TS954ID - Quad 3MHz R-to-R Op Amp | STMicroelectronics
MPN： TS954ID ✓ 啟用中TS954ID 概覽
An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its non-inverting and inverting inputs. A rail-to-rail output amplifier can approach the supply rails at its output, making it useful when the available signal range is small. The TS954 belongs to the amplifier IC hierarchy, where operational amplifiers are used for signal conditioning, buffering, active filtering, comparisons, and analog sensor interfaces.
The TS954 family provides four amplifiers per package, a 3 MHz gain-bandwidth product, and a 1 V/µs slew rate. Its input bias current is 35 nA, while the listed supply current is 950 µA per channel. These characteristics make it suitable for general-purpose signal conditioning operating from 2.7 V to 12 V, including low-voltage analog systems and battery-powered equipment.
The device uses a BiCMOS input architecture combining bipolar and CMOS process characteristics. Its rail-to-rail output stage allows useful output swing near the supply limits, while the low 35 nA input bias current reduces current errors when driving high-impedance sources. The 3 MHz bandwidth is adequate for audio-frequency and general instrumentation tasks, whereas applications requiring substantially faster closed-loop settling should use a higher-bandwidth amplifier.
Typical uses include low-level sensor amplification, active analog filters, audio signal conditioning, instrumentation, and four-channel buffering. The SOIC-14 package permits conventional surface-mount assembly and provides one amplifier per two package pins. Its quad configuration can also reduce board area compared with four separate single or dual amplifier packages when all four channels are required.
Designers should verify the required output swing, load impedance, input common-mode range, noise performance, and stability against the manufacturer datasheet before finalizing a circuit. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs should be biased according to the manufacturer recommendations so that input and output stages remain in their intended operating regions.
This page consolidates verified manufacturer and distributor information for the TS954ID, including the 3 MHz bandwidth, 1 V/µs slew rate, 2.7 V to 12 V supply range, 14-pin SOIC format, sourcing links, and the engineering trade-offs that distinguish a low-power quad amplifier from faster or more specialized alternatives.

典型應用
TS954ID 適用於 6 應用s: Low-Voltage Sensor Signal Conditioning, Portable Battery-Powered Analog Systems, Audio-Frequency Active Filtering, General-Purpose Instrumentation Buffering, Interface and Data-Acquisition Conditioning, Industrial Control and Monitoring.
Low-Voltage Sensor Signal Conditioning
The TS954ID fits low-level sensor amplification because its 2.7 V to 12 V supply range covers 3 V and 5 V systems, while its 35 nA input bias current limits loading on high-impedance sensing elements. Four amplifiers can provide excitation-adjacent buffering, gain stages, or active filtering without requiring four separate packages. The 3 MHz gain-bandwidth product and 1 V/µs slew rate are adequate for many general-purpose instrumentation signals, although sensor bandwidth, common-mode limits, and required settling should be checked before the gain is fixed.
推薦
Portable Battery-Powered Analog Systems
The TS954ID is suitable for portable equipment operating from a 3 V battery rail because STMicroelectronics specifies the family for 3 V and 5 V operation. Its listed 950 µA supply current per channel provides a meaningful low-power consideration when four channels are active, and the 14-pin SOIC reduces the footprint compared with four separate amplifier packages. Designers should still account for regulator efficiency, quiescent current, output loading, and any need to disable unused channels when calculating battery life.
推薦
Audio-Frequency Active Filtering
The TS954ID can implement active low-pass, high-pass, or band-pass stages in audio-frequency and control-signal paths. Its 3 MHz gain-bandwidth product gives useful closed-loop bandwidth for common low-frequency filters, while the 1 V/µs slew rate supports moderate-amplitude signals. The rail-to-rail output is valuable in compact 3 V or 5 V systems. Filter design must include noise gain, gain-bandwidth derating, output load, and stability checks rather than relying only on the nominal 3 MHz bandwidth.
推薦
General-Purpose Instrumentation Buffering
The TS954ID is applicable to instrumentation buffers because it provides four rail-to-rail amplifiers with low 35 nA input bias current and operation from 2.7 V to 12 V. These characteristics help preserve signals from medium- to high-impedance sensors and reduce loading errors. The 3 MHz bandwidth is suitable for many general measurement channels, but instrumentation accuracy also depends on input offset, input voltage noise, common-mode rejection, and drift, which must be obtained from the complete manufacturer datasheet for the selected operating conditions.
推薦
Interface and Data-Acquisition Conditioning
Four TS954ID channels can condition inputs entering an analog-to-digital converter by providing gain, offset adjustment, buffering, or active filtering before sampling. The 1 V/µs slew rate and 3 MHz bandwidth provide useful dynamic performance for many low- and moderate-frequency acquisition channels. The circuit must be checked for ADC input-range compatibility, acquisition time, settling to the required bit accuracy, source impedance, and the TS954ID output-swing limits; nominal bandwidth alone does not guarantee converter settling performance.
推薦
Industrial Control and Monitoring
The TS954ID fits industrial monitoring circuits that require four general-purpose analog channels on a 2.7 V to 12 V supply. It can amplify sensor outputs, interface control signals, and implement active filtering within a 14-pin SOIC package. Rail-to-rail output helps maximize signal range in low-voltage control systems, while the low 950 µA per-channel supply current listed in the supplied data supports power-conscious designs. Industrial qualification, noise immunity, temperature range, and EMC performance require separate verification because they are not specified in the supplied extracts.

主要差異化特點

- Low 35 nA input bias current (對比TS924ID)

設計說明
Design the supply network for the verified 2.7 V to 12 V operating range, with particular attention to the 3 V and 5 V conditions for which STMicroelectronics specifies the family. The listed supply current is 950 µA per channel, so four active channels can materially affect a low-power budget. Place the supply bypass capacitor close to the package and follow the manufacturer’s recommended decoupling network and load-current limits. Verify regulator headroom because a linear amplifier cannot regulate its input supply.
Keep analog input and output routing short and away from high-current switching nodes. Place input and output decoupling components near the relevant pins rather than distributing them around the board, and provide a quiet ground return for the amplifier. Because the exact pin numbering was not present in the supplied verified extracts, engineers must cross-check the official package drawing before assigning nets or making a board-layout change.
Do not assume that the nominal 3 MHz gain-bandwidth product remains available at every closed-loop gain. Higher noise gain reduces usable bandwidth and can affect stability, especially with capacitive loading. Also verify the output swing, input common-mode range, output-current capability, and noise behavior for the actual load. Rail-to-rail output does not mean the output can reach both supply rails under every load condition.
合規資訊
The supplied verified extracts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. The TS954ID is a general-purpose analog IC, so AEC-Q100 qualification is treated as not applicable unless a qualified ordering variant is specified.
