ADG1519 Datasheet | Analog Devices

FEATURES - 3.8 Ω on resistance - Specified at - VDD = +5 V ± 10% - VSS = - 4.5 V to - 8.8 V - No VL supply required - 3 V logic-patible inputs - Up to 310 m A continuous current - Rail-to-rail operation - 8-lead, 2 mm × 3 mm LFCSP APPLICATIONS - LDMOS power amplifier gate drive - GAN power amplifier gate drive - munication systems - Automatic test equipment - Data acquisition systems - Sample-and-hold systems GENERAL DESCRIPTION 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. Data Sheet ADG1519 3.8 Ω On-Resistance, SPDT Switch FUNCTIONAL BLOCK DIAGRAM Figure 1.
