TLV2760CD - 3.6V, 500kHz Micropower RRIO Op Amp with Shutdown | Texas Instruments
부품 번호: TLV2760CD ✓ 활성TLV2760CD 개요
An operational amplifier is a voltage-gain building block that compares two input terminals and drives its output to control loops, buffer levels, or amplify small sensor signals. The TLV2760 belongs to the hierarchy low-noise amplifier -> operational amplifier -> analog signal conditioning IC -> semiconductor, and its rail-to-rail (RRIO) input and output stages let it operate directly across the full supply rails without headroom constraints.
Key features of the TLV2760 include 500 kHz bandwidth from only 20 µA of supply current, rail-to-rail inputs and outputs, a shutdown pin for reducing supply current when the amplifier is idle, 3.5 mV typical offset voltage, and approximately 3 pA input bias current. The wide common-mode input range reaches both supply rails, which simplifies sensor front-ends powered directly from cells.
Architecturally, the device is a CMOS single-supply amplifier that is fully specified down to a 1.8 V rail and characterized at 1.8 V and 2.4 V supply conditions. The maximum recommended supply voltage of 3.6 V permits operation from 1.8 V supplies down to 0.9 V (two AA or AAA cells), giving designers flexibility for energy-harvesting and portable systems.
Typical applications include portable sensor conditioning, battery-powered instrumentation, low-power filter stages, transimpedance pre-amplifiers for photodiodes and pH electrodes, and general embedded signal conditioning where board area and supply current are tightly constrained.
When designing with the TLV2760, keep the shutdown pin compatible with the host logic levels and observe the maximum recommended supply voltage of 3.6 V. Because the amplifier is intended for low-voltage rails, verify that any external feedback network and the surrounding ADC front end operate at compatible common-mode and output swing levels.
This page consolidates distributor availability, drop-in replacement candidates, comparison data and practical layout guidance in one place, so engineers can shortlist the part faster than by reading a datasheet alone.

일반적인 애플리케이션
TLV2760CD 적합 용도: 6 애플리케이션s: Battery-Powered Sensor Signal Conditioning, Portable Medical and Wearable Monitoring, Transimpedance Photodiode Preamplifier, Low-Power Active Filter Stages, Industrial Process Sensing and Data Acquisition, Low-Voltage Buffering and Level Shifting.
Battery-Powered Sensor Signal Conditioning
The TLV2760CD suits low-voltage sensor front ends because it operates from a 1.8 V rail, consumes about 20 µA of quiescent current and offers rail-to-rail inputs that accept the full 0 V to 1.8 V output range of a resistive bridge or potentiometer. With 3 pA input bias current, the amplifier does not load the sensor, so a 1 MΩ divider still resolves microvolt-level changes. Place the device directly at the sensor pins and drive the ADC front end from the same 1.8 V cell, keeping the signal path above the ground rail. The shutdown pin lets the node drop to a near-zero current state between readings, which directly extends battery life in handheld meters and environmental monitors.

Portable Medical and Wearable Monitoring
Wearable and portable monitoring devices operate from very small budgets, and the TLV2760CD delivers 500 kHz bandwidth from only 20 µA of supply current. Rail-to-rail input and output stages allow the amplifier to work directly with the small, battery-derived signal swings produced by biopotential or optical sensing front ends without needing a mid-supply bias rail. The 3.5 mV typical input offset translates to a small error term relative to the millivolt-level signals typical in these designs. Use the shutdown input to disable the amplifier while the wearable is in idle or sleep state, and keep the exposed pad-free 8-SOIC footprint easy to route in dense flex-circuit layouts.
추천
Transimpedance Photodiode Preamplifier
The TLV2760CD is a natural choice for transimpedance amplification of photodiode or optical receiver currents because its input bias current of approximately 3 pA produces negligible error across the feedback resistor, and its rail-to-rail input stage accepts the tiny detector voltages at the virtual ground. With 500 kHz gain-bandwidth product, a 10 MΩ feedback resistor still supports useful bandwidth for moderate-speed light measurements. The rail-to-rail output lets the amplified current swing close to the 1.8 V to 3.6 V limits, maximizing usable dynamic range. Keep the feedback network short and guard the input trace against photodiode capacitance to avoid peaking.
추천
Low-Power Active Filter Stages
Active filter designs in low-voltage embedded systems often need several gain stages but cannot afford the current draw of a general-purpose amplifier family. The TLV2760CD provides 500 kHz gain-bandwidth product at about 20 µA per amplifier, so a multi-stage filter built from this part stays within a tight power envelope. Rail-to-rail inputs and outputs are essential for filter stages referenced to a single 1.8 V rail, since they remove the need for virtual-ground biasing that would otherwise consume headroom. Set component values with the manufacturer datasheet gain-bandwidth and noise figures, and keep the shutdown line asserted when the filtered path is not required.
추천
Industrial Process Sensing and Data Acquisition
In industrial process monitoring, the TLV2760CD can be used where a low-voltage sensor rail and long battery or loop-powered lifetimes are required. The 3.5 mV typical offset and 3 pA bias current keep the error budget small relative to the 4-20 mA and resistive-divider signals common in process instrumentation, while the 0 °C to 70 °C commercial grade of the TLV2760CD covers standard factory environments. Because the maximum recommended supply is 3.6 V, protection and regulation ahead of the amplifier must keep transients inside that limit. For wider temperature ranges, the TLV2760ID industrial grade offers the same footprint and function.
추천
Low-Voltage Buffering and Level Shifting
The TLV2760CD works well as a buffer or level shifter between a low-voltage sensor or logic domain and a downstream ADC or MCU input. Its rail-to-rail input stage accepts signals down to 0 V, and the rail-to-rail output can drive a 1.8 V or 3.3 V domain directly without headroom loss, which non-RR amplifiers cannot do on such tight rails. The approximately 20 µA quiescent current keeps the buffer from dominating the standby budget of an always-on device, and the shutdown input provides a clean way to isolate the buffer during reset or sleep states. Use the manufacturer datasheet output drive capability to confirm the load and capacitive limits for the target node.

설계 노트
The TLV2760CD is rated for a maximum recommended supply voltage of 3.6 V. If the amplifier sits behind a regulator that could transiently overshoot, add a clamp or series damping and keep rail noise below 3.6 V under worst-case line conditions. For cell-powered designs, note that the device is specified from 1.8 V and characterized at 1.8 V and 2.4 V, so operating below 1.8 V is outside the guaranteed performance window even though the family tolerates down to 0.9 V supply in some applications.
Because the input bias current is only about 3 pA, the input node is extremely sensitive to leakage from board contamination and to stray capacitance in high-gain transimpedance stages. Keep the inverting input trace short, remove flux residue around the pins, and avoid placing the shutdown pin trace adjacent to the input. Route the shutdown control away from fast-switching nodes so that coupling into the high-impedance input does not appear as output noise.
A frequent design error is assuming a general-purpose rail-to-rail amplifier can be used as a precision reference buffer: the 3.5 mV typical input offset of the TLV2760CD is far larger than a zero-drift part such as the OPA333, so any gain stage near the input of a high-resolution ADC will amplify that offset. Use the shutdown pin only after confirming its logic levels in the manufacturer datasheet, and tie it to a defined state rather than leaving it floating, since a floating high-impedance control pin can pick up noise.
When the TLV2760CD drives a capacitive load such as an ADC sample-and-hold input or a long cable, verify the capacitive load drive specification in the manufacturer datasheet before assuming stability. If the load is highly capacitive, add an isolation resistor between the amplifier output and the load to preserve phase margin. For gain stages above roughly 10, keep the feedback network compact and use low-capacitance, tight-layout components to minimize parasitic poles inside the 500 kHz bandwidth.
