Two nanopower comparators in an 8-SOIC — what the 1.2 µA quiescent buys you
The Texas Instruments TLV3492AIDR packs two general-purpose comparators into an 8-SOIC package, each drawing a maximum 1.2 µA quiescent current. The push-pull rail-to-rail output stage eliminates the external pull-up resistor needed on open-drain comparators, saving a component and a PCB trace.
13.5 µs propagation delay — budgeting the signal chain
The 13.5 µs maximum propagation delay sets the comparator's response time from overdrive to output transition. For a window comparator monitoring a 10 kHz signal, that delay eats about 13.5° of phase — acceptable for most threshold alarms but something to model if you're closing a control loop. The 10 pA typical input bias current at 5.5 V means negligible loading on high-impedance sensor outputs, so the divider network or thermistor bridge doesn't need a buffer.
15 mV input offset — the trip-point guard band
Maximum input offset voltage is 15 mV at 5.5 V. When setting a precision threshold — say a 100 mV reference on the non-inverting input — budget at least 15 mV of hysteresis or guard band to avoid chatter at the trip point. The 74 dB CMRR and 69.12 dB PSRR are adequate for supply-rail sensing and general-purpose level detection but don't target the microvolt-resolution comparator class.
