Overview
The THS4520RGTRG4, produced by Texas Instruments, is a wideband, fully differential operational amplifier designed for high-performance data acquisition systems. It is particularly suited for applications requiring low noise, low distortion, and high accuracy. The amplifier operates over a supply voltage range of 3.3V to 5V and is characterized for operation over the full industrial temperature range from -40°C to 85°C. It features a rail-to-rail output and independent output common-mode control, making it ideal for driving high-speed and high-resolution analog-to-digital converters (ADCs).
