概述

  • ±1.08V 至 ±2.75V 双电源
  • +1.08V 至 +5.5V 单电源
  • 低导通电阻 2.4Ω
  • 16 引脚，2mm × 2mm LGA
  • 1.8 V 和 3 V JEDEC 兼容逻辑
  • 完全额定电压为±5V、+3.3V、+1.8V 和±2.5V
  • 轨到轨信号范围
  • 工作温度范围：−40 °C 至 +125 °C

ADG1712 包含四个独立的单刀单掷 (SPST) 开关，采用 +1.08V 至 + 5.5V 的低压单电源范围或 ±1.08V 至 ±2.75V 的低压双电源范围工作。

ADG1712 设计尺寸小巧，但不影响性能。2mm × 2mm 平面网格阵列封装 (LGA) 封装非常适合需要考虑面积的各种应用。

ADG1712 具有仅为 2.4Ω 的低导通电阻和轨到轨输入信号范围。每个开关在打开时在两个方向上的导电性能都一样好。开关通过相应数字控制线上的逻辑 1 输入打开，数字控制输入符合 1.8V 和 3V JEDEC 标准，可轻松与微控制器和现场可编程门阵列 (FPGA) 一起使用。

应用

  • 自动测试设备
  • 数据采集系统
  • 医疗器械
  • FPGA 和微控制器系统
  • 音频和视频信号路由
  • 通信系统
  • 继电器替代方案

产品详情

The EVAL-ADG1712ARDZ is the evaluation board for the ADG1712. The ADG1712 contains four independent SPST switches. The ADG1712 operates with a low voltage single supply range from +1.08V to + 5.5V, or a low voltage dual supply range from ±1.08V to ±2.75V.

The ADG1712 is designed for small size without compromising on performance. The 2mm × 2mm LGA package is ideal for a broad range of applications where area is a concern.

The ADG1712 has a low on resistance of just 2.4Ω and a rail-to-rail input signal range. Each switch conducts equally well in both directions when on. The switches are turned on with a Logic 1 input on the corresponding digital control line and the digital control inputs are 1.8V JEDEC compliant for ease of use with microcontrollers and field programmable gate arrays (FPGAs).

Figure 1 in the User Guide shows the EVAL-ADG1712ARDZ evaluation board. The ADG1712 is located in the center of the evaluation board. Wire screw terminals are provided to connect to each of the source and drain pins as well as optional Subminiature Version A (SMA) connectors. There are multiple power options on the board for providing power supplies to the evaluation board. A four terminal screw connector can be used to provide VDD, VSS, GND, and VL connections directly to the ADG1712 from an external power supply. Alternatively on board 3.3V and 1.8V voltage regulators have been supplied to provide options for VDD and VL. The on-board voltage regulators can be powered from one of three options, the external 5V supply via the screw terminal, from the 5V USB Type-C connector on the evaluation board or using an available 5V supply from a connected SDP-K1 or compatible Arduino board.

Full specifications on the ADG1712 are available in the ADG1712 data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the EVAL-ADG1712ARDZ evaluation board.
