TS924IPT - Quad Rail-to-Rail Op Amp | STMicroelectronics
MPN: TS924IPT ✓ AktifTS924IPT Ringkasan
An operational amplifier is a voltage-gain building block used to amplify small signals, buffer voltage sources, compare analog levels, and drive external circuits. The TS924 belongs to the BiCMOS operational-amplifier family, combining bipolar input circuitry with CMOS output stages. Rail-to-rail operation allows the amplifier to process input and output signals near the limits of its supply voltage, making it useful when the usable signal range is narrow.
The four amplifiers in one package support space-efficient analog designs requiring multiple gain stages or buffered channels. Operation is optimized for both 3 V and 5 V systems, covering common low-voltage rails found in portable electronics, industrial controls, audio equipment, and embedded systems. Rail-to-rail output swing and high output-current capability also help the device accommodate heavier loads than a general low-power amplifier.
The TS924 family is characterized by low noise, low distortion, and low offset, supporting accurate amplification of low-level signals. These characteristics matter in audio paths where distortion limits perceived fidelity, in sensor interfaces where small voltage changes must be preserved, and in control systems where offset can shift a measurement or threshold. The quad configuration also reduces component count and simplifies board-space allocation.
Typical uses include headphone and line-level audio buffers, microphone preamplification, low-voltage sensor conditioning, active filtering, voltage followers, and low-level comparator functions. In each case, the four independent amplifier sections can implement parallel channels or several stages within the same subsystem. Designers should confirm output-current demand, load impedance, stability, and input/output common-mode limits against the manufacturer datasheet for the selected operating condition.
A key design consideration is power-supply decoupling and careful handling of capacitive loads. Place the input and output bypass capacitors close to their associated pins, keep sensitive input traces short, and account for the amplifier's behavior when driving resistive or capacitive loads. The datasheet pin description and recommended application circuit should guide the final layout.
This page combines the TS924 family's operating characteristics with application guidance, design cautions, and a structured comparison of identified drop-in candidates. It is intended to help engineers evaluate the TS924IPT for 3 V and 5 V analog systems before implementing the 14-pin TSSOP footprint on a PCB.

Aplikasi Biasa
TS924IPT patut untuk 6 aplikasis: Low-Voltage Audio Buffering, Portable Sensor Signal Conditioning, Industrial Active Filtering, Precision Voltage Buffering, Audio and Communications Interface, Embedded Control Signal Conditioning.
Low-Voltage Audio Buffering
The TS924IPT is well suited to audio buffering at 3 V or 5 V because its four rail-to-rail BiCMOS amplifier channels provide low noise, low distortion, and high output-current capability. Multiple channels can be assigned to source, volume, or headphone-driver stages, reducing board area compared with four separate packages. Place each amplifier in a voltage-follower configuration when the goal is impedance buffering, and keep the source impedance and load within the limits defined by the manufacturer datasheet. Rail-to-rail input and output operation helps retain useful signal range when the available headroom is limited.
Portable Sensor Signal Conditioning
The TS924IPT can condition low-level signals from battery-operated sensors because it combines four amplifier channels, rail-to-rail operation, low offset, and low noise in a 14-pin TSSOP package. A typical arrangement could amplify one sensor channel while using the other amplifiers for filtering, buffering, or reference conditioning. Optimization for 3 V and 5 V supplies supports common portable-system rails. The designer should select resistor values and feedback networks against the device’s gain-bandwidth and stability limits, and should check whether the sensor source impedance requires a biasing path.
Industrial Active Filtering
The quad TS924IPT is useful for compact active-filter and control blocks operating from 3 V or 5 V. Its four channels allow a two-stage filter, dual-channel filter, or mixer to share one package, while low noise and low distortion support accurate processing of small signals. Rail-to-rail output swing can improve utilization of the available supply voltage, and high output-current capability allows the amplifier to drive the next filtering stage more effectively. Component tolerances, loop gain, phase margin, and capacitive loading must be evaluated using the application information in the STMicroelectronics TS924 datasheet.
Precision Voltage Buffering
The TS924IPT can buffer high-impedance sources when its low-offset, low-noise characteristics are important to measurement accuracy. Four independent channels make it practical to implement a multi-sensor buffer, a voltage follower ahead of an ADC, or several gain stages around a shared analog subsystem. Its 3 V and 5 V optimization aligns with both portable instruments and embedded industrial controls. For each channel, verify input bias-current effects, output-voltage limits, load stability, and settling behavior under the intended signal bandwidth before using the device as a precision buffer.
Audio and Communications Interface
The TS924IPT fits interface and mixing stages that require rail-to-rail signal handling at low supply voltages. Low distortion supports signal integrity in audio paths, while low noise benefits communications front ends that process small amplitudes. The four channels can implement differential input buffering, active gain stages, or mixers within one package. Its high output-current capability provides additional drive margin when feeding the next stage, but the designer should still examine capacitive loading and output-current requirements. Keep routing short and maintain the decoupling arrangement recommended for the selected operating voltage.
Embedded Control Signal Conditioning
The TS924IPT can condition analog control signals around an embedded controller when four rail-to-rail amplifier channels are needed on a 3 V or 5 V rail. Typical uses include sensor amplifiers, threshold drivers, and voltage followers feeding a converter or comparator input. Low offset helps reduce systematic error, while the TSSOP-14 package conserves PCB area in compact control boards. Decoupling capacitors should be positioned close to the supply pins, sensitive input traces should remain away from switching nodes, and unused amplifier inputs should be configured according to the manufacturer’s recommendations.

Catatan Desain
Place the supply-bypass capacitors close to the amplifier’s supply and ground pins, following the manufacturer’s recommended values and layout. Keep each input node short and avoid routing high-impedance signals beside digital return currents. Because the TS924IPT contains four amplifier sections in one 14-pin TSSOP, crowded layouts can couple noise between channels even when the electrical schematic is correct.
Do not assume that every similarly named STMicroelectronics amplifier is pin-compatible. The TS924IPT, TS924AIPT, TS925IPT, and TS925AIPT share a relevant 14-pin TSSOP and 3 V to 5 V operating context, but phantom-ground behavior and variant details may differ. Compare the manufacturer pin table and application diagrams before substituting any part into an existing PCB.
For audio or sensor-conditioning applications, isolate sensitive input traces from the amplifier output and from switching-power circuitry. Use a continuous ground reference beneath the TSSOP where the layout permits it, and terminate unused amplifier channels according to the datasheet. This prevents an otherwise correct four-channel package from introducing crosstalk, offset drift, or unintended oscillation.
Verify stability with the actual source and load impedances before adding compensation or isolation components. Rail-to-rail input and output stages can handle signal levels close to the supply rails, but capacitive loading may affect transient response and output-current demand. Use the manufacturer’s characteristic curves and recommended driving arrangements to select resistive isolation, if needed.
Maklumat Kesediaan
The TS924 is a general-purpose operational amplifier rather than an automotive-qualified device. Specific RoHS, REACH, lead-free, halogen-free, and conflict-minerals declarations require confirmation from the manufacturer or current material-compliance documentation.
