THS5651A Datasheet | Texas Instruments

he THS5651A is a 10-bit resolution digital-to-analog converter (DAC) specifically optimized for digital data transmission in wired and wireless munication systems. The 10-bit DAC is a member of the ms DAC series of high-speed, low-power CMOS digital-to-analog converters. The ms DAC family consists of pin patible 14-, 12-, 10-, and 8-bit DACs. All devices offer identical interface options, small outline package and pinout. The THS5651A offers superior ac and dc performance while supporting update rates up to 125 MSPS. The THS5651A operates from an analog supply of 4.5 V to 5.5 V. Its inherent low power dissipation of 175 m W 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 m W, thereby optimizing the power consumption for system needs. The THS5651A is manufactured in Texas Instruments advanced high-speed mixed-signal CMOS process. A current-source-array architecture bined with simultaneous switching shows excellent dynamic performance. On-chip edge-triggered input latches and a 1.2 V temperature pensated bandgap reference provide a plete 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 THS5651A supports both a straight binary and twos plement input word format, enabling flexible interfacing with digital signal processors. The THS5651A provides a nominal full-scale differential output current of 20 m A 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...
