The VCA820IDGSR from Texas Instruments is a dc-coupled, wideband, linear in dB, continuously variable, voltage-controlled gain amplifier. It provides differential input to single-ended conversion with a high-impedance gain control input. The gain can be varied down by more than 40 dB from the nominal maximum gain.
Key electrical specifications include a small-signal bandwidth of 150 MHz and a 5-V PP bandwidth of 137 MHz at a gain of +10 V/V. It features a high slew rate of 1700 V/µs and a gain accuracy of ±0.4 dB at 20 dB. The amplifier operates from supply voltages between 7V and 12V and offers a high output current of 160 mA.
The internal architecture consists of input buffers and an output current feedback amplifier stage integrated with a multiplier core, eliminating the need for external buffering. The maximum gain is set externally using two resistors, providing design flexibility. The device is suitable for applications such as AGC receivers with RSSI, differential line receivers, pulse amplitude compensation, and variable attenuators.
Available in SOIC (D) and VSSOP (DGS) packages, the VCA820IDGSR is designed for surface mount applications. Its operating temperature range is -40°C to 85°C.
