GENERAL DESCRIPTION

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

–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.
