Product details
Overview
TLV2342ID from Texas Instruments is a dual-channel, low-voltage, high-speed operational amplifier in the LinCMOS™ family, designed for single-supply operation from 2 V to 8 V across –40°C to 85°C. It delivers 2.1 V/µs slew rate and 790 kHz unity-gain bandwidth at 3 V, features rail-to-rail output swing down to the negative rail, and supports common-mode input voltage extending below ground - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2342ID datasheet, TLV2342ID pinout, TLV2342ID application, or TLV2342ID equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-opamp circuit role, temperature-stable ac performance data at 3 V/5 V, ESD-protected input stage specifications, and validated alternatives for low-voltage analog front-end redesign.
Technical Context
The TLV2342ID implements a dual independent op-amp topology using silicon-gate LinCMOS™ process technology, achieving ultra-low input bias current (0.6 pA typical at 25°C) and high input impedance (10¹² Ω). Its internal architecture supports full functionality down to 2 V supply while maintaining characterized performance at both 3 V and 5 V over industrial temperature range.
Each channel features common-mode input range from VDD–/GND to VDD –1 V at 25°C, rail-inclusive output stage capable of driving loads to GND, and integrated ESD protection rated to 2000 V per MIL-PRF-38535 Method 3015.2 - making it suitable for direct interface with transducers and ADC drivers in space-constrained, low-power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - enables operation from single-cell Li-ion (3.0–3.7 V) or two alkaline cells (2.4–3.2 V) without regulation. |
| Slew Rate (3 V) | 2.1 V/µs - supports >100 kHz small-signal amplification with minimal distortion in active filters. |
| Unity-Gain Bandwidth (3 V) | 790 kHz - sufficient for anti-aliasing, sensor gain stages, and audio pre-amplification up to ~100 kHz. |
| Input Offset Voltage (max) | 9 mV - ensures ≤0.9% gain error in 1 V full-scale 12-bit ADC interface applications. |
| Input Bias Current (typ) | 0.6 pA at 25°C - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor circuits. |
| Common-Mode Input Range | Extends to VDD–/GND and up to VDD –1 V - allows direct sensing of signals referenced to ground in single-supply systems. |
| ESD Rating | 2000 V HBM - reduces need for external protection in handheld medical or industrial data loggers. |
Pinout & Package
TLV2342ID is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, D suffix, with standard 1.27 mm pitch and 3.91 mm × 4.90 mm body dimensions. The device is available taped and reeled (TLV2342IDR).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Channel 1 output | Drives load directly to GND or up to VDD –1 V; rail-to-rail capable with 30 mA short-circuit tolerance. |
| 2 (1IN–) | Channel 1 inverting input | High-impedance node (10¹² Ω); accepts differential inputs down to –0.2 V at 3 V supply. |
| 3 (1IN+) | Channel 1 non-inverting input | Same high-Z and voltage range as 1IN–; supports single-ended or differential configurations. |
| 4 (VDD–/GND) | Negative supply / ground reference | Return path for both channels; common reference for input and output stages. |
| 5 (VDD) | Positive supply | Single power rail (2–8 V); powers both op-amps and internal bias circuitry. |
| 6 (2IN+) | Channel 2 non-inverting input | Independent high-Z input identical to 1IN+; enables dual-path signal processing. |
| 7 (2IN–) | Channel 2 inverting input | Independent high-Z input identical to 1IN–; supports separate feedback networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher quiescent current (550 µA/channel vs. 650 µA typ), wider VIO range (2 mV max), lower noise (11 nV/√Hz), but slower slew rate (0.5 V/µs). | Better dc precision and noise, but unsuitable for >100 kHz signal paths requiring fast settling. | Select TLV2462IDR when dc accuracy dominates over ac performance; avoid for active filter or wideband sensor apps. |
| OPA2340UA | Rail-to-rail I/O, lower VIO (1.5 mV max), higher GBW (5.5 MHz), but higher supply current (800 µA/channel) and narrower temp range (–40°C to 125°C). | Superior bandwidth and precision, but consumes >2× supply current and lacks 2-V min supply capability. | Choose OPA2340UA only when >1 MHz bandwidth is required and 3 V supply is guaranteed; not viable for 2.4 V alkaline systems. |
Compared with TLV2342ID, TLV2462IDR trades ac speed for improved dc stability and noise floor, while OPA2340UA delivers significantly higher bandwidth at the cost of minimum supply voltage compliance and power efficiency - making TLV2342ID uniquely balanced for 2–5 V, <1 MHz, low-quiescent applications.

FAQ
What is the minimum supply voltage for reliable operation of TLV2342ID?
The TLV2342ID operates reliably down to 2 V supply voltage across the full –40°C to 85°C temperature range. At 2 V, it maintains functional amplification, though slew rate and bandwidth decrease versus 3 V or 5 V operation. Electrical characteristics are fully specified at 3 V and 5 V, with guaranteed functionality confirmed at 2 V per absolute maximum ratings and recommended operating conditions tables in the SLOS194 datasheet.
Does TLV2342ID support true rail-to-rail input operation?
The TLV2342ID does not support rail-to-rail input - its common-mode input voltage range extends from VDD–/GND to VDD –1 V at 25°C (e.g., –0.2 V to 1.8 V at 3 V supply). However, it does provide rail-to-rail output swing, driving to GND and within 1 V of VDD. This asymmetric input range is intentional for single-supply optimization and avoids the trade-offs of full rail-to-rail input architectures.
Can TLV2342ID drive capacitive loads directly?
The TLV2342ID is not unity-gain stable with large capacitive loads; stability must be verified per application. The datasheet specifies phase margin of 49° at 25°C with CL = 20 pF and RL = 10 kΩ. For loads >100 pF, external isolation resistance (e.g., 10–100 Ω in series with output) or feedback network compensation is recommended to prevent peaking or oscillation, especially in high-impedance sensor buffer configurations.
What is the thermal performance of TLV2342ID in SOIC-8 package?
In the SOIC-8 (D) package, TLV2342ID has a thermal resistance θJA of 162°C/W and a maximum power dissipation of 725 mW at TA ≤ 25°C, derating linearly by 5.8 mW/°C above that temperature. At 85°C ambient and 3 V supply, total IDD ≈ 1.4 mA per channel yields ~4.2 mW dissipation - well within safe limits, allowing operation without heatsinking in standard PCB layouts with 2 oz copper.
Is TLV2342ID pin-compatible with other dual op-amps in SOIC-8?
TLV2342ID uses the industry-standard dual-op-amp SOIC-8 pinout (1OUT, 1IN–, 1IN+, GND, VDD, 2IN+, 2IN–, 2OUT), matching LM2904, TLV2462, and OPA2340. However, electrical behavior differs significantly - especially input bias current (0.6 pA vs. 45 nA for LM2904) and supply voltage range (2–8 V vs. 3–36 V). Pin compatibility exists mechanically and topologically, but functional substitution requires full circuit validation.
