Voltage-output octal DACs

13 March 2002 Analogue, Mixed Signal, LSI

Analog Devices has introduced a family of octal 8, 10 and 12-bit buffered voltage-output digital-to-analog converters (DACs) that operate from a single 2,5- to 5,5 V power supply and consume only 1,4 mA at 3 V. Rail-to-rail outputs provide maximum headroom and dynamic range in low-voltage, single supply applications. The 8-bit AD5308, 10-bit AD5318 and 12-bit AD5328 have a three-wire serial interface that operates at clock rates up to 30 MHz. Integrating eight DACs on one chip, these converters are designed for space-constrained applications. Power-down feature reduces the current consumption to 400 nA at 5 V (120 nA at 3 V). Each of the eight DAC channels can be individually powered-down for flexible and incremental power management. Data is entered as a

16-bit word consisting of one control bit, three address bits, and 12 data bits. The AD53x8 family operates from -40 to 105°C and is available in 16-lead TSSOP package.
