DIGITAL-TO-ANALOG CONVERTERS

FEATURES

DESCRIPTION

● ZERO-CHIP INTERFACE TO DSP ICs:

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.

● SINGLE CHANNEL: DSP201

● DUAL CHANNEL: DSP202

Two Serial Inputs or Cascade from Single

32-Bit Word

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.

● UPDATE RATE TO 500kHz

● DYNAMIC SPECIFICATIONS:

Signal/(Noise + Distortion) = 90dB;

THD = –92dB

● USER SELECTABLE 16-BIT OR 18-BIT

DATA WORDS

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.
