MP4895A

96-Channel, High-Voltage Analog Switch with Output Bleed Resistors and 5V Bias

详情

The MP4895A is a 96-channel, high-voltage analog switch with integrated output bleed resistors, designed for medical ultrasound imaging applications. It is designed to multiplex the transmission and can receive voltages to and from multiple piezoelectric transducers (PZTs).

The 96 switches are configured as 32 1:3 multiplexers and demultiplexers. The MP4895A has 32 switch inputs. Each switch input is connected to three switch outputs (SWOUTA, SWOUTB, and SWOUTC) for a total of 96 switch outputs. The MP4895A is controlled by a 96-bit serial shift registers, followed by a 96-bit data latches. The switches can be turned on/off via the 96-bit serial shift register.

The MP4895A does not require any high-voltage supplies. Only two low-voltage supplies are required (3.3V and 5V). The analog switch can block or pass analog voltages up to ±90V with peak currents of up to ±1.8A.

The MP4895A is available in a BGA-144 (10mmx10mm) package.

MP4835AGRD 集成输出泄放电阻、具有 5V 偏压的 32 通道、高压模拟开关

MP4835A 是一款集成输出泄放电阻的 32 通道、高压、单刀单掷（SPST）模拟开关，设计用于医疗超声成像应用。它专门用于对往返于多路电压式转换器（PZT）的传输电压和接收电压进行多路复用。输出开关由后跟 32 位数据锁存器的 32 位串行移位寄存器控制。它提供了数据输出（DOUT）引脚，使多个器件可以级联在一起。这将有助于最大限度减少输入/输出（I/O）控制线路的数量。数据锁存器中的逻辑高电平信号将使相应的模拟开关导通，而逻辑低电平信号使其关断。

MP4835A 无需任何高压电源。仅需两个低压电源（3.3V 和 5V）。模拟开关可阻断或传递高达 ±100V 的模拟电压，峰值电流高达 ±1.8A。

MP4835A 采用 QFN-72（10mmx10mm）封装。
