GENERAL DESCRIPTION PRODUCT HIGHLIGHTS
The ADG5236 is a monolithic CMOS device containing two 1. Trench Isolation Guards Against Latch-Up. independently selectable single-pole/double throw (SPDT) A dielectric trench separates the P and N channel switches. An EN input on the LFCSP package enables or transistors thereby preventing latch-up even under severe disables the device. When disabled, all channels switch off. Each overvoltage conditions. switch conducts equally wel in both directions when on and 2. Ultralow Capacitance and <1 pC Charge Injection. has an input signal range that extends to the supplies. In the off 3. Dual-Supply Operation. condition, signal levels up to the supplies are blocked. Both For applications where the analog signal is bipolar, the switches exhibit break-before-make switching action for use in ADG5236 can be operated from dual supplies up to ±22 V. multiplexer applications. 4.
