ADI AD5627BCPZ-REEL7

The AD5627R/AD5647R/AD5667R, AD5627/AD5667 members of the nanoDAC family are low power, dual, 12-, 14-, 16-bit buffered voltage-out digital-to-analog converters (DACs) with/without on-chip reference. All devices operate from a single 2.7V to 5.5V supply, are guaranteed monotonic by design, and have an I²C compatible serial interface. The AD5627R/AD5647R/AD5667R have an on-chip reference. The AD5627RBCPZ, AD5647RBCPZ, and AD5667RBCPZ have a 1.25V,5ppm/°C reference, giving a full-scale output range of 2.5V; the AD5627RBRMZ and AD5667RBRMZ have a 2.5V,5ppm/°C reference, giving a full-scale output range of 5V. The on-chip reference is off at power-up, allowing the use of an external reference. The internal reference is enabled via a software write. The AD5667 and AD5627 require an external reference voltage to set the output range of the DAC. The AD5627R/AD5647R/AD5667R, AD5627/AD5667 incorporate a power-on reset circuit that ensures the DAC output powers up to 0V, and remains there until a valid write takes place. The device contains a per-channel power-down feature that reduces the current consumption of the device to 480nA at 5V and provides software-selectable output loads while in power-down mode. The low power consumption of this device in normal operation makes it ideally suited to portable battery-operated equipment. The on-chip precision output amplifier enables rail-to-rail output swing. The AD5627R/AD5647R/AD5667R, AD5627/AD5667 use a 2-wire I²C -compatible serial interface that operates in standard (100kHz) fast (400kHz) and high speed (3.4MHz) modes.
