REF200AUE4 dual current source/sink ic 100µA 8-SOIC
The REF200AUE4, manufactured by Texas Instruments (formerly Burr-Brown), is a precision dual current source/sink integrated circuit that integrates three independent building blocks on a single monolithic chip: two 100µA current sources and a current mirror . Fabricated using a dielectrically isolated process, each section operates completely independently, allowing the two-terminal current sources to function equally well as either sources or sinks without requiring any power supply or ground connections . Packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with a tube packaging format, this device is designed for surface-mount assembly and provides a floating operation capability that simplifies biasing in complex analog systems . The REF200AUE4 is widely utilized in sensor excitation, biasing circuitry, current loop offsetting, low voltage reference generation, and charge-pump circuits, making it an essential component for precision analog designs requiring stable and accurate current generation .
Engineered for high accuracy and stability, the REF200AUE4 delivers a nominal output current of 100µA per channel with an impressive accuracy of ±0.25% (0.25% max) and a low temperature coefficient of ±25 ppm/°C, ensuring reliable performance across varying thermal conditions . The device operates over a wide compliance voltage range of 2.5V to 40V, providing exceptional flexibility for integration into systems with diverse supply rails . By externally pin-strapping the sections, designers can obtain currents of 50µA, 100µA, 200µA, 300µA, or 400µA, and virtually any current value can be achieved with external circuitry . The device operates reliably over a temperature range of -25°C to +85°C and is RoHS compliant with lead-free termination, supporting environmentally conscious manufacturing processes .
