description
The THS5641A is an 8-bit resolution digital-to-analog converter (DAC) optimized for video applications and
digital data transmission in wired and wireless communication systems. The 8-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 THS5641A offers superior ac and dc performance while supporting update rates up
to 100 MSPS.
The THS5641A operates from an analog and digital supply of 3 V to 5.5 V. Its inherent low power dissipation
of 100 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 17 mW, thereby optimizing the power
consumption for system needs.
The THS5641A 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
THS5641A supports both a straight binary and twos complement input word format, enabling flexible interfacing
with digital signal processors.
