... GENERAL DESCRIPTION The AD8517 brings precision and bandwidth to the SOT-23-5 package even at single supply voltages as low as 1.8 V. The small package makes it possible to place the AD8517 next to sensors, reducing external noise pickup. The AD8527 dual amplifier is offered in the space-saving MSOP package. The AD8517 and AD8527 are rail-to-rail input and output bipolar amplifiers with a gain bandwidth of 7 MHz and typical voltage offset of 1 ...

... AD8517 performance, which is a critical feature with a rail-to-rail amplifier model. The model also accu- rately simulates many ac effects, such as gain-bandwidth product, phase margin, input voltage noise, CMRR and PSRR versus frequency, and transient response. Its high degree of model accuracy makes the AD8517 macro-model one of the most reliable and true-to-life models available for any amplifier ...
