THS1240IPHP Equivalent & Substitute Parts

Part Overview

The THS1240IPHP is a 12-bit pipelined analog-to-digital converter manufactured by Texas Instruments, housed in a 48-HTQFP package. This data acquisition component features a single differential input with a 40 MHz sampling rate and operates on dual 5V supply rails. The device is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and component procurement strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the THS1240IPHP is determined by the following core parameters: 12-bit resolution, pipelined architecture, differential input capability, parallel data interface, 5V dual supply operation, and -40°C to 85°C temperature range. The ADS807E qualifies as a functional equivalent based on matching all critical electrical specifications. While the ADS807E operates at a higher sampling rate (53 MHz versus 40 MHz) and supports both differential and single-ended inputs, these represent performance enhancements rather than incompatibilities. The primary distinction is packaging: the ADS807E uses a 28-SSOP form factor compared to the 48-HTQFP of the original part, requiring PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The ADS807E is the qualified substitute for the THS1240IPHP based on electrical parameter equivalence and active product status. The THS1240IPHP's obsolete classification creates supply chain risk; the ADS807E addresses this through active manufacturing and documented availability. The ADS807E's higher sampling rate (53 MHz) provides performance margin above the original 40 MHz specification, supporting system upgrades without functional degradation. The ADS807E achieves ROHS3 compliance, whereas the THS1240IPHP is RoHS non-compliant, making the substitute preferable for new designs and regulatory requirements. Both devices maintain REACH Unaffected status and EAR99 export classification. Package transition from 48-HTQFP to 28-SSOP requires PCB redesign but does not affect electrical functionality or signal integrity when proper layout practices are observed.

Frequently Asked Questions (FAQ)

Q: Can the ADS807E directly replace the THS1240IPHP without PCB modification?

A: No. The ADS807E uses a 28-SSOP package versus the 48-HTQFP of the original part. PCB layout redesign is required. However, electrical functionality is fully compatible, and the smaller package footprint may reduce board space requirements.

Q: What is the impact of the higher 53 MHz sampling rate on system performance?

A: The ADS807E's 53 MHz sampling rate exceeds the THS1240IPHP's 40 MHz specification. This represents enhanced performance capability and does not create compatibility issues. Systems designed for 40 MHz operation will function correctly with the higher-speed substitute.

Q: Are there input configuration differences between these devices?

A: The THS1240IPHP supports differential input only. The ADS807E supports both differential and single-ended inputs. For applications using differential configuration, both devices are equivalent. The ADS807E's expanded input flexibility provides design flexibility for future modifications.

Q: What compliance advantages does the ADS807E offer?

A: The ADS807E is ROHS3 compliant, while the THS1240IPHP is RoHS non-compliant. For new designs and applications subject to RoHS regulations, the ADS807E is the required choice. Both devices maintain REACH Unaffected status.

Q: Is the ADS807E currently available for procurement?

A: Yes. The ADS807E is classified as Active product status with documented inventory availability, whereas the THS1240IPHP is obsolete. This makes the ADS807E the practical choice for ongoing component sourcing.

Q: Do supply voltage requirements differ between these parts?

A: No. Both devices require identical 5V analog and 5V digital supply voltages. Power distribution design remains unchanged during substitution.

Q: What is the temperature operating range compatibility?

A: Both devices operate across the identical -40°C to 85°C temperature range. Thermal design and operating environment specifications remain unchanged.
