DESCRIPTION
The DSP101 and DSP102 are high performance sam-
pling analog-to-digital converters designed for sim-
plicity of use with modern digital signal processing
ICs. Both are complete with all interface logic for use
directly with DSP ICs, and provide full sampling and
conversion at rates up to 200kHz.
The DSP101 offers a single conversion channel, with
18 bits of serial data output, allowing the user to drive
16-bit, 24-bit, or 32-bit DSP ports. The DSP102 offers
two complete conversion channels, with either two
full 18-bit output ports, or a mode to cascade two
16-bit conversions into a 32-bit port as one word.
Both the DSP101 and DSP102 are packaged in stan-
dard, low-cost 28-pin plastic DIP packages. Each is
offered in two performance grades to match applica-
tion requirements.
