UAF42AP TI Active Filter | 14-PDIP | Universal, Programmable

Product Overview

The UAF42AP is a universal active filter from Texas Instruments (TI) that can be configured as a low-pass, high-pass, band-pass, or notch filter. It features a state-variable architecture with an operational amplifier and an integrator, allowing precise frequency and Q-factor adjustments. Housed in a 14-pin PDIP package, it is ideal for analog signal processing applications requiring high accuracy and flexibility.
