TLV272ID - Dual 16V 3MHz R-R Op Amp | Texas Instruments
MPN： TLV272ID ✓ 啟用中TLV272ID 概覽
An operational amplifier is an active analog component that amplifies the voltage difference between its differential inputs while using negative feedback to set closed-loop gain, filtering, or integration behavior. Within the hierarchy of integrated circuits, the TLV272 belongs to the operational-amplifier class, then to voltage-feedback amplifiers, analog ICs, and ultimately semiconductor signal-conditioning devices. Rail-to-rail output allows the output voltage to approach the supply limits at its rated operating conditions.
Key verified characteristics include a 3 MHz gain-bandwidth product, dual-amplifier configuration, 550 uA supply current per channel, 16 V maximum supply rating, and rail-to-rail output operation. The 3 MHz bandwidth supports higher-frequency signal paths than very-low-bandwidth micropower amplifiers, while the 550 uA per-channel current supports battery-conscious designs. The -40 C to +125 C grade is suitable for industrial temperature requirements when the complete circuit is qualified for those conditions.
The TLV272ID combines two independent amplifiers in one SOIC-8, reducing board area compared with two separate single-channel packages. Its operating characteristics are relevant for sensor interfaces, audio paths, filtering, and general voltage amplification. However, the provided web data does not specify input offset voltage, input bias current, noise density, output-current capability, or input common-mode range, so these values must be confirmed in the manufacturer datasheet before precision design.
Typical uses include low-frequency audio amplification, buffered sensor outputs, active filters, and portable measurement circuits. When operating from a 2.7 V supply, engineers must confirm that output swing, input range, and load requirements remain acceptable at the selected signal amplitudes. The 16 V maximum rating does not by itself establish safe operation at every intermediate rail or temperature combination.
The main PCB consideration is decoupling. Place input and output-conditioning components close to their associated pins, route feedback loops compactly, and provide stable supply bypassing. Stable operation also depends on the required common-mode and output ranges, load impedance, feedback topology, and output-current demand.

典型應用
TLV272ID 適用於 6 應用s: Battery-Powered Sensor Interface, Portable Audio Signal Path, Active Filtering and Control Loops, Industrial Instrumentation Signal Conditioning, Data-Acquisition Analog Front End, Low-Voltage Embedded Control.
Battery-Powered Sensor Interface
The TLV272ID fits low-voltage sensor-conditioning blocks because its verified 2.7 V minimum supply and approximately 550 uA supply current per channel support conservative battery-powered operation. Two amplifiers can be packaged in one 8-pin SOIC, reducing component count when a sensor path requires gain and filtering. Its 3 MHz bandwidth is ample for many moderate-bandwidth sensor signals. Place the device beside the sensor and its RC network, bypass the supply locally, and verify that sensor voltages remain inside the amplifier's unverified input common-mode range. Confirm output headroom for the selected load; rail-to-rail output does not mean zero output voltage at every current.
推薦
Portable Audio Signal Path
The TLV272ID's 550 uA-per-channel supply current and 3 MHz gain-bandwidth product make it relevant to small portable audio paths where both power and bandwidth matter. Two channels in an 8-pin SOIC can support stereo volume, gain, or active-filter stages without requiring two single packages. Rail-to-rail output helps utilize a 2.7 V or higher supply, although output swing must still be checked under the actual load and frequency. Keep the feedback loop short, return the output reference cleanly, and compare the amplifier noise with the audio source because noise density was not present in the verified records.
推薦
Active Filtering and Control Loops
With a verified 3 MHz gain-bandwidth product, the TLV272ID can implement active filters and feedback loops whose useful signal bandwidth remains well below that level. Its dual architecture supports two poles, a combined gain-and-filter stage, or a second control channel within one SOIC-8. Stable feedback depends on the exact noise-gain network, load, and output-capacitance conditions, which were not supplied in the verified records. Build each RC network close to its input or feedback node, probe loop gain during validation, and avoid loading the output with unnecessarily long PCB traces that can add parasitic capacitance.
推薦
Industrial Instrumentation Signal Conditioning
The TLV272ID's -40 C to +125 C verified temperature range supports industrial instrumentation concepts when the full assembly and analog input levels meet its limits. The dual SOIC-8 channel count is useful for amplifying or filtering two related sensor signals without doubling package count. Its 16 V maximum supply accommodates many conventional industrial rails below the ceiling, but engineers must validate transient protection and common-mode levels separately. Keep sensitive input traces away from switching nodes, use a stable reference or ground plane, and confirm input bias current and common-mode limits from the manufacturer documentation before choosing it for high-impedance transducers.
推薦
Data-Acquisition Analog Front End
The TLV272ID can serve as a dual gain or driver stage ahead of an ADC when the required signal bandwidth is consistent with its verified 3 MHz gain-bandwidth product. Two channels fit an 8-pin SOIC, allowing one signal to be amplified and another filtered or cross-sampled. Input offset, bias current, noise, settling behavior, and output-current limits were not included in the retrieved data, so precision ADC designs must verify those parameters before committing. Place the amplifier near the ADC input, minimize trace capacitance, establish a solid return path, and validate settling against the converter's acquisition window.
推薦
Low-Voltage Embedded Control
A 2.7 V minimum operating supply makes the TLV272ID suitable for low-voltage embedded analog blocks when an MCU or sensor hub operates from a 3.3 V rail. Its dual channels can condition current, voltage, or feedback signals while consuming approximately 550 uA per channel under the verified conditions. Embedded boards often combine fast digital switching with sensitive analog nodes, so decouple the amplifier supply locally and route analog traces away from clock and power-converter nodes. Because input range and output-drive figures were not provided, verify them against the actual rail, ADC input, and source impedance rather than assuming ideal rail-to-rail behavior.

主要差異化特點
- The target combines two channels with low channel supply current (對比Single-channel alternatives)
- Verified operating envelope supports low- and higher-voltage analog rails (對比Devices limited to a narrower 5 V maximum supply)
- Rail-to-rail output improves low-voltage design flexibility (對比Non-rail-to-rail-output amplifiers)
設計說明
Place the TLV272ID close to the source and load it serves, then keep the feedback components adjacent to the appropriate input and output pins. This minimizes parasitic capacitance in the 3 MHz device and reduces susceptibility to board-level coupling. Route the ground return directly beneath the analog signal path where practical, and keep switching-regulator traces and high-current paths away from high-impedance inputs. Verify the SOIC orientation against the authoritative datasheet pin table before fabrication.
Power-budget using the verified approximate 550 uA per channel before adding load current. Estimated: two channels at 550 uA each consume about 1.10 mA from the amplifier supply at the stated test condition. This is a calculated figure, not a manufacturer maximum. Actual consumption changes with supply voltage, common-mode level, output activity, and channel state. Check the complete circuit against battery capacity and ensure rail transients remain below the 16 V maximum rating.
Validate closed-loop stability with the real feedback network, source impedance, and load. The retrieved information verifies a 3 MHz gain-bandwidth product but does not state noise gain, capacitive-load tolerance, settling time, or output-current capability. Those omissions matter near the amplifier's practical bandwidth limit. Prototype with the intended RC values and PCB parasitics, probe overshoot and ringing, and add an isolation resistor only after evaluating its effect on gain and bandwidth.
