FEATURES 1 LSB Differential Linearity (max) Guaranteed Monotonic Over Temperature Range 2 LSB Integral Linearity (max) 500 ns Settling Time 5 mA Full-Scale Output TTL/CMOS Compatible Low Power: 190 mW (typ) Available in Die Form APPLICATIONS Communications ATE Data Acquisition Systems High Resolution Displays

The a 16-bit high speed current-output digital-toanalog converter with a settling time of 500 ns. A unique combination of low distortion, high signal-to-noise ratio, and high speed make the DAC16 ideally suited to performing waveform synthesis and modulation in communications, instrumentation, and ATE systems. Input reference current is buffered, with fullscale output current of 5 mA. The 16-bit parallel digital input bus is TTL/CMOS compatible. Operating from +5 V and �15 V supplies, the DAC16 consumes 190 mW (typ) and is available a 24-lead epoxy DIP, epoxy surface-mount small outline (SOL), and in die form.

1. Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation at or above this specification is not implied. Exposure to the above maximum rating conditions for extended periods may affect device reliability. 2. Digital inputs and outputs are protected; however, permanent damage may occur on unprotected units from high energy electrostatic fields. Keep units in conductive foam or packaging at all times until ready to use. Use proper antistatic handling procedures. 3. Remove power before inserting or removing units from their sockets.

NOTE JA is specified for worst case mounting conditions, i.e., JA is specified for device in socket.
