CAT521集成电路（IC）的数字电位计规格书PDF中文资料

CAT521属于集成电路（IC）的数字电位计。由安森美半导体制造生产的CAT521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。

DESCRIPTION

The CAT521 is a 8-bit digitally-programmable potentiometer (DPP™) configured for programmable voltage and DAC-like applications. Intended for final calibration of products such as camcorders, fax machines and cellular telephones on automated high volume production lines, it is also well suited for self-calibrating systems and for applications where equipment which requires periodic adjustment is either difficult to access or in a hazardous environment.

FEATURES

■ 8-bit DPP configured as a programmable voltage source in DAC-like applications

■ Buffered wiper output

■ Non-volatile NVRAM memory wiper storage

■ Output voltage range includes both supply rails

■ 1 LSB accuracy, high resolution

■ Serial Microwire-like interface

■ Single supply operation: 2.7V – 5.5V

■ Setting read-back without effecting outputs

APPLICATIONS

■ Automated product calibration

■ Remote control adjustment of equipment

■ Offset, gain and zero adjustments in self-calibrating and adaptive control systems

■ Tamper-proof calibrations

■ DAC (with memory) substitute
