Product details
Overview
TLV6742SIRUGR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for low-noise precision signal conditioning in space-constrained applications. It delivers 3.5 nV/√Hz input voltage noise, 10-MHz gain bandwidth, ±3 pA input bias current, and operates from 1.7 V to 5.5 V supply - enabling high-fidelity amplification in wearables, test instrumentation, and transimpedance circuits.
For engineers reviewing the TLV6742SIRUGR datasheet, TLV6742SIRUGR pinout, TLV6742SIRUGR application, or TLV6742SIRUGR equivalent, this page provides verified package mapping (10-pin X2QFN), confirmed shutdown functionality per channel, exact thermal metrics (RθJA = 140.3°C/W), and validated alternative options for dual-channel low-noise op amp selection.
Technical Context
The TLV6742SIRUGR implements a unity-gain-stable CMOS input stage with integrated RFI/EMI rejection filtering, delivering robust 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.
Each channel features independent active-low shutdown pins (SHDN1/SHDN2), reducing quiescent current from 990 µA/ch to ≤3.5 µA/ch when disabled. The device is specified across –40°C to +125°C and supports single-supply operation down to 1.7 V with rail-to-rail output swing within 5 mV of each rail at 10-kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise density | 3.5 nV/√Hz at 10 kHz - enables low-noise amplification of microvolt-level sensor signals without significant SNR degradation |
| Gain bandwidth | 10 MHz - supports stable closed-loop gain ≥10 at 1 MHz or unity gain up to 10 MHz for wideband signal paths |
| Input bias current | ±3 pA - permits use with high-impedance sources (e.g., photodiodes, piezoelectric sensors) without measurable offset error |
| Supply range | 1.7 V to 5.5 V - allows direct interfacing with Li-ion, coin-cell, or 3.3-V/5-V systems without level-shifting |
| Offset voltage drift | ±0.2 µV/°C - ensures <0.1 mV total drift over full –40°C to +125°C range, critical for uncalibrated industrial sensing |
| Shutdown current | ≤3.5 µA per channel - reduces system standby power by >99% versus active mode, essential for battery-operated devices |
| EMIRR | 71 dB at 2.4 GHz - suppresses RF interference from Wi-Fi/Bluetooth antennas without external filtering |
Pinout & Package
The TLV6742SIRUGR is housed in a 10-pin X2QFN package (RUG) measuring 1.5 mm × 2.0 mm with an exposed thermal pad connected to V– for enhanced thermal performance (RθJA = 140.3°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V– | Negative supply / ground reference | Must be connected to system ground or lowest supply rail; thermal pad tied here for optimal heat dissipation |
| SHDN1 | Channel 1 enable control | Active-low logic input; drives channel 1 into ultra-low-power state (<3.5 µA) when pulled low |
| SHDN2 | Channel 2 enable control | Independent active-low logic input; enables selective power gating of second amplifier |
| IN2+ | Noninverting input, channel 2 | Differential pair input with ±3 pA bias current - suitable for high-Z sensor interfaces |
| IN2– | Inverting input, channel 2 | Paired with IN2+; supports standard op-amp configurations including transimpedance and difference amplifiers |
| OUT2 | Output, channel 2 | Rail-to-rail swing within 5 mV of rails at 10-kΩ load - preserves dynamic range in low-voltage systems |
| V+ | Positive supply | Accepts 1.7–5.5 V; internal regulation ensures consistent performance across supply range |
| OUT1 | Output, channel 1 | Electrically isolated from OUT2; supports dual-path signal processing without crosstalk (130 dB channel separation) |
| IN1– | Inverting input, channel 1 | Matches IN2– characteristics; enables matched dual-channel designs such as instrumentation amps |
| IN1+ | Noninverting input, channel 1 | Matches IN2+ characteristics; maintains identical noise and offset behavior between channels |
Key Features
| Feature | Design Value |
|---|---|
| Integrated EMI filter | 71-dB rejection at 2.4 GHz eliminates need for external ferrite beads or RC filters in noisy environments |
| Independent shutdown | Dual SHDN pins allow per-channel power control - critical for adaptive power management in multi-sensor nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2376AIDR | Lower noise (2.8 nV/√Hz), higher IQ (760 µA/ch), no shutdown pins, SOIC-8 only | Better SNR for ultra-low-level signals; unsuitable where per-channel power gating is required | Choose OPA2376AIDR when absolute minimum noise dominates over power control and package size |
| ADA4807-2ARMZ | Higher bandwidth (225 MHz), higher noise (4.9 nV/√Hz), no shutdown, MSOP-8, ±2.5-V min supply | Optimized for high-speed data acquisition; not viable for 1.7–1.8-V battery-powered systems | Choose ADA4807-2ARMZ when bandwidth >100 MHz is mandatory and supply voltage ≥±2.5 V is available |

FAQ
What is the minimum supply voltage supported by TLV6742SIRUGR?
The TLV6742SIRUGR operates from 1.7 V to 5.5 V. Operation at 1.7 V is specified for ambient temperatures between 0°C and 85°C; full –40°C to +125°C operation requires ≥1.8 V supply. This enables direct integration with single-cell Li-ion and alkaline battery systems without voltage boosting.
Does TLV6742SIRUGR include independent shutdown control for each amplifier channel?
Yes, TLV6742SIRUGR features two dedicated active-low shutdown pins: SHDN1 controls channel 1 and SHDN2 controls channel 2. When either pin is pulled low, its respective amplifier enters ultra-low-power mode (<3.5 µA total supply current), while the other channel remains fully operational - enabling flexible power management in dual-signal-path designs.
What is the thermal resistance (RθJA) of TLV6742SIRUGR in its X2QFN package?
The TLV6742SIRUGR in the 10-pin X2QFN (RUG) package has a junction-to-ambient thermal resistance (RθJA) of 140.3°C/W, measured per JEDEC JESD51-7 standard. This value assumes standard 2-layer PCB layout with 1-in² copper pour under the thermal pad connected to V–, enabling reliable operation at up to 125°C ambient when dissipating ≤35 mW per channel.
How does the EMIRR performance of TLV6742SIRUGR benefit system-level design?
TLV6742SIRUGR achieves 71 dB EMIRR at 2.4 GHz - significantly exceeding typical op amps (40–55 dB). This suppresses RF rectification artifacts caused by nearby Wi-Fi/Bluetooth transceivers, eliminating audible buzz in audio systems and measurement errors in sensitive instrumentation without requiring external EMI filters or shielded enclosures.
Is TLV6742SIRUGR unity-gain stable and what does that mean for circuit design?
Yes, TLV6742SIRUGR is unity-gain stable. This means it can be configured as a voltage follower (gain = +1) without external compensation components, ensuring stable step response and preventing oscillation. Designers avoid adding stability resistors or capacitors, reducing board area, BOM cost, and tuning effort - especially valuable in high-density layouts.
