AD7706BR: 3V或5V、1mW、3通道伪差分、16位Σ-Δ ADC

AD7705AD7706均为完全16位、低成本Σ-Δ ADC,适合直流测量和低频交流测量应用,其具有低功耗(3 V时最大值为1 mW )特性,因而可用于环路供电、电池供电或本地供电的应用中。片内可编程增益放大器提供从1至128的增益设置,无需使用外部信号调节硬件便可接受低电平和高电平模拟输入。

AD7705拥有两个差分通道,而AD7706则拥有一个差分通道和两个伪差分通道。在定制比率应用器件时,差分基准电压输入还能提供极大的灵活性。

The AD7705 and AD7706 are complete 16-bit, low-cost, Sigma Delta ADCs intended for dc and low-frequency ac measurement applications. Their low power (1 mW max @ 3 V) allows them to be used in loop-powered, battery-powered or locally-powered applications. The on-chip Programmable Gain Amplifier with gain settings from I through 128 can accommodate both low-level and high-level analog inputs with no external signal conditioning hardware.

The AD7705 has two differential channels while the AD7706 has one differential and two pseudo-differential channels. Differential reference inputs also allow maximum flexibility in tailoring the device for use in ratiometric applications.
