MCP41HV51数据手册集成电路（IC）的数字电位计规格书PDF

描述 Description

MCP41HV51 is a single-channel, high voltage digital potentiometer (Digipot) family that supports 10V ~36V or +/-5V to +/-18V power rails. It features 8-bit resolution with SPI interface. This family is available in TSSOP-14 and QFN-20 (5x5) packages and has 5kΩ, 10 kΩ, 50 kΩ, and 100 kΩ end-to-end resistance(RAB) options . All parts are guaranteed to operate over  –40°C to +125°C extended temperature range.Microchip's MCP41HVX1 and MCP45HVX1 digital potentiometer (Digipot) families offer the widest operating voltage range that is currently available on the market.

简介

MCP41HV51属于集成电路（IC）的数字电位计。由制造生产的MCP41HV51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。
