Product details
Overview
TLV6741DCKT 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, and 0.15 mV typical offset voltage - enabling high-fidelity amplification in transimpedance and audio preamplifier circuits operating from 2.25 V to 5.5 V.
For engineers reviewing the TLV6741DCKT datasheet, TLV6741DCKT pinout, TLV6741DCKT application, or TLV6741DCKT equivalent, this page provides verified specifications, SC70-5 package layout, real-world use cases in solid-state drives and lab instrumentation, and two validated alternative op amps with documented functional and supply-range differences.
Technical Context
The TLV6741DCKT employs a unity-gain-stable CMOS input stage with integrated RFI/EMI rejection filtering (71 dB EMIRR at 2.4 GHz) and no phase reversal under overdrive. Its resistive open-loop output impedance enables stable operation with capacitive loads up to 100 pF without external compensation.
Designed for low-voltage precision, it operates down to 2.25 V (±1.125 V) while maintaining rail-to-rail output swing within 8–10 mV of each rail at 5.5 V and 10 kΩ load - critical for battery-powered wearables and sensor front-ends requiring wide dynamic range near supply rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA320SAIDBVR | Lower noise (1.8 nV/√Hz), higher IQ (1.8 mA), same SC70-5 package | Better for ultra-low-noise audio; less suitable for battery-critical wearables due to 2× higher current | Choose when noise dominates budget and supply headroom permits higher IQ |
| TLV9061IDCKR | Higher GBW (10.6 MHz), lower IQ (560 µA), but higher offset (0.3 mV) and noise (4.6 nV/√Hz) | Better for power-sensitive IoT nodes; less accurate for DC-critical bridge sensing | Choose when ultra-low power is mandatory and 0.15-mV offset is not required |
Compared with TLV6741DCKT, OPA320SAIDBVR trades 2× quiescent current for 2× lower noise, while TLV9061IDCKR cuts IQ by 37% but sacrifices 0.15 mV offset accuracy and adds 1.1 nV/√Hz noise - making TLV6741DCKT the optimal balance for precision, low-power, space-constrained designs.

FAQ
What is the maximum capacitive load the TLV6741DCKT can drive without oscillation?
The TLV6741DCKT is unity-gain stable and characterized to drive up to 100 pF with minimal peaking (<1 dB) when properly decoupled. For loads >50 pF, TI recommends adding a 10-Ω series resistor between the output and capacitive load to isolate the op amp's output impedance and maintain phase margin above 55° - a technique verified in Figure 7-58 of the SBOS817I datasheet. This ensures reliable operation in ADC driver and filter applications where stray capacitance is unavoidable.
Does the TLV6741DCKT support true single-supply operation with input common-mode range extending to V−?
Yes, the TLV6741DCKT supports true single-supply operation: its input common-mode voltage range extends from V− to (V+ − 1.2 V), allowing inputs to reach the negative rail. When V− = 0 V (ground), signals down to 0 V are valid - essential for interfacing with ground-referenced sensors like thermistors or resistive bridges. The rail-to-rail output complements this, swinging within 8 mV of 0 V at 5.5 V supply and 10-kΩ load.
How does the TLV6741DCKT's EMI rejection performance compare to standard op amps in 2.4-GHz environments?
The TLV6741DCKT delivers 71 dB electro-magnetic interference rejection ratio (EMIRR) at 2.4 GHz - significantly exceeding typical general-purpose op amps (40–55 dB). This is achieved via an integrated on-die RFI/EMI rejection filter, which prevents RF rectification that causes DC offset shifts or audible noise in nearby Wi-Fi/Bluetooth systems. In wearable or IoT designs co-located with 2.4-GHz radios, this eliminates the need for external ferrite beads or RC filters.
What is the guaranteed offset voltage specification for TLV6741DCKT over temperature?
The TLV6741DCKT has a guaranteed maximum input offset voltage of ±1.0 mV over the full –40°C to +125°C operating range, with ±0.15 mV typical at 25°C. Its low ±0.2 µV/°C drift ensures total offset variation remains below ±0.17 mV across a 100°C span - critical for DC-coupled applications like pressure transmitter front-ends where thermal drift directly impacts measurement accuracy.
Can the TLV6741DCKT be used in transimpedance amplifier configurations with photodiodes?
Yes, the TLV6741DCKT is well-suited for transimpedance amplifiers: its ±3 pA input bias current minimizes dark-current error in high-impedance photodiode circuits, and its 10-MHz gain bandwidth supports >1-MHz signal bandwidths with feedback resistors up to 1 MΩ. The unity-gain stability and low 3.5 nV/√Hz noise preserve signal integrity - confirmed in TI's Application Report SBAA347 for optical sensor interfaces.
