TS932IDT - Dual Micropower RRO Op Amp | STMicroelectronics
Teilenummer: TS932IDT ✓ AktivTS932IDT Übersicht
A rail-to-rail operational amplifier is an amplifier whose input and output voltage ranges can extend close to the supply rails. This capability helps preserve signal range in low-voltage systems where conventional amplifiers would clip signals near ground or the positive supply. The TS932 belongs to the operational-amplifier hierarchy, combining low quiescent consumption, CMOS input capability, and rail-to-rail operation in a compact SOIC-8 package.
The TS932IDT provides two amplifier circuits in one package. According to the STMicroelectronics manufacturer datasheet, the TS93x series can operate with voltages as low as 2.7 V and reaches a 2.9 Vpp output swing with a 100 kΩ load when supplied at 3 V. Typical consumption is only 20 uA, making the dual amplifier suitable for portable instrumentation and other systems where supply efficiency and signal headroom are important.
Its CMOS inputs support low-bias operation, while the 100 kHz gain-bandwidth product suits general-purpose low-frequency amplification rather than high-speed signal chains. The rail-to-rail output also improves usable output range near the supply limits. These characteristics make the device relevant to sensor interfaces, battery-powered measurement systems, audio control circuits, and low-power industrial electronics.
Typical uses include buffering sensor outputs, amplifying low-level analog signals, and providing two independent amplifier channels in one package. Designers should account for the 100 kHz bandwidth when choosing feedback resistors and gain settings. High-gain configurations also require attention to input offset, bias current, noise, and stability.
Use the TS932IDT when a dual amplifier, low quiescent current, and rail-to-rail operation are required in a compact SOIC-8 footprint. Confirm output loading, capacitive loads, supply range, and required bandwidth against the manufacturer datasheet before finalizing a precision or high-gain design.

Typische Anwendungen
TS932IDT ist geeignet für 6 Anwendungs: Battery-Powered Sensor Conditioning, Portable Measurement Instrumentation, Low-Power Audio Control Signal, Industrial Threshold Detection, IoT Edge Signal Conditioning, Battery Monitoring and Buffering.
Battery-Powered Sensor Conditioning
The TS932IDT fits low-power sensor interfaces because its CMOS inputs, 20 uA typical consumption, and operation from 2.7 V reduce the burden on an energy-limited supply. Its rail-to-rail output can preserve signal range in low-voltage systems. Two channels are available for amplification or active filtering without adding separate amplifier packages. According to the STMicroelectronics manufacturer datasheet, the 100 kHz gain-bandwidth product supports general-purpose conditioning, although sensor source impedance, offset, noise, and capacitive loading must be checked before selecting the gain.
Empfohlen
Portable Measurement Instrumentation
Portable measurement equipment benefits from the TS932IDT's 2.7 V minimum supply voltage and typical 20 uA consumption, allowing low-voltage analog channels to remain active without a high quiescent-current penalty. The dual SOIC-8 configuration provides two amplifier functions in one footprint. According to the STMicroelectronics manufacturer datasheet, the 100 kHz gain-bandwidth product is appropriate for many slowly varying measurement signals. Precision designs should still evaluate input offset, bias current, noise, leakage, and the output settling required by the measurement bandwidth.
Empfohlen
Low-Power Audio Control Signal
The TS932IDT can process low-level control signals in portable audio equipment where power consumption and output headroom are important. Its rail-to-rail output allows a 2.9 Vpp swing at a 3 V supply with a 100 kΩ load, reducing clipping near the supply rails. The 100 kHz bandwidth is suitable for many control and monitoring paths rather than high-fidelity audio signal chains. According to the STMicroelectronics manufacturer datasheet, 20 uA typical consumption supports battery-powered operation when the external load remains appropriately controlled.
Empfohlen
Industrial Threshold Detection
The TS932IDT can implement dual-channel threshold detection or comparator-like signal conditioning in compact industrial electronics. Its rail-to-rail output improves usable signal range at low supply voltages, while the 20 uA typical consumption supports remote or maintenance-powered nodes. According to the STMicroelectronics manufacturer datasheet, the device operates from 2.7 V and offers 100 kHz bandwidth. Care is required when driving long cables, high-capacitance inputs, or ADC front ends because external impedance and settling behavior can influence accuracy.
Empfohlen
IoT Edge Signal Conditioning
The TS932IDT is useful ahead of an ADC or communications device in an IoT sensor node because it offers two low-power amplifier channels in an 8-pin SOIC. The 20 uA typical consumption is valuable where the amplifier must remain active during long standby intervals, while rail-to-rail output improves headroom at a 3 V-class supply. According to the STMicroelectronics manufacturer datasheet, its 100 kHz bandwidth suits low-rate sensor signals. The design must ensure ADC acquisition time, source impedance, filtering, and output swing remain compatible.
Empfohlen
Battery Monitoring and Buffering
The TS932IDT can buffer battery or supply sensing nodes where low supply voltage and micropower operation are central concerns. One channel may amplify a divided battery voltage while the other handles a related current or threshold signal, reducing board area. According to the STMicroelectronics manufacturer datasheet, the device starts operating at 2.7 V and typically consumes 20 uA, with a 100 kHz gain-bandwidth product. Engineers should verify the battery chemistry's voltage range, input common-mode behavior, leakage effects, and accuracy requirements before using the amplifier for safety-critical measurements.

Wichtigste Unterscheidungsmerkmale
- Two amplifier channels in one compact package (vs. TS93x single-channel variants)
- Low-voltage rail-to-rail operation (vs. TS93x quad-channel variants)
- Micropower operation for portable systems (vs. General-purpose higher-bandwidth amplifiers)
Designhinweise
Design the power budget around both channels because a dual amplifier can consume more total current than the 20 uA typical per-amplifier figure. Confirm the actual supply voltage, output load, and operating state against the STMicroelectronics manufacturer datasheet. Use the Request a Quote form for current order and delivery information, and avoid estimating battery life from amplifier consumption alone because sensor, ADC, and interface loads may dominate.
Keep the 100 kHz gain-bandwidth product in perspective when selecting feedback resistors and closed-loop gain. According to the STMicroelectronics manufacturer datasheet, usable bandwidth decreases as noise gain increases. For a precision signal path, evaluate offset, bias current, noise, and settling at the actual signal frequency. Place high-frequency bypass capacitors close to the supply pins and keep sensitive input routing short to reduce added noise and pickup.
Do not assume that rail-to-rail operation eliminates output-loading restrictions or makes the amplifier suitable for every capacitive load. Check the output swing at the actual load current, keep the input common-mode voltage within its rated operating region, and observe the maximum total supply voltage of 10 V. Confirm the exact pin assignments in the manufacturer pinout before assigning the two amplifier channels on the PCB.
Place the bypass capacitor immediately between the supply and ground pins, and route the ground return directly to the device ground without narrow neckdowns. The 8-pin SOIC footprint allows a compact layout, but analog input and output traces should remain away from switching nodes and high-current return paths. If either input is connected to a remote or high-impedance source, add the protection and filtering required for leakage, ESD, and settling.
