TS924ID - Quad Rail-to-Rail Op Amp | STMicroelectronics
N.º de pieza: TS924ID ✓ ActivoTS924ID Descripción general
An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its non-inverting and inverting inputs. A quad package contains four independent amplifier sections, allowing one TS924ID to implement four amplifier channels in a single 14-pin package. Rail-to-rail input and output operation helps preserve signal range in low-voltage systems where conventional amplifier stages may approach their supply limits.
Key features include four amplifier circuits, rail-to-rail operation, an 80 mA cited output-current capability, 80 dB common-mode rejection ratio, and a maximum input bias current of 0.1 µA. The TS924 family is described as a low-noise, low-distortion BiCMOS design. Its low bias current is particularly useful in high-impedance sensing paths, while the rail-to-rail characteristics support compact, low-voltage equipment.
The bipolar input stage and CMOS output stage form the BiCMOS architecture used in the TS924 family. Input bias current, common-mode rejection ratio, offset voltage, output-current capability, noise, and distortion are the principal parameters to check when comparing it with other quad low-voltage operational amplifiers. The verified TS924ID information cites a maximum offset of 5000 µV, a maximum bias current of 0.1 µA, and an 80 mA output-current feature.
Typical uses include low-voltage audio signal conditioning, portable and battery-operated equipment, current or voltage sensing interfaces, active filtering, and general analog buffers. Four amplifiers in one package can reduce board area when a design needs several channels. Applications requiring wider supply voltage, lower offset, lower noise, or different logic levels should verify those requirements against the complete manufacturer datasheet before production use.
Designers should provide adequate input and output bypassing, verify stable operation with the intended load and feedback network, and confirm that the amplifier input common-mode range includes the full signal swing. Because the output-current figure is a headline feature rather than a complete load-capability specification, cable, headphone, and capacitive-load applications require careful review of the datasheet's output-stage limits.
This product page consolidates verified distributor availability, pricing, environmental information, same-package alternatives, and practical selection guidance. It also distinguishes documented TS924ID facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers narrow a replacement without making an unverified electrical assumption.

Aplicaciones típicas
TS924ID es adecuado para 6 aplicacións: Low-Voltage Audio Signal Conditioning, Portable Battery-Powered Instrumentation, Current-Sense Amplifier Interface, Active Filter and Analog Control, Industrial Interface Signal Buffering, Low-Power Sensor Node Conditioning.
Low-Voltage Audio Signal Conditioning
The TS924ID fits low-voltage audio signal-conditioning blocks because it combines four rail-to-rail amplifier channels, operation optimized for 3 V and 5 V, and an 80 mA cited output-current capability. According to the STMicroelectronics family information, the TS924 is characterized for low noise and low distortion, making it suitable for preamplifier, mixer, and buffering stages in compact audio systems. Its 14-SO package also reduces the number of packages required when four amplifier channels are needed. Designers should still verify the required output swing, load stability, channel-to-channel matching, and distortion limits in the complete datasheet before driving headphones, speakers, or other reactive loads.
Recomendado
Portable Battery-Powered Instrumentation
TS924ID is suitable for portable instrumentation powered from low-voltage rails because the device is optimized for 3 V and 5 V operation and provides rail-to-rail amplifier channels. Its maximum input bias current of 0.1 µA is particularly relevant when the input source presents a high impedance, while the 80 dB CMRR helps reject common-mode disturbances in compact measurement systems. Four independent channels can condition sensor, reference, and feedback signals without requiring four separate packages. According to the verified manufacturer-family information, the device also offers low noise and low distortion, although an engineer must confirm the exact noise, offset, and bias-current conditions against the application requirements.
Recomendado
Current-Sense Amplifier Interface
The TS924ID can provide the gain and common-mode conditioning stage for a low-side or high-side current-sense amplifier in a 3 V or 5 V system. Its 0.1 µA maximum bias current helps reduce bias error when paired with a high-impedance shunt or instrumentation network, and the 80 dB CMRR supports rejection of common-mode voltage present around the measurement node. The 80 mA output-current capability is useful when driving a modest external load or ADC input stage. According to the manufacturer family data, the amplifier is intended for low-noise, low-distortion operation; the design must still account for input offset, resistor tolerance, gain error, and the ADC input range.
Recomendado
Active Filter and Analog Control
TS924ID supports active-filter and analog-control implementations that require several amplifier stages on a low-voltage board. Four rail-to-rail channels provide flexible topology options for low-pass, high-pass, or feedback-control loops, while operation optimized for 3 V and 5 V suits portable and industrial-control equipment. According to the STMicroelectronics family description, low noise and low distortion help preserve signal integrity in feedback networks. Because the verified material does not provide gain-bandwidth, slew-rate, output-capacitance, or recommended-filter-component values, each stage should be simulated against the actual source impedance, load, frequency, and stability requirements before implementation.
Recomendado
Industrial Interface Signal Buffering
The TS924ID can buffer low-level signals at an industrial interface boundary where a 3 V or 5 V analog domain requires rail-to-rail operation. Four channels can handle several sensor or control signals, while the 80 dB CMRR helps reduce interference coupled into high-impedance inputs. Its 80 mA output-current rating provides useful drive capability for downstream circuitry, subject to the complete output-stage limits in the STMicroelectronics datasheet. According to the verified family information, the low-noise and low-distortion characteristics make the device relevant to precision conditioning. The final design should include protection, input filtering, grounding, and checks for common-mode range and industrial temperature requirements.
Recomendado
Low-Power Sensor Node Conditioning
TS924ID is appropriate for front-end conditioning in a compact sensor node that operates from a 3 V or 5 V rail. Four rail-to-rail amplifier channels can condition multiple sensor outputs, and the maximum input bias current of 0.1 µA helps limit loading errors from high-impedance sensors. The 80 mA output-current feature offers more drive capability than a conventional low-power amplifier in many cases, while the -40 °C to +125 °C listed operating range supports designs intended for extended environmental conditions. According to the STMicroelectronics family information, low noise and low distortion are available; engineers should still verify the quiescent current and supply-current limits before selecting it for a battery-dominated design.

Notas de diseño
Do not treat the headline 80 mA output-current rating as permission to drive any load continuously. The verified material does not specify output swing versus load current, allowable output capacitance, or short-circuit behavior. Verify those limits in the STMicroelectronics datasheet, start with a conservative load, and confirm stability with the actual cable, headphone, sensor, or feedback network. The 3 V and 5 V optimization also requires checking absolute maximum and minimum supply limits for the selected variant.
Place input and output bypassing capacitors close to their associated supply and ground pins, and keep the exposed return path short. Because the TS924ID contains four amplifier channels, trace each channel's input and feedback components close to its assigned amplifier pins to reduce parasitic pickup and feedback-loop instability. Avoid routing output currents through input-reference ground paths. The verified source does not prescribe exact capacitor values, so use the manufacturer application circuit and stability guidance for final component selection.
Confirm that the signal can remain inside the amplifier's input common-mode range over the complete supply voltage, output swing, and process variation. Rail-to-rail input and output wording does not eliminate the need to check common-mode behavior near either rail. For high-impedance sources, account for the verified maximum bias current of 0.1 µA, source impedance, PCB leakage, and guard-ring layout. These checks are particularly important in low-voltage instrumentation where the signal occupies much of the available dynamic range.
