Product details
Overview
TLV2342IP 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 over –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 (including negative rail), common-mode input range extending to VDD – 1 V, and ultra-low input bias current (0.6 pA typical at 25°C). It is used in portable sensor signal conditioning and battery-powered audio preamplifiers.
For engineers reviewing the TLV2342IP datasheet, TLV2342IP pinout, TLV2342IP application, or TLV2342IP equivalent, this page provides verified package mapping (8-pin PDIP), confirmed dual-opamp topology, validated electrical specs at both 3 V and 5 V, and real-world design context for low-power, high-AC-performance analog front-ends.
Technical Context
The TLV2342IP implements a dual independent amplifier core using Texas Instruments' silicon-gate LinCMOS™ process, enabling high input impedance (1012 Ω typical) and ultra-low input currents without compromising AC performance. Its internal ESD protection meets MIL-PRF-38535 Method 3015.2 (2000 V HBM), and latch-up immunity is built-in per design.
Each channel operates fully functional down to 2 V supply, with full characterization at 3 V and 5 V across temperature. The input stage supports common-mode voltages from ground to VDD – 1 V at 25°C, while the output drives to within ~120 mV of ground and ~1.75 V below VDD at 3 V (IOL/IOH = ±1 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - enables direct use with single-cell Li-ion (3.0–3.7 V), two-cell alkaline (2.4–3.2 V), or regulated 3.3 V/5 V rails. |
| Unity-Gain Bandwidth | 790 kHz at 3 V - supports stable closed-loop gain ≥10 up to ~80 kHz; sufficient for anti-aliasing filters and active sensor interfaces. |
| Slew Rate | 2.1 V/µs at 3 V - allows clean 1-VPP output at ≤330 kHz without distortion; critical for pulse amplification and fast-settling DAC buffers. |
| Input Offset Voltage | ≤11 mV over full temperature range - ensures ≤11 mV DC error in precision gain stages without trimming; typ. 0.6 mV at 25°C. |
| Input Bias Current | 0.6 pA typical at 25°C - minimizes voltage drop across high-Z sensor sources (e.g., piezoelectric, pH electrodes) and reduces leakage-induced drift. |
| Common-Mode Input Range | Extends to VDD – 1 V at 25°C - permits direct sensing of signals referenced to positive rail (e.g., high-side current sense with level-shifted feedback). |
| Output Voltage Swing | Includes negative rail, up to VDD – 1.25 V at 3 V (IO = ±1 mA) - supports true single-supply operation with ground-referenced loads and rail-to-rail DAC interfacing. |
Pinout & Package
TLV2342IP is housed in an 8-pin plastic DIP (P) package with through-hole mounting. Pin 1 is marked by a notch or dot; orientation follows standard IC top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives external load; capable of sourcing/sinking ±1 mA while maintaining rail-to-rail swing. |
| 2 | IN1– | Inverting input of Amp 1 - high-impedance node; requires matched trace lengths if used in high-frequency differential configurations. |
| 3 | IN1+ | Non-inverting input of Amp 1 - accepts common-mode voltages from GND to VDD – 1 V at 25°C. |
| 4 | GND / VDD– | Negative supply terminal - must be connected directly to system ground plane; serves as reference for both amplifiers. |
| 5 | VDD+ | Positive supply terminal - accepts 2–8 V DC; bypass capacitor (0.1 µF ceramic) required near pin for stability. |
| 6 | IN2+ | Non-inverting input of Amp 2 - electrically identical to Pin 3; independent of Amp 1 for dual-channel operation. |
| 7 | IN2– | Inverting input of Amp 2 - matches Pin 2 in performance; no crosstalk specified between channels. |
| 8 | OUT2 | Amplifier 2 output - fully independent output; shares same drive capability and voltage range as OUT1. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives to GND and within 1.25 V of VDD at 3 V (±1 mA), maximizing dynamic range in single-supply systems. |
| Ultra-low input bias current | 0.6 pA typical at 25°C - preserves signal integrity when interfacing with MΩ-range sensors (e.g., photodiode transimpedance amps). |
| Wide supply voltage range | Operates from 2 V to 8 V - eliminates need for separate LDOs in multi-battery or mixed-voltage designs. |
| High CMRR & PSRR | 65–78 dB CMRR and 70–95 dB PSRR - rejects noise from shared power rails and common-mode interference in noisy environments. |
| ESD-protected inputs | Rated to 2000 V HBM - reduces risk of field failure during PCB handling and assembly without external protection diodes. |
| Latch-up immunity | Designed-in immunity per JEDEC JESD78 - prevents catastrophic failure under transient overcurrent or voltage stress conditions. |
Applications
| Portable Medical Sensors | Battery-Powered Audio Preamps |

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 |
|---|---|---|---|
| TLV2372IP | Lower supply current (550 µA vs. 650 µA typ. at 3 V), but reduced slew rate (1.5 V/µs) and bandwidth (550 kHz). | Better suited for ultra-low-power sleep-mode amplification where speed is secondary to current draw. | Select TLV2372IP only when <100 µA supply reduction justifies 30% lower bandwidth and slower settling. |
| LMV358M/N | Higher input offset (3.5 mV max vs. 11 mV max), wider temp range (–40°C to 125°C), but no rail-to-rail output (VOL ≈ 75 mV min). | Preferred in automotive under-hood modules requiring extended temperature rating and moderate precision. | Choose LMV358M/N only when 125°C operation is mandatory and output swing above ground is acceptable. |
Compared with TLV2342IP, TLV2372IP trades bandwidth for lower quiescent current, while LMV358M/N sacrifices rail-to-rail output and input precision for extended temperature capability-neither is pin-compatible, and both require layout review for decoupling and thermal relief.

FAQ
What is the minimum supply voltage for reliable operation of the TLV2342IP?
The TLV2342IP is fully functional down to 2 V supply voltage and characterized across –40°C to 85°C at both 3 V and 5 V. At 2 V, key parameters such as slew rate and bandwidth decrease, but the device remains operational with rail-to-rail output and common-mode input range extending to ground. Always verify stability with appropriate bypassing per the datasheet layout guidelines for TLV2342IP.
Does the TLV2342IP support rail-to-rail input and output?
The TLV2342IP supports rail-to-rail output swing (to GND and within ~1.25 V of VDD at 3 V, ±1 mA), but its common-mode input range extends only to VDD – 1 V at 25°C-not full rail-to-rail input. Input voltages beyond this limit may cause phase reversal or increased distortion. For true rail-to-rail input, consider TI's TLV2462 or similar variants.
Can the TLV2342IP drive capacitive loads directly?
The TLV2342IP is not unity-gain stable with large capacitive loads. Driving >100 pF directly may cause peaking or oscillation. For loads >50 pF, add a series resistor (typically 10–100 Ω) between the output and capacitor, or use a dedicated buffer stage. Stability data in the TLV2342IP datasheet confirms phase margin drops below 45° at CL = 200 pF.
What is the maximum junction temperature for continuous operation of the TLV2342IP?
The absolute maximum junction temperature for TLV2342IP is 150°C. With its 8-pin PDIP package (derating factor 8.0 mW/°C above 25°C), the maximum continuous power dissipation at 85°C ambient is 520 mW. Thermal design must ensure junction temperature stays ≤150°C under worst-case VDD, output loading, and ambient conditions.
Is the TLV2342IP pin-compatible with other members of the TLV234x family?
Yes-the TLV2342IP (dual) shares identical 8-pin PDIP pinout with TLV2342ID (SOIC) and TLV2342IPWLE (TSSOP), and is functionally compatible with TLV2342Y (chip form). However, it is not pin-compatible with quad TLV2344 variants (14-pin packages) or with unrelated families like TLV27x or TLV246x due to differing pin assignments and internal architecture.
