Product details
Overview
TLV342AID from Texas Instruments is a dual, low-voltage, rail-to-rail output CMOS operational amplifier with shutdown functionality, designed for precision analog signal conditioning in space-constrained, battery-powered systems. It delivers 2.3MHz gain bandwidth, 0.9V/μs slew rate, and 1.25mV max input offset voltage (25°C, A grade) while operating from 1.5V to 5.5V supply. It is used in portable audio preamplifiers and battery monitoring circuits where ultra-low quiescent current (70μA/channel) and shutdown mode (10pA typical) are critical.
For engineers reviewing the TLV342AID datasheet, TLV342AID pinout, TLV342AID application, or TLV342AID equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel pin functions, real-world design meaning of rail-to-rail swing and PMOS input stage, and two validated alternative parts with documented functional and application differences.
Technical Context
The TLV342AID implements a dual-channel architecture with independent PMOS input stages enabling ultra-low input bias current (1pA typical) and common-mode input range extending to ground and up to V+ – 0.5V. Its CMOS output stage supports rail-to-rail swing with <25mV headroom at 10kΩ load under 1.8V operation.
It features an active-low SHDN pin that places both amplifiers into high-impedance output state with 10pA typical shutdown current and 5μs typical turnon time. The device is specified across –40°C to +125°C and supports single-supply operation down to 1.5V, making it suitable for direct-coupled sensor interfaces and low-voltage portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - enables direct integration into Li-ion (3.0–4.2V), coin-cell (1.5–3.0V), and 3.3V/5V systems without level shifting |
| Input Offset Voltage (A grade) | 1.25mV max at 25°C - ensures ≤0.025% error in 5V full-scale DC-coupled measurement paths |
| Gain Bandwidth Product | 2.3MHz typical - supports stable unity-gain buffer operation up to ~2MHz with 10kΩ//200pF load |
| Slew Rate | 0.9V/μs typical - limits large-signal settling time to <2.2μs for 2V step (10%–90%) |
| Rail-to-Rail Output Swing | ≤20mV from rails (10kΩ, 1.8V) - preserves dynamic range in low-voltage ADC driver applications |
| Shutdown Current | 10pA typical per channel - reduces system standby power by >99.9% vs active mode (70μA) |
| Input Bias Current | 1pA typical - minimizes voltage error across high-impedance sources (e.g., pH sensors, photodiodes) |
Pinout & Package
TLV342AID is packaged in an 8-pin SOIC (D package) with 4.90mm × 3.91mm body size and standard 1.27mm pitch. Pin 1 is marked by a beveled corner or dot.
| 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; accepts common-mode voltages from GND to V+ − 0.5V |
| 1IN+ | Noninverting Input of Channel 1 | PMOS input node; matched to 1IN− for low offset and drift |
| GND | Analog Ground Reference | Return path for input bias current and output load; must be low-impedance for noise immunity |
| V+ | Positive Supply Rail | Single supply input (1.5–5.5V); powers both channels and internal bias circuitry |
| 2OUT | Output of Channel 2 | Independent rail-to-rail output; electrically isolated from 1OUT except via shared V+/GND |
| 2IN− | Inverting Input of Channel 2 | Second PMOS input; fully differential pair with 2IN+ for matched performance |
| 2IN+ | Noninverting Input of Channel 2 | Second PMOS input; identical electrical characteristics to 1IN+ and 1IN− |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 1pA typical enables use with >1GΩ source impedances without significant DC error |
| A-grade precision offset | 1.25mV max at 25°C allows direct-coupled sensor front-ends without trimming |
| Rail-to-rail output swing | 20mV headroom at 10kΩ load maximizes usable voltage range in 1.8V/3.3V systems |
| Active-low shutdown control | Reduces total supply current to 10pA typical and isolates outputs for power-gated subsystems |
| Extended temperature range | –40°C to +125°C operation supports automotive cabin, industrial motor control, and outdoor IoT nodes |

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 | Same silicon, SOIC-8 package, but standard grade (4mV max VIO at 25°C) and no A-grade screening | Lacks guaranteed low-offset performance for precision DC-coupled measurement paths | Select when cost sensitivity outweighs need for ≤1.25mV offset; otherwise TLV342AID preferred for accuracy-critical roles |
| OPA2313AIDR | Higher 10MHz GBW, lower 12nV/√Hz noise, but 100μA/channel ICC and no shutdown pin | Not suitable for ultra-low-power shutdown modes; better for higher-speed signal chains with less stringent current budget | Choose when bandwidth >2.3MHz or noise <20nV/√Hz is required and shutdown is unnecessary |
Compared with TLV342IDR, TLV342AID delivers tighter offset control for precision sensing; compared with OPA2313AIDR, it trades bandwidth and noise for 30% lower supply current and integrated shutdown-making it optimal for always-on, battery-limited applications requiring long-term stability.

FAQ
What is the maximum supply voltage rating for TLV342AID?
The absolute maximum supply voltage for TLV342AID is 5.5V. Operation above this level risks permanent damage. Recommended operating range is 1.5V to 5.5V, with full specification compliance across this span. At 5V supply, the device delivers 2.3MHz GBW, 1V/μs slew rate, and 1.7mV max offset over –40°C to +125°C.
Does TLV342AID support true rail-to-rail input?
No, TLV342AID does not support rail-to-rail input. Its common-mode input voltage range extends from –0.2V to (V+ – 0.5V), meaning it accepts inputs down to ground but only up to 0.5V below the positive rail. This PMOS-input architecture enables ultra-low input bias current (1pA typical) but excludes the top 0.5V of the supply range.
How does the shutdown function behave on TLV342AID?
TLV342AID's SHDN pin is active-low. When pulled to GND, both amplifiers enter shutdown mode with 10pA typical supply current per channel and high-impedance outputs. Turnon time from shutdown is 5μs typical. During shutdown, the output remains in high-impedance state-no clamping or leakage path is enabled.
What is the thermal resistance (RθJA) of TLV342AID in SOIC-8 package?
The junction-to-ambient thermal resistance (RθJA) for TLV342AID in the SOIC-8 (D) package is 123.6°C/W, as specified in the TI datasheet SLVS568E. This value assumes standard JEDEC 2-layer board conditions and is critical for calculating maximum allowable power dissipation at elevated ambient temperatures.
Is TLV342AID pin-compatible with other dual op-amps in SOIC-8?
TLV342AID follows the industry-standard dual op-amp SOIC-8 pinout (1OUT, 1IN−, 1IN+, GND, V+, 2OUT, 2IN−, 2IN+), matching devices like LM358, TLV2372, and OPA2313. However, functional compatibility requires verification of input stage type (PMOS vs bipolar), shutdown presence, and supply range-TLV342AID's PMOS input and shutdown pin are not replicated in most legacy SOIC-8 dual op-amps.
