TMUX7219DGKRQ1 – TEXAS INSTRUMENTS

The Texas Instruments TMUX7219DGKRQ1 is a low-power, single-supply, 1:8 analog multiplexer with integrated level shifting. This device features eight individually controlled analog input channels, each capable of handling signals within a 0V to VCC range, typically 1.8V to 5.5V. The output is a single analog signal mirroring the selected input channel. It operates with a maximum supply current of 1.5mA (typical) and boasts a low ON-resistance of 15Ω (typical), minimizing signal attenuation. The device utilizes a CMOS process, resulting in low power consumption and high input impedance._x000D_

Packaged in a space-saving 10-pin WSON (WCSP) package (4mm x 3mm), the TMUX7219DGKRQ1 is ideal for applications requiring compact size and low power, such as portable instrumentation, data acquisition systems, and sensor multiplexing. Its low ON-resistance makes it suitable for high-precision analog signal routing where signal integrity is paramount. The integrated level shifting allows for seamless interfacing with different voltage domains within a system, simplifying circuit design and reducing the need for external level-shifting circuitry. The device’s excellent linearity and low distortion characteristics contribute to accurate signal reproduction. Its single-supply operation further simplifies power management requirements.
