Product details
Overview
TLV6741DCKR from Texas Instruments is a single-channel, rail-to-rail output CMOS operational amplifier optimized for precision low-noise signal conditioning in space-constrained applications. It delivers 10 MHz gain bandwidth, 3.5 nV/√Hz broadband voltage noise at 10 kHz, ±3 pA input bias current, 0.15 mV max offset voltage, and operates from 2.25 V to 5.5 V supply - enabling high-fidelity amplification in solid-state drives and professional audio preamplifier stages.
For engineers reviewing the TLV6741DCKR datasheet, TLV6741DCKR pinout, TLV6741DCKR application, or TLV6741DCKR equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for low-noise, rail-to-rail op amp selection in battery-powered and industrial sensing systems.
Technical Context
The TLV6741DCKR employs a unity-gain-stable CMOS input stage with integrated RFI/EMI rejection filtering (71 dB EMIRR at 2.4 GHz), no phase reversal under overdrive, and robust 2-kV HBM ESD protection. Its resistive open-loop output impedance enables stable operation into ≥100 pF capacitive loads without external compensation.
Designed for low-voltage operation down to 2.25 V (±1.125 V), it supports single-supply configurations with rail-to-rail output swing (≤10 mV from rails at 10 kΩ load) and maintains precision across –40°C to 125°C ambient temperature, making it suitable for automotive cabin electronics and industrial transducer interfaces where thermal stability and supply flexibility are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 10 MHz - supports stable closed-loop gain ≥10 at 1 MHz or ≥1 at 10 MHz for wideband sensor signal conditioning. |
| Voltage Noise Density | 3.5 nV/√Hz at 10 kHz - enables <1 µVpp integrated noise in 100 kHz bandwidth, critical for transimpedance and bridge amplifier circuits. |
| Input Bias Current | ±3 pA - allows use with high-impedance sources (e.g., piezoresistive sensors, photodiode feedback networks) without significant offset drift. |
| Offset Voltage | ±0.15 mV (max) - ensures ≤150 µV error in 1 V full-scale measurement, supporting 12-bit+ accuracy without trimming. |
| Supply Range | 2.25 V to 5.5 V - compatible with Li-ion (3.0–4.2 V), USB (5 V), and dual-cell alkaline (3 V) power rails without LDO dependency. |
| Quiescent Current | 890 µA per channel - balances performance and power in always-on wearables and portable instrumentation. |
| EMI Rejection | 71 dB at 2.4 GHz - suppresses RF interference from Bluetooth/Wi-Fi co-location in compact PCB layouts. |
Pinout & Package
The TLV6741DCKR is housed in a 5-pin SC70 (DCK) package measuring 1.25 mm × 2.00 mm, optimized for high-density PCBs and thermally constrained designs. Its small footprint and exposed pad-free construction simplify assembly and reduce parasitic capacitance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN+ | Noninverting input | High-impedance CMOS node accepting signals up to V– and (V+) – 1.2 V; requires guarding in high-Z applications. |
| 2: V– | Negative supply / ground | Reference for single-supply operation; must be connected directly to PCB ground plane for EMI immunity. |
| 3: IN– | Inverting input | Differential input node; matched to IN+ for common-mode rejection; sensitive to layout-induced imbalance. |
| 4: OUT | Amplifier output | Rail-to-rail capable output driving ≥10 kΩ loads within 10 mV of supply rails; stable into ≥100 pF capacitive loads. |
| 5: V+ | Positive supply | Maximum 5.5 V rating; decoupling capacitor (0.1 µF ceramic) required within 2 mm for PSRR >95 dB at 100 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 10 mV of V+ and V– at 10 kΩ load - preserves dynamic range in low-voltage 3.3 V or 2.5 V systems. |
| Low broadband noise | 3.5 nV/√Hz at 10 kHz - reduces integrated noise floor in 100 kHz bandwidth by 4× vs typical 10-MHz op amps. |
| Unity-gain stable | No external compensation required - simplifies design of gain-of-1 buffers, active filters, and I/V converters. |
| Integrated EMI filter | 71 dB rejection at 2.4 GHz - eliminates need for external ferrite beads or RC filters in wireless-adjacent layouts. |
| Robust ESD protection | ±3000 V HBM - withstands handling and board-level ESD events without latch-up or parameter shift. |
Applications
| Solid-State Drive Signal Conditioning | Professional Audio Preamplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA320SAIDBVR | Lower noise (1.8 nV/√Hz), higher IQ (1.6 mA), same SC70-5 package; no integrated EMI filter. | Better for ultra-low-noise audio or metrology; less robust in RF-dense environments without external filtering. | Choose when absolute lowest noise dominates over EMI immunity and quiescent power. |
| LMV791MMX/NOPB | Higher noise (6.5 nV/√Hz), lower GBW (17 MHz), same supply range; lacks EMI rejection spec. | Suitable for cost-sensitive general-purpose amplification but not precision sensor front-ends near RF sources. | Choose only if budget constraints outweigh noise, EMI, and thermal drift requirements. |
Compared with OPA320SAIDBVR and LMV791MMX/NOPB, TLV6741DCKR uniquely balances 3.5 nV/√Hz noise, 71 dB EMI rejection, and 890 µA IQ in a 1.25 mm × 2.00 mm SC70 package - making it optimal for space-constrained, RF-adjacent precision analog systems where all three parameters matter.

FAQ
What is the maximum capacitive load the TLV6741DCKR can drive without oscillation?
The TLV6741DCKR features a resistive open-loop output impedance that enables stable operation into ≥100 pF capacitive loads without external compensation. This is confirmed in the datasheet's "Typical Characteristics" section (Figure 7-58), where step response remains well-damped up to 100 pF with 20 pF parasitic capacitance included. For loads exceeding 100 pF, a series isolation resistor (≥10 Ω) is recommended to maintain phase margin above 55°.
Does the TLV6741DCKR support true single-supply operation with input common-mode voltage extending to the negative rail?
Yes, the TLV6741DCKR supports true single-supply operation: its input common-mode voltage range extends from V– to (V+) – 1.2 V, and the output swings rail-to-rail (within 10 mV of both rails). This allows direct interfacing with ground-referenced sensors and microcontroller ADCs operating from the same 2.25–5.5 V supply, as verified in Section 7.3 (Recommended Operating Conditions) and Figure 7-11 (VO vs I Sourcing/Sinking).
What is the typical THD+N performance of the TLV6741DCKR at audio frequencies?
The TLV6741DCKR achieves 0.00035% THD+N at 1 kHz with 1 VRMS output, 5.5 V supply, and 10 kΩ load (Section 7.6 Electrical Characteristics). This corresponds to –109 dBc distortion, validated in Figure 7-17 and Figure 7-18. The value holds across 20 Hz–20 kHz when gain = +1 and bandwidth is limited to 80 kHz, making it suitable for high-fidelity line-level and microphone preamp stages.
How does the TLV6741DCKR's EMI rejection compare to standard op amps, and what frequency bands does it cover?
The TLV6741DCKR provides 71 dB electro-magnetic interference rejection ratio (EMIRR) at 2.4 GHz, significantly exceeding typical op amps (<40 dB). It also maintains >51 dB EMIRR at 1 GHz (Section 7.6), covering Wi-Fi 2.4 GHz, Bluetooth, and cellular LTE bands. This is achieved via an integrated RFI/EMI rejection filter, eliminating need for external shielding or RC snubbers in compact layouts.
Is the TLV6741DCKR qualified for automotive applications, and what temperature range is it specified over?
The TLV6741DCKR is specified over –40°C to +125°C ambient temperature (Section 7.3) and features 2-kV HBM ESD protection (Section 7.2), meeting core requirements for under-hood and cabin electronics. While not AEC-Q200 certified, its extended temperature rating, robust ESD tolerance, and stable parametric performance across temperature make it suitable for non-safety-critical automotive subsystems like infotainment sensor interfaces and HVAC controls.
