Industry's First 16-Channel, 14-Bit Dac Rounds Out Analog Devices' Portfolio Of Multichannel Digital-To-Analog Converters

New AD5390 features small CSP package, single 5 V power supply and on-chip reference.

15 May, 2003- Analog Devices has recently added the industry's first 16-channel, 14-bit DAC to its industry-leading portfolio of multichannel digital-to-analog converters (DACs). This new device- the AD5390- comes in a small CSP package, operates from a single 5 V power supply, and contains an on-chip, low-drift reference, eliminating the need for an external reference IC and reducing cost and board space requirements. A 12-bit version- the AD5391- and an 8-channel, 14-bit version- the AD5392- are available as well.
All three high-density devices feature user-programmable offset and gain for digital range adjustment and system calibration, a "boost mode" for faster settling times, and an /LDAC (load DAC) function for simultaneous update of all DAC outputs. In addition, they offer the choice of SPI¹ and I2C serial interfaces and are pin-for-pin compatible, allowing a designer the option of generating different grades of end-product, as appropriate.

Applications
Among many other general-purpose applications, the AD539x multichannel devices are ideally suited for power amplifier control, instrumentation, control systems, and high-resolution control loops.

Pricing and Availability
The AD5390, AD5391 and AD5392 are sampling now in ADI's small 9 mm x 9 mm, 64-lead LFCSP (chip-scale package) and are priced in 1,000-piece quantities at $23.90, $19.90 and $14.90 per unit, respectively.
