The datasheet introduces the features and functions of AD5204/AD5206. AD5204/AD5206 are 4/6-channel digital potentiometers that can replace mechanical potentiometers. They have 256 positions and can achieve accurate electronic adjustment
The AD5204/AD5206 family provides digitally controlled variable resistors that replace mechanical potentiometers in instrumentation, programmable voltage‑to‑current conversion, and filter applications. Each channel contains a fixed resistor and a wiper that can be positioned to any of 256 steps via a 3‑wire SPI‑compatible serial interface, with optional mid‑scale preset on power‑up.
The devices operate over an industrial temperature range (‑40 °C to +85 °C) and support single‑supply (+2.7 V to +5.5 V) or dual‑supply (±2.7 V) operation. They are offered in PDIP, SOIC, TSSOP, and 32‑lead LFCSP packages, and include features such as a reset pin for mid‑scale positioning and programmable terminal resistance options of 10 kΩ, 50 kΩ, or 100 kΩ.
| Channels | 4 (AD5204) / 6 (AD5206) |
|---|---|
| Resolution | 256 positions |
| Terminal resistance options | 10 kΩ, 50 kΩ, 100 kΩ |
| Supply voltage | +2.7 V to +5.5 V single‑supply; ±2.7 V dual‑supply |
| Resistance tolerance | ±30 % |
The devices operate from +2.7 V to +5.5 V on a single supply, or from ±2.7 V on a dual‑supply configuration.
The AD5206 provides six independent programmable channels.
The PR pin forces all wipers to the mid‑scale position by loading 0x80 into the VR latch.
They are offered in 24‑lead PDIP, SOIC, TSSOP, and a 32‑lead LFCSP (5 mm × 5 mm) package.
