AD5669RACPZ-3-RL7

The device includes an on-chip reference voltage with an internal gain of 2. The AD5669R-1 contains a 1.25 V, 5 ppm/°C reference with a full-scale output range of 2.5 V; The AD5669R-2 and AD5669R-3 contain a 2.5 V, 5 ppm/°C reference with a full-scale output range of 5 V. At power-up, the on-chip reference is turned off, allowing the use of an external reference. The internal reference voltage is enabled by software writing.

A power-on reset circuit is included to ensure that the DAC output powers up to 0 V and remains at that level until a valid write is performed. There is also an independent power-down feature for each channel, which reduces the power consumption of the device to 400 nA at 5 V in power-down mode and provides a software-selectable output load.

Product features

1. Octal 16-bit DAC.
2. 1.25 V/2.5 V, 5 ppm/ºC on-chip reference.
3. It is available in 16-pin LFCSP and TSSOP packages, and 16-pin WLCSP packages.
4. Power-on reset to 0 V or midscale.
5. Shutdown function. In shutdown mode, the DAC typically consumes 200 nA at 3 V and 400 nA at 5 V.
