DAC908E

DAC908E is a 12‑bit multiplying digital-to-analog converter (DAC) in the DAC908 family. It converts a 12‑bit digital word into an analog output that is proportional to both the code and a reference signal, enabling precise programmable gain and calibration.
Key points:
- Resolution: 12 bits; monotonic with high linearity.
- Multiplying DAC: full-scale output scales with the reference (Vref or Iref), giving flexible output ranges.
- Architecture: typically a current-output DAC that requires external I→V conversion (op-amp and feedback resistor) to produce a voltage.
- Interface: usually parallel 12‑bit input (some variants offer serial interfaces); check exact device alternate.
- Performance: fast settling, low glitch, suitable for instrumentation and control loops; available in extended temperature grades (the “E” variant).
Typical uses: programmable gains, calibration systems, waveform generation, and precision control loops.
Note: Pinout, Iout/Vout relationship, reference requirements, and timing are device-specific. Always consult the latest DAC908E datasheet for exact specs.

There’s no widely published direct cross-reference for DAC908E. To find equivalents, specify package, supply, and interface. For functional substitutes, use 8‑bit multiplying DACs with similar interfaces, e.g., TI DAC0800 (and successors) or Analog Devices DAC08x/DAC80x families; verify pinout, reference, and output type. For a guaranteed drop‑in, request a cross‑reference from the supplier.

Pin count: 16 pins (DIP/SOIC variants).
Function: An 8‑bit multiplying digital‑to‑analog converter with current output (Iout), producing a current proportional to the digital input times the reference; typically used with an external op-amp to convert to a voltage.

Manufacturer: Analog Devices, Inc. (ADI).
