求职应注意的礼仪 求职时最礼貌的修饰是淡妆 面试时最关键的神情是郑重 无论站还是坐，不能摇动和抖动 对话时目光不能游弋不定 要控制小动作 不要为掩饰紧张情绪而散淡 最优雅的礼仪修养是体现自然 以一种修养面对两种结果 必须首先学会面对的一种结果----被拒绝 仍然感谢这次机会，因为被拒绝是面试后的两种结果之一。 被拒绝是招聘单位对我们综合考虑的结果，因为我们最关心的是自己什么地方与用人要求不一致，而不仅仅是面试中的表现。 不要欺骗自己，说“我本来就不想去”等等。 认真考虑是否有必要再做努力。 必须学会欣然面对的一种结果----被接纳 以具体的形式感谢招聘单位的接纳，如邮件、短信 考虑怎样使自己的知识能力更适应工作需要 把走进工作岗位当作职业生涯的重要的第一步，认真思考如何为以后的发展开好头。 Thank you * * Analog side – 6-Key features: Flexible input MUX – new to our Sigma delta devices standalone or integrated Mention input range of MUX and PGA. Input range 0-3.6V. Supply-250mV if input buffer enabled. Negative input buffer may be by-passed for Grounded inputs. Step Detection filter – Connected to Interrupt source (New) Sinc2 filter for faster less accurate output. Excitation Current sources Finer step sizes than ADuC7060 Lower drift spec if external reference resistor is used.(100ppm) Selectable External Reference input buffer for high impedance reference sources (ADS1248) Bias Voltage Generator for Thermocouple type applications: Outputs AVdd/2 supply voltage for setting common mode voltage of for example a Thermocouple. 12-Bit VDAC – DAC NPN mode configures output buffer as an OP-AMP and used to control an external FET for 4-20mA loop applications. Also… Digital LDOs Flash size DMA controller Communications Peripherals…. * ARM7 based ADuC7060 deemed too tight for most 4-20mA application. 1.25 Dhrystone MIPS v 0.7 Dhrystone MIPS on ARM7 – Aude more details. Customer wanted ADC specs to match AD7794 with higher sampling rate of 2kHz. Extra features to compete with ADC1248. * * * RF02 to release next month Move to RF101. 2 die, single chip solution. RF= ADF7023 ISM transceiver – Aude more details. Move to ADuCM360. Dual Sigma Delta ADC plus Cortex core – more details to follow. Move to ADuCM301. Bottom die of ADuCRF101. 12-Bit SAR, 1MSPS ADC – Aude to provide more details. Mention M330 development * * * * ADI has introduced a fully integrated SoC device that integrates all of the RF tran
