Product introduction

LTC1662MSOP 封装的超低功率、双通道 1

peculiarity

超低功率：每个 DAC 的 I_CC为 1.5μA (典型值)，睡眠模式的消耗电流为 0.05μA，可延长电池的使用寿命
纤巧：两个采用 8 引脚 MSOP 封装的 10 位 DAC —— 尺寸为 SO-8 封装的一半
2.7V 至 5.5V 的宽电源范围
用于同时 DAC 更新的双缓冲
轨至轨电压输出可驱动 1000pF 的容性负载
基准范围包括电源以提供比例式 0V 至 V_CCoutput
基准输入阻抗与代码无关 (典型值为 7.1MΩ )—— 免除了外部缓冲器
具施密特 (Schmitt) 触发器输入的三线式串行接口
差分非线性度：±0.75LSB (最大值)

description

LTC^®1662 是一款超低功率、全缓冲电压输出、双通道 10 位数模转换器 (DAC)。每个 DAC 通道仅吸收 1.7μA (典型值) 的总电源 + 基准工作电流，然而却能够提供超过 1mA 的 DC 输出电流，并可靠地驱动高达 1000pF 的容性负载。一种可编程睡眠模式进一步把总工作电流减小至 0.05μA。

凌力尔特公司专有的本质单调架构提供了超卓的线性度，并实现了异常小巧的外部形状。双缓冲输入逻辑电路提供了同时更新能力，并可用于执行至 DAC 的写操作，而不会中断睡眠模式。

凭借其微小的工作电流和异常纤巧的外形尺寸，LTC1662 非常适用于大多数功率受限的产品。对于大部分设计而言，它对功率预算没有明显的影响；LTC1662 的吸收电流甚至比一个可变电阻还要低好多倍，同时提供了缓冲的低阻抗 (典型值为 0.5Ω，V_CC= 5V) 轨至轨输出。

LTC1662 与 LTC1661 双通道、60μA、10 位 DAC 是引脚和软件兼容的。该器件采用 8 引脚 MSOP 封装和 PDIP 封装，并具有规定的工业温度范围。
