The VCA821ID from Texas Instruments is a DC-coupled, wideband, linear in dB, continuously variable, voltage-controlled gain amplifier. It provides a differential input to single-ended conversion with a high-impedance gain control input. The device offers a > 40-dB gain adjust range, allowing for significant gain variation from the nominal maximum.
Key electrical specifications include a 710 MHz small-signal bandwidth at G = +2 V/V and a 320 MHz bandwidth at G = +10 V/V. It boasts a high slew rate of 2500 V/µs and a gain accuracy of ±0.3 dB at 20 dB gain. The amplifier operates from a supply voltage range of ±7 V to ±12 V and has a typical quiescent current per channel of 34 mA. The maximum gain is typically set between 6 dB and 32 dB externally.
Available in SOIC (D) and VSSOP (DGS) packages, the VCA821ID is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, making it robust for various environmental conditions. The device is designed for applications requiring precise gain control and high bandwidth.
