AD5691RBCPZ-RL7

数模转换器- DAC DAC,nano-14bit w/ref LP, LFCSP

Product Details

The AD5693R / AD5692R / AD5691R / AD5693, members of the nanoDAC+® family, are low power, single-channel, 16-/14-/12-bit buffered voltage output DACs. The devices, except the AD5693, include an enabled by default internal 2.5 V reference, offering 2 ppm/°C drift. The output span can be programmed to be 0 V to VREF or 0 V to 2 × VREF. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The devices are available in a 2.00 mm × 2.00 mm, 8-lead LFCSP or a 10-lead MSOP.

The internal power-on reset circuit ensures that the DAC register is written to zero scale at power-up while the internal output buffer is configured in normal mode. The AD5693R / AD5692R /  AD5691R / AD5693 contain a power-down mode that reduces the current consumption of the device to 2 μA maximum at 5 V and provides software selectable output loads.

The AD5693R / AD5692R / AD5691R / AD5693 use an I2C interface. Some device options also include an asynchronous RESET pin and a VLOGIC pin, allowing 1.8 V compatibility.
