TLV74111PDQNR

The Texas Instruments TLV74111PDQNR is a high-performance, low-power, single-supply, 8-input, analog multiplexer (MUX). It is designed to select one of eight differential input signals to be presented at a single-ended output. The device is available in a small, thermally enhanced, 16-pin QFN package, making it suitable for a wide range of applications.

Description:

The TLV74111PDQNR is a member of the TLV7411x family of analog multiplexers, which offer low on-resistance, low input offset voltage, and low input bias current. The device features Rail-to-Rail input and output, which allows it to operate with input signals that can swing from the negative supply rail to the positive supply rail.

Features:

1. Single-supply operation: The TLV74111PDQNR operates from a single supply voltage ranging from 2.7V to 5.5V.
2. 8-input, single-ended output: The device can select one of eight differential input signals to be presented at a single-ended output.
3. Low on-resistance: The on-resistance of the TLV74111PDQNR is typically 3.5 ohms, which helps minimize signal degradation.
4. Low input offset voltage: The input offset voltage is typically 1mV, ensuring accurate signal selection.
5. Low input bias current: The input bias current is typically 1pA, which minimizes the loading effect on the input signal sources.
6. Rail-to-Rail input and output: The device can handle input signals that can swing from the negative supply rail to the positive supply rail.
7. Small package: The TLV74111PDQNR is available in a 16-pin QFN package, making it suitable for space-constrained applications.
