What are the key features of AD8402AN10?
- 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
What is AD8402AN10 used for?
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.
