7.3.6 MUX-Friendly Inputs

The TLV2186 features a proprietary input stage design that allows an input differential voltage to be applied while maintaining high input impedance. Typically, high-voltage CMOS or bipolar-junction input amplifiers feature antiparallel diodes that protect input transistors from large VGS voltages that may exceed the semiconductor process maximum and permanently damage the device. Large VGS voltages can be forced when applying a large input step, switching between channels, or attempting to use the amplifier as a comparator.

The TLV2186 solves these problems with a switched-input technique that prevents large input bias currents when large differential voltages are applied. This solves many issues seen in switched or multiplexed applications, where large disruptions to RC filtering networks are caused by fast switching between large potentials. The TLV2186 offers outstanding settling performance as a result of these design innovations and built-in slew rate boost and wide bandwidth. The TLV2186 can also be used as a comparator. Differential and common-mode Absolute Maximum Ratings still apply relative to the power supplies.
