OPA875IDGKTG4

Analog Switches - Special Purpose Overview

The OPA875IDGKTG4 is a single-channel, high-speed video multiplexer manufactured by Texas Instruments. It features a 2:1 switching architecture designed for signal routing applications. The device operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical quiescent current of 10 mA per channel. Key electrical specifications include a bandwidth of 300 MHz and a settling time of 6 ns to 0.01%. The input offset voltage is typically 1 mV, with an output swing capability that reaches within 100 mV of the rails. It supports data rates up to 200 Mbps and maintains a low on-resistance of 15 ohms. The component is housed in an 8-pin VSSOP package and functions reliably across an operating temperature range from -40°C to +85°C.

Analog Switches - Special Purpose Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm the specific tape-and-reel packaging configuration matches your automated assembly requirements. Cross-reference the datasheet revision date to ensure alignment with the latest electrical characteristics and mechanical drawings before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when a single-channel, high-bandwidth multiplexer is required for video or high-frequency analog signals. Consider the 300 MHz bandwidth and 6 ns settling time for applications demanding rapid signal transitions. Evaluate the 10 mA quiescent current against system power constraints. Ensure the VSSOP-8 package footprint fits the available PCB real estate compared to alternative pin-compatible packages.

Analog Switches - Special Purpose Part Context

This device belongs to the OPA87x family of high-speed video multiplexers from Texas Instruments. It shares architectural similarities with other members like the OPA876 but differs in channel count and specific performance metrics. The IDGKTG4 designation indicates a specific industrial temperature grade and reel packaging variant within the broader product line.

Analog Switches - Special Purpose Replacement Considerations

The OPA876IDGKTG4 serves as a related dual-channel alternative within the same family. Verify pin compatibility and electrical parameter differences such as bandwidth and current consumption before substituting. No direct cross-manufacturer equivalents are confirmed in public documentation.
