Texas Instruments Introduces DAC3484, the Industry’s Most Power-Efficient 4-channel, 16-bit DAC and 1.25 GSPS
Texas Instruments introduced DAC3484, the industry’s most power-efficient 4-channel, 16-bit DAC (digital-to-analog converter). At 1.25 GSPS, the DAC3484 is 25 percent faster than the next fastest quad DAC while consuming as little as 250 mW per channel – 65 percent less than the closest competitor. The DAC3484 is also 40 percent smaller than alternative quad DAC solutions while enabling wideband power amplifier linearization of up to 250 MHz. The wider input bus DAC34H84 or the 2-channel DAC3482 are available to support a linearization bandwidth up to 500 MHz.
“The DAC3484 and its two related DACs can help customers designing 3G, LTE and WiMAX base stations, wideband repeaters and software defined radios optimize their systems for energy efficiency in a smaller footprint.”
Evaluation modules (EVMs) are available now for $499. The DAC3484EVM, DAC3482EVM and DAC34H84EVM include the TRF370315 IQ modulator and CDCE62005 clock jitter cleaner, as well as TI power management devices, such as DC/DC converters and low-noise LDOs, to provide a complete bits-to-RF prototyping and reference design. The EVMs are also compatible with the GC5330SEK, a complete transmit, receive and digital pre-distortion system evaluation kit and reference design for power amplifier linearization.
Additionally, the TSW3100 pattern generation module features a high-speed double data rate LVDS (low-voltage differential signaling) data output bus that provides 16 bits of data at 1.25 GSPS per bit. When combined with the DAC3484EVM, the TSW3100 enables easy data pattern generation while offering a flexible evaluation environment.
The DAC3484 and DAC3482 are sampling today in a 9-mm x 9-mm Multi-row QFN package. Production quantities will be available in 2Q11 for a suggested retail price of $58.60 for the DAC3484 and $33.50 for the DAC3482 in 1,000 unit quantities.
The DAC34H84 is also sampling now in a 12-mm x 12-mm BGA package. Production quantities will be available in 2Q11 for a suggested retail price of $60 in 1,000 unit quantities.
