TPL8002-25PWR

Digital Potentiometers Overview

The TPL8002-25PWR is a dual digital potentiometer IC from Texas Instruments, housed in a 16-TSSOP surface-mount package. It features two independent potentiometers, each with 64 taps and a resistance value of 2.5 kΩ. The device utilizes a parallel interface for control and employs volatile arc brush memory to retain wiper positions during operation. It operates within a supply voltage range of ±2.5V to 4V and draws a typical operating current of 100 µA. The component supports an extended industrial temperature range from -40°C to +85°C and exhibits a resistance tolerance of ±30%.

Digital Potentiometers Feature Summary

• Dual-channel configuration with 64 taps per potentiometer

Digital Potentiometers Procurement Notes

Verify the specific suffix PWR indicates the 16-TSSOP package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the parallel interface requirements match the host system's I/O capabilities before procurement.

Digital Potentiometers Selection Notes

Select this component when a dual-channel digital adjustment is required with low power constraints. The 2.5 kΩ resistance value suits moderate impedance applications. Verify that the volatile memory characteristic aligns with the application's need to reset wiper positions upon power loss.

Digital Potentiometers Part Context

This part belongs to the TPL8002 series of digital potentiometers. The '25' designation specifies the 2.5 kΩ resistance value. The 'PWR' suffix denotes the 16-pin Thin Shrink Small Outline Package (TSSOP) with a 4.40mm width. It is distinct from other TI digital pot families by its specific parallel interface and dual-channel layout.

Digital Potentiometers Replacement Considerations

Check for direct pin-compatible substitutes within the TPL8002 family with different resistance values or package options. Verify interface compatibility if considering alternatives with serial interfaces, as the parallel bus requires specific logic level matching.
