Product Overview
DAC0808LCMX/NOPB is a classic 8-bit current-output DAC. Instead of producing a buffered voltage directly, it steers a reference-defined current so the designer can choose the external current-to-voltage conversion and output range.
The 150 ns typical settling time is fast for a simple 8-bit architecture and makes the part useful in waveform generation, servo/control and legacy replacement designs. Relative accuracy of the LC grade supports monotonic 8-bit behavior when reference and output circuitry are appropriate.
Because output current and reference network are exposed, board-level op-amp choice, compliance voltage and reference quality strongly influence the final voltage-output performance. The LCMX/NOPB code is the active 2500-piece SOIC reel.

Functional Highlights
Current output gives flexible scaling and multiplying behavior
Changing reference current changes full-scale output without rewriting digital codes, useful in programmable gain or multiplying-DAC circuits.
External I/V stage determines the usable voltage output
The DAC itself does not provide a low-impedance buffered voltage. Op-amp bandwidth, settling and compliance must match the 150 ns converter behavior.
Design Considerations
- Select the I/V amplifier for settling, output swing and input-current requirements.
- Keep the DAC output node within its compliance limits while the current changes.
- Use a stable low-noise reference if absolute gain accuracy matters.
