Overview
The THS3201DGNR, manufactured by Texas Instruments, is a high-performance, wideband current-feedback amplifier. This device is designed to operate over a wide supply range of ±3.3 V to ±7.5 V, making it suitable for various high-performance applications. The THS3201 is known for its high slew rate of 6700 V/µs and low distortion, particularly with an IMD3 of –78 dBc at 20 MHz. These characteristics make it ideal for driving high-resolution and high-sampling rate analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), as well as for test, measurement, and automated test equipment (ATE) applications.
