description  
The THS5661 is a 12-bit resolution digital-to-analog converter (DAC) specifically optimized for digital data  
transmission in wired and wireless communication systems. The 12-bit DAC is a member of the CommsDAC  
series of high-speed, low-power CMOS digital-to-analog converters. The CommsDAC family consists of pin  
compatible 14-, 12-, 10-, and 8-bit DACs. All devices offer identical interface options, small outline package, and  
pinout. The THS5661 offers superior ac and dc performance while supporting update rates up to 100 MSPS.  
The THS5661 operates from an analog supply of 4.5 V to 5.5 V. Its inherent low power dissipation of 175 mW  
ensures that the device is well-suited for portable and low-power applications. Lowering the full-scale current  
output reduces the power dissipation without significantly degrading performance. The device features a  
SLEEP mode, which reduces the standby power to approximately 25 mW, thereby optimizing the power  
consumption for system needs.  
The THS5661 is manufactured in Texas Instruments advanced high-speed mixed-signal CMOS process. A  
current-source-array architecture combined with simultaneous switching shows excellent dynamic  
performance. On-chip edge-triggered input latches and a 1.2 V temperature-compensated bandgap reference  
provide a complete monolithic DAC solution. The digital supply range of 3 V to 5.5 V supports 3 V and 5 V CMOS  
logic families. Minimum data input setup and hold times allow for easy interfacing with external logic. The  
THS5661 supports both a straight binary and twos complement input word format, enabling flexible interfacing  
with digital signal processors.  
The THS5661 provides a nominal full-scale differential output current of 20 mA and >300 kΩ output impedance,  
supporting both single-ended and differential applications. The output current can be directly fed to the load  
(e.g., external resistor load or transformer), with no additional external output buffer required. An accurate  
on-chip reference and control amplifier allows the user to adjust this output current from 20 mA down to 2 mA,  
withnosignificantdegradationofperformance. Thisreducespowerconsumptionandprovides20dBgainrange  
control capabilities. Alternatively, an external reference voltage and control amplifier may be applied in  
applications using a multiplying DAC. The output voltage compliance range is 1.25 V.
