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 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 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.
The outputs of all DACs can be updated simultaneously using
the LDAC function, with the added functionality of user-
selectable DAC channels to simultaneously update. There is
also an asynchronous CLR that clears all DACs to a software-
selectable code—0 V, midscale, or full scale.
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.
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.
