TLV274ID - Quad 16V 3MHz RRO Op Amp | Texas Instruments
MPN: TLV274ID ✓ Hoạt độngTLV274ID Tóm tắt
An operational amplifier is an active analog component that uses high open-loop gain to amplify the difference between two input voltages. The TLV274 belongs to the operational-amplifier hierarchy and combines rail-to-rail output swing with a relatively high 3 MHz bandwidth. That balance is useful for signal conditioning, filtering, buffering, and general instrumentation where low supply current and usable high-frequency response matter.
Key characteristics include four independent amplifiers in one package, rail-to-rail output, 3 MHz bandwidth, 2.4 V/us slew rate, and 550 uA/channel supply current. The reported input-voltage noise density is 39 nV/sqrt(Hz), while input bias current reaches as low as 1 pA in the characterized operating range. These values support low-level signal work, although input offset voltage, input common-mode range, and output-current limits were not supplied in the verified data.
The TLV274ID is based on a rail-to-rail-output amplifier architecture rather than a rail-to-rail-input design. Designers must therefore verify that input signals remain inside the allowed common-mode region. Its 3 MHz bandwidth enables moderate-frequency feedback networks and sensing loops, but stability should be checked against output loading, capacitance, noise gain, and filter topology.
Typical uses include low-power sensor conditioning, audio and communication interfaces, current measurement, data acquisition, filtering, and embedded analog control. Placing four amplifiers in one SOIC can reduce package count, but adjacent channels may share supply and thermal conditions. Decoupling and grounding therefore remain important when driving successive signals.
Begin each supply rail with suitable local bypass capacitance and route high-current return paths away from sensitive analog inputs. Because the exact compensation recommendations and electrical limits are unavailable in the supplied source set, use the manufacturer datasheet for final gain, load, stability, and layout validation.
This page combines verified product facts, application guidance, procurement context, and a conservative comparison of documented family variants. Its added value is an engineering-focused explanation of where the TLV274ID fits without treating unavailable electrical limits as assumptions.

Ứng dụng tiêu biểu
TLV274ID phù hợp cho 6 Áp dụngs: Low-Power Sensor Conditioning, Battery-Powered Instrumentation, Data Acquisition Front End, Active Filtering, Industrial Control Interfaces, Communication Signal Buffering.
Low-Power Sensor Conditioning
The TLV274ID fits low-power sensor conditioning because each channel operates from a 2.4 V minimum supply with 550 uA nominal supply current, while 3 MHz bandwidth is ample for many moderate-speed feedback networks. Use one channel to amplify a sensor bridge or resistive divider and additional channels for filtering or level shifting within the confirmed input common-mode range. Its rail-to-rail output can improve use of the available output span. Verify offset voltage, input bias current, and common-mode limits for high-impedance sensors before finalizing the gain.

Battery-Powered Instrumentation
The TLV274ID's 550 uA supply current per channel makes it suitable for compact battery-powered instrumentation where four signal-processing channels share a 2.4 V to 16 V supply capability. Its quad integration reduces the number of amplifier packages, while 3 MHz bandwidth supports common low-frequency and moderate-bandwidth filter and buffer functions. The principal trade-off is general-purpose performance rather than specialized low-noise or high-speed operation. Use local bypass capacitors, monitor total channel current, and avoid excessive capacitive loading that could compromise feedback stability.
Được đề xuất
Data Acquisition Front End
The TLV274ID can condition multiple analog inputs in a data-acquisition front end because four channels operate from one 14-SOIC package at 550 uA per channel and 3 MHz bandwidth. A practical arrangement uses channels as unity-gain input buffers, anti-aliasing elements, or gain stages before an ADC. Rail-to-rail output provides flexibility when using output headroom, but the input range must remain within the verified operating region. Confirm ADC input range, settling requirements, source impedance, and filter stability to avoid acquisition errors.
Được đề xuất
Active Filtering
The TLV274ID's 3 MHz gain-bandwidth product makes it appropriate for active low-pass, high-pass, or notch-filter stages that do not require megahertz-class precision performance. Its 2.4 V/us slew rate helps preserve large-signal response, while 550 uA per channel supports four filter poles in one package. Component tolerances and op-amp noise still set achievable Q and cutoff accuracy. Validate noise gain against the 3 MHz bandwidth, add output isolation where capacitive loading is high, and reference the manufacturer guidance before targeting a stability margin.
Được đề xuất
Industrial Control Interfaces
The TLV274ID is suitable for general industrial signal interfaces where 16 V maximum supply, low per-channel current, and rail-to-rail output simplify scaling around a controller or sensor network. Four channels can buffer control, feedback, or diagnostic signals in a compact embedded assembly. The -40 C to 125 C specified range supports temperature-varying equipment, although actual system qualification remains application-specific. Maintain input signals inside the allowed common-mode region, provide local supply decoupling, and protect external pins against transients beyond the device ratings.
Được đề xuất
Communication Signal Buffering
The TLV274ID can buffer moderate-bandwidth communication or control signals in compact embedded systems because it combines 3 MHz bandwidth, 2.4 V/us slew rate, and rail-to-rail output. It is most appropriate for baseband analog interfaces rather than high-speed RF or long-distance line-driver tasks. Use short traces, a stable reference, and continuous feedback paths to prevent oscillation. Confirm input common-mode limits, output loading, and channel isolation, particularly when driving cables, connectors, or downstream protection devices whose capacitance can destabilize an amplifier stage.

Bảo phân biệt quan trọng

Ghi chú thiết kế
Budget approximately 2.2 mA for the four amplifiers when each TLV274ID channel operates at the verified nominal 550 uA supply current. This is an estimate based on 4 channels multiplied by 550 uA, not a guaranteed maximum. Include output load current, supply tolerance, and temperature effects in the actual power budget. Place a local supply bypass capacitor at each supply pin and keep the return path short to reduce supply disturbance across all four channels.
Do not interpret rail-to-rail output as rail-to-rail input. The verified data confirms the output feature but does not provide the input common-mode range. Signals approaching either supply rail must be checked against the manufacturer's input-range graph. Likewise, confirm offset voltage, bias current, output-current capability, and stability under the intended load before treating this general-purpose quad amplifier as a precision or high-capacitance driver.
Route each feedback loop as a short, continuous path around its assigned amplifier, and keep input and output traces away from one another where gain or phase margin is limited. Because four amplifiers share one package and supply network, ground bounce can affect every channel. Use a quiet ground plane, decouple the supply locally, and place protection or high-current switching paths away from the analog package to preserve signal integrity.
