Norwood, MA (10/04/2006) -
About the AD5522
Analog Devices is introducing the industry’s first quad-channel PMU (parametric measurement unit). The AD5522 combines four independent channels in a space-saving 12 mm × 12 mm TQFP package. Each of the four channels includes on-chip sense resistors for 5 microamp, 20 microamp, 200 microamp and 2 milliamp current ranges. In addition, an external range is available on each channel, enabling designers to generate up to 64 milliamps with an external sense resistor—or higher currents with an external buffer. The device features a 22.5 V voltage span that is both scalable and offsetable, providing greater design flexibility. Twenty 16-bit DACs (digital-to-analog converters) are provided on-chip for setting force, clamp and comparator levels.
This PMU has no performance tradeoffs, enabling designers to force voltage and measure current precisely, while reducing design time and minimizing board space requirements. Overall, the AD5522 offers a level of performance and integration unattainable in existing solutions from both ADI and its competitors.
Each channel includes voltage and current clamps, a window-comparator and a guard amplifier. A full set of registers is included for each mode of operation, making it easier to perform system calibration. All PMU functions are controlled via a serial SPI or LVDS interface. The 80-lead TQFP package is available with the paddle on either top- or bottom-side, giving designers a choice as to how to cool the part.
The AD5522’s channel integration, compact size, 22.5 V output range and high accuracy make it an ideal solution for ATE and instrumentation applications, such as memory testers, SOC testers, voltage/current sources and analog instruments with high precision source and measurement circuitry.
Pricing and Availability
The AD5522 is sampling now in an 80-lead, 12 mm × 12 mm TQFP package and is scheduled for release in April 2007. The AD5523, a related product without the LVDS interface and external current range, is available in a smaller 64-lead, 9 mm × 9 mm LFCSP package. Pricing for 1,000-piece quantities is $39.00 per unit for the AD5522 and $31.00 for the AD5523. An evaluation board is available for the AD5522.
