THS14F03IPFB Equivalent & Substitute Parts

Part Overview

The THS14F03IPFB is a 14-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for data acquisition applications requiring single-channel differential input conversion at 3 MHz sampling rate. The device integrates a programmable gain amplifier (PGA), sample-and-hold circuit, and ADC in a 48-TQFP surface mount package.

This part is classified as obsolete. Locating equivalent substitute components is necessary to support ongoing production requirements, maintenance operations, and system redesigns where continued sourcing of the original part is no longer feasible through standard distribution channels.

• Sampling Rate: 3 MHz
• Input Configuration: Single differential input
• Architecture: Pipelined ADC with integrated PGA and S/H
• Data Interface: Parallel output
• Supply Voltage Ranges: 3V to 3.6V (both analog and digital)
• Operating Temperature: -40°C to 85°C
• Package: 48-TQFP (7x7) surface mount

The THS1403IPFB meets all substitution criteria. Both devices share identical electrical specifications, functional architecture, and physical packaging, enabling direct replacement in applications currently using the THS14F03IPFB.

Parameter Comparison

Engineering Selection Recommendations

The THS1403IPFB is the direct equivalent substitute for the THS14F03IPFB. Selection of the THS1403IPFB is supported by the following factors:

• All electrical parameters match exactly, including resolution, sampling rate, supply voltage ranges, and operating temperature specifications
• Identical package and pinout (48-TQFP 7x7) enable direct PCB compatibility without layout modifications
• Both devices maintain equivalent RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements
• The THS1403IPFB carries active product status, ensuring continued availability and manufacturer support, whereas the THS14F03IPFB is obsolete
• Moisture sensitivity level and handling requirements are identical (MSL 2, 1 Year)

No additional design modifications, firmware updates, or application circuit changes are required when substituting the THS1403IPFB for the THS14F03IPFB.
