Trench Isolation Guards Against Latch-Up and Minimizes metal-oxide semiconductor (CMOS) analog multiplexer designed Parasitic Leakage. for operation up to 210C. The ADG5298 switches one of eight A dielectric trench separates the P channel and N channel inputs to a common output, as determined by the 3-bit binary transistors to prevent latch-up even under severe overvoltage address lines, A0, A1, and A2. conditions. An EN input enables or disables the device. When EN is disabled, 2. Achieved JESD78D Class II rating. all channels switch off. The ultralow capacitance and charge The ADG5298 was stressed to 500 mA with a 10 ms pulse injection of this switch makes it an ideal solution for data at the maximum temperature of the device (210C). acquisition and sample-and-hold applications, where low glitch 3. 0.2 pC Charge Injection. and fast settling are required. 4. Dual-Supply Operation. The switch conducts equally well in both directions when on, For applications where the analog signal is bipolar, the and it has an input signal range that extends to the power supplies. ADG5298 can operate from dual supplies of up to 22 V. In the off condition, signal levels up to the supplies are blocked. 5. Single-Supply Operation. This multiplexer is available in a 16-lead ceramic flat package For applications where the analog signal is unipolar, the (FLATPACK) and a 16-lead ceramic flat package with reverse ADG5298 can operate from a single rail power supply of formed gullwing leads (FLATPACK RF). Both packages are up to 40 V. designed for robustness at extreme temperatures and are 6. 3 V Logic-Compatible Digital Inputs. qualified for up to 1000 hours of operation at the maximum V = 2.0 V, V = 0.8 V.
