Product Overview
The LM211 is a Texas Instruments high-speed differential comparator in the Signal_Chain category. It is specified for a recommended VCC+ to VCC- supply voltage range of 3.5 to 30 V, with an absolute maximum supply differential of 36 V. For ±15 V operation, the datasheet lists an input voltage range from VCC- + 0.5 V to VCC+ - 1.5 V when |VI| is no greater than 15 V.
Input specifications include 2 mV typical and 7.5 mV maximum input offset voltage at 25 °C, and up to 10 mV across the full LM211 temperature range. The device is also specified for 6 nA typical input offset current, 100 nA typical input bias current, and a -14.5 V to 13.8 V common-mode input voltage range on ±15 V supplies.
Output-related ratings include a 50 V LM211 collector output voltage to VCC- absolute maximum and a 30 V emitter output voltage to VCC- absolute maximum. Package options listed for this part include SOIC(8), PDIP(8), and TSSOP(8), supporting comparator use in threshold detection, differential sensing, strobe-controlled operation, and switching-interface circuits.

Procurement Notes
When requesting a quote for LM211, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
