AD5664RBRMZ-3REEL7 数模转换器

AD5664RBRMZ-3REEL7

Quad, 12-/14-/16-Bit nanoDACs with  5 ppm/°C On-Chip Reference

数模转换器- DAC Quad 16-Bit w/ 5ppm/oC on chip ref

GENERAL DESCRIPTION AD5664RBRMZ-3REEL7

The AD5624R/AD5644R/AD5664R, members of the nanoDAC®

family, are low power, quad, 12-/14-/16-bit buffered voltage-out

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. The internal reference is enabled via a software

write.
