The DAC16 is 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 in a 24-lead epoxy DIP, epoxy surface-mount small
outline (SOL), and in die form.
