Texas InstrumentsVCA2615EVM증폭기 IC 개발 보드 및 키트

The VCA2615 is a dual-channel, variable gain amplifier, combining a low-noise preamplifier (LNP) and a voltage-controlled amplifier. The VCA2615EVM evaluation module is designed to allow for a quick setup and ease of use in evaluating the performance. Various modes of operation can be configured, for example setting the LNP gain, or using the LNP outputs. The user can apply the input signal either to the LNP, or directly to the VCA section. The differential outputs of the VCA2615 are buffered using an op amp in a difference amplifier configuration.
