The AD667AE is a monolithic 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features an internal reference voltage source and delivers a buffered voltage output. The device operates with analog supply voltages ranging from ±11.4 V to ±16.5 V and a digital supply of +5 V. Key electrical specifications include a settling time of 3 µs, differential nonlinearity (DNL) of ±0.5 LSB, and integral nonlinearity (INL) of ±0.25 LSB. The part consumes 8 mA of operating current and dissipates 1 W of power. It is housed in a 28-lead plastic DIP package and is rated for operation between -40°C and +85°C.
The AD667AE belongs to the AD667 family of high-speed DACs. This series is characterized by its ability to interface directly with microprocessors and its use of a monolithic R-2R ladder structure. The 'AE' suffix typically denotes specific performance grades or packaging variations within the broader AD667 product line, sharing core architectural features with other variants like the AD667AD and AD667KP.
Direct replacements within the same family include the AD667AD (CDIP package) and AD667JN (PDIP package). When substituting, verify that the pinout compatibility matches the specific package type (e.g., CDIP vs. PDIP) and that the thermal dissipation requirements are met, as power consumption remains constant across the family.
