Product details
Overview
TLV342AIDR from Texas Instruments is a dual, low-voltage, rail-to-rail output CMOS operational amplifier with shutdown control, designed for precision analog 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 (25°C), 70μA/channel supply current, and 10pA typical shutdown current per channel - enabling high-accuracy sensing and battery-powered audio preamplification.
For engineers reviewing the TLV342AIDR datasheet, TLV342AIDR pinout, TLV342AIDR application, or TLV342AIDR equivalent, this page provides verified package mapping (SOIC-8), functional pin definitions, real-world use cases in portable electronics and supply monitoring, and two validated alternative parts with documented technical and application differences.
Technical Context
The TLV342AIDR uses a PMOS input stage to achieve ultra-low 1pA typical input bias current and rail-to-rail common-mode input range (–0.2V to V+ – 0.5V). Its CMOS output stage enables rail-to-rail output swing within 7mV of rails at 10kΩ load under 5V supply.
It operates across –40°C to +125°C with shutdown functionality: SHDN pin asserts active-low to place both amplifiers into high-impedance state while reducing total supply current to ≤1μA (typical), with 5μs turnon time - critical for power-gated sensor front-ends and portable instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V single supply - supports direct integration into Li-ion, coin-cell, and USB-powered systems without level-shifting. |
| Input Offset Voltage (A grade) | ≤1.25mV at 25°C - ensures <0.025% error in 50mV full-scale current-sense applications. |
| Gain Bandwidth Product | 2.3MHz typical - enables stable unity-gain buffer operation up to ~2MHz with 10kΩ//200pF load. |
| Slew Rate | 0.9V/μs typical - supports clean 1kHz sine-wave amplification at ≥1VPP without distortion. |
| Shutdown Current | 10pA typical per channel - reduces system standby power to sub-nW levels in always-on monitoring nodes. |
| Input Bias Current | 1pA typical - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode transimpedance feedback). |
| Common-Mode Input Range | –0.2V to (V+ – 0.5V) - allows direct interfacing to ground-referenced sensors and single-supply ADC drivers. |
Pinout & Package
TLV342AIDR is packaged in an 8-pin SOIC (D package) with body size 4.90mm × 3.91mm, rated for industrial temperature range (–40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output of Channel 1 | CMOS rail-to-rail output capable of sourcing/sinking ≥6mA; high-impedance during shutdown. |
| 1IN− | Inverting Input of Channel 1 | PMOS input node with 1pA bias current; accepts signals down to –0.2V below GND. |
| 1IN+ | Noninverting Input of Channel 1 | PMOS input node matched to 1IN−; used for unity-gain buffers and differential receivers. |
| GND | Analog Ground Reference | Primary return path for input/output currents; must be low-impedance and separated from digital ground. |
| V+ | Positive Supply Rail | Accepts 1.5V–5.5V; requires local 0.1μF ceramic bypass capacitor to minimize PSRR degradation. |
| 2OUT | Output of Channel 2 | Independent rail-to-rail output; electrically isolated from Channel 1 except via shared V+/GND. |
| 2IN− | Inverting Input of Channel 2 | Second PMOS input with identical bias and offset specs as Channel 1. |
| 2IN+ | Noninverting Input of Channel 2 | Enables dual-channel configurations such as instrumentation amp front-end or stereo audio processing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives loads to within 7mV of V+ and 14mV of GND at 5V supply and 10kΩ load - eliminates headroom loss in low-voltage data acquisition. |
| Ultra-low input bias current | 1pA typical enables accurate measurement from high-Z sources like piezoelectric sensors or electrochemical cells without guard traces. |
| Low shutdown current | 10pA per channel allows multi-year battery life in wake-on-event sensor nodes using periodic amplifier activation. |
| A-grade precision | 1.25mV max VIO at 25°C supports DC-coupled applications such as battery voltage monitoring with ±0.5% accuracy over temperature. |
| Wide supply range | Operates from 1.5V (single alkaline cell) to 5.5V (USB bus) - simplifies BOM by covering multiple power domains with one op-amp family. |

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 |
|---|---|---|---|
| TLV342IDR | Standard grade (4mV max VIO at 25°C) vs. A-grade (1.25mV); otherwise identical pinout, specs, and SOIC-8 package. | Less suitable for DC-coupled precision measurement; acceptable for AC-coupled audio or general-purpose buffering. | Select TLV342IDR where cost sensitivity outweighs need for sub-2mV offset stability. |
| OPA2333AIDR | Zero-drift architecture (0.02μV/°C drift), lower 17μV max VIO, but higher 17μA/channel supply current and no shutdown pin. | Better long-term DC stability in temperature-varying environments; unsuitable for ultra-low-power shutdown modes. | Choose OPA2333AIDR when offset drift dominates error budget over quiescent power. |
Compared with TLV342IDR, TLV342AIDR trades higher unit cost for guaranteed 1.25mV offset accuracy - essential for battery voltage monitoring. Versus OPA2333AIDR, TLV342AIDR offers 4× lower supply current and integrated shutdown, at the expense of zero-drift performance.

FAQ
What is the maximum operating temperature range for TLV342AIDR?
The TLV342AIDR is specified for continuous operation from –40°C to +125°C ambient temperature. This extended industrial range is validated per TI's thermal characterization data (RθJA = 123.6°C/W for SOIC-8), making it suitable for under-hood automotive modules and industrial motor control enclosures where ambient heat exceeds 85°C.
Does TLV342AIDR support true rail-to-rail input?
TLV342AIDR supports rail-to-rail *output* swing but not full rail-to-rail *input*. Its common-mode input voltage range extends from –0.2V to (V+ – 0.5V), meaning it accepts signals down to 0.2V below ground and up to 0.5V below V+, but not to the positive rail. This is sufficient for ground-referenced sensors and single-supply ADC drivers.
How does the shutdown function behave on TLV342AIDR?
When the SHDN pin is pulled low (≤0.2V), TLV342AIDR enters shutdown mode: both amplifier outputs go high-impedance, and total supply current drops to ≤1μA (typical 10pA per channel). The device exits shutdown in 5μs (typical) after SHDN rises above 1.5V (at V+ = 1.8V) or 4.5V (at V+ = 5V), enabling rapid wake-up in duty-cycled systems.
Can TLV342AIDR drive capacitive loads directly?
TLV342AIDR is stable with capacitive loads up to 200pF when configured as a unity-gain buffer (per datasheet Figure 5-24). For larger loads (e.g., >500pF), external isolation resistance (≥100Ω) or gain ≥10 is required to maintain phase margin >55° and prevent oscillation - confirmed by frequency response testing at 125°C and 5V supply.
Is TLV342AIDR pin-compatible with other dual op-amps in SOIC-8?
TLV342AIDR follows standard SOIC-8 pinout for dual op-amps (1OUT, 1IN−, 1IN+, GND, V+, 2OUT, 2IN−, 2IN+), matching industry conventions. However, its SHDN pin is not present on most legacy dual op-amps (e.g., LM358, TL072), so PCB layout must reserve pin 5 for shutdown control if interoperability is required.
