LMH32404IRHFR TI Transimpedance Amplifier | 28-VQFN (5x4) | 4-Ch, 2.8GHz GBW

Product Overview

The LMH32404IRHFR is a high-performance, 4-channel transimpedance amplifier (TIA) from Texas Instruments, designed for optical sensing applications requiring wide bandwidth and low noise. Housed in a compact 28-pin VQFN (5x4 mm) package, this device integrates four independent TIA channels, each capable of converting photodiode current into a voltage output with minimal distortion. With a gain bandwidth product of 2.8 GHz and input-referred noise as low as 1.8 pA/√Hz, the LMH32404 is ideal for high-speed optical receivers in data communications, LiDAR, and test equipment.
