Push-pull output and what it saves on the BOM
The TLV7211AID: The output swings rail-to-rail, so it drives logic inputs directly without a level-shift resistor divider. Propagation delay is 10 µs max — this is a slow comparator by modern standards, suited for threshold detection, overvoltage/undervoltage monitoring, and zero-crossing at line frequencies rather than high-speed PWM or switching-regulator feedback loops.
Supply flexibility and power budget for battery-operated designs
Input bias current is 0.04 pA typ at 5 V — essentially zero for practical circuits. A 10 MΩ source impedance drops only 0.4 µV across the input, preserving accuracy in high-impedance sensor front-ends like pH probes or photodiode amplifiers.
Temperature range and industrial deployment
CMRR is 75 dB typ and PSRR is 80 dB typ, giving reasonable rejection of common-mode noise and supply ripple in noisy industrial environments. Input offset voltage is 5 mV max at 5 V — acceptable for general-purpose threshold detection but not precision instrumentation. For sub-mV resolution, a zero-drift or chopper-stabilized comparator would be needed.
Available in tube packaging — the tube quantity is typically 95 or 100 pieces per tube for SOIC-8, suitable for prototype builds and low-volume production without reel fees.
Active lifecycle and compliance status
ROHS3 compliant, meaning no restricted substances above threshold limits, and it ships with full TI traceability and warranty through authorized distribution.
