15-V
digital potentiometers
The
AD5260, AD5262, AD5280, and AD5282
are members of a new family of 15- V, 8-bit digital potentiometers
that perform the same electronic adjustment function as
mechanical potentiometers, trimmers, or variable resistors.
The AD5260 (single channel) and AD5262 (dual channel)
are SPI-compatible; the AD5280 (single channel) and AD5282
(dual channel) are I2C-compatible.
All
operate from a single 5- to 15-V (or dual ±5-V) power
supply, and typically consume less than 1 µA. Each features
a 35 ppm/°C coefficient for improved accuracy over the
–40ºC to 85ºC operating range. This family is designed
for applications such as bar code scanners, check readers,
security tagging systems, coin and bill changers, vending
machines, medical, security and drug detection instrumentation,
optical networking, and wireless communications. Terminal
resistance options include values of 20, 50, and 200 kW.
Additional system power savings can be achieved by using
an override shutdown feature.
The
AD5260 and AD5280 are available in TSSOP-14 packages and
cost $1.85 in 1000-piece quantities. The AD5262
and AD5282 are available in TSSOP-16 packages and cost
$2.60 1000-piece quantities.
