Analog Devices' Non-Volatile Digital Potentiometers Deliver Industry's Highest Bandwidth And Lowest Resistance Tolerance00:01 EST Tuesday, November 06, 2012 NORWOOD, Mass. (Business Wire) -- Analog Devices, Inc. (ADI) today introduced a series of non-volatile single-, dual- and quad-channel digital potentiometers (digiPOTs) thatimprove component matching in industrial and communication control systems by featuring resistance tolerance of ± 1 percent (typ). The 11 new digiPOTs in ADI's AD514x and AD512x series also achieve a 3-MHz bandwidth that is 50 percent higher than the closest competitor, which enables faster system response time. The new devices offer the industry's lowest temperature coefficient performance over the widest temperature range (-40°C to 125°C). ADI's non-volatile digiPOT series meets a wide range of system-level requirements in single, dual, or quad, 256-tap or 128-tap, SPI or I²C interfaces, leaded and leadless packaging, all featuring 4 kV ESD protection Download data sheets, view product pages and request samples Watch a video explaining how the problem of amplifier gain linearization can be solved by this digiPOT series Find application notes and technical articles about digital potentiometer solutions from ADI: AD514x and AD512x digiPOTS Key Features: Resistor tolerance: ±1 percent typical for better matching Wide bandwidth: 3 MHz for faster system response 3-mm x 3-mm LFCSP package option for board savings Low temperature coefficient: 35 ppm/°C over an extended temperature range Pricing, Availability and Complementary ProductsProduct       SampleAvailability         Channel       Tap       Interface       Price Each In1,000Quantities       Packaging AD5144       Yes       Quad       256       SPI/I²C       $2.90       24-lead LFCSP/20-lead TSSOP AD5144A       Yes       Quad       256       I²C       $2.90       20-lead TSSOP AD5124       Yes       Quad       128       SPI/I²C       $2.50       24-lead LFCSP/20-lead TSSOP AD5143       Yes       Quad       256       I²C       $2.85       16-lead LFCSP AD5123       Yes       Quad       128       I²C       $2.45       16-lead LFCSP AD5142       Yes       Dual       256       SPI       $1.65       16-lead LFCSP/16-lead TSSOP AD5142A       Yes       Dual       256       I²C       $1.65       16-lead LFCSP/16-lead TSSOP AD5122       Yes       Dual       128       SPI       $1.45       16-lead LFCSP/16-lead TSSOP AD5122A       Yes       Dual       128       I²C       $1.45       16-lead LFCSP/16-lead TSSOP AD5141       Yes       Single       256       SPI/I²C       $0.90       16-lead LFCSP AD5121       Yes       Single       128       SPI/I²C       $0.70       16-lead LFCSP The quad-channel AD5144 can be designed into circuits as the gain control for buck/boost controller power supply applications together with ADI's ADP5034 dual-channel, 3-MHz, 1200-mA buck regulators with two 300-mA LDOs.
