DESCRIPTION
The DSP201 and DSP202 are high performance digi-
tal-to-analog converters designed for simplicity of use
with modern digital signal processing ICs. Both are
complete with all interface logic for use directly with
DSP ICs, and provide analog output voltages updated
at up to 500kHz.
The DSP201 offers a single complete voltage output
channel, accepting either 16 bits or 18 bits of input
data, and can be driven by 16-bit, 24-bit, or 32-bit
serial ports. The DSP202 offers two complete voltage
output channels, with either two separate input ports,
or a mode to drive both output channels from a single
32-bit word.
Both the DSP201 and DSP202 are packaged in stan-
dard, low-cost 28-pin plastic DIP packages. Each is
offered in two performance grades to match applica-
tion requirements.
