Key Features
- Dual independent 10 kΩ channels with 256-position linear taper provide fine 39 Ω per-step resistance resolution
- 3-wire SPI-compatible serial interface with daisy-chain support enables easy multi-device control from one SPI bus
- Single 5 V supply operation with ±2.5 V dual supply option covers standard analog and mixed-signal design environments
- 14-pin DIP through-hole package (JEDEC R-PDIP-T14) ideal for prototyping, breadboard, and socketed designs
Applications
The AD8402AN10 is used in programmable gain amplifier circuits, offset calibration networks, and digitally adjustable filter designs where software-controlled resistance trimming replaces mechanical potentiometers. Its 10 kΩ end-to-end resistance is well suited for op-amp feedback networks, voltage dividers, and analog signal attenuation paths in test and measurement equipment. The through-hole DIP package also makes it popular for educational laboratory boards, rapid prototyping, and legacy system maintenance where surface-mount parts are not practical.

Frequently Asked Questions
What is the end-to-end resistance of the AD8402AN10?
The AD8402AN10 has a nominal end-to-end resistance of 10 kΩ with 256 linear steps, yielding approximately 39 Ω per step. The lower resistance compared to the 50 kΩ or 100 kΩ variants makes it better suited for low-impedance signal paths and op-amp feedback networks where Johnson noise from high resistance is a concern.
How many channels does the AD8402AN10 have?
The AD8402AN10 contains two independent potentiometer channels in a single 14-pin DIP package. Each channel has its own wiper, A terminal, B terminal, and W terminal, enabling independent adjustment of two separate resistance networks without requiring two discrete devices.
What serial interface does the AD8402AN10 use?
The AD8402AN10 uses a 3-wire SPI-compatible (Microwire-style) serial interface. Wiper positions are loaded by clocking a 10-bit data word (2-bit address + 8-bit data) into the serial input. Multiple devices can be cascaded in a daisy-chain configuration from a single SPI bus using the serial output pin.
What supply voltage does the AD8402AN10 require?
The AD8402AN10 operates from a single +5 V power supply or from a dual ±2.5 V split supply. It is not compatible with 3.3 V single-supply operation, so designers migrating to lower-voltage systems should consider using the AD5162 or similar modern 3.3 V compatible digital potentiometer devices.
What package does the AD8402AN10 come in?
The AD8402AN10 is available in a 14-pin PDIP (Plastic Dual In-line Package) through-hole package with JEDEC code R-PDIP-T14. The DIP format is convenient for breadboard prototyping and socketed designs but note that the part is not RoHS compliant (Pb-free code: No), which may restrict use in new RoHS-regulated products.
