其它特性包括：集成缓冲用来驱动基准电压，以及集成完全差动放大器用来缓冲调制器输入并进行电平转换。

Other features include an integrated buffer to drive the reference as well as a fully differential amplifier to buffer and level shift the input to the modulator.

这种采用锁相技术、同步检波的原理，降低了整个系统的成本，提高了灵敏度，并使得载波信号与调制信号完全达到同步。

The application of phase-locked and synchronous detection reduce the cost of the whole system and improve the sensitivity. Carrier signal and modulation signal achieve entirely synchronous too.
