MAX9650AZK+T

Video Amps And Modules Overview

The MAX9650AZK+T is a single-channel VCOM amplifier with rail-to-rail inputs and outputs. It operates on a supply voltage range of 6V to 20V, delivering up to 1300mA peak output current per channel. The device features a 40V/μs slew rate and a 35MHz bandwidth for fast settling in high frame rate displays. Quiescent current is typically 5mA per channel. It includes output short-circuit protection and thermal shutdown at +170°C with 15°C hysteresis. The component is housed in a 5-pin SOT23 package.

• Rail-to-rail input and output operation ensures maximum dynamic range across the full supply voltage spectrum
• Integrated thermal shutdown with temperature hysteresis protects the device from overheating during high-power operation

Video Amps And Modules Applications

• TFT-LCD panel backplane driving
• Instrument control voltage sources

Video Amps And Modules Procurement Notes

Verify the specific suffix AZK corresponds to the SOT23-5 package configuration before procurement. Confirm that the lead-free/RoHS-compliant status (+) aligns with environmental requirements. Ensure the operating temperature range of -40°C to +125°C meets the target application's thermal constraints. Cross-reference the pinout diagram with the PCB footprint design to guarantee correct orientation and exposed pad connectivity if applicable.

Video Amps And Modules Selection Notes

Select this component when driving large capacitive loads typical of TFT-LCD backplanes requiring rapid current transients. The 35MHz bandwidth and 40V/μs slew rate are suitable for Full HD television applications operating at 120Hz frame rates. Consider the SOT23 package thermal limitations; ensure adequate board layout or lower duty cycles to prevent triggering the internal thermal shutdown mechanism under continuous heavy load conditions.

Video Amps And Modules Part Context
