TS932ID - Dual 100 kHz Rail-to-Rail Op Amp | STMicroelectronics
N.º da peça: TS932ID ✓ AtivoTS932ID Visão geral
An operational amplifier, or op amp, is a high-gain analog building block used to amplify, buffer, compare, and filter signals. The TS93x family belongs to the amplifier IC hierarchy, where rail-to-rail output stages allow an output voltage to approach the supply rails. This capability makes the TS932ID suitable for battery-powered sensors, portable instrumentation, and low-voltage analog interfaces.
Key characteristics include a 100 kHz gain-bandwidth product, 0.05 V/µs slew rate, and typical supply-current consumption of 20 µA. The output can reach 2.9 Vpp when supplied from 3 V with a 100 kΩ load. The TS93x series also features CMOS inputs, ultra-low input bias current of approximately 1 pA, and ESD protection. These characteristics favor high-impedance sources and energy-limited systems rather than demanding high-speed or high-precision instrumentation.
The TS932ID is a dual amplifier, allowing two independent signal paths in one package. Its rail-to-rail output architecture simplifies signal conditioning near low supply voltages, while its micropower operation reduces the burden on batteries or harvested-energy supplies. The 100 kHz bandwidth is adequate for audio-frequency, sensing, and general-purpose feedback-control loops, but it is not intended for high-frequency filtering, video amplification, or communications waveform processing.
Typical applications include battery-operated sensor conditioning, low-current comparator or threshold functions, portable measurement modules, low-frequency active filters, analog sensor interfaces, and general-purpose buffering. In each case, the device provides two amplifier channels in a compact 8-pin SOIC while consuming approximately 20 µA under the stated family conditions.
Designers should verify output load, input common-mode range, output swing, noise, offset, stability, and operating-temperature limits against the manufacturer datasheet before release. Decoupling capacitors should be placed close to the supply pins, and feedback-network components should be selected with practical bias-current and leakage considerations.
This page consolidates the verified distributor information, manufacturer-family characteristics, package details, application guidance, and substitution limitations for TS932ID. It also distinguishes documented drop-in options from unsupported cross-package or functional substitutes so engineers can make a traceable replacement decision.

Aplicações típicas
TS932ID é adequado para 6 aplicaçãos: Battery-Powered Sensor Conditioning, Portable Industrial Measurement, Low-Frequency Active Filtering, Threshold and Comparator Functions, Low-Power Audio Buffering, IoT and Environmental Sensing.
Battery-Powered Sensor Conditioning
The TS932ID fits battery-powered sensor interfaces because it operates from 2.7 V to 10 V and typically consumes only about 20 µA while providing two amplifier channels in an 8-pin SOIC. Its 100 kHz gain-bandwidth product is suitable for slow sensor outputs, and the approximately 1 pA input bias current reduces loading on high-source-impedance transducers. A typical implementation places the sensor on the noninverting input and uses feedback resistors for gain. Designers should verify the input common-mode range against the sensor’s operating span and check offset and noise limits before production.
Recomendado
Portable Industrial Measurement
The TS932ID is appropriate for portable industrial measurement modules that must balance channel count, low supply demand, and accurate low-frequency signal handling. Two independent amplifiers can condition a sensor and a reference or monitor an input and output signal within one 8-pin SOIC. Its 100 kHz bandwidth supports measurement loops that do not require wide-band response, while the 0.05 V/µs slew rate avoids the behavior of a general-purpose high-speed amplifier. Designers should confirm noise, offset, and common-mode specifications in the manufacturer datasheet for the required accuracy class.
Recomendado
Low-Frequency Active Filtering
The TS932ID can implement first-order or modest-bandwidth active filters in low-voltage sensor and audio control circuits. Its 100 kHz gain-bandwidth product provides more closed-loop bandwidth than required for many low-frequency filters, while approximately 20 µA typical consumption suits portable systems. The rail-to-rail output stage is useful when filter signals operate near the available supply range. Component selection should include the amplifier’s actual output swing, noise, and stability behavior; the verified 2.9 Vpp result at 3 V and 100 kΩ provides a useful initial limit.
Recomendado
Threshold and Comparator Functions
The TS932ID can be used as an open-loop comparator or as the active element in a threshold-detection circuit where its rail-to-rail output and low supply current are valuable. The dual configuration permits one channel to establish a threshold while the other performs signal conditioning or drives an indication path. Its 100 kHz bandwidth is ample for slow thresholds but does not guarantee low propagation delay for fast events. Engineers should review input common-mode limits, output saturation behavior, and supply compatibility in the STMicroelectronics datasheet before fixing the circuit topology.
Recomendado
Low-Power Audio Buffering
The TS932ID is suitable for buffering modest audio-band or control signals in portable equipment when low quiescent current is more important than wide bandwidth. Its rail-to-rail output can reduce clipping near low supply rails, and the 100 kHz gain-bandwidth product covers a substantial portion of the audio range. The 0.05 V/µs slew rate may limit large-signal swing at higher frequencies, so it is better suited to microphone buffers, headset interfaces, and low-level audio conditioning than to high-fidelity line-output stages. Verify noise and output-load limits before selecting it.
Recomendado
IoT and Environmental Sensing
The TS932ID fits IoT and environmental sensing nodes where multiple low-frequency analog channels must be conditioned from a limited power budget. Its dual topology can support an input amplifier and a feedback or monitoring channel, while 2.7 V minimum supply operation aligns with efficient low-voltage rails. The approximately 1 pA input bias current is advantageous for resistive sensors and leakage-sensitive front ends. Practical implementations still require careful grounding, source-impedance analysis, input filtering, and verification of the common-mode range under the sensor’s minimum and maximum operating conditions.

Notas de projeto
Place the supply bypass capacitor immediately between the positive supply and ground pins, with the ground connection following the shortest practical return path. Keep the input, feedback, and output traces compact to reduce parasitic pickup in the high-impedance CMOS-input circuit. Use a continuous ground reference beneath the circuit rather than relying on a fragmented plane, and follow the verified SOIC-8 land pattern and manufacturer assembly guidance.
Do not assume that rail-to-rail output automatically means the input common-mode range covers both supply rails. The verified data confirms rail-to-rail output behavior but does not provide a TS932ID input common-mode specification. Likewise, the reported 2.9 Vpp swing was measured at 3 V with a 100 kΩ load, so a heavier load or a different supply may reduce usable swing. Verify these limits before biasing inputs or outputs near the rails.
Calculate the amplifier’s own supply dissipation from the selected supply voltage and total supply current, but also account for output current delivered to the load. Estimated: at 3.3 V and 20 µA, the IC supply-power contribution is approximately 66 µW, before load-current and temperature effects. This simple estimate does not replace the datasheet limits for total power, output swing, and package temperature rise.
For high-impedance sources, minimize leakage from board contamination, long traces, and adjacent switching nodes. Keep the summing node and high-impedance input away from long exposed copper where possible, and consider guarding according to the application’s leakage requirements. The approximately 1 pA input bias current is a family characteristic, while actual leakage also depends on temperature, board materials, and protection devices.
Informações de conformidade
The supplied verified results do not contain explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements for TS932ID. These fields therefore remain unknown rather than being inferred from the manufacturer name or package type.
