Overview
The THS7001CPWP is a high-speed programmable-gain amplifier manufactured by Texas Instruments. This device is part of the THS7001 series, which includes single-channel (THS7001) and dual-channel (THS7002) variants. It is designed for applications where load impedance can vary, making it ideal for broadband, high-speed, and power-line communications (HPLC) line-driver applications.
Each channel of the THS7001CPWP consists of a separate low-noise input preamp and a programmable gain amplifier (PGA). The preamp is a voltage-feedback amplifier with a low 1.7-nV/Hz voltage noise and a 100-MHz bandwidth. The PGA offers a digitally controlled gain range from -22 dB to 20 dB with a 6-dB step resolution.
