TL331LVQDBVRQ1

Comparators Overview

The TL331LVQDBVRQ1 is a single-channel analog comparator from the TL331LV series, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and consumes a typical operating supply current of 26 uA. The device features rail-to-rail input capability and an open-drain output type. Key electrical specifications include a maximum input offset voltage (Vos) of 400 uV, an input bias current (Ib) of 5 pA, and an input offset current (Ios) of 1 pA. Propagation delay is specified at 600 ns, with a power supply rejection ratio (PSRR) of 80 dB. It is housed in a SOT-23-5 package and supports an operating temperature range from -40°C to +125°C.
