MAX5403 - 双路、256抽头、低漂移、数字电位器，10引脚µMAX封装 - 光电产品 - 业内尺寸最小的双通道数字电位器 - 美信半导体
The MAX5403/MAX5404/MAX5405 is a family of duallinear taper digital potentiometers. Each device has one3-terminal potentiometer and one 2-terminal variableresistor (Figure 1). The MAX5403/MAX5404/MAX5405operate from +2.7V to +5.5V single-supply voltagesand use an ultra-low supply current of 0.1µA. Thesedevices also provide glitchless switching betweenresistors taps as well as a convenient power-on reset(POR) that sets the wiper to the midscale position atpower-up. The potentiometer consists of a fixed resistorwith a wiper contact that is digitally controlled through a3-wire serial interface and has 256-tap points. It performsthe same function as a discrete potentiometer orvariable resistor.
These parts are ideal for applications requiring digitallycontrolled resistors. Three resistance values are available:10kΩ (MAX5403), 50kΩ (MAX5404), and 100kΩ(MAX5405). A nominal resistor-temperature coefficientof 35ppm/°C end-to-end and 5ppm/°C ratiometric makethe MAX5403/MAX5404/MAX5405 ideal for applicationsrequiring low temperature-coefficient variable resistors,such as adjustable-gain circuit configurations.
The MAX5403/MAX5404/MAX5405 are available in a 10-pin µMAX® package. Each device is guaranteed over theextended industrial temperature range (-40°C to +85°C).
