概要
Description
Key points:
- 256-step (8-bit) wiper resolution for precise attenuation/gain control.
- I2C-compatible digital interface (addr/pointer controls the wiper).
- End-to-end resistance values vary by variant (e.g., 5k, 10k, 50k, 100k); operates from a suitable supply (commonly 2.7–5.5 V).
- Wiper state is stored in volatile memory, with some variants offering non-volatile memory to retain settings after power-down.
- Features include reset, programmable increment/decrement, and protections; package options vary.
Use cases: gain/attenuation control, sensor calibration, automatic offset/gain adjustments, and DAC replacement tasks. For exact specifications and pinout, consult the ADI AD524BD datasheet.
Equivalent
- Analog Devices: AD5252/AD5253
- Microchip: MCP41xx/MCP42xx (SPI) and MCP45xx/MCP46xx (I2C)
- Maxim: DS1803/DS1804 (I2C)
Note: ensure matching resistance (5k/10k/50k/100k), number of wipers, and memory type (volatile/nonvolatile).
Features
- Two potentiometers, end-to-end resistance of 100 kΩ each.
- 8-bit wiper control per pot (256 steps) for fine adjustment.
- SPI-compatible serial interface (CS, SCLK, SI, SO) for control.
- Both volatile wiper registers and nonvolatile memory for long-term retention.
- Power-on reset and defined default wiper positions.
- Wide supply range: typically 2.7 V to 5.5 V.
- Low power consumption.
- Industrial operating temperature range (typical -40°C to +85°C).
- 8-pin package (e.g., SOIC/DIP variants) suitable for compact designs.
- Applications: gain/attenuation trimming, sensor signal conditioning, calibration.
Note: exact package options and electrical specs vary by revision; consult the latest datasheet for precise current limits, tolerances, and pinout.
Pinout
- A, B: potentiometer end terminals
- W: wiper
- CS (chip select), SCK (serial clock), SI/SDI (serial data input)
- VDD: supply
- VSS: ground
(Other package variants exist, but pin functions are as above.)
