AS1507
Dual 256-Tap Digital Potentiometer with SPI Interface
and High Endurance EEPROM
1 General Description
Revision 1.011 - 18
Datasheet
The AS1507 is a linear, dual 256-tap digital potentiome-
ter specifically designed to replace discrete/mechanical
potentiometers and is ideal for applications requiring a
low-temperature-coefficient variable resistor.
The device is controlled via a 3-wire SPI-compatible
interface and features an internal EEPROM for storing
wiper positions.
Several device variants are available differentiated by
end-to-end resistance as shown in
Table 1
(see also
Ordering Information on page 17
).
Table 1. Standard Products
The 3-wire SPI-compatible serial interface allows com-
munication at data rates up to 5MHz. The internal
EEPROM stores the last wiper position for initialization
during power-up.
The devices are available in an TQFN 3x3mm 16-pin
package.
