TS924IN - Quad 4MHz Rail-to-Rail Op Amp | STMicroelectronics
MPN: TS924IN ✓ सक्रियTS924IN अवलोकन
An operational amplifier is a high-gain analog signal-conditioning IC used in the broader voltage-amplifier and analog IC hierarchy. The TS924IN combines four independent amplifiers in one package, allowing compact implementation of filters, amplifiers, comparators, instrumentation circuits, and signal-conditioning stages. Its rail-to-rail output design supports operation close to the supply rails, while its BiCMOS construction combines bipolar input characteristics with CMOS output stages.
The headline specifications are 4 MHz gain-bandwidth product, 1.3 V/us slew rate, and input offset voltage of 900 uV maximum. The TS924 family is fully specified for 3 V and 5 V supply operation, and the supplied operating-range information extends to 12 V. Its high output-current capability is particularly useful for driving low-impedance loads compared with many general-purpose op-amplifier choices.
Each channel can operate as an amplifier, comparator, or active-filter building block. The wide available bandwidth supports signal paths that need more gain-bandwidth than low-speed precision-oriented amplifiers, while the 1.3 V/us slew rate allows moderate-amplitude signals to transition without excessive distortion. Four integrated channels can reduce package count and simplify board layout in multi-channel measurement and control systems.
Typical uses include industrial sensor interfaces, low-voltage audio and communication circuits, active filters, data-acquisition front ends, process-control loops, and general-purpose analog signal conditioning. The 14-DIP format is especially useful when maintaining an existing through-hole design or avoiding a conversion to a surface-mount footprint. Input and output protection should still be considered because the verified data does not establish the maximum input or output voltage range.
The principal design consideration is the power relationship between supply voltage, output swing, load current, and dissipation. Because no thermal-resistance or absolute maximum-rating data was included in the verified results, those values must be confirmed in the manufacturer datasheet before production release. Decoupling capacitors should be placed close to the supply pins and return pins should follow a low-impedance layout.
This product record combines verified manufacturer and distributor information, package-specific replacement guidance, practical design considerations, and a parameter comparison that helps engineers distinguish true pin-compatible alternatives from merely functional substitutes. It supports component selection for legacy 14-DIP analog designs without treating incompatible package or performance variants as drop-in replacements.

TS924IN के लिए उपयुक्त है 6 अनुप्रयोगs: Industrial Sensor Signal Conditioning, Active Audio and Communication Filters, Data Acquisition Front Ends, Process Control Loops, Portable and Battery-Powered Analog Circuits, Legacy Through-Hole Amplifier Upgrade.
Industrial Sensor Signal Conditioning
The TS924IN fits four-channel industrial sensor conditioning because it combines four rail-to-rail amplifiers, a 4 MHz gain-bandwidth product, and a 1.3 V/us slew rate in one 14-DIP package. Each channel can amplify or filter a low-voltage sensor signal before conversion or control processing. Its low-voltage optimization for 3 V and 5 V supports compact embedded systems, while the 900 uV maximum input-offset voltage provides a useful baseline for general instrumentation. Designers should still verify sensor output range, common-mode limits, noise, and required accuracy. Because the verified information does not include input-noise density, bias current, or absolute maximum ratings, those parameters should be obtained from the manufacturer datasheet before selecting the device for precision bridge or thermocouple channels.

Active Audio and Communication Filters
The TS924IN is suitable for active filtering and communication-signal conditioning when a compact four-amplifier implementation is valuable. Its 4 MHz gain-bandwidth product supports moderate-bandwidth filter sections, while the 1.3 V/us slew rate reduces distortion when signals require faster transitions. Rail-to-rail output behavior can improve use of a 3 V or 5 V supply, subject to the exact output-swing limits. The 14-DIP footprint also makes the device convenient for legacy audio boards and educational or industrial analog-control designs. Component values and stability should be checked against the manufacturer's recommended operating region, especially for high-Q filters, where gain and phase margin can change with load and frequency.
अनुशंसित
Data Acquisition Front Ends
The TS924IN can provide four independent input-conditioning channels for a data-acquisition front end using its 4 MHz gain-bandwidth product and rail-to-rail outputs. A typical arrangement uses one channel per sensor or differential input, with external resistors setting gain and capacitors establishing filtering and anti-alias bandwidth. The 1.3 V/us slew rate helps preserve moderate-amplitude transient information, while the 900 uV maximum offset specification provides an initial error-budget reference. Engineers must still compare input bias current, noise, common-mode range, and ADC input range, none of which were quantified in the supplied search results. The DIP package is useful when maintaining or repairing a through-hole acquisition board rather than redesigning it around a surface-mount amplifier.
अनुशंसित
Process Control Loops
The TS924IN is appropriate for general process-control functions that require more than one amplifier in a compact through-hole implementation. Its four channels can support sensor amplifiers, error amplifiers, comparators, and output-buffer stages within a controller. Operation optimized for 3 V and 5 V suits low-voltage industrial control boards, and the high-output-current capability can drive stages that are beyond the comfortable range of many small-signal amplifiers. Design work should verify output swing, capacitive-load stability, and supply-current limits under the expected load. Any PID loop also requires an independent stability analysis of the amplifier, sensor, filter, and actuator; the TS924IN's 4 MHz bandwidth and 1.3 V/us slew rate provide useful bandwidth but do not by themselves determine loop response.

Portable and Battery-Powered Analog Circuits
The TS924IN can serve in portable or battery-powered measurement modules when the circuit operates from a 3 V or 5 V rail and requires several analog channels. Its four-channel integration can reduce the number of packages and board connections compared with four separate amplifiers. Although the available data does not quantify quiescent current, the operating-voltage optimization makes it a logical candidate for low-voltage system design. Engineers should compare battery life against the manufacturer-specified supply current and evaluate whether the 14-DIP package fits the mechanical constraints. Rail-to-rail output capability can be valuable near the supply limits, but the available search snippets do not define the precise input and output ranges, so those values must be confirmed before sizing the battery and analog front end.
अनुशंसित
Legacy Through-Hole Amplifier Upgrade
The TS924IN is especially useful for maintaining or updating a legacy 14-DIP analog board that benefits from a 4 MHz gain-bandwidth product and 1.3 V/us slew rate. Its through-hole format avoids forcing a mechanical and layout conversion when replacing an older quad general-purpose amplifier. Rail-to-rail output behavior may provide additional signal range in 3 V and 5 V systems, but the circuit's pin functions and common-mode requirements must be verified before fitting it to a board designed for another device. A practical upgrade should compare the old part's offset, bias current, noise, output swing, stability with capacitive loads, and absolute maximum ratings against the manufacturer datasheet. The TS924IN is therefore suitable for footprint-compatible legacy work, not an assumption of unconditional electrical interchangeability.

डिज़ाइन नोट्स
Place the TS924IN supply bypass capacitor immediately between the positive supply and ground pins, using the shortest possible traces. Follow the manufacturer datasheet for the required capacitance and ESR range. A solid ground plane reduces return-path impedance, while keeping the four amplifier channels physically separated from high-current switching nodes prevents output transients from coupling into sensitive inputs.
Route each op-amp channel as a compact loop containing its input, feedback, and output nodes. Short feedback traces reduce parasitic capacitance and the chance of oscillation. Avoid routing input traces beneath the DIP body, adjacent to output pins, or through noisy supply paths. If the output drives a capacitive or long cable load, verify stability from the manufacturer data and add the required isolation resistance or buffering.
Do not assume that a 14-DIP quad amplifier is pin-compatible solely because the package matches. Before replacing TS924IN, compare supply limits, input common-mode range, output swing, offset, bias current, noise, slew rate, stability, and absolute maximum ratings. The verified results do not quantify several of these limits, so use the current STMicroelectronics datasheet rather than relying on a distributor equivalence label or an informal cross-reference list.
Validate power dissipation from the actual supply voltage, output voltage, quiescent current, and load current using the manufacturer limits. The TS924IN is optimized for 3 V and 5 V operation, and the verified operating-range information extends to 12 V. Operation at the upper range generally requires a more complete thermal and output-current assessment, particularly when driving low-impedance loads at high output voltage.
