TS514AIN Equivalent & Substitute Parts

Part Overview

The TS514AIN is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a 4-circuit integrated circuit in a 14-DIP package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The TS514AIN operates across a wide supply voltage range of 6 V to 30 V and maintains performance across industrial temperature ranges from -40°C to 125°C. Substitute parts must maintain functional compatibility while accommodating the obsolete status of the original component.

Engineering Selection Recommendations

AD704JNZ (Analog Devices Inc., Active Status): Pin-compatible 4-circuit general-purpose amplifier in 14-DIP package. Operates within 4 V to 36 V supply range, overlapping the TS514AIN specification. ROHS3 compliant with MSL 1 rating. Lower input bias current (0.1 pA) and reduced input offset voltage (50 µV) compared to TS514AIN. Reduced slew rate (0.1 V/µs) and gain bandwidth product (0.8 MHz) require application-specific evaluation for frequency-dependent circuits.

LM324AN/NOPB (Texas Instruments, Active Status): Pin-compatible 4-circuit general-purpose amplifier in 14-DIP package. Operates within 3 V to 32 V supply range. ROHS3 compliant with MSL 1 rating. Higher output current capability (40 mA per channel) exceeds TS514AIN specification. Lower minimum supply voltage (3 V) extends application flexibility. Operating temperature range (0°C to 70°C) is narrower than TS514AIN; not suitable for extended industrial temperature applications.

LM2900N (Texas Instruments, Last Time Buy Status): Pin-compatible 4-circuit general-purpose amplifier in 14-DIP package. Operates within 4.4 V to 32 V supply range. ROHS3 compliant. Extended slew rate (20 V/µs) and gain bandwidth product (2.5 MHz) support higher-frequency applications. Operating temperature range (-40°C to 85°C) accommodates industrial applications. Last Time Buy status indicates limited future availability.

OP497GPZ (Analog Devices Inc., Active Status): Pin-compatible 4-circuit general-purpose amplifier in 14-DIP package. Operates within 4 V to 40 V supply range, providing extended maximum supply voltage. ROHS3 compliant with MSL 1 rating. Extended operating temperature range (-40°C to 85°C) supports industrial applications. Lower input bias current (60 pA) and reduced input offset voltage (80 µV) improve precision. Reduced slew rate (0.15 V/µs) and gain bandwidth product (0.5 MHz) require application-specific evaluation.

LT1058ACN#PBF (Analog Devices Inc., Active Status): Pin-compatible 4-circuit J-FET amplifier in 14-DIP package. Operates within 20 V to 36 V supply range; minimum supply voltage (20 V) exceeds TS514AIN minimum (6 V), restricting application compatibility. ROHS3 compliant with MSL 1 rating. Extremely low input bias current (5 pA) and highest gain bandwidth product (5 MHz) among substitutes. Suitable for precision, high-impedance, and high-frequency applications where supply voltage constraints are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the TS514AIN be directly replaced with any of these substitute parts?

A: All listed substitute parts maintain 14-DIP through-hole package compatibility and 4-circuit configuration, enabling direct pin-compatible replacement. However, electrical parameter differences require application-specific evaluation. Verify supply voltage requirements, frequency response, and temperature operating range compatibility with your circuit design before substitution.

Q: Which substitute part is most suitable for industrial temperature applications?

A: LM2900N and OP497GPZ both support operating temperature ranges of -40°C to 85°C, meeting industrial specifications. The TS514AIN operates to 125°C, which neither substitute fully matches. For applications requiring the full -40°C to 125°C range, alternative solutions outside this substitute list may be necessary.

Q: What is the significance of the "Last Time Buy" status for LM2900N?

A: Last Time Buy status indicates that Texas Instruments has announced end-of-life for this component. While currently available, future procurement may become restricted. For new designs or long-term production requirements, Active status parts (AD704JNZ, LM324AN/NOPB, OP497GPZ, LT1058ACN#PBF) are recommended.

Q: How do input bias current differences affect circuit performance?

A: Input bias current determines the DC offset voltage developed across input impedances. The TS514AIN specifies 50 nA input bias current. Substitutes range from 0.1 pA (AD704JNZ) to 60 pA (OP497GPZ). Lower input bias current reduces offset errors in high-impedance circuits. LT1058ACN#PBF provides the lowest input bias current (5 pA), suitable for precision instrumentation applications.

Q: Is the LT1058ACN#PBF suitable as a direct replacement?

A: LT1058ACN#PBF provides pin-compatible 14-DIP packaging and 4-circuit configuration. However, its minimum supply voltage requirement (20 V) exceeds the TS514AIN minimum (6 V). Direct replacement is only feasible in circuits operating at 20 V or higher. For circuits designed around the TS514AIN's 6 V minimum supply, LT1058ACN#PBF is not compatible.

Q: What are the compliance and regulatory considerations for substitution?

A: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the TS514AIN regulatory profile. Moisture Sensitivity Level (MSL) ratings are consistent across all substitutes (MSL 1 or Not Applicable), indicating no additional handling requirements. ECCN and HTSUS classifications remain unchanged, supporting equivalent export and procurement procedures.

Q: How do slew rate and gain bandwidth product differences impact circuit design?

A: Slew rate determines the maximum rate of output voltage change; gain bandwidth product defines the frequency response limit. The TS514AIN specifies 1.5 V/µs slew rate and 3 MHz gain bandwidth product. Substitutes range from 0.1 V/µs to 20 V/µs slew rate and 0.5 MHz to 5 MHz gain bandwidth product. Applications requiring high-speed signal processing or high-frequency operation must select substitutes with matching or superior specifications.

Q: Which substitute offers the best overall performance match to the TS514AIN?

A: LM2900N provides the closest performance match, with 2.5 MHz gain bandwidth product (versus 3 MHz), 20 V/µs slew rate (exceeding 1.5 V/µs), and industrial temperature range (-40°C to 85°C). Supply voltage range (4.4 V to 32 V) overlaps the TS514AIN specification. However, Last Time Buy status limits long-term availability. For sustained production, OP497GPZ offers comparable performance with Active status and extended supply voltage range (4 V to 40 V).
