Микросхема AD8137YRZ, Драйвер АЦП [uMAX-8]

Характеристики

AD8137YRZ, Драйвер АЦП [uMAX-8]The AD8137YRZ is a Low Power Differential ADC Driver with a rail-to-rail output that is ideal for driving ADCs in systems that are sensitive to power. It is easy to apply and its internal common-mode feedback architecture allows its output common-mode voltage to be controlled by the voltage applied to one pin. The internal feedback loop also provides inherently balanced outputs as well as suppression of even-order harmonic distortion products. Fully differential and single-ended-to-differential gain configurations are easily realized by the AD8137. External feedback networks consisting of four resistors determine the closed-loop gain of the amplifier. The power-down feature is beneficial in critical low power applications. This ADC driver is manufactured on proprietary second-generation XFCB process, enabling it to achieve high levels of performance with very low power consumption.
