DescriptionThe DAC5672A deviceisa monolithic, dual-channel,
14-bit, high-speed DAC with on-chip voltage
reference. ratesof upto 275 MSPS, the dynamic performance, matching characteristics thatin I/Q basebandor direct
Each DAC hasa high-impedance, differential-current
output, suitable for single-ended or differential
analog-output configurations. External resistors allow
scaling the full-scale output current for each DAC
separatelyor together, typically between2 mA and mA. An accurate on-chip voltage referenceis
temperature-compensated and deliversa stable 1.2-V
reference voltage. Optionally, an external reference
may be used.
The DAC5672A has two, 14-bit, parallel input ports
with separate clocks and data latches. For flexibility,
the DAC5672A supports multiplexed data for each
DAC on one port when operatingin the interleaved
mode.
The DAC5672A is specifically designed for a
differential transformer-coupled output witha 50-Ω
doubly-terminated load. Fora 20-mA full-scale output
current,a 4:1 impedance ratio (resultingin an output
powerof4 dBm) and 1:1 impedance ratio transformer
(–2 dBm output power) are supported.
The DAC5672A is available ina 48-pin TQFP
package. Pin compatibility between family members
provides 12-bit (DAC5662) and 14-bit (DAC5672A)
resolutions. Furthermore, the DAC5672A is pin
compatibleto the DAC2904 and AD9767 dual DACs.
The deviceis characterized for operation over the
industrial temperature rangeof –40°Cto 85°C.
