AD5204BCPZ10-REEL7

Overview

The AD5204BCPZ10-REEL7 is a four-channel, 256-position digitally controlled variable resistor (VR) from Analog Devices. It operates on a single supply of +2.7 V to +5.5 V or dual supplies of ±2.7 V. The device features a nominal terminal resistance of 10 kΩ with a temperature coefficient of 700 ppm/°C. Control is managed via a 3-wire SPI-compatible serial interface using an 11-bit data word. Each channel includes a dedicated VR latch for independent programming. The component supports power-on midscale preset and offers shutdown capabilities to minimize power consumption.

Feature Summary

• Four independently programmable channels with 256 positions
• Nominal resistance of 10 kΩ with linear taper
• 3-wire SPI-compatible serial interface with daisy-chain capability
• Power-on midscale preset and hardware reset functionality

Applications

• Mechanical potentiometer replacement
• Instrumentation gain and offset adjustment
• Programmable voltage-to-current conversion
• Programmable filters, delays, and time constants
• Line impedance matching

Procurement Notes

Verify the package type matches the design requirements, as the AD5204 series is available in multiple packages including TSSOP and LFCSP. Confirm the resistance value suffix corresponds to the 10 kΩ specification. Ensure the ordering suffix indicates the reel packaging format required for automated assembly processes.

Selection Notes

Select this component when a multi-channel digital solution is needed to replace mechanical potentiometers. The 10 kΩ resistance value is suitable for general-purpose signal conditioning. Consider the 700 ppm/°C temperature coefficient for thermal stability requirements. The device supports both single and dual supply configurations, offering flexibility in system power design.

Part Context

This part belongs to the AD5204 family of 4-channel digital potentiometers. It shares functional similarities with the AD5206, which provides six channels. The BC prefix typically denotes specific manufacturing lot or quality grades within the Analog Devices portfolio, while the BCPZ suffix identifies the specific surface-mount package configuration.

Replacement Considerations

Direct replacements include other AD5204 variants with different resistance values or packages. For applications requiring more channels, the AD5206 is the compatible alternative. Ensure that any substitute maintains the same 3-wire SPI interface timing characteristics and voltage supply ranges.
