GENERAL DESCRIPTION
The AD5200 and AD5201 are programmable resistor devices,
with 256 positions and 33 positions respectively, that can be digi-
tally controlled through a 3-wire SPI serial interface. The terms
programmable resistor, variable resistor (VR), and RDAC are
commonly used interchangeably to refer to digital potentiometers.
These devices perform the same electronic adjustment function
as a potentiometer or variable resistor. Both AD5200/AD5201
contain a single variable resistor in the compact MSOP
package. Each device contains a fixed wiper resistance at the
wiper contact that taps the programmable resistance at a point
determined by a digital code. The code is loaded in the serial
input register. The resistance between the wiper and either end
point of the programmable resistor varies linearly with respect to
the digital code transferred into the VR latch. Each variable
resistor offers a completely programmable value of resistance,
between the A terminal and the wiper, or the B terminal and the
wiper. The fixed A-to-B terminal resistance of 10 kor 50 k
has a nominal temperature coefficient of 500 ppm/°C. The VR
has a VR latch that holds its programmed resistance value. The
VR latch is updated from an SPI-compatible serial-to-parallel
shift register that is loaded from a standard 3-wire serial-input
digital interface. Eight data bits for the AD5200 and six data
bits for the AD5201 make up the data word that is clocked into
the serial input register. The internal preset forces the wiper to
the midscale position by loading 80H and 10H into AD5200 and
AD5201 VR latches respectively. The SHDN pin forces the
resistor to an end-to-end open-circuit condition on the A terminal
and shorts the wiper to the B terminal, achieving a microwatt
power shutdown state. When SHDN is returned to logic high,
the previous latch setting puts the wiper in the same resistance
setting prior to shutdown. The digital interface is still active dur-
ing shutdown so that code changes can be made that will produce
a new wiper position when the device is returned from shutdown.
All parts are guaranteed to operate over the extended industrial
temperature range of –40°C to +85°C.

NOTES
1Typicals represent average readings at 25°C and VDD = 5 V, VSS = 0 V.
2Resistor position nonlinearity error R-INL is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper posi-
tions. R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic. I W = VDD/R for both VDD = +2.7 V,
VSS = –2.7 V.
3VAB = VDD, Wiper (VW) = No connect.
4INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. V A = VDD and VB = 0 V. DNL
specification limits of ± 1 LSB maximum are Guaranteed Monotonic operating conditions.
5Resistor Terminals A, B, W have no limitations on polarity with respect to each other.
6Guaranteed by design and not subject to production test.
7Measured at the A terminal. A terminal is open-circuited in shutdown mode.
8PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.
9All dynamic characteristics use VDD = 5 V, VSS = 0 V.
Specifications subject to change without notice.
