MAX9503METE+

Video Amps And Modules Overview

The MAX9503METE+ is a DirectDrive video amplifier with an integrated reconstruction filter, manufactured by Analog Devices Inc. (formerly Maxim Integrated). It operates from a single 2.7V to 3.6V supply and features a preset voltage gain of 12dB. The device utilizes internal charge pump and linear regulator technology to generate a negative supply rail, enabling DC-coupled output with the black level set to ground. It includes a six-pole Butterworth lowpass filter for signal smoothing and offers a low-power shutdown mode consuming less than 10nA. The component is specified over an extended temperature range of -40°C to +85°C.

Video Amps And Modules Feature Summary

• DirectDrive technology eliminates large output-coupling capacitors by generating an internal negative supply
• Integrated six-pole Butterworth reconstruction filter smooths DAC output steps and reduces spikes
• Video output black level is fixed at ground potential for direct connection to downstream circuitry
• Ultra-low power shutdown mode reduces quiescent current to below 10nA

Video Amps And Modules Applications

• Digital still cameras
• Mobile phones and smartphones
• Security cameras
• Portable media players
• Space-constrained, low-power portable devices

Video Amps And Modules Procurement Notes

Verify that the ordering suffix 'ETE' corresponds to the 16-pin TQFN package configuration as documented in the official datasheet. Confirm the specific gain variant matches project requirements, as this part number denotes the 12dB gain version. Ensure compatibility with the required 2.7V to 3.6V single-supply voltage rails and verify that the -40°C to +85°C operating temperature range meets environmental specifications.

Video Amps And Modules Selection Notes

Select this component when space constraints prohibit the use of large external coupling capacitors typically required for AC-coupled video outputs. It is suitable for applications requiring direct interfacing with video digital-to-analog converters without additional level-shifting components. Consider the 12dB gain setting for signal amplification needs and utilize the shutdown pin for battery-powered systems requiring minimal standby current consumption.

Video Amps And Modules Part Context

This device belongs to the MAX9503 family of DirectDrive video amplifiers. The family includes variants with different gain settings, such as the MAX9503G which provides 6dB gain. All variants share the same core architecture, including the integrated charge pump, linear regulator, and reconstruction filter. The METE suffix specifically identifies the 12dB gain version packaged in a 16-lead Thin Quad Flatpack No-Lead (TQFN) format.
