TLV2472IP - Dual 6V 2.8MHz RRIO Op Amp | Texas Instruments
MPN: TLV2472IP ✓ פעילTLV2472IP סקירה
An operational amplifier is an analog active device that amplifies the voltage difference between its non-inverting and inverting inputs. A rail-to-rail input/output amplifier can operate with input and output voltages approaching either supply rail, improving usable signal range in low-voltage systems. The TLV2472 belongs to the operational-amplifier hierarchy within analog and mixed-signal integrated circuits.
Key characteristics include approximately 600 uA of supply current per channel, 1.4 V/us of slew rate, rail-to-rail input and output operation, and a 2.8 MHz gain-bandwidth product. These specifications position the device between very-low-power amplifiers and higher-bandwidth rail-to-rail amplifiers. Low input bias current of approximately 2.5 pA is especially useful when the amplifier must interface with high-impedance sensors.
The TLV2472 family combines low quiescent current with comparatively high AC performance for micropower designs. Its CMOS input stage provides low bias current, while the rail-to-rail output stage offers improved output swing and usable drive for ADC front ends and low-capacitance nodes. The dual configuration reduces package count when two matched amplifier functions are required in the same analog subsystem.
Typical applications include battery-powered sensor interfaces, portable medical and industrial measurement equipment, low-frequency active filters, transimpedance front ends, audio and communication signal conditioning, and buffering ADCs. Operation from low single-supply voltages is possible within the device's specified supply range, provided the input and output common-mode and absolute-maximum limits are respected.
For design work, verify the operating supply range, output-current capability, and load stability under the selected gain configuration. Place bypass capacitance close to the supply pins and avoid driving capacitive loads without isolation or additional compensation. Because the device is a through-hole PDIP package, board layout should also account for lead spacing and mechanical clearance rather than treating it as a surface-mount equivalent.

Battery-Powered Sensor Conditioning
The TLV2472IP suits low-power sensor front ends because each channel draws approximately 600 uA while providing a 2.8 MHz gain-bandwidth product and rail-to-rail input capability. It can amplify a bridge, thermistor, or resistive sensor output without requiring a supply substantially above the signal range. A typical implementation places the sensor directly on the non-inverting input and uses the inverting input for gain-setting feedback. Compared with a 1 MHz micropower amplifier, the TLV2472 offers more bandwidth for sensor dynamics, although offset error and input bias current still require attention near the lower supply rail.
מומלץ
Low-Power ADC Input Buffer
The TLV2472IP can buffer a sensor or filter output into a successive-approximation ADC without adding the higher supply current associated with many high-speed amplifiers. Its approximately 2.5 pA input bias current reduces loading of high-impedance sources, while the 2.8 MHz gain-bandwidth product gives useful bandwidth for settling at moderate closed-loop gains. The rail-to-rail output improves utilization of a 3.3 V or 5 V ADC input range. Because settling accuracy depends on gain, load capacitance, and the ADC acquisition window, the circuit should be validated with the actual source impedance rather than assuming the full 2.8 MHz bandwidth is usable at every gain.
מומלץ
Active Low-Frequency Filters
The TLV2472IP is appropriate for first- and second-order active filters operating below a few megahertz because it combines a 2.8 MHz gain-bandwidth product with 1.4 V/us slew rate. Both amplifier channels can implement a dual-feedback or multiple-feedback filter while consuming approximately 600 uA per channel. The dual package also allows one channel to perform filtering while the other supplies a gain or buffering function. Component tolerances will usually determine the filter's actual cutoff accuracy more than the amplifier's nominal bandwidth, but the amplifier must still support the required closed-loop gain, output swing, and capacitive loading for stable operation.
מומלץ
Portable Medical and Industrial Instrumentation
Low supply current, CMOS input characteristics, and dual-channel integration make the TLV2472IP useful in portable measurement equipment where multiple analog channels must share a limited power budget. It can condition pressure, temperature, or biochemical sensor signals in compact industrial and medical monitoring devices. The dual 8-pin PDIP package simplifies through-hole prototyping and repair, while approximately 600 uA per channel supports longer battery life than a conventional precision amplifier. For medical applications, engineers must also evaluate noise, offset drift, isolation requirements, applicable risk controls, and any application-specific qualification; the basic component qualification status does not by itself establish system compliance.
מומלץ
Communication and Audio Signal Buffering
The TLV2472IP can serve as a low-power buffer or gain stage for communication receivers and compact audio equipment where rail-to-rail swing improves analog headroom. Its 2.8 MHz bandwidth supports low-frequency voice-band and many control-signal paths, while the approximately 600 uA per-channel supply current is useful in battery-powered equipment. The 1.4 V/us slew rate helps preserve low-distortion operation for small-signal waveforms, although the application must remain within the output-current and stability limits. Feedback-network values should be checked for noise gain, and the output should not directly drive a loudspeaker; a separate driver stage is required.
מומלץ
Process-Control and Automation Analog Inputs
In industrial control equipment, the TLV2472IP can amplify low-level analog inputs before conversion or comparison when the signal bandwidth is limited and the supply budget is constrained. Its rail-to-rail input stage is useful near 3.3 V and 5 V rails, and the dual configuration can support two related sensor channels with one package. A practical implementation should include input clamping, common-mode rejection filtering, and protection against transients before the amplifier pins. Industrial systems also require operating-temperature verification, isolation where required, and compliance with the final equipment standard; those system-level obligations remain separate from the component's basic operating specifications.

הערות תכנון
Place the supply bypass capacitor immediately adjacent to the TLV2472IP positive supply pin and connect the negative supply pin to a continuous ground plane. Route both non-inverting inputs away from the supply, output, and clock-like fast edges to minimize parasitic pickup. In a through-hole PDIP layout, maintain adequate lead and body clearance from high-voltage nodes and account for the mechanical height of the package when installing it near larger components.
Budget the dual amplifier's approximately 600 uA per channel as 1.2 mA total, then add load current and any shutdown-state behavior. The verified data does not provide a shutdown-pin specification for the TLV2472IP, so do not assume the shutdown feature listed for other members of the TLV247x family applies to this ordering code. Confirm the exact pin functions, quiescent-current conditions, and operating-temperature limits from the TI ordering documentation before finalizing the power budget.
Do not assume that a rail-to-rail input stage allows inputs outside the supply rails, and do not use the amplifier as a comparator without checking output-swing and saturation recovery. High-impedance sources can amplify input-bias-current error, while capacitive loads can cause instability despite the nominal 2.8 MHz gain-bandwidth figure. Validate offset accuracy, settling, output drive, and stability in the final circuit with the intended source impedance, gain, load, and supply voltage.
