Shenzhen Mingjiada Electronics Co., Ltd. as a professional distributor in the electronic components field, maintains a long-term inventory of genuine Texas Instruments (TI) products. We now supply TI's DEM-VCA-SO-1B evaluation board (14-SOIC package, single-channel variable gain amplifier).
Product Overview Of DEM-VCA-SO-1B
The Texas Instruments (TI) DEM-VCA-SO-1B general-purpose evaluation board provides a rapid prototyping and performance testing platform for single-channel variable gain amplifiers (VCAs) in 14-pin SOIC packages. Featuring a standard SOIC-14 interface, this board flexibly accommodates multiple TI classic VCA chips, helping engineers accelerate development cycles in applications such as automatic gain control (AGC), signal conditioning, and dynamic range compression.
Specifications
Product Model: DEM-VCA-SO-1B
Package Type: 14-SOIC
Number of Channels: 1 channel (single-channel)
