AS1506
256-Tap Digital Potentiometer with SPI Interface and
High Endurance EEPROM
1 General Description
www.austriamicrosystems.com
Revision 1.02
1 - 17
Datasheet
The AS1506 is a linear, 256-tap digital potentiometer
specifically designed to replace discrete/mechanical
potentiometers and is ideal for applications requiring a
low-temperature-coefficient variable resistor, such as
low-drift, programmable gain, and amplifier circuit con-
figurations.
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 16
).
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 and a low-power standby mode.
The devices are available in an 8-pin TDFN 3x3mm
package.
