CAT5271, CAT5273
Dual 256‐position I2C
Compatible Digital
Potentiometers (POTs)
The CAT5271 and CAT5273 are dual 256-position digital
programmable linear taper potentiometers ideally suited for replacing
mechanical potentiometers and variable resistors.
The wiper settings are controlled through an I2C-compatible digital
interface. Upon power-up, the wiper assumes a midscale position and
may be repositioned anytime after the power is stable. The devices can
be programmed to go to a shutdown state during operation.
The CAT5271 and CAT5273 operate from 2.7 V to 5.5 V, while
consuming less than 2 mA. This low operating current, combined with
a small package footprint, makes them ideal for battery-powered
portable applications.
The CAT5271 and CAT5273, designed as pin for pin replacements
for the AD5243 and AD5248, are offered in the 10-lead MSOP
package and operate over the 40C to +85C industrial temperature
range.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Maximum terminal current is bounded by the maximum current handling of the switches, maximum power dissipation of the package, and
maximum applied voltage across any two of the A, B, and W terminals at a given resistance.

2. VA applies to both A1 and A2, VB applies to both B1 and B2.
3. Typical specifications represent average readings at +25C and VDD = 5 V.
4. Resistor position nonlinearity error RINL is the deviation from an ideal value measured between the maximum resistance and the
minimum resistance wiper positions. RDNL measures the relative step change from ideal between successive tap positions. Parts are
guaranteed monotonic.
5. CAT5271: VAB = VDD, Wiper (VW) = no connect. CAT5273: VWB = VDD.
6. INL and DNL are measured at VW with the digital potentiometer configured as a potentiometer divider similar to a voltage output D/A
converter. VA = VDD and VB = 0 V. DNL specification limits of 1 LSB maximum are guaranteed monotonic operating conditions.
7. Resistor terminals A, B, W have no limitations on polarity with respect to each other.
8. Guaranteed by design and not subject to production test.
9. Maximum terminal current is bounded by the maximum current handling of the switches, maximum power dissipation of the package, and
maximum applied voltage across any two of the A, B, and W terminals at a given resistance.
10. All dynamic characteristics use VDD = 5 V.
