AD3531RBCBZ-RL7

AD3531RBCBZ-RL7 is a low power, 4-channel, 16-bit, buffered voltage output, digital-to-analogue converter (DAC) that include software-programmable gain controls that result in full-scale output spans of 2.5V or 5V for reference voltages of 2.5V. The devices operate from single, 2.7V to 5.5V supply ranges and are guaranteed monotonic by design. The AD3531R also offers a 2.5V, 5ppm/°C internal reference that is disabled by default. The devices include integrated multiplexers that allow monitoring of output voltages, currents, and internal die temperature. The device incorporates power-on reset (POR) circuits that ensure that the DACs output power up to and present at 16kΩ to ground until a valid write is executed. The DACs also contain power-down modes that reduce the current consumption down to 620μA, typical. The serial peripheral interface (SPI) and MICROWIRE®-compatible, 4-wire serial interface operates on logic levels as low as 1.08V up to 1.98V and clock rates up to 50MHz.
