TLV2474IN - 2.8MHz Quad RRIO Op Amp | Texas Instruments
MPN: TLV2474IN ✓ نشطTLV2474IN نظرة عامة
An operational amplifier is an analog integrated circuit that compares an inverting input with a non-inverting input and amplifies the voltage difference. The rail-to-rail input and output architecture allows the TLV2474IN to approach the positive and negative supply rails during signal operation. This characteristic is useful in battery-powered equipment, portable instrumentation, low-voltage sensor interfaces, and other systems in which usable input or output swing is limited by the available supply voltage.
The TLV2474IN combines four amplifier channels in one package, reducing board area compared with four individually packaged amplifiers. Its 2.8 MHz gain-bandwidth product supports applications requiring moderate closed-loop bandwidth, including signal buffering, active filtering, differential amplification, and low-level conditioning. The 600 uA-per-channel supply current is suited to compact and power-conscious systems where each amplifier channel must balance bandwidth, drive capability, and power consumption.
Texas Instruments describes the TLV247x family as CMOS rail-to-rail input/output operational amplifiers that establish a new performance point between supply current and AC performance. The family combines low channel current with a 2.8 MHz gain-bandwidth product and high output-drive capability. These characteristics make the TLV2474IN useful when several analog channels must operate from the same supply while maintaining a compact 14-pin PDIP footprint.
Typical circuit roles include buffering sensor outputs, amplifying low-level analog signals, active low-pass filtering, and driving ADC inputs. Because the amplifier supports rail-to-rail input and output operation, designers can work with signals near the supply rails. The 2.8 MHz gain-bandwidth product is especially relevant to filters and gain stages whose useful bandwidth must remain comfortably below the amplifier's closed-loop bandwidth limit.
Design the surrounding circuit around the manufacturer's recommended operating region, verify input and output swing under the intended load, and account for input common-mode and output limits across the full -40°C to 125°C temperature range. A 14-pin PDIP package also requires adequate lead spacing and mechanical clearance in through-hole PCB layouts, especially when analog traces are routed beside switching nodes or high-current paths.
This product page organizes the verified manufacturer specifications, exact TLV2474IN package information, sourcing questions, and practical selection guidance. It also distinguishes genuine same-footprint replacements from alternatives that require a different package, helping engineers assess whether a candidate can be substituted without changing the PCB footprint.

التطبيقات النموذجية
TLV2474IN مناسب لـ 6 التطبيقs: Portable Sensor Signal Conditioning, Industrial Data Acquisition, Precision Active Filtering, Audio and Communication Buffering, Battery-Powered Instrument Front Ends, ADC Driver and Reference Conditioning.
Portable Sensor Signal Conditioning
The TLV2474IN fits four-channel sensor conditioning because each rail-to-rail input can accept signals approaching the supply rails while consuming 600 uA per channel. The amplifier can buffer sensor outputs or provide gain before an ADC without requiring four separate packages. Its 2.8 MHz gain-bandwidth product gives useful bandwidth for moderate-speed pressure, temperature, and position sensing, while the -40°C to 125°C range supports industrial and automotive-adjacent environments. Verify the actual sensor output range against the amplifier's recommended common-mode limits and confirm output swing with the selected load.

Industrial Data Acquisition
The four channels of the TLV2474IN can condition several analog inputs in a compact industrial measurement system. Rail-to-rail input operation is valuable when sensor signals occupy much of the available 6 V-class supply range, and the 2.8 MHz gain-bandwidth product supports moderate-bandwidth acquisition channels. The 600 uA-per-channel operating current helps control total demand in distributed measurement nodes. Layout should keep sensitive input traces away from relay, motor, and power-conversion switching paths, while the 14-pin PDIP package provides straightforward through-hole assembly and inspection.
موصى به
Precision Active Filtering
The TLV2474IN is suitable for active low-pass, high-pass, or notch-filter stages where multiple channels and moderate bandwidth are required. Its 2.8 MHz gain-bandwidth product gives a useful basis for filter selection, while rail-to-rail output operation can improve signal utilization at low supply voltages. Four channels in one 14-pin PDIP package reduce component count compared with separate single-amplifier packages. Set closed-loop gains and component tolerances according to the manufacturer's guidance, and verify stability, output swing, and temperature-dependent behavior in the final filter implementation.
موصى به
Audio and Communication Buffering
The TLV2474IN can provide input and output buffering in low-level audio or communication interfaces when low channel power and rail-to-rail swing are priorities. Its 600 uA-per-channel current is suitable for compact line-level stages, and the 2.8 MHz gain-bandwidth product is more than adequate for many audio conditioning paths. The device's high output-drive capability is identified by the manufacturer as an improvement over older micropower amplifiers. Audio designs should still account for distortion, channel-to-channel matching, and load requirements, and should keep the input network away from noisy switching nodes.

Battery-Powered Instrument Front Ends
The TLV2474IN supports battery-powered instrument front ends where four low-power analog channels are needed within a limited board area. The specified 600 uA-per-channel current reduces the amplifier contribution to system demand, while rail-to-rail input and output behavior can improve utilization of a low-voltage supply. The 2.8 MHz gain-bandwidth product supports buffering and modest closed-loop gain stages rather than demanding high-speed signal paths. Validate total battery load, startup behavior, ground offset, and output settling before using the device with successive low-current measurement channels.
موصى به
ADC Driver and Reference Conditioning
The TLV2474IN can drive or buffer the input of a multi-channel data converter when the required signal bandwidth is moderate. Rail-to-rail output capability helps maximize the usable range of a low-voltage ADC front end, and the 2.8 MHz gain-bandwidth product provides useful headroom for common acquisition filters. Because the TLV2474IN contains four channels, it can support simultaneous or sequential conditioning paths in one package. Verify ADC input capacitance, settling requirements, kickback behavior, and acquisition timing against the selected converter before finalizing the gain and filter network.

ملاحظات التصميم
Budget the four amplifier channels separately from the rest of the system supply. The manufacturer specifies 600 uA per channel, corresponding to a nominal 2.4 mA when all four channels are active. Add the load current from downstream sensors or ADC inputs, and verify the regulator's dropout behavior at the lowest battery or supply voltage. Decoupling should follow the manufacturer recommendations, with short, low-impedance connections between each supply pin and its local capacitor.
Keep the four analog input paths short and away from switching-node copper, inductors, and high-current return paths. A 14-pin PDIP footprint permits relatively wide lead spacing, but signal still needs a low-impedance ground reference. Place input compensation or filtering components close to the associated amplifier pins, and maintain a continuous ground path under the device where practical to reduce ground-drop and coupling effects.
Rail-to-rail input and output operation does not eliminate the need to check input common-mode limits, output swing, and load-current capability for the actual circuit. Do not infer that the output can reach either supply rail under every load. Also confirm the pin functions for the 14-pin PDIP package against the manufacturer datasheet, especially when replacing an amplifier with different shutdown or enable arrangements.
Select closed-loop gains so that the wanted signal bandwidth remains below the 2.8 MHz gain-bandwidth product with adequate phase-margin margin. The open-loop gain and unity-gain stability characteristics vary with circuit topology and load, so use the manufacturer's recommended compensation and output-loading limits for filter and precision gain stages. Place any noise-gain shaping components directly at the amplifier pins to minimize parasitic feedback.
