Fourth-generation, low-power TxDAC® digital-to-analog data converters for communications, industrial instrumentation and portable applications
Analog Devices announced the company has developed a low-power generation of its industry-leading TxDACÂ® transmit digital-to-analog converters (DACs). Optimized to the requirements of communications, industrial instrumentation and portable applications that require high-speed performance with the lowest power consumption, Analog Devices' AD970x family reduces power dissipation by up to 70 percent over previous DAC offerings. As a transmit-quality converter, the AD970x family is ideal for applications that need to synthesize broadband signals efficiently- from handheld radios to portable instruments.
"Analog Devices' TxDAC products have become the de facto industry standard for transmit path DACs," said Dave Robertson, product line director of the High-Speed Converter Group at Analog Devices. "These new devices are pin compatible with previous generations of the TxDAC family, enabling designers to take advantage of the dramatic decrease in power dissipation without the need for a costly re-design. The AD9707 family is the latest of a series of new products from ADI focused on lowering overall system cost without performance compromise. It provides the signal path solution while our nanoDACTM family provides low power DACs for level setting and control applications."
More about the AD970x family
All of the devices offer outstanding ac and dc performance and share the same interface, small outline package and pin-out, providing an upward or downward component selection path based on performance, resolution, and cost.
The AD9707 has a flexible power supply operating range from 1.7 V to 3.6 V. At 3.3 V, the AD970x family dissipates 35 mW of power and at 1.8 V dissipates 12 mW. Its power dissipation can be further reduced by 15 mW by lowering the full-scale current output. Sleep and power down modes reduce dissipation to 5 mW for low-power idle periods.
The devices are available in 28-lead TSSOP (thin-shrink small-outline plastic package) and 32-lead LFCSP (lead-frame chip-scale package) packaging. The devices in the LFCSP packaging include an optional SPI (serial peripheral interface), which provides a higher level of programmability, and an adjustable output common mode feature that enables the TxDAC to easily interface to other components that require common modes greater than 0 V. The AD9707 is also self-calibrating, allowing it to achieve greater accuracy and true 14-bit INL (integral nonlinearity) and DNL (differential nonlinearity) performance.
