AD5204BN10

Overview

The AD5204BN10 is a four-channel, 256-position digitally controlled variable resistor (VR) device from Analog Devices. It features a nominal terminal resistance of 10 kΩ with a temperature coefficient of 700 ppm/°C. The device operates on a single supply voltage ranging from +2.7 V to +5.5 V or a dual supply of ±2.7 V. Each channel includes an independent VR latch updated via a 3-wire SPI-compatible serial interface. Key electrical characteristics include a typical wiper resistance of 50 Ω to 100 Ω and a power-on midscale preset function. The component is guaranteed to operate within the extended industrial temperature range of −40°C to +85°C.

Feature Summary

• Four independently programmable channels with 256 positions each
• Nominal end-to-end resistance of 10 kΩ
• 3-wire SPI-compatible serial data input interface
• Power-on midscale preset for fault condition recovery

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion
• Line impedance matching

Procurement Notes

Verify the ordering suffix BN10 against the manufacturer's current ordering guide to confirm package type and tape/reel specifications. Ensure the selected variant matches the required thermal performance and ESD protection levels for the target application environment.

Selection Notes

Select this component when a multi-channel digital potentiometer with 10 kΩ nominal resistance is required. Consider the 1000 V HBM ESD rating and the specific bandwidth limitations at 10 kΩ (721 kHz) if high-frequency signal processing is involved. Verify that the serial interface timing requirements align with the host microcontroller capabilities.

Part Context

The AD5204 series provides 4-channel RDACs, while the AD5206 variant offers 6 channels. Both share similar architectural features but differ in pin count and channel density. The AD5204 is available in 24-lead SOIC/TSSOP and 32-lead LFCSP packages, whereas the AD5206 is limited to 24-lead packages.

Replacement Considerations

Direct replacements include other 4-channel digital potentiometers with 10 kΩ nominal resistance and compatible serial interfaces. Check pin compatibility for SOIC-24 or TSSOP-24 packages. Verify that the substitute device supports the same voltage ranges and has comparable nonlinearity and wiper resistance specifications.
