GENERAL DESCRIPTION

The AD5678 is a low power, octal, buffered voltage-output

DAC with four 12-bit DACs and four 16-bit DACs in a single

package. All devices operate from a single 2.7 V to 5.5 V supply

and are guaranteed monotonic by design.

The outputs of all DACs can be updated simultaneously using

the function, with the added functionality of user-

LDAC

selectable DAC channels to simultaneously update. There is

also an asynchronous that clears all DACs to a software-

CLR

selectable code—0 V, midscale, or full scale.

The AD5678 has an on-chip reference with an internal gain of 2.

The AD5678-1 has a 1.25 V 5 ppm/°C reference, giving a full-

scale output of 2.5 V; the AD5678-2 has a 2.5 V 5 ppm/°C

reference, giving a full-scale output of 5 V. The on-board

reference is off at power-up, allowing the use of an external

reference. The internal reference is enabled via a software write.

The AD5678 utilizes a versatile 3-wire serial interface that

operates at clock rates of up to 50 MHz and is compatible with

standard SPI®, QSPI™, MICROWIRE™, and DSP interface

standards. The on-chip precision output amplifier enables rail-

to-rail output swing.

The part incorporates a power-on reset circuit that ensures that

the DAC output powers up to 0 V and remains powered up at

this level until a valid write takes place. The part contains a

power-down feature that reduces the current consumption of

the device to 400 nA at 5 V and provides software-selectable

output loads while in power-down mode for any or all DAC

channels.

PRODUCT HIGHLIGHTS

1. Octal DAC (four 12-bit DACs and four 16-bit DACs).

2. On-chip 1.25 V/2.5 V, 5 ppm/°C reference.

3. Available in 14-lead/16-lead TSSOP.

4. Power-on reset to 0 V.

5. Power-down capability. When powered down, the DAC

typically consumes 200 nA at 3 V and 400 nA at 5 V.
