TLV990-21PFB TI Analog Front End | 48-TQFP (7x7) | 3V, 12-bit

Product Overview

The TLV990-21PFB is a high-performance analog front-end (AFE) IC from Texas Instruments, designed for precision signal conditioning in imaging and sensor applications. Housed in a compact 48-pin TQFP (7x7 mm) package, it integrates a 12-bit analog-to-digital converter (ADC), programmable gain amplifier (PGA), and correlated double sampling (CDS) circuitry. Operating from a single 3V supply, it delivers low noise and high dynamic range, making it ideal for CCD/CIS image sensors, medical imaging, and industrial inspection systems.
