AD5629RBCPZ-1-RL7

Octal, 12-/16-Bit, I2  C, denseDACs  with 5 ppm/°C On-Chip Reference

数模转换器- DAC Octal 12bit I2C w/125V/25V ref

GENERAL DESCRIPTION AD5629RBCPZ-1-RL7

The AD5629R/AD5669R devices are low power, octal, 12-/16-

bit, buffered voltage-output DACs. All devices are guaranteed

monotonic by design.

The AD5629R/AD5669R have an on-chip reference with an

internal gain of 2. The AD5629R-1/AD5669R-1 have a 1.25 V,

5 ppm/°C reference, giving a full-scale output range of 2.5 V.

The AD5629R-2/AD5629R-3 and the AD5669R-2/AD5669R-3

have a 2.5 V 5 ppm/°C reference, giving a full-scale output range

of 5 V depending on the option selected. Devices with 1.25 V

reference selected operate from a single 2.7 V to 5.5 V supply.

Devices with 2.5 V reference selected operate from 4.5 V to 5.5 V.

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.
