Analog Devices’ Non-Volatile Digital Potentiometers Deliver Industry’s Highest Bandwidth And Lowest Resistance Tolerance
November 06 2012 - 12:01AM
Business Wire
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.
