temperature sensor alarm function, power-on reset, wide operating temperature range:-40°C to +105°C. Applications include programmable voltage sources, high voltage LED drivers, receiver bias in optical communications.
The AD5501 is a single-channel, 12-bit serial input digital-to-analog converter (DAC) featuring an on-chip high voltage output amplifier and an integrated precision reference. The device offers a programmable output voltage range of either 0 V to 30 V or 0 V to 60 V via the R_SEL pin.
The AD5501 includes a high-speed serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards, supporting clock speeds up to 16.667 MHz. It features an integrated temperature sensor that triggers an alarm if the die exceeds 110°C, entering a power-down mode to prevent short-circuit conditions.
