What this dual nanopower comparator brings to the board
The Texas Instruments TLV3702IDR is a dual general-purpose comparator with CMOS push-pull rail-to-rail outputs. Its max quiescent current is 1 µA per channel. With 88 dB CMRR and 105 dB PSRR, this part rejects supply ripple and common-mode noise well enough for threshold detection in noisy industrial environments. The -40°C to 125°C operating range covers engine bays, rooftop telecom enclosures, and factory-floor cabinets without derating.
Sourcing and lifecycle — no LTB worry here
No last-time-buy clock ticking, no forced redesign for an obsolescence notice. ROHS3 compliant, which keeps it clean for EU and global BOMs.
What the ratings mean for a field swap or new design
The 1 µA max quiescent current is the headline number. In a battery-powered sensor that sleeps most of the time, that is the difference between a year of runtime and a battery change every quarter. The 10 mA output current per channel is enough to drive a logic input or a small LED directly — no extra buffer transistor needed on the board. Input offset voltage is specified at 5 mV max at 15 V supply. The 8-SOIC package is a standard footprint — easy to hand-solder in a pinch, no hot-air station required.
