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.","metaTitle":"LM385LPE3-1-2 Shunt Voltage Reference, 1.235 V ±2%, TO-92-3","metaDescription":"LM385LPE3-1-2 fixed 1.235 V shunt reference, ±2% tolerance, 20 mA output, 60 µVrms noise.
