PRODUCTION DATA
汽车级 10 位 DAC53701-Q1 和 8 位 DAC43701-Q1 (DACx3701-Q1) 是具有引脚兼容性的缓冲电压输出智能数模转换器 (DAC) 系列产品。这些器件功耗极低且均可采用微型 8 引脚 WSON 封装。凭借全套功能、微型封装和低功耗,DACx3701-Q1 非常适合用于汽车应用,如改变汽车尾灯、制动灯、车牌灯的淡入淡出效果和扩展 PWM 用于车内照明等。
这些器件具有非易失性存储器 (NVM)、一个内部基准、一个兼容 PMBus 的 I2C 接口和一个通用输入。DACx3701-Q1 使用内部基准或以电源作为基准运行,并提供 1.8 V 至 5.5 V 的满量程输出。
DACx3701-Q1 是智能 DAC 器件,因为它们具有高级集成特性。凭借强制检测输出、基于 GPI 的功能触发、PWM 输出和 NVM 功能,智能 DAC 无需使用软件即可实现系统性能和控制。
