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

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.
