Description

The DSP101 and DSP102 are high performance sampling analog-to-digital 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 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 standard, low-cost 28-pin plastic DIP packages. Each is offered in two performance grades to match application requirements.
