MAX9586MAX9589 19-0744 Rev 6 2/11 Single, Dual, Triple, and Quad Standard-Definition Video Filter Amplifiers with AC-Coupled Input Buffers General Description Features Single- (MAX9586), Dual- (MAX9587), The MAX9586MAX9589 are small, low-power, multi- Triple- (MAX9588), and Quad- (MAX9589) channel video amplifiers with integrated reconstruction Channel Devices filters and input clamps. Specially suited for standard- definition video signals, these devices are ideal for a 8.5MHz, 1dB Passband wide range of television and set-top box applications. 55dB Attenuation at 27MHz The video signals from the outputs of a digital-to-analog Fixed Gain of 2V/V converter (DAC) are AC-coupled to the inputs of the Low Power: 4.25mA per Channel MAX9586MAX9589. External video signals, in which 2.7V to 3.6V Single-Supply Operation the DC bias is usually not known, can also be AC-cou- pled to the inputs of the MAX9586MAX9589. The input Small SOT23 and MAX Packages sync-tip clamps set the DC level of composite video or luma signals, and the input bias circuits set the DC level of chroma signals. Ordering Information The reconstruction filter typically has 1dB passband PART PIN-PACKAGE CHANNELS flatness at 8.5MHz and 55dB attenuation at 27MHz. The 5 Thin SOT23 MAX9586AZK+T 1 amplifiers have 2V/V gain and the outputs can be DC- MAX9587AZT+T 6 Thin SOT23 2 coupled to a 75 load, which is the equivalent of two video loads, or AC-coupled to a 150 load. 8 MAX MAX9588AUA+T 3 The MAX9586MAX9589 operate from a 2.7V to 3.6V sin- 10 MAX MAX9589AUB+T 4 gle supply and are specified over the -40C to +125C Note: All devices are specified over the -40C to +125C operat- automotive temperature range.
