MCP42100中文资料8-Bit Dual Digital POT with SPI数据手册Microchip规格书

描述 Description

The MCP42100 is a single-channel, 8-bit digital potentiometer features 100kΩ end-to-end resistance value with an SPI serial interface. The wiper position varies linearly and is controlled via the SPI interface. The MCP42100 has outstanding AC and DC characteristics, and consumes <1 µA during static operation. Applications for the MCP42100 digital potentiometer include audio equipment (volume and tone controls), servo-motor control, battery charging and control, communications (line impedance matching), power supplies, instrumentation (gain, offset adjust), LCD contrast control and programmable filters. The MCP42100 is available in 8-pin PDIP and SOIC packages.

简介

MCP42100属于集成电路（IC）的数字电位计。由制造生产的MCP42100数字电位计数字电位器是一系列集成电路器件，可提供类似于传统机械电位器或变阻器的可调节电阻，但通过电子信号而非机械输入来进行控制。虽然这些器件的电阻可耗散的电能相对有限，但其电子控制能力有助于小型化、自动化和远程控制信号级模拟电路，而这些电路本来可能会使用机械电位器。
