TS912ID 概要
An operational amplifier is an analog building block that uses high open-loop gain to amplify voltage differences while feedback determines the closed-loop behavior. A dual op-amp combines two amplifiers in one package, allowing designers to implement filters, buffers, level conversions, or paired signal-conditioning stages while reducing board area. CMOS construction supports low-power and low-noise signal-chain designs across industrial, instrumentation, communications, and consumer equipment.
The TS912ID's rail-to-rail input range includes both supply rails, while its rail-to-rail output can swing close to the upper and lower limits. The verified 800 kHz bandwidth provides useful response for general-purpose low-frequency and moderate-frequency applications, while the 1.3 V/us slew rate supports faster transitions than very low-bandwidth precision amplifiers. Two independent, frequency-compensated amplifiers are contained in the same 8-SOIC package.
Supply flexibility is central to the device: it can operate from a single 2.7 V minimum supply or from dual positive and negative rails. This makes it suitable for battery-powered instrumentation, active filtering, transducer interfaces, and general analog signal conditioning. Designers should still verify input and output common-mode limits, output-load behavior, noise, input-bias-current requirements, and stability against the conditions of the manufacturer datasheet.
Typical uses include low-frequency active filters, sensor-signal conditioning, audio and communications interface blocks, voltage buffering, and two-channel sensor amplification. The SOIC-8 package is straightforward for conventional PCB assembly and breadboard or prototype layouts, although exposed-pad thermal management is not applicable.
The primary design consideration is to place input, feedback, and decoupling components so that high-gain layouts remain stable. Keep sensitive input traces short, maintain a low-impedance ground reference, and follow the datasheet's recommended bypass capacitance. Verify the actual output swing against the load and required logic or sensor levels rather than assuming ideal rail-to-rail behavior.
This page combines verified distributor pricing, manufacturer datasheet access, same-package replacement data, and practical selection guidance. It separates explicitly published facts from parameters requiring design verification, helping engineers source TS912ID without relying on generic amplifier descriptions.

主な用途
TS912ID の用途: 7 件s: Low-Voltage Sensor Signal Conditioning, Active Audio Filtering, Battery-Powered Instrumentation, Communications Interface Buffering, Voltage Level Conditioning, Industrial Control Signal Conditioning, Data Acquisition Front End.
Low-Voltage Sensor Signal Conditioning
The TS912ID fits low-voltage sensor front ends that need two amplifiers for gain, filtering, or buffering. Its 2.7 V to 16 V supply range supports a 3.3 V rail, while the 800 kHz gain-bandwidth product provides more bandwidth than basic precision-only amplifiers. Two rail-to-rail inputs help accept sensor signals near the supply limits, and rail-to-rail outputs improve utilization of the available output range. Engineers should verify input bias current and offset against the sensor impedance, then add the supply decoupling and feedback components specified by the STMicroelectronics datasheet.
おすすめ
Active Audio Filtering
TS912ID can implement dual active-filter sections in audio and communications equipment while operating from a single supply or dual rails. The approximately 800 kHz gain-bandwidth product and 1.3 V/us slew rate are suitable for general-purpose audio-frequency filtering rather than only DC amplification. Rail-to-rail outputs help retain usable swing on low-voltage rails. The circuit must be designed around stable feedback values, and the actual output current capability and distortion should be checked against the load because those figures are not present in the supplied data.
おすすめ
Battery-Powered Instrumentation
The TS912ID is suitable for portable instrumentation powered from a low-voltage battery-derived rail because it operates from 2.7 V upward and accepts either single or dual supplies. Two independent channels can condition two measurement paths or combine a buffer with an active-filter stage. Its CMOS construction and moderate 800 kHz bandwidth align with general measurement and monitoring functions. For precision battery-powered designs, verify quiescent current, input offset, bias current, and noise directly in the datasheet; those parameters were not supplied and must not be inferred from the CMOS description alone.
おすすめ
Communications Interface Buffering
TS912ID can serve as a general-purpose dual buffer or gain stage between communications circuitry and external loads. The 1.3 V/us slew rate supports the required transitions at modest frequencies, while the 800 kHz gain-bandwidth product provides useful closed-loop response. Rail-to-rail inputs and outputs improve flexibility in single 3.3 V or 5 V systems where internal nodes may approach the rails. Validate output loading, noise, and stability in the intended feedback topology, and use short traces with a solid ground return to avoid introducing analog-path errors.
おすすめ
Voltage Level Conditioning
The TS912ID's rail-to-rail input and output behavior is useful when a sensor or logic-facing node operates close to the available supply voltage. In a 3.3 V or 5 V system, one channel can buffer a source while the other provides gain or filtering. The device's broad 2.7 V to 16 V supply range allows the same amplifier family to address several rail levels. Output swing remains dependent on load and output-current conditions, so engineers should read the manufacturer limits before designing level thresholds for digital interoperability.
おすすめ
Industrial Control Signal Conditioning
TS912ID can condition low-level analog signals in industrial control modules where a dual amplifier provides independent buffer or amplification channels. Its rail-to-rail operation supports single-supply systems, and the 800 kHz bandwidth is appropriate for many process-control and diagnostic loops rather than extremely high-speed sampling. The wide supply ceiling of 16 V provides flexibility for protected industrial rails. Designers must still account for electromagnetic interference, transient protection, grounding, and component tolerances outside the IC; the device itself does not provide surge protection.
おすすめ
Data Acquisition Front End
TS912ID is suitable for analog conditioning ahead of a data-conversion system, particularly when two channels must be buffered or amplified at moderate bandwidth. The 800 kHz gain-bandwidth product and 1.3 V/us slew rate allow useful response above precision-amplifier levels, while rail-to-rail operation can reduce headroom loss. For an ADC interface, compare offset, bias current, noise, settling behavior, and output drive before final selection because those values are not established in the supplied excerpts. Place the amplifier close to the source and ADC reference ground to minimize added noise.

設計ノート
Confirm the actual supply rails and load requirements before assigning TS912ID to a circuit. The device supports 2.7 V to 16 V operation, including single or dual supplies, but the verified data does not establish output-current capability or quiescent current. Add local ceramic supply decoupling according to the manufacturer datasheet, keep the return current close to the device ground pin, and avoid long supply traces that share return paths with sensitive feedback nodes.
Implement the two amplifier channels with short input and feedback paths, and keep the feedback components close to the associated pins. A high-gain layout can become unstable when parasitic capacitance couples the output back to an input. Route the two channels to avoid sharing susceptible signal traces, use a continuous ground reference, and place bypass capacitors at the supply pins rather than at a remote power entry point.
Do not assume that rail-to-rail input and output labels guarantee exact rail-to-rail behavior under every load. Verify output swing versus load current, output impedance, input common-mode limits, and stability in the manufacturer datasheet. Also distinguish TS912ID from related suffix codes such as TS912AID and TS912AIT; ordering suffixes can change temperature range, grade, or other commercial attributes even when the amplifier function and 8-SOIC footprint remain similar.
