VCA821IDGST Description

The VCA821IDGST from Texas Instruments is a high-performance variable gain amplifier (VGA) designed for precision signal conditioning in wideband applications. Packaged in a compact 10-VSSOP surface-mount form factor, this IC delivers exceptional bandwidth and linearity, making it ideal for RF, medical imaging, and test equipment. Operating within a 7V to 12V supply range, it features a 710 MHz bandwidth, 2500 V/µs slew rate, and 90 mA output current, ensuring robust performance in dynamic signal environments. With low input bias current (19 µA) and 4 mV input offset voltage, it minimizes distortion while maintaining signal integrity.

VCA821IDGST Features

• Wideband Performance: 710 MHz -3dB bandwidth supports high-frequency applications.
• High Slew Rate: 2500 V/µs enables rapid signal response for pulsed or modulated systems.
• Low Power Consumption: 34 mA supply current balances performance with efficiency.
• Precision Gain Control: Variable gain adjustment for flexible signal amplification.
• Robust Packaging: MSL-2 rated 10-VSSOP ensures reliability in surface-mount assemblies.
