MAX9650AUA+

Video Amps And Modules Overview

The MAX9650AUA+ is a single-channel high-current VCOM drive operational amplifier designed for TFT-LCD applications. It operates on a supply voltage range of 6V to 20V and delivers up to 1300mA peak output current per channel. The device features rail-to-rail inputs and outputs, a 40V/μs slew rate, and a 35MHz bandwidth. 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 an 8-pin μMAX-EP package.

• Instrument Control Voltage Sources

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix matches the required package type, as the MAX9650 series is available in SOT23, μMAX-EP, and TDFN-EP configurations. Confirm that the lead-free/RoHS-compliant designation (+) aligns with environmental requirements. Ensure the design accounts for the exposed pad connection to ground for proper thermal performance and electrical grounding.

Video Amps And Modules Selection Notes

Select this component when driving large capacitive loads typical of TFT-LCD backplanes requiring rapid current sourcing and sinking. The exposed pad package is necessary for managing thermal dissipation during high peak current operation. Verify that the system power supply falls within the 6V to 20V operating range and that the layout supports the required bypass capacitance near the VDD pin.

Video Amps And Modules Part Context

This part belongs to the MAX9650/MAX9651 family of high-current VCOM drive op amps. The MAX9650 variant provides a single channel, whereas the MAX9651 offers dual channels. Both share identical electrical characteristics and are optimized for holding VCOM voltage stable in display applications. The AUA+ suffix specifically denotes the single-channel version in the 8-pin μMAX-EP package.
