The ADG1519 is a single-pole, double throw (SPDT) switch. An EN input on the lead frame chip scale package (LFCSP) is used to enable or disable the device. When disabled, the switch terminals (SA, SB, and D) are high impedance.

The ADG1519 is fully specified at VDD = +5 V ± 10% and VSS = –4.5 V to –8.8 V for applications that require asymmetrical supplies. The ADG1519 on-resistance profile is flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals. The construction ensures ultra low power dissipation, making the device ideally suited for portable and battery-powered instruments.

The switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The ADG1519 exhibits break-before-make switching action for use in multiplexer applications.

APPLICATIONS

  • LDMOS power amplifier gate drive
  • GAN power amplifier gate drive
  • Communication systems
  • Automatic test equipment
  • Data acquisition systems
  • Sample-and-hold systems

    • VSS = –8 V
  • Parallel interface compatible with 3 V logic

Product Detail

The EVAL-ADG1519EBZ is the evaluation board for the ADG1519, which features a single channel, single-pole, double through (SPDT) switch. The ADG1519 is fully specified for asymmetrical voltage supplies of VDD = +5 V ± 10% and VSS = –4.5 V to –8.8 V.

Figure 1 in the user guide shows the EVAL-ADG1519EBZ in a typical evaluation setup. The ADG1519 is soldered to the center of the evaluation board, and two wire screw terminals are provided to connect to each of the source pins and the drain pin. Three screw terminals are used to power the device, with a fourth terminal used to provide a optional logic voltage for the digital control of the ADG1519.

Full specifications on the ADG1519 are available in the product data sheet, which should be consulted in conjunction with the user guide when using the EVAL-ADG1519EBZ.
