TS514IN - Quad Precision Op Amp | STMicroelectronics | DIP-14
N.º da peça: TS514IN ✓ AtivoTS514IN Visão geral
An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. A quad operational amplifier extends this architecture to four independent channels in one package, reducing board area and simplifying multi-channel designs. The TS514IN belongs to the broader operational-amplifier, analog-amplifier, signal-conditioning, and semiconductor hierarchy.
The TS514IN's compensated architecture is intended to support stable operation as a voltage follower despite its high gain-bandwidth product. Internal compensation simplifies circuit design when unity-gain stability is required, while short-circuit protection improves robustness in conventional analog signal paths. Low offset voltage supports precision-oriented instrumentation, and low noise and low distortion are useful for audio and measurement front ends.
Four channels make the device suitable for sensor signal conditioning, current-voltage conversion, active filtering, waveform shaping, instrumentation amplifiers, feedback networks, and general analog control loops. The 14-DIP package is appropriate for through-hole prototyping, educational systems, laboratory instruments, and industrial assemblies where a dual-inline footprint is preferred over a fine-pitch surface-mount package.
The principal design consideration is to verify the supply-voltage limits, input common-mode range, output swing, input bias current, noise density, and load-current behavior against the manufacturer datasheet before finalizing a new design. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs should be tied to a defined voltage within the input common-mode range.
This page consolidates the verified manufacturer and distributor information, package details, application guidance, technical limitations, and drop-in replacement analysis. It also identifies parameters that require confirmation from the complete TS514 datasheet rather than substituting unverified assumptions.

Aplicações típicas
TS514IN é adequado para 6 aplicaçãos: Sensor Signal Conditioning, Audio Preamplifier and Filter, Active Filter Design, Current-to-Voltage Conversion, Precision Voltage Buffering, Laboratory Instrumentation.
Sensor Signal Conditioning
The TS514IN is suitable for conditioning low-level sensor signals because its four compensated channels can each provide buffering or amplification without requiring four separate packages. The manufacturer identifies a maximum offset voltage of 500 uV, low noise, low distortion, and short-circuit protection as useful characteristics for instrumentation paths. Engineers can implement non-inverting or inverting conditioning stages, subject to the input bias current, common-mode range, and supply limits in the full datasheet. The stable voltage-follower capability is particularly useful when a sensor output must be isolated from the following ADC or measurement circuit. Board-level implementation should keep the amplifier close to the source, use a solid ground reference, and avoid long high-impedance traces that increase noise pickup.
Recomendado
Audio Preamplifier and Filter
The TS514IN can support audio preamplifier and active-filter stages because its manufacturer-listed features include low noise, low distortion, high channel separation, and internal phase compensation. Four channels allow multiple low-level stages to share one package, while the compensated design supports voltage-follower configurations where stable operation is required. Actual suitability depends on the required bandwidth, slew rate, output swing, and load impedance, which are not quantified in the supplied excerpts. In a practical audio board, the amplifier should be powered from adequately decoupled rails and grounded carefully to prevent hum and switching noise from entering the signal path.
Recomendado
Active Filter Design
The TS514IN's four channels and internal frequency and phase compensation make it a candidate for multi-stage active filters and frequency-response shaping. Each amplifier can implement a standard inverting, non-inverting, or voltage-follower building block, while low distortion helps preserve intended waveforms across the usable bandwidth. Component tolerances and amplifier stability remain critical, so the complete gain-bandwidth, slew-rate, output-current, and loading specifications should be obtained from the manufacturer datasheet before finalizing filter poles. The 14-DIP format also simplifies point-to-point construction in laboratory filters and educational instrumentation.
Recomendado
Current-to-Voltage Conversion
The TS514IN can be used in transimpedance and current-to-voltage conversion circuits where four sensing or control channels share a common analog front end. The 500 uV maximum offset voltage, low noise, and short-circuit protection support precise measurement, while internal compensation permits straightforward feedback layouts including voltage-follower use. Designers must verify input bias current because it can create an error when working with high source impedance, and the complete datasheet should be consulted for common-mode range and output-swing boundaries. Feedback and compensation components should be placed close to the relevant amplifier pins to minimize parasitic feedback and unstable behavior.
Recomendado
Precision Voltage Buffering
The TS514IN is explicitly intended to remain stable as a voltage follower despite its high gain-bandwidth product, making it appropriate for buffering a reference or low-impedance drive into a subsequent circuit. Four channels allow multiple reference buffers or auxiliary signal paths to be implemented in one 14-DIP package. The manufacturer-listed short-circuit protection and internal ESD protection add robustness, but they do not replace correct operating-limit checks. For best results, keep the feedback loop compact, use low-inductance routing, observe the output-load limits from the datasheet, and provide local supply bypassing to preserve stability under dynamic load.
Recomendado
Laboratory Instrumentation
The TS514IN fits laboratory instrumentation prototypes that require four general-purpose analog channels, low offset voltage, and stable voltage-follower operation. Possible uses include source buffering, programmable-gain stage control, sensor conditioning, and active feedback networks. The through-hole 14-DIP package is convenient for laboratory assembly and rework, while the four-channel integration reduces panel space and wiring complexity. Engineers should avoid inferring a particular measurement accuracy from the 500 uV offset limit alone; resistor errors, input bias current, noise, and common-mode restrictions can dominate the total error budget.

Notas de projeto
Place the supply-bypass capacitors directly adjacent to the V+ and V- pins and keep their ground returns short. The verified excerpts identify low power consumption but do not provide numerical quiescent current or recommended capacitance, so the manufacturer datasheet should determine the values. Check the maximum supply voltage and total supply current for the load before energizing the circuit.
Keep each amplifier's inverting-input feedback trace short and away from high-impedance input and clock lines. For sensitive measurement circuits, route the input directly to the relevant pin and maintain a continuous ground reference beneath the analog section. The compensated TS514 architecture supports voltage-follower use, but physical layout still affects noise, stability, and channel separation.
Do not assume the 500 uV maximum offset voltage is the complete error budget. Input bias current, resistor tolerance, input common-mode limits, output swing, load capability, and temperature can materially affect accuracy. Confirm all operating limits from the official TS514 datasheet for the exact TS514IN ordering code, especially in transimpedance, precision-divider, and near-rail output applications.
Informações de conformidade
The supplied manufacturer and distributor excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because the TS514IN is a general-purpose analog amplifier rather than an automotive-qualified device in the verified data.
