TLV2635ID - 4-Channel 9 MHz RRO Op Amp | Texas Instruments
MPN： TLV2635ID ✓ 啟用中TLV2635ID 概覽
An operational amplifier, commonly called an op amp, is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The TLV2635 family belongs to the linear amplifier hierarchy: operational amplifier, analog amplifier, amplifier IC, and semiconductor. Rail-to-rail output means the output voltage can approach the supply rails under suitable load and output conditions, making the amplifier useful in systems that require signal swing across most of the available supply-voltage range.
The principal performance features are a 9 MHz gain-bandwidth product, approximately 730 uA of supply current per channel, and rail-to-rail output operation. Shutdown support can reduce power consumption when an enabled state is not required. The four-circuit configuration is particularly useful for filtering, buffering, level translation, instrumentation, and general analog signal-conditioning blocks that otherwise would require several separate amplifier packages.
The TLV2635 combines single-supply operation with wide bandwidth, allowing it to operate from one positive rail where dual-supply op amps would otherwise be required. Because it is a low-power amplifier, its internal operating current is substantially lower than that of many general-purpose high-speed amplifiers. Engineers should still evaluate output swing, capacitive-load stability, input common-mode behavior, and gain-bandwidth interaction for the exact operating point before finalizing a circuit.
Typical uses include low-frequency sensor conditioning, active filtering, audio and communication-signal interfaces, current-voltage conversion, and embedded control systems. The quad package is attractive when four channels must be routed to a nearby analog subsystem, provided the individual amplifier requirements are compatible with the family-wide bandwidth and power characteristics.
A key design consideration is shutdown-state behavior. The manufacturer documents this family as operating-amplifier circuits with and without shutdown, but shutdown timing, logic levels, and state-specific output conditions must be confirmed in the TLV2635 datasheet before sequencing multiple analog channels. Decoupling capacitors should be placed close to the supply pins, and sensitive inputs should be kept away from high-impedance routing that can increase coupling and offset error.
This product page organizes the key electrical characteristics, package information, practical use cases, design guidance, and a conservative comparison of identified alternatives. It also separates confirmed manufacturer and distributor information from engineering checks that still require schematic-level validation.

典型應用
TLV2635ID 適用於 6 應用s: Multi-Sensor Signal Conditioning, Active Filtering and Buffering, Battery-Powered Instrumentation, Communication Interface Buffering, Audio and Low-Frequency Analog, Current-to-Voltage Conversion.
Multi-Sensor Signal Conditioning
The TLV2635ID fits multi-sensor signal conditioning because it combines four amplifier sections with a 9 MHz gain-bandwidth product and approximately 730 uA supply current per channel. Each channel can buffer or amplify a sensor output without requiring four separate packages, helping reduce board area in monitoring and industrial-control systems. Rail-to-rail output can also increase the usable range available to a downstream ADC or controller, although each sensor output must remain inside the amplifier's input common-mode limits. Use short input traces, a stable reference return, and local supply decoupling to reduce offset coupling and noise pickup.
推薦
Active Filtering and Buffering
The four-channel TLV2635ID is useful for active filter and buffer sections that need more than audio-bandwidth response. Its 9 MHz gain-bandwidth product provides closed-loop bandwidth for moderate-frequency filters, while the low approximately 730 uA per-channel current supports multiple analog stages in portable or power-constrained equipment. The amplifier can sit close to a sensor or converter to isolate the source from downstream capacitance. Select resistor and capacitor values around the required pole or zero, and verify stability with the intended load because capacitive loading can alter the response.
推薦
Battery-Powered Instrumentation
The TLV2635ID is well suited to battery-powered instrumentation that requires several low-power analog channels. Four amplifiers in one 16-pin SOIC reduce the package count compared with four separate single amplifiers, while approximately 730 uA per channel helps limit the analog power budget. The single-supply architecture simplifies system wiring when the signal source operates near the positive rail. For longer battery life, use shutdown support to disable channels that are not needed and evaluate the shutdown timing in the system control sequence.
推薦
Communication Interface Buffering
The TLV2635ID can provide input buffering, gain, and level translation for moderate-bandwidth communication interfaces. Its 9 MHz gain-bandwidth product is substantially faster than a basic DC-only amplifier, allowing the same device to handle low-frequency control signals and higher-rate analog traffic. Rail-to-rail output helps the amplifier drive a downstream analog or mixed-signal device across much of the available supply range. Keep input and return paths compact, provide adequate supply bypassing, and confirm the required signal bandwidth, slew rate, output loading, and common-mode limits before deployment.
推薦
Audio and Low-Frequency Analog
The TLV2635ID can be used in low-frequency audio and general analog paths where four channels, rail-to-rail output, and a 9 MHz gain-bandwidth product provide more flexibility than a unity-gain audio buffer. The approximately 730 uA per-channel current is useful in compact line-level or preamplifier circuitry. Single-supply operation simplifies systems that cannot provide a split rail. Evaluate output swing into the intended load, keep the shutdown pin in a defined state during normal operation, and use short, shielded routing for sensitive high-impedance sources.
推薦
Current-to-Voltage Conversion
The TLV2635ID can form the active element in transimpedance and current-to-voltage conversion stages when the required signal bandwidth fits its 9 MHz gain-bandwidth product. Four channels allow multiple sensors or branches to be converted without using separate amplifier packages. A practical transimpedance design must account for feedback resistor capacitance, sensor or shunt capacitance, and amplifier stability; otherwise parasitic capacitance can create peaking or oscillation. Place the feedback network close to the amplifier, maintain a compact input loop, and confirm the exact input common-mode range before selecting the shunt resistance.

設計說明
Place the supply bypass capacitor directly between the V+ and ground pins. Keep the connection short because package inductance and trace resistance can create an effective series impedance that degrades transient response. Check the maximum capacitive load and output-current behavior in the manufacturer datasheet before adding large capacitors directly to the output.
Route each inverting-input feedback path directly between the amplifier output and its input pin. Keep the loop physically small to minimize parasitic capacitance, which can alter the effective noise gain and cause peaking or instability. High-impedance non-inverting inputs should be short and surrounded by a grounded reference where practical.
Do not leave the shutdown connection floating. Define its inactive state in the system reset and power-sequencing logic, and confirm the required logic level and timing from the manufacturer datasheet. Shutdown behavior and output states can differ by family member, so treating the pin as an unused control may result in unintended channel operation.
Choose the closed-loop gain and feedback network based on the 9 MHz gain-bandwidth product rather than selecting the highest possible gain. The ratio of gain-bandwidth product to closed-loop gain indicates the approximate maximum signal bandwidth, but source impedance, load capacitance, and output-current capability can reduce practical performance. Simulate the complete loading condition before release.
