Overview
The AD5123BCPZ10-RL7 is a quad-channel, nonvolatile digital potentiometer featuring 128 adjustment positions and an I2C interface. It operates within a supply voltage range of 2.3 V to 5.5 V and supports single or dual-supply configurations. The device offers a maximum resistor tolerance of ±8% and a low temperature coefficient of 35 ppm/°C. Key electrical parameters include a wiper current capacity of ±6 mA for 10 kΩ variants, a bandwidth of 3 MHz, and a fast power-up restore time of less than 75 µs. It is housed in a compact 16-lead, 3 mm × 3 mm LFCSP package.
Feature Summary
- Quad-channel architecture with 128-position resolution and nonvolatile EEPROM storage.
- I2C-compatible serial interface supporting standard (100 kHz) and fast (400 kHz) modes.
- Wide operating temperature range from −40°C to +125°C.
- Linear gain setting mode for accurate resistance matching between channels.
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 suffix 'RL7' against the manufacturer's ordering guide to confirm reel packaging specifications. Ensure compatibility with the target I2C bus voltage levels and address configuration before integration. Check for moisture sensitivity classification requirements during surface mount assembly processes.
Selection Notes
Select this component when four independent digital potentiometers are required in a single package. The 10 kΩ resistance option provides higher current handling compared to the 100 kΩ variant. Consider the linear taper for applications requiring precise gain setting rather than logarithmic audio adjustments. Verify that the 128-position resolution meets the system's control granularity needs.
Part Context
This part belongs to the AD5123/AD5143 family of nonvolatile digital potentiometers. The AD5123 variant specifically provides 128 positions, whereas the AD5143 offers 256 positions. Both share similar electrical characteristics but differ in resolution and register width. The B-grade designation typically indicates specific tolerance and performance binning within the Analog Devices portfolio.
Replacement Considerations
The AD5143BCPZ10-RL7 serves as a direct functional substitute with increased 256-position resolution. For SPI interface requirements, the AD5124BCPZ10-RL7 is available. Single-channel alternatives include the AD5121BCPZ10-RL7, while dual-channel options are found in the AD5122 series.
