TLV2372IP - 3MHz Dual RRIO Op Amp | Texas Instruments
料号： TLV2372IP ✓ 量产中TLV2372IP 概述
An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The TLV2372 belongs to the rail-to-rail input/output amplifier family, where the input common-mode range and output swing extend toward the supply rails. Within the broader semiconductor hierarchy, it is a dual-channel amplifier IC, a linear amplifier, and a general-purpose analog signal-conditioning component.
The principal operating features include a 3 MHz bandwidth, 2.4 V/µs slew rate, 550 µA per channel supply current, 16 V maximum supply voltage, and 2.7 V minimum operating supply. Rail-to-rail input and output capability increases the usable signal range in systems whose operating points approach the positive or negative supply rail. The dual configuration provides two amplifiers in one 8-pin PDIP package, reducing board area compared with two separate single-channel devices.
The TLV2372 uses CMOS input circuitry to suit high-impedance sensor interfaces. Its rail-to-rail input stage allows signals near either supply rail to be referenced without requiring the usual input common-mode restriction of older amplifier designs. The 3 MHz bandwidth is suitable for moderate-frequency signal processing, while the 2.4 V/µs slew rate provides comparatively rapid output transitions. Designers should still account for output-load capacitance and stability when driving longer cables, large capacitors, or capacitive sensor networks.
Typical applications include low-power sensor conditioning, buffered instrumentation, transducer amplification, low-frequency active filters, audio preamplification, and general industrial signal processing. The dual topology is particularly useful when a design requires two closely related analog channels, such as differential measurement or gain stages that benefit from matched devices in the same package.
A key design consideration is the 550 µA per channel supply current, which supports low-power operation but may still be significant in long-duration battery-powered equipment. Confirm the complete operating envelope, input offset voltage, output-current capability, noise characteristics, and absolute maximum ratings against the manufacturer datasheet before releasing a production design.
This page consolidates verified manufacturer and distributor information, compares documented package-order variants, and adds practical application guidance, design notes, and search-oriented technical context for engineers evaluating the TLV2372IP.

典型应用
TLV2372IP 适用于 6 应用s: High-Impedance Sensor Signal Conditioning, Industrial Process Measurement, Low-Voltage Active Filtering, Audio Preamplification, Portable Instrumentation, General-Purpose Buffering and Amplification.
High-Impedance Sensor Signal Conditioning
The TLV2372IP suits high-impedance sensor interfaces because its CMOS input stage and rail-to-rail input capability reduce common-mode-range restrictions. The dual amplifier can condition one sensor channel or support a differential arrangement without requiring two separate packages. Its 3 MHz gain-bandwidth product provides useful bandwidth for low- and moderate-frequency measurements, while the 2.4 V/µs slew rate helps preserve waveform shape. Operate from the available 2.7 V to 16 V supply range, verify source-dependent bias current and offset in the final circuit, and add guarding around high-impedance input nodes to reduce leakage and interference.
推荐
Industrial Process Measurement
The TLV2372IP is appropriate for low-frequency industrial process-measurement front ends where sensor signals must be amplified before conversion or control. Rail-to-rail input and output operation increases usable swing at the 2.7 V minimum supply, and the 550 µA per-channel supply current can reduce the burden in distributed low-power instrumentation. The 3 MHz bandwidth and 2.4 V/µs slew rate are more than adequate for many temperature, pressure, and position sensor interfaces. The design must still account for industrial noise, grounding, input common-mode range under load, and the amplifier’s specified input and output limitations.
推荐
Low-Voltage Active Filtering
The dual TLV2372IP can implement active low-pass, high-pass, or notch sections in a compact 2.7 V-to-16 V circuit. Its 3 MHz gain-bandwidth product provides overhead for moderate closed-loop gains and filter corner frequencies, while rail-to-rail output swing helps utilize the available signal range. A designer should include output isolation when cascading stages because capacitive loading can affect stability and the 2.4 V/µs slew rate can become the limiting factor at higher frequencies or low load resistances. Validate component tolerances, noise, and transient response in the complete filter rather than relying only on nominal bandwidth.
推荐
Audio Preamplification
The TLV2372IP can provide dual-channel audio preamplification in compact analog equipment where rail-to-rail operation and a 2.4 V/µs slew rate are valuable. The 3 MHz bandwidth covers many audio-band requirements, and the dual package can process left and right channels locally. Because the device is not documented in the supplied data as a dedicated low-noise audio amplifier, input-referred noise, distortion, output-current capability, and stability into the next stage must be checked in the manufacturer data. The 2.7 V minimum supply also supports battery-powered and low-voltage portable equipment when the signal swing remains suitable.
推荐
Portable Instrumentation
The TLV2372IP fits portable, battery-powered instrumentation because it operates from 2.7 V and consumes 550 µA per channel. Rail-to-rail input and output capability is valuable when the measured signal can occupy a large portion of the available supply range, while the dual topology reduces package count in two-channel instruments. The 3 MHz bandwidth supports many low-frequency sensor measurements without requiring a faster amplifier. For a production design, confirm total quiescent current over temperature, input bias current for the selected sensor, output drive for the load, and power-consumption effects during acquisition and shutdown cycles.
推荐
General-Purpose Buffering and Amplification
The TLV2372IP provides two general-purpose amplifier channels for buffer, gain, summing, comparator-style, and signal-shaping functions in industrial or consumer electronics. Rail-to-rail input makes it easier to accept signals near the supply rails, while the 2.4 V/µs slew rate gives useful headroom for low-frequency dynamic waveforms. Its 8-PDIP through-hole package is particularly convenient for prototypes, educational systems, and through-hole industrial assemblies. Designers should verify noise, offset, common-mode rejection, output swing, and capacitive stability for the exact gain and load because those details were not included in the supplied verified excerpts.

设计说明
Budget the dual amplifier’s supply demand as approximately 1.1 mA at the documented 550 µA per-channel current, before adding load current and bias-path consumption. At a 3.3 V supply, the amplifier current corresponds to approximately 3.63 mW using the multiplication of 3.3 V and 1.1 mA; this is an estimate based on the verified supply-current specification. Verify the manufacturer’s quiescent-current test conditions and total supply-current limits before using this calculation as a production power budget.
For high-impedance sensor sources, keep the TLV2372IP input traces short, guard sensitive nodes where practical, and keep return-current paths away from the input conductors. The CMOS input stage makes the device useful with high source impedances, but leakage through board contamination or long copper traces can still degrade accuracy. Confirm the actual input bias current and offset-voltage values from the manufacturer datasheet, since those parameters were not present in the supplied verified excerpts.
Do not treat the rail-to-rail input designation as permission to exceed the absolute maximum supply voltage or operate outside the documented 2.7 V to 16 V range. Also avoid assuming that the complete output range reaches either supply rail under every load. Check the datasheet output-swing curves, load-current limits, common-mode range, and stability requirements at the intended gain. Decouple the supply close to the device with a suitable bypass capacitor selected from the manufacturer’s recommended circuit.
The 8-PDIP package is straightforward to route on a through-hole PCB, but analog signal paths still require deliberate grounding. Place the supply bypass capacitor near the device, provide an uninterrupted ground return, and separate high-current switching or digital return paths from sensor and amplifier inputs. If the amplifier drives a cable, connector, ADC, or other capacitive load, add the isolation or compensation required by the manufacturer’s stability guidance instead of assuming the 2.4 V/µs slew rate guarantees stability.
合规信息
The supplied verified excerpts do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The IP package designation and industrial temperature wording are not treated as proof of any compliance claim.
