AD531x, AD568x, and AD569x nanoDAC®

Analog Devices introduces a second series of quad 10-, 12-, and 16-bit 3 V/5 V D/A converters in space-saving 16-lead LFCSP and TSSOP packages. These new AD531x/AD568x/AD569x nanoDAC+™ quad D/A converters offer the industry’s best DC performance (INL is ±2LSB max, offset error is ±1.5 mV max and gain error is ±0.1% max) in the smallest package (3 mm x 3 mm LFCSP), with SPI or I²C interface options. Applications such as PLC (programmable logic controller) I/O cards, digital oscilloscopes, signal generators, and optical modules that require low power, rail-to-rail, single-supply D/A converters will benefit from the AD568x/9x series’ industry-leading performance.

The AD531x members of the nanoDAC® family are low power, single-channel, 10-bit buffered voltage-out DACs. The devices include a 2.5 V, 2 ppm/°C internal reference. The output span can be programmed to be 0 V to VREF or 0 V to 2 × VREF. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The devices are available in 10-lead MSOP packages.

The AD5680, a member of the nanoDAC® family, is a single, 18-bit buffered voltage-out digital-to-analog converter that operates from a single 4.5 V to 5.5 V supply and is 18-bit monotonic. The AD5680 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V (AD5680-1) or to mid-scale (AD5680-2) and remains there until a valid write takes place.

The AD5694, a member of the nanoDAC+™ family, is a low-power, quad, 16-bit buffered voltage output DAC. The device includes a gain-select pin giving a full-scale output of 0 V to VREF (gain = 1) or 0 V to 2.0 VREF (gain = 2). The device operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP package and a TSSOP package.
