Dual comparator with rail-to-rail output in a small SOT-23-8
The Texas Instruments TLV9032DDFR is a dual general-purpose comparator with push-pull rail-to-rail output stages. It operates from a single supply between 1.65 V and 5.5 V.
100 ns propagation delay — what it means for the loop
The maximum propagation delay is 100 ns.
Rail-to-rail output — no pull-up resistor needed
The push-pull rail-to-rail output swings from the negative rail to within millivolts of the positive rail. That eliminates the external pull-up resistor required by open-drain comparators and allows direct connection to CMOS or TTL logic inputs. The output can drive 100 mA at 5 V, so it can also power a small LED or relay coil with a series resistor.
Supply range and quiescent current
Operating from 1.65 V to 5.5 V, the TLV9032DDFR covers the full range of common digital supply voltages. Maximum quiescent current is 30 µA per comparator, which keeps the part suitable for battery-powered instruments and always-on monitoring circuits. Input bias current is 5 pA max at 5 V, so high-impedance sources like photodiode amplifiers or pH probes do not see loading errors.
Sourcing and lifecycle
The TLV9032DDFR is listed as Active in production. No end-of-life notice or last-time-buy window is in effect. For BOM planning, the part is sourced through independent distribution and quoted to order against an RFQ.
