Product Overview
Output behavior is analog and push-pull, with ±50 µA output drive capability and short-circuit protection. Supply current is specified at a typical 5.4 µA, with maximum values of 8.1 µA for TA = 30 °C to 150 °C and 9 µA across TA = -50 °C to 150 °C, under VDD - VOUT ≥ 100 mV conditions. Output load capacitance is specified up to 1100 pF, and power-on time is typically 0.7 ms with a 1.9 ms maximum for CL = 0 pF to 1100 pF.
Package choices cover SOT/SC70 5-pin surface mount, TO-92 straight or formed leads, and TO-92S straight leads. Pin functions include OUT for the inverse temperature voltage, VDD for positive supply, and GND for supply ground, with pin assignments varying by package.

Procurement Notes
When requesting a quote for LMT84, 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.
