TLV9061IDCKR 개요
An operational amplifier (op amp) is a high-gain DC-coupled differential amplifier that uses external feedback to set its closed-loop transfer function. Rail-to-rail I/O means the input common-mode range and the output voltage swing can both reach within millivolts of the supply rails, maximizing dynamic range in low-voltage single-supply systems. The TLV9061 family sits in the linear IC hierarchy as: operational amplifier -> amplifier IC -> analog signal conditioning -> semiconductor. Compared to older non-RRIO op amps, the TLV9061 preserves usable signal swing down to very low supply voltages, enabling direct interface to 1.8 V MCUs and sensors.
Key features include 10 MHz gain-bandwidth product, 6.5 V/µs slew rate, 0.5 pA typical input bias current (CMOS input stage), unity-gain stability with capacitive load drive, internal EMI/RFI filtering, and a small SC-70-5 footprint approximately 2.0 mm × 1.25 mm. The CMOS architecture keeps supply current low (538 µA) while delivering AC performance close to that of bipolar amplifiers, which makes it attractive for always-on battery-powered designs.
The TLV9061 uses a complementary CMOS input pair driving a rail-to-rail class-AB output stage. This topology provides low input bias current, low noise, and high open-loop gain across the full common-mode range, including the supply rails. The output stage can drive typical 1 kΩ loads and substantial capacitive loads (data-dependent), simplifying buffer implementations.
Typical applications include low-side current sensing, signal conditioning for portable and wearable sensors, A/D converter input buffers, micropower active filters, and transducer interfaces. Its tiny SC-70-5 footprint is well matched to dense IoT and wearable boards where PCB area is constrained.
When designing with this device, place a 0.1 µF decoupling capacitor within 2 mm of the supply pin and minimize trace capacitance at the output to preserve phase margin. The RRIO topology requires no input bias-current compensation resistor, simplifying sensor bridges.

일반적인 애플리케이션
TLV9061IDCKR 적합 용도: 6 애플리케이션s: Low-Side Current Sensing, Wearable and Portable Sensor Signal Conditioning, ADC Input Driver / Buffer, Active Filters (Sallen-Key, Multiple-Feedback), Transducer and Bridge Amplifier, General-Purpose Signal Buffering and Gain Stages.
Low-Side Current Sensing
The TLV9061IDCKR is well-suited to low-side current-sensing in battery-powered and portable designs, where its 1.8-5.5 V supply range directly interfaces with 1S Li-ion or 3.3 V rails. Its rail-to-rail input common-mode range allows the sense amplifier to operate with input voltages near ground, while the 0.5 pA input bias current minimizes the error introduced by high-value shunt resistors (often 100 mΩ to 1 Ω). The 10 MHz gain-bandwidth product enables accurate amplification of fast current transients during PWM load steps, supporting closed-loop monitoring in motor control and power-path management. The CMOS input stage draws negligible current from the shunt, preserving measurement accuracy.

Wearable and Portable Sensor Signal Conditioning
In wearable health monitors and portable IoT nodes, the TLV9061IDCKR's tiny SOT-SC70-5 footprint (2.0×1.25 mm) leaves board area for additional sensors or a smaller battery. Its 538 µA quiescent current extends battery runtime while still delivering the 10 MHz bandwidth needed to condition photodiode, accelerometer, or biometric signals. The rail-to-rail output maximizes ADC dynamic range on low-voltage rails, and the CMOS input stage's 0.5 pA bias current preserves signal integrity from high-impedance sensor sources. Internal RFI/EMI filtering improves immunity to nearby radio transceivers in connected wearables.
추천
ADC Input Driver / Buffer
The TLV9061IDCKR serves as a low-voltage buffer for successive-approximation register (SAR) ADCs, where its unity-gain stability and rail-to-rail output allow it to drive the ADC's input network directly without oscillation. The 10 MHz bandwidth settles the buffer output well within typical ADC acquisition windows, even when driving the ADC's switched-capacitor kickback. Designers benefit from the low 10 nV/√Hz noise floor which does not degrade the ADC's effective number of bits (ENOB) at low gains. The 1.8-5.5 V supply aligns with modern low-power SAR ADCs operating from the same rail.

Active Filters (Sallen-Key, Multiple-Feedback)
Active low-pass, high-pass, and band-pass filters up to several hundred kHz can be built around the TLV9061IDCKR with predictable response. The 10 MHz gain-bandwidth product leaves ample loop gain at cutoff frequencies up to 200 kHz, supporting high-order Sallen-Key or multiple-feedback topologies with minimal gain error. The 6.5 V/µs slew rate preserves filter linearity for audio-band signals, and the rail-to-rail input/output allows filter designs that use the full supply range. Designers can implement low-cost anti-aliasing or reconstruction filters without the need for higher-speed specialty op amps.
추천
Transducer and Bridge Amplifier
The TLV9061IDCKR's 0.5 pA input bias current and CMOS input make it ideal for amplifying signals from high-impedance transducers such as piezoelectric sensors, photodiodes, and strain-gauge bridges. The low input bias current does not load the source, preserving the small signal levels produced by these sensors. The 1.8 V minimum supply allows direct interfacing with low-voltage transducers, and the rail-to-rail input accepts common-mode voltages within millivolts of either rail for bridge circuits biased near the supply edges.
추천
General-Purpose Signal Buffering and Gain Stages
In cost-sensitive consumer electronics, the TLV9061IDCKR provides a versatile building block for inverting, non-inverting, and differential gain stages. Its 1.8-5.5 V supply, 10 MHz GBW, and 538 µA quiescent current offer a balanced trade-off between performance and power for products such as toys, appliance user interfaces, and low-cost instrumentation. Designers can stock a single part type across multiple gain configurations and use the internal RFI/EMI filtering to meet industrial ESD/EMI requirements without external components.

설계 노트
Place a 0.1 µF X7R ceramic decoupling capacitor within 2 mm of the V+ pin (pin 4), with the ground return directly to the V- pin (pin 2) to minimize supply-loop inductance. For multi-amplifier boards, add a 1 µF to 10 µF bulk capacitor per supply rail. The 538 µA quiescent current per channel should be budgeted against total battery life in always-on designs.
Keep the IN+ (pin 3) and IN- (pin 5) traces short and symmetric, and route them away from noisy digital lines to minimize parasitic coupling. The SOT-SC70-5 footprint has no thermal pad, so the primary heat-dissipation path is the V+ and V- pins. Use a continuous ground plane beneath the device to provide low-impedance return paths and to maintain the unity-gain stability claimed in the TI datasheet.
Do not exceed the absolute maximum supply voltage of 6 V (per TI datasheet). Avoid driving capacitive loads larger than the datasheet-specified limit without an isolation resistor, as exceeding this can destabilize the output stage. For shutdown variants (TLV9051S), the SHDN pin must not be left floating - tie it to V+ if unused. Do not apply input voltages beyond the supply rails; the CMOS input stage includes ESD clamp diodes that will forward-bias and inject current if overdriven.
