X9315TS-2.7

Digital Potentiometers Overview

The X9315TS-2.7 is a digitally controlled potentiometer (XDCP) from the Renesas X9315 series, manufactured by Intersil/Renesas. It features a single potentiometer with 32 taps and a linear taper. The device operates on a serial 3-wire interface (CS, U/D, INC) for wiper position control and includes nonvolatile memory to retain settings across power cycles. Electrical specifications include a resistance range of 10kΩ to 100kΩ, a supply voltage range of 2.7V to 5.5V, and a typical operating current of 50µA. It is housed in an 8-pin SOIC package.

Digital Potentiometers Feature Summary

• Nonvolatile Memory: Retains wiper position upon power-up.
• Linear Taper: Provides precise resistance adjustment.
• Low Power Consumption: Typical operating current of 50µA.
• Wide Supply Voltage: Operates between 2.7V and 5.5V.

Digital Potentiometers Applications

• Audio volume control
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Check RoHS compliance status as it varies by production batch. Confirm package type (SOIC-8) and resistance value (10kΩ/100kΩ variants exist within the series). Ensure storage conditions meet humidity sensitivity requirements if applicable.

Digital Potentiometers Selection Notes

Select based on required resistance value (10kΩ or 100kΩ) and interface compatibility (3-wire serial). Verify that the 32-tap resolution meets application precision needs. Consider the ±20% tolerance and temperature coefficient (±300ppm/°C) for environmental stability. Ensure the 2.7V minimum supply voltage aligns with system power rails.

Digital Potentiometers Part Context

Part of the X9315 family of low-noise, low-power digital potentiometers. Designed as a drop-in replacement for mechanical potentiometers in space-constrained PCB designs. Manufactured under the Intersil brand prior to the Renesas acquisition.

Digital Potentiometers Replacement Considerations

Compatible replacements include other X9315 variants with matching resistance and package (e.g., X9315WSZ, X9315USZ). Verify pinout compatibility and interface protocol before substitution.
