🛠️ DAC8800BR / 883C Overview
Both are part of the DAC‑8800 (TrimDAC®) family: 8-bit, octal (8-channel) CMOS DACs in a 20-pin CDIP package with a 3‑wire serial interface.
🔍 Key Features
| Feature | Specification |
|---|---|
| Resolution & Channels | 8 bits, 8 separate DACs |
| Interface | 3‑wire serial (SPI‑compatible); loads 8 registers |
| Output Range | Programmable unipolar/bipolar via external V_REF_H/L |
| Settling Time | Fast: ~2 µs to within ½ LSB |
| Accuracy | ±½ LSB TUE, guaranteed monotonic operation |
| Power | Low digital standby current (< 20 µA); single or dual supply |
| Operating Range | V_DD = 2.7–5.5 V; V_REF as needed for ± range |
| Operating Temp | –55 °C to +125 °C |
⚙️ Functional Highlights
-
TrimDAC® design: Load 8 internal 8-bit registers; asynchronous CLR resets outputs to zero.
-
Serial loading: Requires 8 x 8-bit words; loads simultaneously on chip-select toggle .
-
Flexible configuration: You set each channel’s output range with external reference voltages.
✅ Good For
-
Precision trimming (offset/gain adjustments)
-
Multi-channel analog control (e.g., programmable supplies, actuator drivers)
-
Instrumentation with bipolar/unipolar output needs
-
Environments demanding high thermal range and reliability
