TLV990-28PFB TI Analog Front End | 48-TQFP (7x7) | 28-Bit, 1MSPS

Product Overview

The TLV990-28PFB from Texas Instruments is a high-performance analog front-end (AFE) IC designed for precision data acquisition systems. Housed in a compact 48-pin TQFP (7x7 mm) package, this device integrates a 28-bit delta-sigma ADC, programmable gain amplifier (PGA), and voltage reference, making it ideal for applications requiring high resolution and low noise. With a sampling rate of up to 1 MSPS, it bridges the gap between high-speed and high-accuracy conversion.
