Description Etek Microelectronics ET7207 7 段图形均衡器 概述 这是一款采用 CMOS 技术制造的 7 段图形均衡器。它将音频频谱划分为 7 段:63Hz,160Hz,400Hz, 1kHz,2.5kHz,6.25kHz,和 16kHz。这 7 种频率的信号经过峰值检测和多路开关选择器,产生一个直流 电平输出来表示信号的振幅。不要外部元件来选择滤波器的响应。只需要一个电阻和一个电容来产生系统 时钟频率。滤波器的中心频率由这个频率所决定。另外还需要一些耦合和去耦电容。 电路可以工作在 2.7V 和 5.5V 之间,最佳工作电压为 5V。电路有着非常低的静态电流(典型值小于 ...

2- to 1-port analog switches
The ET7222 is 2­ to 1­port analog switches. Their wide bandwidth and low bit­to­bit skew allow them to pass high­speed differential signals with good signal integrity. Each switch is bidirectional and offers little or no attenuation of the high­ speed signals at the outputs. Industry­leading advantages include a propagation delay of less than 250 ps, resulting from its low channel resistance and low I/O capacitance. Their high channel­to­channel crosstalk rejection results in minimal noise interference. Their bandwidth is wide enough to pass High­Speed USB 2.0 differential signals (480 Mb/s). Features RON is Typically 6.0Ω at VCC = 3.3 V Low Bit­to­Bit Skew: Typically 50 ps Low Crosstalk: ­4...

ETIC
QUAD DIFFERENTIAL LINE DRIVER
These line drivers are pin compatible with 26LS31 in applications where pin 4 = 5V and pin 12 = GND. Internal clamp diodes allow trouble-free operation when driving cable lengths exceeding 100m. Split supplies are provided to minimize standby power dissipation in high voltage applications. The logic should be powered from a regulated 5V supply at the VccBias pin. The output stages may then be powered by a separate supply at VccDrivers, up to 30V. Output voltage swings of 0.3V to VCC-1.9V are typical. The outputs are protected against shorts to ground, shorts to Vcc and to other outputs, by a two-fold scheme of current limiting and thermal shutdown. This assures highly reliable operation in h...

QUAD DIFFERENTIAL LINE DRIVER IC
These line drivers are similar in function to the ET7272, only in an open-collector format. The VCC pin powers the internal logic only. Output voltage is dependent on the customer supplied voltage, up to a maximum of 30V. There is essentially no difference in output swing or performance with VCC (LOGIC) values from 3.5V-30V. Internal clamp diodes allow trouble-free operation when driving cable lengths exceeding 100 meters. The outputs are protected by initiating shutdown when junciton temperatures...
