TS512ID - 3 MHz Precision Dual Op Amp | STMicroelectronics
Teilenummer: TS512ID ✓ AktivTS512ID Übersicht
An operational amplifier is an analog integrated circuit that uses very high open-loop gain to amplify the difference between its inverting and non-inverting inputs. Precision operational amplifiers are a subtype of voltage-feedback amplifiers characterized by low offset voltage, low distortion, low noise, and stable operation with feedback. The dual-amplifier configuration places two amplifiers in one package, reducing board area and simplifying paired signal-processing circuits.
The TS512 family provides a 3 MHz gain-bandwidth product, low input offset voltage of 500 µV maximum, low power consumption, short-circuit protection, low distortion, low noise, high channel separation, and internal ESD protection. According to the STMicroelectronics family datasheet, the minimum slew rate is 0.8 V/µs for TS512 and TS512A. The related TS512B has a guaranteed higher minimum slew rate of 1.072 V/µs.
The TS512 family uses internal frequency and phase compensation to support stable operation in voltage-follower configurations. This is useful in application circuits where one amplifier buffers a source and the other performs gain or filtering. Its dual supply range is ±1.5 V to ±15 V, while single-supply operation is supported from 3 V to 30 V, allowing use in both conventional analog circuits and higher-voltage industrial interfaces.
Typical uses include sensor-signal conditioning, low-level instrumentation, active filtering, audio preamplification, and general analog signal processing. The dual channel can implement matched buffer, gain, summing, or differential stages. Because offset voltage influences accuracy near the zero-voltage operating point, input-source resistance and bias-current compensation should be evaluated carefully.
PCB layout should keep input and feedback paths short and place input compensation or filtering components close to the relevant amplifier pins. Both channels should share stable supply decoupling, while avoiding current paths through analog ground that carry output or digital return current. The SOIC package is suitable for conventional surface-mount assembly and conventional thermal design at low to moderate output current.

Typische Anwendungen
TS512ID ist geeignet für 6 Anwendungs: Low-Level Sensor Signal Conditioning, Precision Active Filtering, Audio Preamplification, Industrial Instrumentation Buffering, Data Acquisition Input Conditioning, Voltage Reference and Feedback Conditioning.
Low-Level Sensor Signal Conditioning
The TS512ID is appropriate for conditioning weak sensor signals because its two precision amplifier channels can be assigned to separate stages while sharing an 8-pin SOIC footprint. Its documented 3 MHz gain-bandwidth product provides useful bandwidth for many general-purpose sensor interfaces, while the 500 µV maximum input offset voltage helps control error near the zero-input condition. A typical implementation places one channel in a non-inverting gain stage and the other in an active filter or buffer. According to the STMicroelectronics TS512 family datasheet summary, low distortion, low noise, high channel separation, and short-circuit protection support this use, although sensor-specific validation must include input bias current, common-mode range, output swing, and operating temperature.
Empfohlen
Precision Active Filtering
The TS512ID can implement active-filter stages where the 3 MHz gain-bandwidth product and internal frequency and phase compensation provide a practical starting point for closed-loop design. Its two channels permit a second-order active-filter topology, a buffered summing stage, or a cascaded filter without requiring two separate packages. The documented 0.8 V/µs minimum slew rate should be checked against the filter's largest expected signal amplitude and highest operating frequency because slew-limited full-power bandwidth can be lower than the small-signal gain-bandwidth product. According to the STMicroelectronics family datasheet summary, the TS512ID also offers low distortion and high channel separation, both of which are useful when two channels must process related signals without introducing excessive crosstalk.
Empfohlen
Audio Preamplification
The TS512ID can serve in low-level audio preamplification and balanced input stages because its documented 500 µV maximum input offset voltage, low-noise feature set, and low distortion support precision small-signal work. Its dual-channel construction allows one amplifier to precede a balanced source while the other handles another polarity or a subsequent gain stage. The internal compensation supports voltage-follower configurations, which can simplify impedance conversion around audio sources. According to the STMicroelectronics TS512 family datasheet summary, short-circuit protection and low power consumption are also provided. Engineers should still verify the exact noise spectrum, output-current capability, output swing, and stability with the selected gain and load before using the device in a finished audio path.
Empfohlen
Industrial Instrumentation Buffering
The TS512ID is suitable for instrumentation buffering where sensor or transducer outputs must drive a following measurement stage. Its two channels can be used as independent input buffers, reducing component count while maintaining a 3 MHz gain-bandwidth product for signal bandwidth. The maximum 500 µV input offset voltage is important when the measured quantity is small, and the documented high channel separation can help when the two channels carry related measurements. According to the STMicroelectronics family datasheet summary, the device supports operation from 3 V to 30 V on a single supply or from ±1.5 V to ±15 V on dual supplies. Deployment in an industrial enclosure should also account for temperature grade, isolation barriers, grounding, and transient protection rather than relying only on the amplifier specifications.
Empfohlen
Data Acquisition Input Conditioning
The TS512ID can condition inputs in a data-acquisition system by providing two independently configured amplifiers in one 8-pin SOIC package. A practical circuit may use one channel as a unity-gain input buffer and the other as a gain stage feeding an ADC driver, while the 3 MHz gain-bandwidth product accommodates many moderate-bandwidth measurement paths. Low offset, low distortion, low noise, and high channel separation are listed by the STMicroelectronics family datasheet as key characteristics of the TS512 series. For acquisition use, the complete input-referred error budget should include offset voltage, input bias current, noise density, common-mode error, and reference accuracy. Sampling-system designers should also verify settling behavior for the selected gain, channel bandwidth, and acquisition period.
Empfohlen
Voltage Reference and Feedback Conditioning
The TS512ID can be used in feedback networks, reference-buffer interfaces, and precision current-loop circuits when two coordinated amplifier channels are advantageous. Its 500 µV maximum input offset voltage and 3 MHz gain-bandwidth product permit accurate signal amplification around a low-level reference, while the internal compensation supports unity-gain voltage-follower use. According to the STMicroelectronics TS512 family datasheet summary, the device also provides low power consumption and short-circuit protection. In reference applications, the offset-null pins offer an adjustment path, but their use should be deliberate: excessive range can introduce additional noise or drift. The complete design should verify reference stability, resistor matching, input bias current, output loading, and the temperature coefficient of any external adjustment network.

Wichtigste Unterscheidungsmerkmale
- Two precision amplifiers in one 8-pin SOIC (vs. TS512AIDT)
- Documented precision offset limit (vs. TS512IYDT)
- Clearer slew-rate trade-off than TS512B (vs. TS512B)
Designhinweise
Route each amplifier's inverting input and feedback components directly to pins 2 and 7, and keep the non-inverting inputs at pins 3 and 6 away from high-current supply and digital return paths. Place the offset-null network, when used, close to pins 1 and 5. According to the STMicroelectronics TS512 family documentation, internal compensation supports voltage-follower configurations, but PCB capacitance and feedback-loop geometry still affect stability and noise behavior.
Do not equate the 3 MHz gain-bandwidth product with a guaranteed 3 MHz usable closed-loop bandwidth at every gain. Noise gain, slew rate, load capacitance, and loop gain determine actual response. The family datasheet states a 0.8 V/µs minimum slew rate for TS512 and TS512A, so large-signal operation should be checked with the required peak-to-peak voltage and frequency. TS512B provides 1.072 V/µs, or 34% more minimum slew rate, when extra slew margin is needed.
Decouple each supply rail near pins 4 and 8 and provide a low-impedance return path to the source of the analog supply. The TS512ID supports 3 V to 30 V single-supply operation and ±1.5 V to ±15 V dual-supply operation. Avoid relying on the SOIC package to resolve supply transients or ground bounce generated by external circuitry. Validate the completed board for supply ripple coupling into the output, because that effect is not represented by the 3 MHz small-signal gain-bandwidth specification.
