Product details
Overview
TLV2334IPWR from Texas Instruments is a quad low-voltage, medium-power operational amplifier in LinCMOS™ technology, designed for single-supply operation from 2 V to 8 V across –40°C to 85°C. It delivers 300 kHz unity-gain bandwidth and 0.38 V/µs slew rate at 3 V, with rail-to-rail output swing down to the negative rail and common-mode input range extending below ground - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2334IPWR datasheet, TLV2334IPWR pinout, TLV2334IPWR application, or TLV2334IPWR equivalent, key selection criteria include its 320 µA per-amplifier supply current at 3 V, 10 mV max input offset voltage, 10¹² Ω input impedance, ESD-protected inputs (2000 V HBM), and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2334IPWR integrates four independent amplifiers on a single die using Texas Instruments' silicon-gate LinCMOS™ process, enabling ultra-low input bias currents (0.6 pA typ at 25°C) and high input impedance critical for high-impedance source interfacing. Its internal architecture supports stable operation with capacitive loads up to 20 pF and features built-in latch-up immunity and ESD protection circuitry compliant with MIL-STD-883C Method 3015.2.
It operates fully functional at minimum 2-V supply and is characterized at both 3 V and 5 V, with common-mode input range specified from –0.2 V to VDD–1 V at 25°C and output swing guaranteed to within 190 mV of the negative rail and 300 mV of the positive rail under 1-mA load - making it suitable for true single-supply signal acquisition without level-shifting circuitry.
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 | 300 kHz at 3 V - sufficient for anti-aliasing, sensor amplification, and active filtering up to audio-band frequencies. |
| Slew Rate | 0.38 V/µs at 3 V - supports clean step response for 10-bit ADC driving and moderate-speed control loops. |
| Input Offset Voltage | 10 mV max over temperature - ensures ≤0.5% gain error in unity-gain buffer or 100× gain stages with DC-coupled inputs. |
| Supply Current per Amp | 320 µA typ at 3 V, 1200 µA max over temperature - balances performance and battery life in always-on monitoring nodes. |
| Input Impedance | 10¹² Ω typ - preserves signal integrity when buffering piezoelectric sensors, pH electrodes, or high-Q filter networks. |
| ESD Rating | 2000 V HBM - reduces need for external protection in handheld or field-deployable equipment. |

TSSOP-14 (PW) package: 5.0 mm × 6.4 mm × 1.1 mm body, 0.65 mm pitch, lead-free, RoHS-compliant surface-mount outline optimized for automated assembly and thermal performance in dense layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output | Amplifier outputs capable of sourcing/sinking ±1 mA while maintaining rail-to-rail swing; drive 100-kΩ loads directly. |
| 2, 6, 10, 14 | Inverting Input | Differential input node with 0.6 pA bias current - minimizes offset drift in high-impedance feedback networks. |
| 3, 7, 11, 12 | Non-inverting Input | High-Z input accepting signals from –0.2 V to VDD–1 V at 25°C - supports ground-referenced or negative-biased transducer outputs. |
| 4 | Negative Supply / Ground | Common return for all four amplifiers; internally tied to substrate; accepts 0 V reference or split-negative rail. |
| 8 | Positive Supply | Single power rail connection supporting 2–8 V; decoupling capacitor required within 1 cm for stability. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434IDR | Higher supply current (1.2 mA/amp), rail-to-rail I/O, 2.2 MHz GBW - trades power for speed and input/output swing. | Better suited for higher-frequency active filters or fast-settling data acquisition where 300 kHz is insufficient. | Select TLV2434IDR only if bandwidth >1 MHz and full rail-to-rail input are required; TLV2334IPWR remains optimal for microamp-level power budgets. |
| MCP6004-E/ST | Lower supply current (1 µA/amp), 1 MHz GBW, but only 0.6 V/µs slew rate and no guaranteed VIO spec over temperature. | Preferred for ultra-low-power wake-on-event systems where bandwidth is secondary to standby current. | Choose MCP6004-E/ST for sub-µA always-on sensing; TLV2334IPWR provides superior AC performance and tighter DC specs for precision analog chains. |
Compared with TLV2434IDR and MCP6004-E/ST, the TLV2334IPWR uniquely balances 300 kHz bandwidth, 0.38 V/µs slew rate, and 320 µA supply current - delivering verified DC accuracy and stability in 2–8 V single-supply industrial and medical signal paths where both speed and efficiency matter.

FAQ
What is the maximum operating temperature range for the TLV2334IPWR?
The TLV2334IPWR is rated for continuous operation from –40°C to +85°C ambient temperature, with all electrical specifications guaranteed across this full industrial temperature range. This makes it suitable for deployment in outdoor environmental sensors, automotive cabin modules, and factory-floor instrumentation where thermal extremes are expected. The device's LinCMOS™ process ensures stable input offset voltage and bias current behavior throughout this range.
Does the TLV2334IPWR support true single-supply operation with inputs below ground?
Yes, the TLV2334IPWR supports true single-supply operation with its common-mode input voltage range extending to –0.2 V at 3 V supply (and –0.2 V to VDD–1 V at 25°C). This allows direct connection of grounded-referenced transducers like current-sense resistors or thermocouples without external level-shifting circuitry. The input stage is designed to remain linear and functional even when one input is slightly negative relative to the negative supply pin (Pin 4).
What is the typical input bias current of the TLV2334IPWR and why does it matter?
The TLV2334IPWR has a typical input bias current of 0.6 pA at 25°C, enabled by its LinCMOS™ silicon-gate process. This ultra-low value prevents loading errors in high-impedance circuits such as pH probes, photodiode transimpedance amplifiers, or high-value RC filter networks. For example, with a 100-MΩ feedback resistor, this bias current contributes only ~0.06 mV of offset - preserving accuracy in precision measurement applications where TLV2334IPWR is commonly deployed.
Can the TLV2334IPWR drive capacitive loads, and what is the recommended compensation?
The TLV2334IPWR is characterized for stable operation with up to 20 pF capacitive load when driving 100-kΩ loads, as confirmed in its datasheet Figures 34–36. For heavier capacitive loads (e.g., >50 pF), TI recommends adding a small isolation resistor (10–50 Ω) in series with the output to maintain phase margin above 36°. No external compensation capacitor is required for standard PCB traces or typical ADC input capacitance, simplifying layout in compact sensor modules where TLV2334IPWR is used.
Is the TLV2334IPWR pin-compatible with other TSSOP-14 quad op-amps like the LM324 or MCP6004?
No, the TLV2334IPWR is not pin-compatible with LM324 or MCP6004 in TSSOP-14 packages. Its pinout follows TI's standard quad op-amp arrangement (outputs on Pins 1/5/9/13, inverting inputs on Pins 2/6/10/14, non-inverting inputs on Pins 3/7/11/12, V– on Pin 4, V+ on Pin 8), whereas LM324 uses different assignments (e.g., V+ on Pin 4, V– on Pin 11). Always verify pin mapping against the TLV2334IPWR datasheet before PCB layout - incorrect assumptions may cause functional failure or damage.
