ADG1519
3.8 Ω On-Resistance, SPDT Switch
FEATURES FUNCTIONAL BLOCK DIAGRAM
► 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-compatible inputs ► Up to 310 mA continuous current ► Rail-to-rail operation ► 8-lead, 2 mm × 3 mm LFCSP
APPLICATIONS
► LDMOS power amplifier gate drive
Figure 1.
► GAN power amplifier gate drive
PRODUCT HIGHLIGHTS
► Communication systems ► Automatic test equipment
1.
5.2 Ω maximum on resistance at 25°C. ► Data acquisition systems
2.
–135 dB THD. ► Sample-and-hold systems
3.
3 V logic-compatible digital inputs: VINH = 2.0 V minimum and V
GENERAL DESCRIPTION
INL = 0.8 V maximum.
4.
No logic power supply voltage (VL) required. The ADG1519 is a single-pole, double throw (SPDT) switch. An EN

8-lead, 2 mm × 3 mm LFCSP (see the Outline Dimensions input on the lead frame chip scale package (LFCSP) is used to section). 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.
