The TP240x series consists of single, dual, and quad-channel CMOS operational amplifiers featuring low noise and rail-to-rail inputs/outputs optimized for low-power, single-supply applications. Specified over a wide supply range of 2.2 V to 5.5 V, the low quiescent current of only 3.5 mA per channel makes these devices well-suited for power-sensitive applications.

The combination of very low noise (7.3 nV/√Hz at 1 kHz), high gain-bandwidth (20 MHz), and fast slew rate (25 V/μs) make the TP240x family ideal for a wide range of applications, including signal conditioning and sensor amplification requiring high gains. Featuring low THD+N, the TP240x series is also excellent for consumer audio applications, particularly for single-supply systems. The TP2401 is single channel version available in 8-pin SOIC and 5-pin SOT23 packages.

The TP2402 is dual channel version available in 8-pin SOIC and MSOP packages. The TP2404 is quad channel version available in 14-pin SOIC and TSSOP packages.
