TS925IN - Quad Rail-to-Rail Op Amp, 4 MHz | STMicroelectronics
부품 번호: TS925IN ✗ 단종TS925IN 개요
An operational amplifier is an active analog semiconductor that uses high open-loop gain to amplify the difference between two input voltages. The TS925IN belongs to the general-purpose operational-amplifier family within the broader amplifier and analog IC hierarchy. Rail-to-rail input and output behavior allows the amplifier to operate across a substantial portion of its supply range, while the four-circuit arrangement consolidates four amplifier channels into one package. These characteristics make the device suitable for sensor interfaces, audio paths, instrumentation, and control-system signal chains.
The main features of the TS925IN include four amplifier sections, a 4 MHz gain-bandwidth product, rail-to-rail operation, high output-current capability, standby mode, and an adjustable phantom-ground arrangement. Standby support can reduce active power consumption when signal handling is not required. The adjustable phantom-ground function can provide an internal reference point for noninverting amplifier configurations, which can simplify some gain-stage layouts and reduce the number of external reference components.
The TS925IN is designed for general-purpose analog amplification rather than precision measurement or specialized high-voltage operation. Its four integrated channels can reduce board area compared with separate single or dual amplifier packages. Design engineers must still account for input common-mode range, output swing, supply voltage, stability, output-current demand, and the effect of the phantom-ground network when assigning signal levels. Because the accessible product records do not expose the complete electrical-limit table, exact slew rate, input bias current, output-current limit, and temperature limits should be confirmed in the manufacturer datasheet before release.
Typical uses include four-channel sensor buffering, low-frequency audio amplification, industrial measurement interfaces, analog control loops, and general instrumentation. The 16-DIP package is appropriate for through-hole designs where insertion and inspection are important, although it occupies more PCB area than comparable surface-mount packages. The four-channel architecture is especially useful when four channels must be amplified consistently and nearby to the source or destination circuitry.
A practical design choice is to keep feedback resistors close to the relevant amplifier pins, route high-impedance input traces away from switching nodes, and decouple each supply rail near the package. Confirm that the required output amplitude remains inside the usable output swing. For systems using standby or phantom ground, verify startup, shutdown, and settling behavior in the final signal-chain configuration rather than treating those features as isolated block-level functions.
This page consolidates the verified product identity, package information, functional characteristics, sourcing workflow, replacement constraints, and application guidance for the TS925IN. It also distinguishes documented drop-in substitutes from differently packaged family members, helping engineers avoid assuming that a similar amplifier description guarantees footprint, pin, or electrical compatibility.

일반적인 애플리케이션
TS925IN 적합 용도: 6 애플리케이션s: Four-Channel Sensor Buffering, Industrial Measurement Interfaces, General-Purpose Audio Signal Conditioning, Analog Control and Feedback Loops, Data-Acquisition Signal Conditioning, Portable and Low-Power Monitoring.
Four-Channel Sensor Buffering
The TS925IN is suitable for conditioning outputs from four sensors located in the same measurement area because its four amplifier channels provide a consolidated general-purpose analog front end. The documented 4 MHz gain-bandwidth product supports the moderate bandwidth typically required by temperature, position, and level sensors, while rail-to-rail input and output behavior helps preserve signal range as the supply changes. Place each amplifier close to its source to minimize high-impedance trace length, and confirm input bias current, common-mode limits, and offset voltage against the manufacturer datasheet before committing the design.
추천
Industrial Measurement Interfaces
The TS925IN can support low-frequency industrial instrumentation paths that require four amplified channels and flexible reference arrangements. Its rail-to-rail input and output characteristics are useful when sensor excitation and measurement levels vary within the available supply range, while the adjustable phantom ground can simplify selected noninverting gain stages. The high-output-current capability also makes the device relevant for driving moderate downstream loads. Validate sensor excitation levels, input protection, grounding strategy, calibration stability, and factory test tolerances before using it in production measurement equipment.
추천
General-Purpose Audio Signal Conditioning
The TS925IN can condition multiple general-purpose audio signals because it combines four amplifier channels with a 4 MHz gain-bandwidth product and rail-to-rail output capability. It is appropriate for line-level preamplification, headphone-driver interface stages, mixer subcircuits, and active balancing networks where the signal remains within the documented operating limits. The high output-current capability can improve drive into moderate loads, although the exact load capability must be checked. Keep feedback networks compact, maintain a low-impedance return path, and assess output distortion and stability for the selected gain and load.
추천
Analog Control and Feedback Loops
The TS925IN is useful in control and feedback systems where several low-frequency error or drive signals require independent amplification. Its 4 MHz gain-bandwidth product provides ample headroom for many slow control loops, while the four-channel arrangement reduces component count and simplifies board partitioning. Rail-to-rail operation helps maintain usable signal swing in single-supply systems, and standby mode can reduce activity when the controlled subsystem is idle. Compensation and stability analysis remain essential, particularly when the amplifier drives capacitive loads or operates near the edge of its output range.
추천
Data-Acquisition Signal Conditioning
The TS925IN can provide the analog gain and buffering stage in a four-channel data-acquisition front end. Its rail-to-rail input capability supports a broad class of low-voltage sensor outputs, and the 4 MHz gain-bandwidth product is suitable for many sensors whose bandwidth is well below that limit. Four channels packaged together can reduce board area and keep analog paths compact. The adjustable phantom-ground feature may simplify shared-reference gain networks. Engineers should confirm input capacitance, bias-current effects, noise, offset, and settling behavior, especially for high-impedance sources.
추천
Portable and Low-Power Monitoring
The TS925IN can be used in battery-powered monitoring equipment when multiple low-bandwidth signals must be amplified and standby operation is valuable for reducing consumption during idle periods. Its four-channel organization allows one package to handle several related monitoring inputs, while rail-to-rail input and output behavior improves utilization of the available supply range. The 16-DIP format favors robust through-hole assembly, though it occupies more board area than a surface-mount quad amplifier. Battery design work should verify supply voltage, sleep current, start-up time, and output settling under the actual power-management sequence.

선택 가이드
설계 노트
Do not treat TS925AIN or TS925ID as a confirmed substitute for TS925IN. The available comparison records identify TS925ID as an SOIC-16 while TS925IN uses a 16-DIP, making it a different PCB footprint. TS925AIN may belong to the same family, but its package, pin assignments, electrical limits, and control functions must be checked against the manufacturer documentation before it is described as drop-in compatible.
Assign the amplifier layout by function and keep each input, feedback component, and output path physically short. Because TS925IN contains four channels in one 16-DIP package, route sensitive channels away from the pins associated with power, standby control, and phantom-ground circuitry. Provide a low-impedance ground reference and place input and output decoupling close to the relevant package pins to reduce shared-impedance and pickup effects.
The documented 4 MHz gain-bandwidth product does not guarantee 4 MHz closed-loop bandwidth in every configuration. Determine the actual noise gain from the feedback network, verify stability with the intended load and output capacitance, and confirm output swing at the required signal amplitude. For high-impedance sensors, minimize input-node leakage, use guarded routing where appropriate, and check bias-current-induced errors before calibration.
규정 준수 정보
The accessible product records do not state the TS925IN compliance status. RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status remain unconfirmed.
