DSP202

® DSP201 DSP202 DSP-Compatible Single/Dual DIGITAL-TO-ANALOG CONVERTERS FEATURES q ZERO-CHIP INTERFACE TO DSP ICs: AD, AT&T, MOTOROLA, TI q SINGLE CHANNEL: DSP201 q DUAL CHANNEL: DSP202 Two Serial Inputs or Cascade from Single 32-Bit Word q UPDATE RATE TO 500kHz q DYNAMIC SPECIFICATIONS: Signal/(Noise + Distortion) = 90dB; THD = –92dB q USER SELECTABLE 16-BIT OR 18-BIT DATA WORDS DESCRIPTION The DSP201 and DSP202 are high performance digital-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 standard, low-cost 28-pin plastic DIP packages. Each is offered in two performance grades to match application requirements.
