Analog Devices’ Non-Volatile Digital Potentiometers Deliver Industry’s Highest Bandwidth And Lowest Resistance Tolerance

Analog Devices, Inc. (ADI) today introduced a series of non-volatile single-, dual- and quad-channel digital potentiometers (digiPOTs) that improve 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

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
