Product details
Overview
TLV6742IDR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision low-noise signal conditioning in 1.7 V to 5.5 V systems. It delivers 10 MHz gain bandwidth, 3.5 nV/√Hz input voltage noise at 10 kHz, ±3 pA input bias current, and 0.15 mV typical input offset voltage - enabling high-fidelity amplification in transimpedance, audio preamp, and sensor front-end circuits.
For engineers reviewing the TLV6742IDR datasheet, TLV6742IDR pinout, TLV6742IDR application, or TLV6742IDR equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel pin functions, real-world application constraints (e.g., 1.7 V minimum supply, –40°C to 125°C operation), and validated alternative options with documented functional and interface differences.
Technical Context
The TLV6742IDR implements a unity-gain-stable CMOS input stage with integrated RFI/EMI rejection filtering and no phase reversal under overdrive. Its resistive open-loop output impedance enables stable driving of ≥100 pF capacitive loads without external compensation.
It operates across a wide supply range (1.7 V to 5.5 V) with rail-to-rail output swing and supports single-supply configurations where V– serves as ground reference. ESD robustness is rated at ±2000 V HBM, and EMIRR reaches 71 dB at 2.4 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise density | 3.5 nV/√Hz at 10 kHz - enables low-noise amplification of weak signals (e.g., photodiode outputs) without dominating system noise floor |
| Gain bandwidth | 10 MHz - supports stable closed-loop operation up to ~1 MHz at G = +10, suitable for fast-settling instrumentation |
| Input bias current | ±3 pA - allows use with high-impedance sources (>100 MΩ) such as piezoresistive sensors or pH electrodes |
| Offset voltage | ±0.15 mV typical - reduces DC error in precision gain stages, minimizing calibration burden in measurement systems |
| Supply range | 1.7 V to 5.5 V - enables direct interfacing with Li-ion, coin-cell, and 3.3 V/5 V logic domains without level-shifting |
| Output swing | Rail-to-rail - delivers full dynamic range into ADCs or downstream analog stages operating near supply rails |
| Quiescent current | 990 µA per channel - balances low-power operation with performance in battery-powered wearables and portable test gear |
Pinout & Package
TLV6742IDR is packaged in an 8-pin SOIC (D) body measuring 3.91 mm × 4.90 mm, with standard surface-mount footprint and thermal characteristics (RθJA = 131.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives load directly; rail-to-rail swing supports full-scale signal delivery to ADC inputs or filters |
| 2 | IN1– | Inverting input, channel 1 - accepts feedback network connection; high CMRR (≥87 dB) rejects common-mode interference |
| 3 | IN1+ | Noninverting input, channel 1 - interfaces with high-Z sensors; ±3 pA bias current minimizes loading error |
| 4 | V– | Negative supply or ground reference - serves as return path for both channels; must be low-impedance for stability |
| 5 | IN2+ | Noninverting input, channel 2 - independent input path enables dual-sensor monitoring or differential pair configuration |
| 6 | IN2– | Inverting input, channel 2 - supports matched feedback networks for consistent gain accuracy across both amplifiers |
| 7 | OUT2 | Amplifier 2 output - electrically isolated from OUT1; enables independent signal paths without crosstalk (130 dB channel separation) |
| 8 | V+ | Positive supply - powers both amplifiers; 1.7 V minimum enables operation from single Li-ion or regulated 1.8 V supplies |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers >99% of supply rail-to-rail swing at 10 kΩ load - preserves signal integrity when driving SAR ADCs or low-voltage logic |
| Low broadband noise | 3.5 nV/√Hz at 10 kHz - critical for transimpedance amplifiers converting picoamp photocurrents into clean voltage signals |
| Unity-gain stability | Stable with gain ≥1 and ≥100 pF capacitive load - eliminates need for external compensation in sensor interface PCB layouts |
| Robust EMIRR | 71 dB at 2.4 GHz - suppresses RF ingress from Wi-Fi/BT antennas in compact wearable or IoT end equipment |
| Wide temperature range | Specified from –40°C to 125°C - ensures reliable operation in automotive cabin modules, industrial motor drives, and outdoor instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Lower offset drift (±0.02 µV/°C) but higher noise (5.5 nV/√Hz); 36 µA IQ per channel vs 990 µA | Better for ultra-low-drift DC-coupled systems (e.g., medical ECG front ends); less suitable for wideband AC-coupled audio | Select OPA2333AIDR when sub-µV/°C drift dominates design requirements and bandwidth < 350 kHz suffices |
| LMV722IDR | Higher noise (14 nV/√Hz), lower GBW (1.5 MHz), wider offset range (±2.5 mV), but same SOIC-8 package | Cost-optimized for non-critical general-purpose amplification where noise and speed are secondary | Choose LMV722IDR only for legacy designs or cost-sensitive applications where 10 MHz bandwidth and 3.5 nV/√Hz noise are unnecessary |
Compared with OPA2333AIDR and LMV722IDR, TLV6742IDR uniquely balances 10 MHz bandwidth, 3.5 nV/√Hz noise, and 1.7 V operation - making it optimal for battery-powered, wideband precision systems requiring both speed and low-noise fidelity.

FAQ
What is the minimum supply voltage for TLV6742IDR?
The TLV6742IDR operates down to 1.7 V (V+ – V–), with guaranteed functionality across –40°C to 125°C at this voltage. Operation between 1.7 V and 1.8 V is recommended only for ambient temperatures from 0°C to 85°C per TI's SBOS817I specification. Below 1.7 V, the device may not meet datasheet performance limits, and TLV6742IDR is not characterized for sub-1.7 V operation.
Does TLV6742IDR support rail-to-rail input?
No, TLV6742IDR does not support rail-to-rail input. Its common-mode input voltage range extends from V– to (V+ – 1.2 V), meaning it cannot accept signals within 1.2 V of the positive rail. This limitation must be accounted for in single-supply designs where input signals approach V+, and TLV6742IDR requires appropriate level shifting or biasing to remain within its specified VCM window.
What is the thermal resistance (RθJA) of TLV6742IDR in SOIC-8 package?
The junction-to-ambient thermal resistance (RθJA) for TLV6742IDR in the SOIC-8 (D) package is 131.1°C/W, measured on a standard JEDEC 2S2P test board. This value assumes proper PCB copper pour and thermal vias under the package body. Exceeding power dissipation limits calculated using this RθJA may cause junction temperature to exceed 150°C, risking reliability degradation of TLV6742IDR.
Is TLV6742IDR pin-compatible with other dual op amps in SOIC-8?
TLV6742IDR uses the industry-standard dual op amp pinout (IN1–, IN1+, OUT1, V–, IN2+, IN2–, OUT2, V+) defined in TI's SBOS817I datasheet. It is pin-compatible with many generic dual op amps (e.g., LM741, TL072, OPA2340) sharing this configuration, but functional differences - such as supply range, noise, and output swing - require validation before drop-in replacement. TLV6742IDR is not pin-compatible with shutdown-enabled variants like TLV6742S.
What is the maximum capacitive load TLV6742IDR can drive stably?
TLV6742IDR is unity-gain stable and can drive ≥100 pF capacitive loads without external compensation, as confirmed by TI's characterization in Figure 7-58 of SBOS817I. For loads exceeding 100 pF, stability margin decreases; layout best practices (short traces, local decoupling, and optional series resistor at output) are recommended. TLV6742IDR's resistive open-loop output impedance contributes to this robust capacitive drive capability.
