TLV2770ID - 5.1 MHz High-Slew-Rate Op Amp | TI
料号： TLV2770ID ✓ 量产中TLV2770ID 概述
A CMOS operational amplifier is an analog integrated circuit that amplifies voltage differences while operating from a positive supply, a negative supply, or a single supply configuration. Operational amplifiers form the foundation of analog signal chains, where they perform functions such as buffering, amplification, filtering, level shifting, current-to-voltage conversion, and active feedback control. The TLV2770 combines a wide bandwidth with high slew rate to support signals that require both fast response and accurate output voltage control.
The headline specifications provide a clear balance between speed and efficiency. A 5.1 MHz gain-bandwidth product supports moderate-frequency signal amplification, while the 10.5 V/μs slew rate allows the output to change rapidly without the severe distortion associated with slower amplifiers. Rail-to-rail output operation improves usable output range in low-voltage systems, and the approximately 1 mA supply current helps limit power consumption when the shutdown function is not being used.
The TLV2770ID combines high-speed AC performance with the DC precision expected of the TLV277x CMOS family. Its single-amplifier configuration avoids the additional channels and package area associated with a dual or quad device. An integrated shutdown path supports designs that periodically disable the amplifier, reducing activity during inactive intervals. Designers should still confirm shutdown-control polarity, timing, output behavior, and input-state requirements against the manufacturer datasheet before finalizing a power-sequencing scheme.
Typical uses include sensor-signal conditioning, low-level analog amplification, active filtering, data-acquisition front ends, industrial control loops, and portable instrumentation. The 8-pin SOIC format supports conventional PCB assembly and rework, while the 2.7 V to 5.5 V operating range accommodates both 3.3 V and 5 V systems. In battery-powered equipment, low supply current and shutdown capability can help reduce average energy use when the amplifier operates intermittently.
The main design consideration is the tradeoff between speed, output swing, noise, and power. The 10.5 V/μs slew rate makes the amplifier appropriate for fast signal transitions, but it may require additional attention to output-load drive, feedback stability, input common-mode range, and decoupling when driving long PCB traces or capacitive loads. Place the bypass capacitor close to the supply pins and use the pin-description table in the manufacturer datasheet when assigning PCB tracks.
This product page consolidates the manufacturer specifications, verified package information, sourcing guidance, comparison limits, and practical application considerations into a focused engineering reference. It also distinguishes true pin-compatible alternatives from related amplifiers that require different shutdown connections, preventing a superficially similar device from being treated as a drop-in replacement.

典型应用
TLV2770ID 适用于 6 应用s: Low-Power Sensor Signal Conditioning, Portable Data-Acquisition Front End, Active Filtering and Signal Shaping, Industrial Control and Monitoring, Test and Measurement Signal Conditioning, Portable Audio and Communication Interfaces.
Low-Power Sensor Signal Conditioning
The TLV2770ID fits low-power sensor front ends that need more response than a general-purpose slow amplifier can provide. Its 5.1 MHz gain-bandwidth product supports moderate-bandwidth conditioning, while the 10.5 V/μs slew rate allows the output to follow sensor transitions without pronounced slew-rate distortion. The approximately 1 mA supply current per channel is useful in portable equipment, and shutdown can disable the amplifier during inactive measurement periods. Design the input network around the sensor output impedance and verify input common-mode limits, offset, noise, and biasing against the manufacturer electrical characteristics.
推荐
Portable Data-Acquisition Front End
The TLV2770ID can condition sensor outputs before conversion in a portable data-acquisition system. Its 5.1 MHz gain-bandwidth product provides useful bandwidth for many moderate-rate signals, and the 10.5 V/μs slew rate supports rapid output transitions during acquisition cycles. Rail-to-rail output operation is valuable in 2.7 V to 5.5 V systems where minimizing unused signal range improves utilization of the available output voltage. Shutdown is useful when acquisition is intermittent, although timing and output-state behavior must be checked in the datasheet before using shutdown as a sampling control mechanism.
推荐
Active Filtering and Signal Shaping
The TLV2770ID is appropriate for active filters and signal-shaping stages requiring a faster output than a low-bandwidth general-purpose amplifier. Its 5.1 MHz gain-bandwidth product gives designers room for moderate closed-loop gains, while the 10.5 V/μs slew rate helps preserve waveform shape at higher signal frequencies and low amplitudes. Rail-to-rail output swing increases usable signal range in low-voltage filter circuits. Component values must be selected with the amplifier’s gain-bandwidth and stability behavior in mind, and feedback-loop layout should be kept compact to reduce parasitic feedback and oscillation risk.
推荐
Industrial Control and Monitoring
The TLV2770ID can amplify and buffer monitoring signals in industrial control equipment where a 2.7 V to 5.5 V supply range and fast output response are useful. The 5.1 MHz gain-bandwidth product supports moderate-frequency process signals, and the 10.5 V/μs slew rate improves response during changing sensor or control conditions. High output drive gives designers margin for ordinary buffer and drive arrangements, although external buffering may still be needed for long lines or heavy capacitive loads. Industrial designs should also consider noise, offset, transient immunity, and thermal performance across the intended enclosure temperature range.
推荐
Test and Measurement Signal Conditioning
The TLV2770ID is suitable for buffering and conditioning signals in compact test and measurement instruments. Its 10.5 V/μs slew rate supports faster waveform transitions than many low-power amplifiers, while the approximately 1 mA supply current can simplify power budgeting in multi-channel systems. The single amplifier in an 8-pin SOIC also provides a compact implementation when only one high-speed signal requires conversion. For precision measurement paths, verify input offset, input bias current, noise density, and common-mode performance at the actual signal amplitude; high bandwidth alone does not establish metrological accuracy.
推荐
Portable Audio and Communication Interfaces
The TLV2770ID can serve as a general-purpose amplifier in portable audio, communications, and interface circuits that need rail-to-rail output swing and rapid settling. The 5.1 MHz gain-bandwidth product handles moderate-bandwidth signals, and the 10.5 V/μs slew rate improves large-signal response compared with slower low-power amplifiers. Shutdown provides a way to reduce activity when the interface is not used, supporting battery-conscious designs. Confirm the actual output-noise performance, load capability, and shutdown timing before selecting it for microphone, line-output, or high-fidelity audio signal paths.

设计说明
Place the supply bypass capacitor immediately beside the power and ground pins, with a short and low-inductance return path. Keep the feedback components and the amplifier output routing compact because parasitic capacitance in the feedback loop can affect stability and ringing. Follow the pin-description table in the manufacturer datasheet for the exact SOIC orientation and verify that the shutdown net meets its specified input-voltage limits.
The 5.1 MHz gain-bandwidth product and 10.5 V/μs slew rate make trace length, capacitance, and feedback-loop geometry increasingly important. Keep sensitive input nodes away from the output and shutdown pins, use a solid ground reference, and avoid long unprotected routes. When driving a long cable or significant load capacitance, evaluate an isolation resistor or separate output buffer instead of relying on the amplifier to drive the load directly.
Use the shutdown control only after confirming its polarity, logic thresholds, transition behavior, and output state from the manufacturer documentation. Shutdown can reduce power in intermittent systems, but control sequencing must prevent back-powering an unpowered amplifier through connected signal lines. For battery-powered equipment, include the amplifier’s operating and shutdown current in the average-power calculation and account for leakage through external input or output networks.
Do not substitute a related amplifier solely because it uses an 8-pin SOIC package. The OPA726 and TLV2770 have similar pinouts, but their shutdown pins are different, so they are not true drop-in choices without schematic or PCB changes. Likewise, TLV2771-family devices without shutdown require pin-level review. Verify every connected pin, the supply range, AC limits, output drive, and shutdown behavior before approving any replacement.
合规信息
Compliance and qualification attributes require confirmation from the Texas Instruments product documentation for the exact ordering code. The TLV2770ID is identified as a standard general-purpose amplifier rather than an explicitly automotive-qualified ordering option.
