Overview
The THS3110IDR is a low-noise, high-voltage, current-feedback operational amplifier produced by Texas Instruments. This amplifier is designed to operate over a wide supply range of ±5 V to ±15 V, making it suitable for various high-performance applications. It features a power-down pin that allows the amplifier to enter a low-power standby mode, significantly reducing the quiescent current. The THS3110IDR is available in SOIC-8 and MSOP-8 packages with PowerPAD™, enhancing thermal performance.
