REF5050AIDR

REF5050AIDR is the tape-and-reel SOIC-8 ordering code for the Texas Instruments REF5050 voltage reference, listed as ACTIVE in the datasheet package option addendum. This is the standard AI grade on its own electrical rows - not the tighter I grade of the same family - with an initial accuracy of -0.1 % to +0.1 %, a temperature drift of 3 ppm/°C typical and 8 ppm/°C maximum, output noise of 15 µVpp in the 0.1 Hz to 10 Hz band, a quiescent current of 0.8 mA typical and 1 mA maximum, an output current of ±10 mA, and a supply window from 0.2 V above the 5.0 V output up to 18 V, over -40 °C to +125 °C. The selection point is a 5 V reference rail for precision data converters and analogue front ends where the drift ceiling, not the headline accuracy, closes the system error budget. Selection advice: the REF50 family interleaves two accuracy grades and several output voltages under similar codes, so quote REF5050AIDR in full and check the packing against the addendum - a same-family offer at a different grade changes the drift budget materially. Parameters verified against the TI REF5050 datasheet SBOS410 (package option addendum and the standard-grade electrical table).
