Product details
Overview
TLV342SIRUGR from Texas Instruments is a dual, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for precision signal conditioning in 1.5V–5.5V single-supply systems. It delivers 2.3MHz gain bandwidth, 0.9V/μs slew rate, 1.25mV max input offset (A grade), 70μA/channel quiescent current, and 10pA typical shutdown current per channel - enabling high-accuracy battery monitoring and audio preamplification in space-constrained portable electronics.
For engineers reviewing the TLV342SIRUGR datasheet, TLV342SIRUGR pinout, TLV342SIRUGR application, or TLV342SIRUGR equivalent, key selection criteria include its X2QFN-10 package footprint, dual-channel shutdown control timing (5μs turnon), rail-to-rail output swing within 7mV of rails at 10kΩ load, and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The TLV342SIRUGR integrates two independent CMOS op-amps with PMOS input stages delivering 1pA typical input bias current and rail-to-rail output swing enabled by complementary CMOS output transistors. Its input common-mode range extends from –0.2V to (V+ – 0.5V), supporting ground-referenced sensing in low-voltage systems.
Shutdown functionality is implemented via an active-low SHDN pin that places both amplifiers into high-impedance output state while reducing total supply current to 10pA typical per channel. The device maintains stable unity-gain performance with ≥55° phase margin under 200pF capacitive load and supports operation down to 1.5V supply without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - enables direct integration into Li-ion, coin-cell, and USB-powered systems without level-shifting. |
| Gain Bandwidth Product | 2.3MHz (typ) - supports stable closed-loop gain up to ~20× at 100kHz for sensor signal amplification. |
| Input Offset Voltage | 1.25mV max (25°C, A grade) - ensures ≤0.1% error in 12-bit ADC front-end applications with ±1V input range. |
| Slew Rate | 0.9V/μs (typ) - allows faithful reproduction of 100kHz full-scale sine waves with <1% distortion. |
| Shutdown Current | 10pA typical per channel - reduces system standby power to sub-nW levels in battery-critical applications. |
| Input Bias Current | 1pA typical - minimizes voltage error across high-impedance sources (e.g., pH sensors, photodiodes). |
| Common-Mode Input Range | –0.2V to (V+ – 0.5V) - permits direct interface with ground-referenced transducers and single-ended DAC outputs. |
Pinout & Package
The TLV342SIRUGR is housed in a 10-pin X2QFN package (1.5mm × 2.0mm, 0.5mm pitch) with wettable flanks for automated optical inspection. Thermal resistance is RθJA = 158.3°C/W, supporting operation at full spec in compact PCB layouts without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting input, Channel 1 | Accepts analog signals down to –0.2V; high-impedance node requiring guarded routing. |
| 2 (GND) | Analog ground reference | Primary return path for both channels; must connect to low-noise analog ground plane. |
| 3 (SHDN) | Active-low shutdown control | Pull to GND disables both amplifiers; pull to V+ (≥1.5V) enables normal operation. |
| 4 (IN+) | Noninverting input, Channel 2 | Independent input for second signal path; shares same electrical specs as Pin 1. |
| 5 (IN−) | Inverting input, Channel 2 | Used for inverting configurations; matched offset and bias with Pin 4. |
| 6 (OUT) | Output, Channel 2 | Rail-to-rail capable; drives loads ≥2kΩ without clipping at 1.8V supply. |
| 7 (V+) | Positive supply rail | Accepts 1.5V–5.5V; requires local 0.1μF ceramic bypass capacitor to GND. |
| 8 (NC) | No internal connection | Not bonded; must remain unconnected and unpopulated on PCB. |
| 9 (OUT) | Output, Channel 1 | Electrically identical to Pin 6; supports dual independent signal paths. |
| 10 (IN−) | Inverting input, Channel 1 | Matches Pin 5 in performance; enables differential or inverting gain configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV342DR | SOIC-8 package; no shutdown pin; 200μA/channel supply current; same A-grade offset spec. | Lacks power-gating capability; unsuitable for ultra-low-power intermittent sensing. | Select when board space allows SOIC and continuous operation is required. |

FAQ
What is the maximum operating temperature range for TLV342SIRUGR?
The TLV342SIRUGR is specified for continuous operation from –40°C to +125°C ambient temperature. This extended industrial range is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and gain bandwidth, making it suitable for under-hood automotive modules and outdoor industrial sensors where thermal stress is critical.
Does TLV342SIRUGR support true rail-to-rail input?
The TLV342SIRUGR supports rail-to-rail *output* swing but has a limited input common-mode range extending from –0.2V to (V+ – 0.5V). While it accepts signals down to 0.2V below ground, it does not reach the positive rail - unlike some newer amplifiers. For applications requiring full rail-to-rail input, consider TI's OPA333 or similar chopper-stabilized alternatives.
How does the shutdown function behave electrically in TLV342SIRUGR?
When the SHDN pin is pulled low (≤0.2V), both amplifiers enter shutdown mode: output pins go to high impedance, supply current drops to 10pA typical per channel, and internal bias circuitry is disabled. The output remains floating - no internal clamping or pull-down - so external termination may be needed in high-impedance nodes to prevent noise coupling.
Can TLV342SIRUGR drive capacitive loads reliably?
Yes - the TLV342SIRUGR maintains stability with up to 200pF capacitive load at unity gain, achieving ≥55° phase margin per datasheet testing. For loads exceeding 200pF, a small series resistor (10–50Ω) between amplifier output and capacitor is recommended to isolate reactive feedback and preserve step response fidelity.
Is TLV342SIRUGR pin-compatible with other TLV342 variants?
No - the TLV342SIRUGR uses a 10-pin X2QFN package with dedicated SHDN and NC pins, whereas TLV342DR (SOIC-8) and TLV342DGK (VSSOP-8) have different pin counts and assignments. The SHDN pin (Pin 3) and NC pin (Pin 8) in TLV342SIRUGR have no counterpart in 8-pin variants, requiring PCB redesign for substitution.
