Description AD5624/AD5664 2.
7 V to 5.
5 V quad, 12-/16-bit DACs, external reference AD5666 2.
7 V to 5.
5 V quad, 16-bit DAC, internal reference, LDAC, CLR pins GENERAL DESCRIPTION The AD5624R/AD5644R/AD5664R, members of the nanoDAC® family, are low power, quad, 12-/14-/16-bit buffered voltageout DACs.
All devices operate from a single 2.
7 V to 5.
5 V supply and are guaranteed monotonic by design.
The AD5624R/AD5644R/AD5664R have an on-chip reference.
The AD56x4R-3 has a 1.
25 V, 5 ppm/°C reference, giving a fullscale output range of 2.
5 V; the AD56x4R-5 has a 2.
5 V, 5 ppm/°C reference giving a full-scale output range of 5 V.
The on-chip reference is off at power-up, allowing the use of an external reference; all devices can be operated from a single 2.
7 V to 5.
5 V supply.
