AD514x and AD512x Digital Potentiometers

Analog Devices' offers a series of non-volatile single-, dual- and quad-channel digital potentiometers (digiPOTs) which improve component matching in industrial and communication control systems by featuring resistance tolerance of ±1 percent (typical). The additional 11 digiPOTs in ADI’s AD514x and AD512x series also achieve a 3 MHz bandwidth that is 50 percent higher than the closest competitor and enables faster system response time. The devices offer the industry's lowest temperature coefficient performance over the temperature range of -40°C to +125°C.

Analog Devices' 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; and all featuring 4 kV ESD protection.
