TLV2474CD - Quad 2.8MHz RRIO Op Amp | Texas Instruments
MPN: TLV2474CD ✓ Hoạt độngTLV2474CD Tóm tắt
A CMOS operational amplifier is a voltage-gain device used to amplify, buffer, filter, or compare small analog signals. The TLV2474 belongs to the operational-amplifier hierarchy, which sits within analog amplifier ICs and broader semiconductor signal-processing systems. Rail-to-rail input and output operation extends usable signal range toward the supply rails, while the quad integration reduces the number of packages and board connections required in multichannel instrumentation.
The principal device characteristics are a 6 V maximum supply, 2.8 MHz gain-bandwidth product, four CMOS amplifier channels, and rail-to-rail input and output operation. These specifications position the device for low-voltage analog systems in which multiple moderate-bandwidth signal paths are required. The TLV2474 family also provides a shutdown capability, allowing a system designer to control amplifier activity when signal-chain power reduction is beneficial.
The TLV2474CD uses a CMOS implementation rather than a bipolar input stage. CMOS operational amplifiers commonly combine low static power requirements with rail-to-rail signal-handling capability, although input offset, bias current, noise, output-drive, and stability behavior must be evaluated for each specific operating point. The manufacturer datasheet should be consulted for the electrical characteristics, recommended operating conditions, pin assignments, and application guidance associated with the TLV2474 family.
Typical uses include low-voltage sensor conditioning, buffered instrumentation inputs, analog measurement chains, and general-purpose signal amplification. Because four channels are integrated in one package, the device can support parallel or sequential analog front ends where board area is constrained. Rail-to-rail operation is particularly useful when the signal or load approaches the available supply range, although output-current limits and output-voltage limits still apply under load.
When laying out a circuit, assign the supply and ground pins according to the pin-description table in the manufacturer datasheet, place bypassing capacitors close to those pins, and use short, low-impedance feedback paths. Confirm output stability with the selected feedback network and load capacitance. Treat the 2.8 MHz gain-bandwidth figure as the basis for closed-loop bandwidth selection rather than as a guarantee of usable signal bandwidth at every gain.
This product page combines the confirmed TLV2474 family characteristics, package information, sourcing guidance, same-family drop-in alternatives, and application-focused engineering guidance. It is intended to help engineers identify whether the TLV2474CD architecture and 14-pin integration match the voltage, bandwidth, channel-count, and signal-range requirements of a new analog design.

Ứng dụng tiêu biểu
TLV2474CD phù hợp cho 6 Áp dụngs: Low-Voltage Sensor Conditioning, Portable Measurement Instrumentation, Analog Signal Buffering, Active Filtering and Gain Stages, Communications Interface Conditioning, LED and Sensor Driver Front Ends.
Low-Voltage Sensor Conditioning
The TLV2474CD is suitable for conditioning signals from low-voltage sensors where four analog channels are needed on a compact board. Its 2.8 MHz gain-bandwidth product provides useful bandwidth for moderate-frequency sensor signals, while rail-to-rail input and output operation can help the amplifier work across much of the available 6 V supply range. A practical circuit may use one channel as a non-inverting or inverting gain stage, another as an active filter, and the remaining channels for reference or auxiliary signal paths. Confirm the sensor output range, input offset, bias-current behavior, and common-mode limits against the manufacturer datasheet before selecting the gain and feedback values.
Được đề xuất
Portable Measurement Instrumentation
The TLV2474CD fits portable measurement systems that combine several low-level analog inputs with a 6 V or lower supply. Quad integration allows a single package to handle multiple amplifier stages, reducing PCB component count compared with four separate single-channel devices. Its rail-to-rail input and output characteristics are useful when measurement signals occupy a substantial part of the low-voltage signal range, while the 2.8 MHz gain-bandwidth product supports moderately fast signal paths. Power the device from a low-noise rail, decouple the supply pins locally, and verify offset, noise, and output-drive performance against the required measurement resolution and sensor impedance.
Được đề xuất
Analog Signal Buffering
When a source has a high output impedance, the TLV2474CD can provide buffering before a converter, comparator, or downstream measurement stage. Rail-to-rail output operation helps preserve signal amplitude when the load requires the amplifier to approach its supply limits. The 2.8 MHz gain-bandwidth product must be considered when the source impedance, target load, and stability network determine the usable bandwidth. Use short source and return paths, avoid placing the input node near switching components, and check capacitive-load stability in the manufacturer datasheet. The shutdown function can also reduce activity when the buffered channel is not needed.
Được đề xuất
Active Filtering and Gain Stages
The four channels in the TLV2474CD can implement cascaded gain and active-filter stages for analog systems operating below 6 V. Its 2.8 MHz gain-bandwidth product allows useful closed-loop performance at moderate gains, although each amplifier’s actual bandwidth and phase margin depend on the feedback components. A two-stage architecture might use separate channels for anti-alias filtering, gain amplification, and output conditioning. Keep component tolerances consistent with the required cutoff accuracy, use low-noise and stable feedback networks, and simulate the complete filter rather than estimating each stage independently. The rail-to-rail output can reduce signal-headroom loss in low-voltage filter stages.
Được đề xuất
Communications Interface Conditioning
The TLV2474CD can support the receive-side signal conditioning of low-voltage communications equipment when the required bandwidth remains within the 2.8 MHz gain-bandwidth capability. Four channels provide a practical way to condition or monitor multiple related low-speed signals without using four separate packages. Rail-to-rail input and output behavior can be beneficial in compact interface circuits with limited supply headroom. Designers should control impedance between the source, amplifier, and downstream device, maintain short feedback paths, and separate sensitive analog routing from switching-node energy. The shutdown capability can be used to control amplifier state, but its electrical behavior must be taken from the manufacturer datasheet.
Được đề xuất
LED and Sensor Driver Front Ends
The TLV2474CD can serve as the low-voltage control front end for sensor and LED-related circuitry when the output current and stability requirements are compatible with the device. Rail-to-rail output operation can improve control range in a compact 6 V system, and the 2.8 MHz gain-bandwidth product is suitable for slow feedback loops and moderate-frequency modulation. Four channels can control or monitor several related signals. Because the confirmed family description emphasizes high-drive operational-amplifier capability but does not provide a specific output-current rating, verify output current, output swing, capacitive-load behavior, and thermal performance before driving LEDs or other loads directly. Use the manufacturer limits rather than assuming unlimited drive capability.

Ghi chú thiết kế
Place the supply-bypass capacitor adjacent to the TLV2474CD power and ground pins, and use a short, low-impedance return path to the circuit ground. The 14-pin SOIC footprint should be checked against the TI package drawing and PCB land pattern. Keep input and feedback routes away from switching nodes and high-current return paths because the device is intended for precision analog amplification where board-level coupling can dominate device-level performance.
Do not assume that rail-to-rail input and output operation permits operation beyond the device's absolute maximum ratings or that the output can drive every load. Check supply voltage, input common-mode range, output swing, output current, and capacitive-load stability from the manufacturer datasheet. Configure the shutdown pin so it cannot float, and confirm its active state and timing before using it for power sequencing.
Derive each closed-loop bandwidth from the 2.8 MHz gain-bandwidth product and the selected noise gain rather than treating 2.8 MHz as usable bandwidth at every configuration. Use short feedback components, maintain symmetrical routing where practical, and keep high-impedance input nodes physically small. For sensor inputs, assess bias-current error against source impedance and verify settling behavior for the required signal rate.
The TLV2474CD is a low-voltage analog amplifier rather than a discrete power device, but output drive still creates finite power dissipation. Calculate dissipation from the actual output voltage, load current, and supply voltage, then compare the resulting temperature rise with the package limits in the manufacturer datasheet. Do not use the high-drive family description as a substitute for a specific output-current rating when sizing a load.
