Dual comparator with 100 ns response — what it means for the signal chain
The Texas Instruments TLV9022DR is a dual general-purpose comparator in an 8-SOIC package. Each comparator delivers an open-drain, rail-to-rail output stage, which lets you wire-OR multiple outputs or translate logic levels between voltage domains without an extra buffer. The 100 ns max propagation delay sets the response window for overcurrent detection, zero-crossing, or window comparators — fast enough for most industrial and automotive sensing loops, though not for GHz-rate switching.
Supply range and quiescent current — sizing the rail
Rated supply from 1.65 V to 5.5 V, single or dual. Max quiescent current per device is 30 µA — both comparators together draw that, not per channel.
Temperature grade and environment
Operating temperature spans -40°C to 125°C, covering industrial motor drives, outdoor telecom cabinets, and automotive under-hood or cabin electronics. No AEC-Q100 qualification is listed in the record, so for a production automotive ECU, confirm the grade with the manufacturer.
Input offset and bias — what the numbers mean for your BOM
Max input offset voltage is 1.5 mV at 5 V. Input bias current maxes at 5 pA at 5 V, so high-impedance sources (pH probes, photodiode front-ends) won't see a significant voltage drop across the source resistance. CMRR is 70 dB typical, PSRR 95 dB typical; these are typical, not guaranteed min, so budget extra margin if the common-mode voltage swings near the rails in a noisy environment.
Output drive and package
Each output can sink 100 mA typical at 5 V — enough to drive a small relay, LED, or logic input directly. The 8-SOIC (3.90 mm width) is a standard footprint, shared by countless op-amps and comparators, so board layout reuse is straightforward. Supplied in Tape & Reel or Cut Tape; surface-mount only.
Lifecycle and sourcing
Product status is Active, ROHS3 compliant. No end-of-life notice or last-time-buy window is on record. The TLV9022DR is sourced through independent distribution and quoted to order against an RFQ; availability and current pricing are confirmed at quote time.
