Description
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 configurations.
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:
| Model |
End-to-End Resistance (kΩ) |
AS1506-10 |
10 |
AS1506-50 |
50 |
AS1506-100 |
100 |
The 3-wire SPI-compatible serial interface allows communication 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.
