REF01CSA+

Maxim Integrated · Voltage References · SOIC-8

REF01CSA+ from Maxim Integrated, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 N.C. unconnected No internal connection on the REF01 SO package, so this pin is left unconnected.
2 VIN power_in Positive supply input; the datasheet gives a REF01 input range of 13V to 33V (REF01C: 13V to 30V for line regulation) with an absolute maximum of 40V for REF01E/H and 30V for REF01C.
3 N.C. unconnected Not connected on REF01 (this pin is the TEMP output only on REF02).
4 GND power_in Ground reference pin for the reference output and supply.
5 TRIM input Output-adjust terminal that trims VO by ±6% (±600mV on REF01) with a 10kΩ RP to the output, with only about 0.7ppm/°C tempco change per 100mV of adjustment.
6 VOUT power_out Precision reference output at 10.00V nominal for REF01 (5.000V for REF02), short-circuit protected indefinitely to ground or VIN.
7 N.C. unconnected No internal connection on the REF01 SO package.
8 N.C. unconnected No internal connection on the REF01 SO package.
