Description

The AD5293BRUZ-20-RL7 is a 20kΩ digital potentiometer from Analog Devices, offering 256-tap positions for precise resistance adjustment via SPI interface. Key features include:
- Non-volatile memory: Retains settings during power-off.
- ±20% tolerance: Ensures reliable performance.
- Single-supply (2.7V–5.5V) or dual-supply (±2.5V–±2.75V) operation.
- Low tempco (35 ppm/°C): Stable across temperature variations.
- Compact TSSOP-16 package: Suitable for space-constrained designs.
Ideal for audio control, calibration, and programmable voltage dividers, it combines digital precision with analog flexibility.

Equivalent

The AD5293BRUZ-20-RL7 is a 20kΩ digital potentiometer. Equivalent alternatives include:
- AD5292: Similar but with 100kΩ resistance.
- MAX5432: 20kΩ, 256-tap, SPI interface.
- MCP41HV51: 20kΩ, 256-tap, SPI-compatible.
- DS1803: Dual 20kΩ, I²C interface.
Check for matching specs (resistance, interface, voltage range) before substitution. For exact replacements, consult distributors like Digi-Key or Mouser.
