AD5664RBRMZ-5REEL7

AD5624R/AD5644R/AD5664R are all nanoDAC® series low-power, four-channel, 12/14/16-bit buffered output digital-to-analog converters (DACs) powered from a single 2.7 V to 5.5 V supply to ensure monotonicity by design.

AD5624R/AD5644R/AD5664R all have an on-chip reference source. The AD56x4R-3 has a built-in 1.25 V, 5 ppm/°C reference with a full-scale output range of 2.5 V; The AD56x4R-5 has a built-in 2.5 V, 5 ppm/°C reference with a full-scale output range of 5 V. When powered on, the on-chip reference is turned off, so an external reference can be used. All devices can be operated from a single 2.7 V to 5.5 V supply. The internal voltage reference is enabled via software write.

The device has a built-in power-on reset circuit that ensures that the DAC outputs 0 V when powered on and maintains that level until a valid write operation is performed. It also features independent shutdown for each channel, reducing the device's power consumption to 480 nA at 5 V in shutdown mode and providing a software-selectable output load. In normal operating mode, the device has low power consumption, making it ideal for portable battery-powered devices.

The AD5624R/AD5644R/AD5664R feature a versatile three-wire serial interface capable of operating at clock rates up to 50 MHz and are compatible with standard SPI, QSPI™, MICROWIRE™, DSP interface standards. It has a built-in on-chip precision output amplifier that enables rail-to-rail output swing.
