Frequently Asked Questions
How much output current does each channel of the REF200AU deliver?
Each of the REF200AU's two matched current sources delivers a fixed 100 µA output, with an operating supply range from 2.5 V to 40 V, enabling precise bias generation in analog circuits.
Which package houses the REF200AU's dual current source circuitry?
The REF200AU is housed in an 8-pin small outline package (JESD-30 code R-PDSO-G8), integrating two independent 100 µA current source functions on a single die for compact board layouts.
Why do designers choose matched current sources like the REF200AU for sensor circuits?
Matched dual 100 µA current sources like the REF200AU reduce calibration error in bridge sensor excitation and instrumentation amplifier designs operating across a 2.5 V to 40 V supply range.
