Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS925IDT is determined by alignment across the following critical parameters:

Package Compatibility: The TS925IDT utilizes a 16-SOIC surface mount package. Substitute components must maintain identical or compatible package footprints to ensure direct PCB integration without layout modifications.

Circuit Configuration: The device contains four independent operational amplifier circuits. Substitute parts must provide equivalent circuit count to maintain functional parity in multi-channel applications.

Output Characteristics: Rail-to-rail output capability is a defining feature. Substitute components must support rail-to-rail output to preserve signal swing performance across the full supply voltage range.

Electrical Performance: Key performance metrics including slew rate, gain bandwidth product, input bias current, input offset voltage, and output current drive capability determine functional equivalence. Substitutes must meet or exceed these specifications within acceptable application tolerances.

Supply Voltage Range: The TS925IDT operates across 2.7 V to 12 V. Substitute components must support this supply voltage envelope or a compatible subset thereof.

Operating Temperature Range: The device functions across -40°C to 125°C. Substitute components must maintain this temperature specification or an equivalent industrial-grade range.

Compliance and Regulatory Status: RoHS3 compliance and MSL rating are mandatory for production continuity. All substitute components must maintain equivalent or superior compliance status.

Parameter Comparison

Engineering Selection Recommendations

TS924IDT Substitution: The TS924IDT is an active product from STMicroelectronics with identical electrical performance characteristics to the TS925IDT, including matching slew rate, gain bandwidth product, input bias current, input offset voltage, and output current drive. Both devices maintain the same operating temperature range and supply voltage specifications. The primary distinction is package configuration: the TS924IDT uses a 14-SOIC package versus the 16-SOIC of the TS925IDT. This substitution requires PCB layout modification to accommodate the different pin count and package footprint. The TS924IDT carries AEC-Q100 automotive qualification and demonstrates significantly reduced supply current consumption (1 mA versus 6 mA), providing additional design benefits. This component is recommended for applications where package footprint modification is acceptable and where reduced power consumption is advantageous.

TLV2475AIDR Substitution: The TLV2475AIDR is an active Texas Instruments CMOS operational amplifier with four circuits in a 16-SOIC package, maintaining direct package compatibility with the TS925IDT. This device exhibits superior input characteristics with input bias current of 2.5 pA and input offset voltage of 250 µV, substantially lower than the TS925IDT specifications. The TLV2475AIDR delivers marginally higher slew rate (1.5 V/µs) and significantly reduced supply current consumption (600 µA total versus 6 mA). However, the maximum supply voltage is limited to 6 V compared to the TS925IDT's 12 V maximum, and the gain bandwidth product is reduced to 2.8 MHz. Output current per channel is also reduced to 35 mA versus 80 mA. This substitution is suitable for applications operating within the 2.7 V to 6 V supply range where superior input offset characteristics and lower power consumption are required. Direct PCB footprint compatibility eliminates layout modification requirements.

Product Status Consideration: Both substitute components are active products with established supply chains, addressing the obsolescence status of the TS925IDT. Selection between substitutes depends on specific application requirements regarding supply voltage range, output current capability, and package footprint constraints.

Frequently Asked Questions (FAQ)

Q: Can the TS924IDT directly replace the TS925IDT without PCB modifications?

A: No. While the TS924IDT provides equivalent electrical performance, it uses a 14-SOIC package compared to the TS925IDT's 16-SOIC package. The different pin count and package footprint require PCB layout modifications. However, the electrical functionality and performance characteristics are fully compatible.

Q: What is the primary advantage of the TLV2475AIDR over the TS925IDT?

A: The TLV2475AIDR offers superior input characteristics with input bias current of 2.5 pA (versus 15 nA) and input offset voltage of 250 µV (versus 3 mV). Additionally, it consumes significantly less supply current at 600 µA total compared to 6 mA. The 16-SOIC package provides direct PCB footprint compatibility, eliminating layout modifications.

Q: Are there supply voltage limitations when substituting with the TLV2475AIDR?

A: Yes. The TLV2475AIDR operates across 2.7 V to 6 V, whereas the TS925IDT supports 2.7 V to 12 V. Applications requiring supply voltages above 6 V cannot use the TLV2475AIDR as a substitute. The TS924IDT maintains the full 2.7 V to 12 V supply range.

Q: Does the TS924IDT maintain the same output current capability as the TS925IDT?

A: Yes. Both the TS924IDT and TS925IDT provide 80 mA output current per channel, ensuring equivalent drive capability for load applications.

Q: Which substitute component requires no PCB modifications?

A: The TLV2475AIDR maintains the same 16-SOIC package footprint as the TS925IDT, allowing direct PCB substitution without layout modifications. The TS924IDT requires PCB redesign due to its 14-SOIC package configuration.

Q: Are both substitute components RoHS3 compliant?

A: Yes. Both the TS924IDT and TLV2475AIDR are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the compliance status of the TS925IDT.

Q: What is the key performance trade-off when using the TLV2475AIDR?

A: The TLV2475AIDR reduces gain bandwidth product to 2.8 MHz (from 4 MHz) and output current to 35 mA per channel (from 80 mA). These reductions are offset by superior input characteristics and lower power consumption. Application-specific frequency response and output current requirements determine suitability.

Q: Can the TS924IDT be used in automotive applications?

A: Yes. The TS924IDT carries AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. The TS925IDT and TLV2475AIDR do not specify automotive qualification.
