VCA810A Description

Short technical summary and product information.

The VCA810A from Texas Instruments is a dc-coupled, wideband, continuously variable, voltage-controlled gain amplifier. It offers a high gain adjust range of ±40dB, with a gain control linearity of ±0.3dB and a gain control bandwidth of 25MHz. The amplifier provides a constant bandwidth of 35MHz across the gain adjust range.

 

Operating from ±5V supplies, the VCA810A features low input noise voltage of 2.4nV/√Hz and a low output DC error of less than ±40mV. It can deliver a high output current of ±60mA and has a low supply current of 24.8mA maximum. The operating temperature range is from -40°C to +85°C.

 

Applications for the VCA810A include optical receiver time gain control, sonar systems, voltage-tunable active filters, log amplifiers, pulse amplitude compensation, and AGC receivers with RSSI. Its differential input and single-ended output make it suitable for various signal processing tasks.
