Product details

1.235 V fixed shunt — the reference that set the bench standard

It delivers a stable output with ±2% tolerance and a typical temperature coefficient of 20 ppm/°C, making it a go-to for precision biasing and A/D reference in commercial-temperature designs.

20 mA output, 15 µA cathode — sizing the bias resistor

Rated for 20 mA continuous output current with a cathode current of 15 µA, this shunt reference needs a series resistor sized to supply the load plus the minimum bias current. The 60 µVrms noise spec (10 Hz to 10 kHz) is clean enough for most 8- to 10-bit ADC references in a commercial environment.
