Overview
The AD5122BCPZ10-RL7 is a dual-channel, nonvolatile digital potentiometer from Analog Devices Inc., featuring 128 adjustment positions and an SPI-compatible interface. It operates within a supply voltage range of 2.3 V to 5.5 V with a logic supply of 1.8 V to 5.5 V. The device offers ±8% maximum resistor tolerance and a low temperature coefficient of 35 ppm/°C. Key electrical parameters include a 3 MHz bandwidth, ±6 mA wiper current capability, and fast start-up time under 75 µs. It is housed in a compact 16-lead, 3 mm × 3 mm LFCSP package and supports single- or dual-supply operation across an extended industrial temperature range of −40°C to +125°C.
Feature Summary
- Dual-channel architecture with 128-position resolution and nonvolatile EEPROM storage for power-up retention.
- SPI-compatible serial interface allowing independent programming and readback of wiper registers and memory contents.
- Linear gain setting mode via INDEP pin enables independent programming of string resistors for accurate matching.
- AEC-Q100 qualified for automotive applications with wide operating temperature range (−40°C to +125°C).
Applications
- Portable electronics level adjustment
- LCD panel brightness and contrast controls
- Programmable filters, delays, and time constants
- Programmable power supplies
Procurement Notes
Verify the specific ordering suffix BCPZ10-RL7 against the manufacturer's official datasheet to confirm package type (LFCSP) and tape/reel packaging details. Ensure compatibility with system requirements for SPI interface timing and voltage levels before procurement.
Selection Notes
Select this component for applications requiring precise analog signal adjustment with nonvolatile memory retention. Consider the 128-position resolution and ±8% tolerance for open-loop control. Verify that the 3 mm × 3 mm LFCSP package fits the PCB layout constraints and thermal design requirements.
Part Context
This part belongs to the AD5122/AD5142 family of dual-channel digital potentiometers. The AD5122 variant specifically provides 128 positions, whereas the AD5142 offers 256 positions. Both share similar electrical characteristics but differ in resolution and nonlinearity specifications.
Replacement Considerations
The AD5122BRUZ10 is a parameter-equivalent alternative available in a TSSOP package. Verify pinout compatibility and package dimensions when substituting between LFCSP and TSSOP variants.
