TS952ID - Dual 3MHz Rail-to-Rail Op Amp | STMicroelectronics
MPN: TS952ID ✓ ActiveTS952ID Overview
An operational amplifier, or op amp, is a high-gain analog building block used in amplification, buffering, filtering, sensing, and feedback-control circuits. The TS952 belongs to the rail-to-rail op-amp category within the broader amplifier IC and signal-chain hierarchy. Rail-to-rail input and output behavior allows signals near either supply rail to be processed with less conventional headroom loss than a fixed-input amplifier.
The TS952ID provides two amplifier circuits, a 3 MHz bandwidth, and a 1 V/us slew rate. According to the STMicroelectronics TS952 product-page data, the device is optimized for 3 V and 5 V operation. Other identified features include an 80 dB supply-voltage rejection ratio, 2 kV ESD protection, and low-power operation. These characteristics make the part applicable to low-voltage sensor conditioning, portable instrumentation, audio input stages, and general-purpose analog signal processing.
The BiCMOS architecture combines bipolar input-stage behavior with CMOS output circuitry and is intended to balance low-voltage operation, amplifier performance, and power efficiency. Because the TS952 is a dual device, two independent amplifier channels can share one package. The 8-pin SOIC outline also supports conventional surface-mount assembly, although final stability, bandwidth, and output-current behavior must be evaluated at the intended supply voltage and load.
Typical uses include battery-powered sensor interfaces, buffered analog inputs, portable measurement systems, audio preamplification, and low-voltage control loops. At 3 V, the device is aligned with compact battery-operated systems; at 5 V, it provides additional signal range for industrial and consumer analog circuits. The 3 MHz bandwidth is sufficient for many general-purpose conditioning stages but is not intended for high-speed video or precision wideband instrumentation without further analysis.
When designing around the TS952ID, verify input and output common-mode limits, output swing, load capability, noise, offset, and stability for the selected supply voltage. Decoupling capacitors should be placed close to the supply pins, and sensitive input traces should remain short and away from switching nodes. Feedback components should follow the manufacturer recommendations because gain-bandwidth, input capacitance, and capacitive loading can affect closed-loop behavior.
This product record combines the verified STMicroelectronics family description, distributor package information, operating range, bandwidth, slew rate, rejection, and ESD information with practical selection guidance. It also distinguishes verified facts from specifications that still require confirmation from the complete manufacturer datasheet, avoiding unsupported claims about electrical limits or replacement parts.

Typical Applications
TS952ID is suitable for 6 applications: Low-Voltage Sensor Signal Conditioning, Portable Battery-Powered Instrumentation, Audio Input Pre-Amplification, Active Filtering and Analog Control, Industrial 5 V Control Systems, General-Purpose Analog Buffering.
Low-Voltage Sensor Signal Conditioning
The TS952ID is suitable for conditioning sensor outputs from 3 V and 5 V systems because its input and output stages are rail-to-rail. A dual configuration can amplify one sensor channel while the second channel provides buffering, level shifting, or active filtering. Its 3 MHz gain-bandwidth product and 1 V/us slew rate provide adequate bandwidth for many low-frequency industrial and portable measurements. The amplifier should be configured with suitable feedback and output loading, and the complete datasheet should be checked for offset, noise, common-mode behavior, and stability under the selected gain.
Recommended
Portable Battery-Powered Instrumentation
The TS952ID fits portable measurement equipment powered from a 3 V rail because the family is optimized for 3 V operation and accepts supplies from 2.7 V to 12 V. Rail-to-rail input behavior helps maximize the usable range of low-amplitude sensor signals, while the dual circuit provides two channels in one 8-pin SOIC. The low-power BiCMOS implementation is useful for reducing the overall footprint of portable analog front ends. Battery life still depends on the complete system load, and quiescent current plus shutdown behavior should be confirmed from the full manufacturer documentation.
Recommended
Audio Input Pre-Amplification
The TS952ID can serve as a dual audio input pre-amplifier in low-voltage equipment because both the input and output can operate close to the supply rails. Its 3 MHz bandwidth is substantially wider than most audio-band signals, while the 1 V/us slew rate allows the output to follow moderate transient content. One channel may handle a left audio input and the other a right input, or the second channel may provide gain or filtering. Input biasing, output loading, distortion, noise, and stability with cable capacitance require evaluation before using the device with external audio sources.
Recommended
Active Filtering and Analog Control
The TS952ID can implement active filters and low-voltage analog control loops using its two amplifier channels. A 3 MHz gain-bandwidth product allows useful closed-loop bandwidth in many filter topologies, and rail-to-rail operation improves output range in control systems running from 3 V or 5 V. One channel may perform filtering while the other drives an actuator or buffer a reference. Component tolerances and op-amp gain-bandwidth behavior determine the achievable filter response, so simulation should include the selected resistor and capacitor values, expected load, and supply tolerance.
Recommended
Industrial 5 V Control Systems
The TS952ID is applicable to industrial control modules operating from a regulated 5 V rail because that voltage is within its stated 2.7 V to 12 V range and is one of the family's optimized operating points. Rail-to-rail inputs and outputs support control signals occupying much of the available supply range. Its two channels can reduce component count when the system requires amplification plus buffering. Industrial qualification requirements, input common-mode limits under transients, noise performance, and protection against industrial surges must be assessed separately from the basic amplifier specification.
Recommended
General-Purpose Analog Buffering
The TS952ID can buffer inputs into higher-impedance analog stages, particularly where the source signal is close to either supply rail. Rail-to-rail input and output behavior reduces headroom restrictions, while the 3 MHz bandwidth is more than adequate for many low-frequency buffers. The dual package allows two buffered channels or one signal channel plus a helper amplifier. Input bias current, offset voltage, output-current capability, capacitive-load stability, and settling behavior should be checked against the source impedance and downstream timing requirements.

Key Differentiators
- Dual-channel integration in an 8-pin SOIC (vs Single-amplifier alternatives)

- Family match with TS952IDT (vs TS952IDT)
Design Notes
Place the input and output bypass capacitors as close as practical to the corresponding SOIC-8 supply pins. Keep the feedback-resistor network close to the amplifier inputs and outputs to minimize parasitic capacitance and sensitivity to board contamination. The verified data identifies the 8-pin SOIC outline and 2.7 V to 12 V operating range, but it does not provide a recommended capacitor value; use the complete manufacturer datasheet and application guidance before finalizing the power network.
Do not assume that rail-to-rail input and output operation means every input, output, or load condition is unrestricted. Check common-mode limits, output swing, output-current capability, input-bias effects, and stable capacitive loading at the intended 3 V or 5 V supply. The supplied verified excerpts establish rail-to-rail behavior, 3 MHz bandwidth, and 1 V/us slew rate, but detailed limit values and stability guidance require the complete STMicroelectronics datasheet.
Keep high-impedance input traces short, guarded from switching-node and clock traces, and terminated according to the source impedance. If driving an ADC, sensor, or long cable, account for op-amp input capacitance, settling time, and the resulting filtering behavior. Because the TS952ID provides two amplifiers in one SOIC package, keep the two channels physically separated when one is sensitive and the other drives a fast or noisy signal.
Compliance Information
The supplied verified excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. The AEC-Q100 field is marked not_applicable because no automotive qualification is claimed for this general-purpose device.
