The ADG5298 is a latch-up proof, monolithic, complementary metal-oxide semiconductor (CMOS) analog multiplexer designed 1. Trench Isolation Guards Against Latch-Up and Minimizes for operation up to 210°C. The ADG5298 switches one of eight Parasitic Leakage. inputs to a common output, as determined by the 3-bit binary A dielectric trench separates the P channel and N channel address lines, A0, A1, and A2. transistors to prevent latch-up even under severe overvoltage An EN input enables or disables the device. When EN is disabled, conditions. all channels switch off. The ultralow capacitance and charge 2. Achieved JESD78D Class II rating. injection of this switch makes it an ideal solution for data The ADG5298 was stressed to ±500 mA with a 10 ms pulse acquisition and sample-and-hold applications, where low glitch at the maximum temperature of the device (210°C). and fast settling are required. 3. 0.2 pC Charge Injection. 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 VINH = 2.0 V, VINL = 0.8 V. temperature rating. 7. No Logic Power Supply (VL) Required. The ADG5298 is a member of a growing series of high temperature qualified products offered by Analog Devices, Inc.
