GENERAL DESCRIPTION
0.1
The DAC16 is a 16-bit high speed current-output digital-to-
analog converter with a settling time of 500 ns. A unique com-
bination 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 full-
scale output current of 5 mA. The 16-bit parallel digital input
bus is TTL/CMOS compatible. Operating from +5 V and
鈥?5 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.
