REF200AU
Brand: Texas Instruments
The REF200AU is a precision matched dual current source — not a voltage reference — delivering two independent 100 µA current sources plus a current mirror on one die with ±0.25% accuracy and no external trim resistor required. Pin-strappable output currents from 50 µA to 400 µA and a 2.5 V to 40 V operating range make it a compact bias-current building block for precision instrumentation.

Analog / Signal Chain Specifications
| Parameter | Value / Specification |
|---|---|
| Channels / Configuration | Dual matched 100 µA current source/current sink plus current mirror (current output, not voltage) |
| Supply Voltage | 2.5 V to 40 V operating voltage |
| Key Performance (Current Accuracy) | ±0.25% current accuracy |
| Package / Case | 8-SOIC (U), 4.9×6.0 mm |
| Output Current Options | Two 100 µA current sources; pin-strappable 50/100/200/300/400 µA currents |
| Operating Temperature | -25°C to +85°C |
| Function | Precision matched current source/sink pair with an internal current mirror — this is a current output device, not a voltage reference |
| Application Note | Generates precise, temperature-stable bias or itation currents rather than a regulated voltage rail |
Analog Features & Applications
- ±0.25% matched current accuracy needs no external trim resistor for precision current sourcing
- Two independent 100 µA current sources plus a current mirror on one die simplify bias-current design
- Pin-strappable output currents (50/100/200/300/400 µA) adapt to different application needs
- 2.5 V to 40 V wide operating-voltage range covers low-voltage to industrial rails
- Laser-trimmed matching between the two current sources aids differential and ratiometric circuits
- 8-pin SOIC package and tube packing suit standard automated assembly
