In Electronic Infomation Category: R | on November 1, 2010
Analog Devices (ADI) introduced the new Precision Amplifier - AD8655, for less than 5V, 5V, and SN74LVC08ADR datasheet and the work conditions and SN74LVC08ADR price and requirements of low noise instrumentation, audio, communications and SN74LVC08ADR suppliers and medical applications. According to reports, AD8655 is the industrys first 2.7V to 5V operating in the lowest noise precision amplifier. Its price significantly lower than the bipolar solutions.
This section amplifier 10kHz, with the lowest 2.7nV/rtHz noise, low distortion of 0.0008%, omitted to reduce system-level external noise amplifier transistor-level or more parallel, but also to improve the signal to noise ratio and resolution.
In the entire common-mode voltage range, 250uV low DC offset with high accuracy without the need to adjust the system. AD8655 amplifier rail to rail input and output makes it very suitable for use in high-precision drive system ADC, as well as the DAC to provide caching.
ADI plans to release this years dual and quad amplifier versions. AD8655 work in -40 ℃ to 125 ℃, a bandwidth of 28MHz, offset voltage drift is typically 0.4uV / ℃, maximum 2.3uV / ℃.
AD8655 8-pin MSOP and SOIC two packages, when the set capacity of 1,000, is priced at $ 0.70.
