Product details
Overview
TLV2342IPW from Texas Instruments is a dual-channel, low-voltage, high-speed LinCMOS™ operational amplifier optimized 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 (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 analog front-ends.
For engineers reviewing the TLV2342IPW datasheet, TLV2342IPW pinout, TLV2342IPW application, or TLV2342IPW equivalent, key selection criteria include its 3-V/5-V characterization, input voltage range below ground, low quiescent current (0.65–1.4 mA), ESD-protected inputs (2000 V HBM), and TSSOP-8 packaging with left-end tape-and-reel delivery (TLV2342IPWLE).
Technical Context
The TLV2342IPW implements a dual independent amplifier topology using Texas Instruments' silicon-gate LinCMOS process, enabling high input impedance (1012 Ω) and ultra-low input currents while maintaining ac performance comparable to BiFET op-amps. Its internal ESD protection circuitry meets MIL-PRF-38535 Method 3015.2 (2000 V HBM), and latch-up immunity is designed-in per JEDEC JESD78.
Each amplifier operates down to 2-V supply and is fully characterized at both 3 V and 5 V over temperature. The common-mode input range spans from VDD – 1 V down to the negative rail (GND), and output voltage swing includes the negative rail - critical for single-supply precision amplification in low-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - supports direct integration into 3.3-V and 5-V systems, plus emerging 2.5-V/2.7-V rails without level-shifting. |
| Unity-Gain Bandwidth | 790 kHz at 3 V - enables stable closed-loop gain up to ~10× at audio and low-MHz sensor frequencies. |
| Slew Rate | 2.1 V/µs at 3 V - sufficient for 100-kHz full-power sine waves at ±1-V output swing, suitable for active filters and transducer interfaces. |
| Input Offset Voltage | 0.6–1.1 mV (max) - ensures ≤1.1-mV dc error in precision gain stages without external trimming. |
| Input Bias Current | 0.6 pA typical at 25°C - minimizes voltage drop across high-impedance sources (e.g., pH electrodes, photodiode TIA feedback networks). |
| Common-Mode Input Range | Extends to VDD – 1 V and below GND - allows direct sensing of signals referenced to ground in single-supply configurations. |
| Output Voltage Swing | Includes negative rail (GND) - eliminates need for negative supply in level-shifting or comparator reference circuits. |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm × 1.1 mm max height, lead pitch 0.65 mm, left-end taped and reeled (TLV2342IPWLE).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Inverting amplifier output - drives loads up to ±30 mA; rail-to-rail swing enables full dynamic range utilization. |
| 2 | IN–1 | Inverting input - high-impedance node (1012 Ω); matched to IN+1 for optimal CMRR. |
| 3 | IN+1 | Noninverting input - accepts common-mode voltages from GND to VDD – 1 V at 25°C. |
| 4 | GND / VDD– | Negative supply terminal - serves as reference for both amplifiers; must be low-impedance for noise rejection. |
| 5 | VDD+ | Positive supply terminal - powers both amplifiers; decoupling capacitor required within 1 cm. |
| 6 | IN+2 | Noninverting input of second amplifier - electrically isolated from Channel 1; identical specs and layout symmetry. |
| 7 | IN–2 | Inverting input of second amplifier - matched pair with IN+2; supports differential or independent configurations. |
| 8 | OUT2 | Second amplifier output - independently usable; no crosstalk specification given, but layout isolation recommended. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings to GND and within 1 V of VDD, maximizing signal headroom in 3-V systems. |
| Single-supply operation | Functional from 2 V to 8 V with full spec compliance at 3 V and 5 V - reduces BOM count vs. split-supply alternatives. |
| Ultra-low input bias current | 0.6 pA typical at 25°C - preserves accuracy in high-Z sensor interfaces (e.g., piezoelectric, capacitive, electrochemical). |
| ESD protection | 2000 V HBM per MIL-PRF-38535 - improves robustness during PCB handling and system-level ESD events. |
| Designed-in latch-up immunity | Guaranteed per JEDEC JESD78 - prevents catastrophic failure under transient overvoltage or I/O fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Higher supply current (1.2 mA/channel typ.), lower unity-gain bandwidth (1.2 MHz), same TSSOP-8 package. | Better suited for higher-frequency filtering (>100 kHz) but consumes more power - less ideal for sub-10-µA sleep modes. | Select when bandwidth >1 MHz is required and supply current budget allows ≥1.2 mA/channel. |
| LMV358IDR | Lower slew rate (1 V/µs), wider offset voltage range (±3 mV max), no guaranteed 2-V operation - specified only down to 2.7 V. | Cost-optimized for non-critical consumer applications; not qualified for extended low-voltage operation or precision sensor front-ends. | Select for cost-sensitive designs where 2.7-V minimum supply and ±3-mV offset are acceptable. |
Compared with TLV2342IPW, TLV2372IDR trades lower power for higher speed, while LMV358IDR offers lower cost but sacrifices low-voltage operation, precision, and input impedance - making TLV2342IPW the preferred choice for battery-constrained, rail-to-rail, high-Z sensor interfaces.

FAQ
What is the minimum operating supply voltage for TLV2342IPW?
The TLV2342IPW operates down to 2 V across the full –40°C to 85°C temperature range. It is fully characterized and tested at both 3 V and 5 V, with all electrical specifications guaranteed at those voltages. Operation below 2 V is not supported and may result in undefined behavior or loss of rail-to-rail output capability.
Does TLV2342IPW support true rail-to-rail input?
No - TLV2342IPW supports rail-to-rail *output* swing (to GND and within 1 V of VDD), but its common-mode input voltage range extends *below* the negative rail (GND) and up to VDD – 1 V at 25°C. This allows inputs to reach GND but not the full positive rail, distinguishing it from full rail-to-rail input op-amps.
What is the maximum output current capability of TLV2342IPW?
The TLV2342IPW delivers ±30 mA short-circuit output current per channel. Continuous output current should be limited by thermal dissipation: in the TSSOP-8 (PW) package, maximum power dissipation is 525 mW at 25°C, derating by 4.2 mW/°C above that temperature. Sustained ±20 mA loads require careful PCB thermal design.
Is TLV2342IPW pin-compatible with other dual op-amps in TSSOP-8?
TLV2342IPW uses the industry-standard dual-op-amp TSSOP-8 pinout (pin 1 = OUT1, pin 2 = IN–1, ..., pin 8 = OUT2), matching devices like LMV358, TLV2372, and MCP6002. However, functional compatibility depends on supply range, input/output swing, and bias current - TLV2342IPW's 2-V operation and 0.6-pA bias current are not replicated by most pin-compatible alternatives.
How does the ESD protection in TLV2342IPW compare to standard op-amps?
TLV2342IPW incorporates internal ESD-protection circuitry rated to 2000 V HBM per MIL-PRF-38535 Method 3015.2 - exceeding the 2-kV minimum for Class 2 HBM and matching industrial-grade robustness. This exceeds typical unguarded op-amps (often <500 V HBM) and reduces need for external TVS diodes in board-level ESD protection schemes.
