DALLAS (Sept. 30, 1998) -- The industry's fastest family of voltage-output digital-to-analog converters (DACs) has gained three new high-speed products, Texas Instruments (TI) announced today. The new digital-to-analog converters, the fastest voltage-output DACs with serial interfaces on the market, bring unique programmability and a glueless interface capability to the design of systems based on TI's TMS320 digital signal processors (DSPs) and a variety of industry microcontrollers.

The TLV5604, TLV5614, and TLV5616 operate with supply voltages of 2.7 to 5.5 V, and offer flexibility in designing a wide range of stationary and mobile systems. Applications that will benefit include office equipment, cordless and wireless telephones, telecom line cards, mass storage devices, digitally controlled filters, and industrial process control, machine and motion control, and battery-powered test instruments.

"As the world leader in both the DSP and analog/mixed-signal markets, TI is committed to providing system designers the data converters they need for seamless implementation of DSP systems," said Tom Lahutsky, new product development manager for TI's data converter products. "TI's DAC portfolio gives designers the programmability, speed, easy interface, small packaging, and advanced process technology they need to optimize their DSP solutions."

High Speed and Design Flexibility

The three new devices offer a range of data conversion capabilities and numbers of on-chip DACs. The TLV5604 integrates four 10-bit DACs, the TLV5614 four 12-bit DACs, and the TLV5616 a single 12-bit DAC. With a one microsecond typical settling time, the devices are the fastest 10- and 12-bit voltage-output DACs with serial interfaces available today.

The converters were designed for flexibility, low power consumption, and space savings in system design. All three devices feature an easy-to-use four-wire serial bus that interfaces gluelessly to TMS320 DSPs and microcontrollers using SPI, QSPI, and Microwire™ buses. In fact, they are the only serial voltage-output DACs that can be used directly with TI DSPs, providing a unique convenience for the design of TMS320 systems.

System designers can trade off speed versus power consumption in either 3- or 5-V systems by using a unique feature for programming settling time. A buffered reference input allows the devices to use all the reference voltages in the specified voltage range. A rail-to-rail buffered voltage-output stage increases voltage swing and eliminates the need for an amplifier stage. When the DACs are not converting data, a power-down mode is available to save additional power.

Packaging, Availability, Pricing

Packaging of the new DAC devices is designed to save board space, with 16-pin small outline IC (SOIC) and thin small-scale outline (TSSOP) packages offered for both the '5604 and '5614, and an 8-pin SOIC package offered for the '5616.

The '5604, '5614, and '5616 are all available today from TI and TI's authorized distributors.
