Parallel input bus for straightforward, high-throughput data feeding

Digital IO compatible with 1.8 V logic levels

Analog supply 3.0 to 3.6 V. Digital supply 1.7 to 1.9 V

Settling time 10.4 ns typical for fast waveform updates

Differential output capability reduces common-mode noise and improves SNR

Operating temperature range -40 C to 85 C for industrial environments

Supplier device package 64-VQFN 9 mm x 9 mm with exposed pad

Tape and Reel packaging for automated pick-and-place

Key Advantages

High linearity and precision enable clean spectral performance in RF and instrumentation

Dual outputs simplify IQ modulation and multi-channel systems

Flexible reference modes support tight calibration and system-level optimization

Low 1.8 V digital supply reduces power and heat

Exposed thermal pad improves heat dissipation and reliability under load

Compact 9 mm x 9 mm package saves PCB space without sacrificing performance

Backed by TI’s mature documentation and tools, supported by Y-IC’s sourcing and service

Packaging

Type 64-pin VQFN with exposed thermal pad

Size approximately 9 mm x 9 mm body, low-profile height suitable for dense layouts

Material molded epoxy encapsulation and copper leadframe with lead-free plating. RoHS3 compliant

Pin configuration parallel data bus pins, control and clock pins, separate analog and digital supply pins, reference pins for internal or external reference selection, differential current outputs for DAC A and DAC B, multiple ground pins, central exposed pad for thermal and electrical ground

Thermal characteristics exposed pad significantly lowers thermal resistance when soldered to a grounded copper plane. Use thermal vias under the pad to spread heat into inner layers. Follow TI land pattern and reflow profile for QFN packages for optimal solder wetting

Electrical properties output type current sink unbuffered. Analog supply 3.0 to 3.6 V. Digital supply 1.7 to 1.9 V. Differential outputs supported. Typical settling time 10.4 ns. INL ±4 LSB. DNL ±2 LSB

Mounting type surface mount. Package codes 64-VQFN 9x9 RGC. Package and case 64-VFQFN exposed pad. Supplier device package 64-VQFN 9x9
