The THS4503 is a high-performance fully differential amplifier from Texas Instruments. The THS4503, without power-down capability, set new performance standards for fully differential amplifiers with unsurpassed linearity, supporting 14-bit operation through 40 MHz. Package options include the 8-pin MSOP with PowerPAD? for a smaller footprint, enhanced ac performance, and improved thermal dissipation capability.
WARNING: The THS4503 may have low-level oscillation when the die temperature (also known as the junction temperature) exceeds 60°C. These devices are not recommended for new designs where the die temperature is expected to exceed 60°C. For more information, see Maximum Die Temperature to Oscillation.
