Maxim Introduces the MAX9670 and MAX9671, +3.3V Dual SCART Solutions with Audio Volume Control
The MAX9670 and MAX9671 are +3.3V dual SCART solutions with audio volume control for set-top boxes and A/V receivers that have two SCART connectors. These devices utilize power-saving technologies to achieve the industry’s lowest power consumption. At 49mm² or smaller, the MAX9670/MAX9671 are the industry’s smallest complete dual SCART solutions. Though competing dual SCART devices require +5V and +12V supplies, the MAX9670 and MAX9671 operate audio and video circuitry from +3.3V and only require +12V for the slow-switching signal. An internal charge pump inverts the +3.3V supply and generates a -3.3V supply, thereby providing sufficient voltage swing to support 2.0VRMS audio. These SCART ICs integrate load-detect and activity-detect circuitry that enables designers to intelligently reduce system power consumption for extended power savings. The MAX9670 is available in a compact, 6mm x 6mm, 40-pin TQFN package, while the MAX9671 is packaged in a 7mm x 7mm, 44-pin TQFN. Both devices are fully specified over the 0°C to +70°C commercial temperature range…
