For ongoing production, you will want to qualify a pin-compatible alternative or secure a final buy lot through independent distribution. ## Adjustable shunt reference — 1.24 V to 5.3 V The LM385M is a shunt-type voltage reference with an adjustable output from 1.24 V to 5.3 V, set by two external resistors. The ±2% initial tolerance and 150 ppm/°C temperature coefficient are adequate for general-purpose biasing and low-to-mid accuracy ADC references. The 50 µVrms noise (10 Hz to 10 kHz) is clean enough for 12-bit systems if the bandwidth is limited. ## Output drive and cathode current The shunt can sink up to 20 mA, which covers most reference loads — op-amp bias, comparator thresholds, or a small pull-up. ## Sourcing for production and repair Because this part is NRND, standard distribution stock may thin out. If you are stocking spares for existing boards, this is the right part. For new designs, look at the LM385 family in an active package variant.","metaTitle":"LM385M Adjustable Shunt Voltage Reference, 1.24V–5.3V","metaDescription":"LM385M adjustable shunt voltage reference, 1.24 V to 5.3 V output, ±2% tolerance, 50 µVrms noise, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Tolerance":"±2%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Not For New Designs","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"20 mA","Current - Supply":"-","Current - Cathode":"55 µA","Base Product Number":"LM385","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"50µVrms","Operating Temperature":"0°C~70°C(TA)","Voltage - Output (Max)":"5.3 V","Supplier Device Package":"8-SOIC","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7814","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4199e8d59659e82b20c871ef2cbe4629.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM385M/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to LM385M?","answer":"Within the LM385 family, the LM385Z in a TO-92 package is a through-hole alternative with the same electrical characteristics.
