	Title:	New Quad, 12-Bit, 170 MSPS/210 MSPS/250 MSPS ADCs From Analog Devices ( 1250)
	Summary	The AD9239 is a quad, 12-bit, 250 MSPS analog-to-digital converter (ADC) with an on-chip temperature sensor and a high speed serial interface
	Main Text	Analog Devices has introduced a pair of four-channel 12-bit analog-to-digital converters (ADCs) that use 50 percent less printed-circuit-board surface area than other ADCs in their class. The AD9239 and AD9639 quad analog-to-digital converters require only eight pins and traces, compared to as many as 26 in competing dual-channel devices, which yields space savings in high-speed signal processing applications, including cable infrastructure and point-to-point wireless communications equipment and spectrum analyzers. As part of a complete receive-path signal chain solution, the AD9239 and AD9639 quad ADCs are compatible with ADI’s variable gain amplifiers, including the AD8372 and AD8376.
