1.8V video amplifiers hit a new low in power consumption

Sunnyvale, Calif.—Maxim Integrated Products has developed a pair of 1.8-V video amplifiers, the MAX9509 and MAX9510, that consume approximately 70% less average power than existing products.

By using a digital 1.8-V power supply to power the analog video amps, customers can potentially eliminate the analog supply and save both space and cost, the company said.

According to Maxim, the MAX9509 and MAX9510 push the power-consumption limit to a new low by operating the video amps at 1.8-V. The devices leverage the company's DirectDrive technology to generate a clean, internal negative supply. By combining the internal negative power supply with the external positive 1.8V supply, the MAX9509 and MAX9510 drive a 2Vp-p video signal into a 150 ohm load.

Operating at the 1.8V single power supply, the amplifiers use 70% less power; they consume 5.8mW quiescent power and 11mW average power. If customers use the 1.8V digital supply, they can eliminate the analog supply, simplifying designs and saving both space and cost.

Offered in a 2mm x 2mm TDFN, the amplifiers target portable applications such as digital still cameras (DSC), digital camcorders (DVC), and mobile phones.

The MAX9509 are MAX9510 are offered in the -40 degrees Celsius to +125 degrees Celsius automotive temperature range.

Pricing: The MAX9509 and MAX9510 are priced at $0.49 and $0.45, respectively (1000-up, FOB USA).
Availability: The MAX9509 is available in an 8-pin TDFN and the MAX9510 in an 8-pin microMAX. Samples and evaluation (EV) kits are available.
