AD8138ARZ, Дифференциальный драйвер АЦП с низким уровнем …The AD8138ARZ is a low distortion Differential Analogue-to-digital Converter Driver for differential signal processing. This can be used as a single-ended-to-differential amplifier or as a differential-to-differential amplifier. Manufactured on ADIs proprietary XFCB bipolar process, this has -3dB bandwidth of 320MHz and delivers a differential signal with the lowest harmonic distortion available in a differential amplifier. This has a unique internal feedback feature that provides balanced output gain and phase matching, suppressing even order harmonics. The internal feed-back circuit also minimizes any gain error that would be associated with the mismatches in the external gain setting resistors. Its differential output helps balance the input to differential ADCs, maximizing the performance of the ADC. This eliminates the need for a transformer with high performance ADCs, preserving the low frequency and DC information., Easy to use, single-ended-to-differential conversion, Adjustable output common-mode voltage, Externally adjustable gain, Fast settling to 0.01% of 16ns, Fast overdrive recovery of 4ns, 5nV/?Hz Low input voltage noise, 1mV Typical offset voltage, 90mW on 5V Low power
