MAX9650ATA+

Video Amps And Modules Overview

The MAX9650ATA+ is a single-channel VCOM amplifier with rail-to-rail inputs and outputs. It operates on a supply voltage range of 6V to 20V, drawing a typical quiescent current of 3.7mA per channel. The device delivers a transient peak output current of ±1.3A and features a 40V/μs slew rate with a 35MHz bandwidth. Input offset voltage is typically ±3.5mV at +25°C, expanding to ±17mV across the -40°C to +125°C temperature range. It includes thermal shutdown protection triggered at +170°C with 15°C hysteresis.

Video Amps And Modules Procurement Notes

Verify the specific suffix 'ATA+' corresponds to the TDFN-EP package configuration before procurement. Confirm that the component meets RoHS compliance requirements as indicated by the '+' designation. Ensure the ordering documentation explicitly references the Analog Devices / Maxim Integrated manufacturer source to guarantee authenticity and traceability.

Video Amps And Modules Selection Notes

Select this component when high transient current sourcing and sinking are required for capacitive loads like LCD backplanes. The exposed pad package facilitates efficient heat dissipation during high-current operations. Verify that the 35MHz bandwidth and 40V/μs slew rate meet the settling time requirements for the target display frame rates.

Video Amps And Modules Part Context

The MAX9650ATA+ belongs to the MAX9650/MAX9651 family of high-current VCOM drive operational amplifiers designed specifically for TFT-LCD applications. This series provides robust performance for stabilizing common-mode voltages in display panels.
