Analog Devices launched the AD514x and AD512x series of non-volatile single-, dual- and quad-channel digital potentiometers. The ADI digiPOT devices feature resistance tolerance of ±1 percent (typical). The AD514x and AD512x series improves component matching in industrial and communication control systems. Digital POT devices can be used to calibrate system tolerances or dynamically control system parameters. Nonvolatile memory digital potentiometers provide wiper setting retention after a power OFF to ON cycle. In addition, fuse link parts offer a one time program trimmer feature.
The eleven new digiPOTs in ADI’s AD514x and AD512x series offers a 3-MHz bandwidth that is 50% higher than the closest competitor. This 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 Features
