LMP91002SD/NOPB

Analog Front End (AFE) Overview

The LMP91002SD/NOPB is a configurable analog front-end (AFE) potentiostat designed for low-power chemical sensor applications. Manufactured by Texas Instruments, it operates within an analog supply voltage range of 2.7 V to 3.6 V. The device supports a wide operating temperature range from -40°C to +85°C and is housed in a WSON-14 package. It integrates signal conditioning and control functions necessary for interfacing with electrochemical sensors, facilitating precise measurement in portable or battery-operated systems.

Analog Front End (AFE) Feature Summary

• Configurable Potentiostat AFE architecture for electrochemical sensing
• Operates on a single analog supply voltage between 2.7 V and 3.6 V
• Available in a compact WSON-14 surface-mount package
• Rated for industrial temperatures from -40°C to +85°C

Analog Front End (AFE) Applications

• Low-power chemical sensor interfaces
• Electrochemical detection systems
• Portable diagnostic devices requiring potentiostat functionality

Analog Front End (AFE) Procurement Notes

Verify the specific suffix 'SDX' against the requested model 'LDP91002SD'. The available data indicates 'LMP91002SDX/NOPB' is supplied in reels with a factory pack quantity of 4500 units. Confirm moisture sensitivity level requirements and storage conditions prior to procurement, as the component is listed as humidity sensitive.

Analog Front End (AFE) Selection Notes

Select this component when a dedicated potentiostat AFE is required for electrochemical sensors. Ensure the system power budget accommodates the 2.7 V to 3.6 V supply range. Compare with the LMP91000 series if a wider input voltage range up to 5.25 V is needed, noting that the LMP91002 is optimized for lower voltage operation.

Analog Front End (AFE) Part Context

This part belongs to the LMP91002 family of configurable AFEs. It shares the WSON-14 footprint and core potentiostat functionality with related models like the LMP91000, but differs in specified supply voltage constraints. It is distinct from the discontinued LMP91050, which utilizes an MSOP-10 package and supports higher voltages up to 5.5 V.

Analog Front End (AFE) Replacement Considerations

The LMP91000SD/NOPB is a related variant within the same product family. While both are potentiostat AFEs in WSON-14 packages, the LMP91000 supports a broader analog supply range (2.7 V to 5.25 V). Verify voltage compatibility before substituting.
