GENERAL DESCRIPTION
The AD5241/AD5242 provides a single-/dual-channel, 256-
position digitally controlled variable resistor (VR) device. These
devices perform the same electronic adjustment function as a
potentiometer, trimmer or variable resistor. Each VR offers a
completely programmable value of resistance, between the A
terminal and the wiper, or the B terminal and the wiper. For
AD5242, the fixed A-to-B terminal resistance of 10 k
, 100 k
or 1 M
has a 1% channel-to-channel matching tolerance.
Nominal temperature coefficient of both parts is 30 ppm/
°
C.
Wiper position programming defaults to midscale at system
power ON. Once powered, the VR wiper position is programmed
by an I
2
C-compatible 2-wire serial data interface. Both parts
have available two extra programmable logic outputs that
enable users to drive digital loads, logic gates, LED drivers, and
analog switches in their system.
The AD5241/AD5242 is available in surface-mount (SO-14/-16)
packages and, for ultracompact solutions, TSSOP-14/-16 pack-
ages. All parts are guaranteed to operate over the extended
industrial temperature range of –40
°
C to +85
°
C. For 3-wire,
SPI-compatible interface applications, please refer to AD5200,
