Product details
Overview
TLV2334IPW 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, 0.38 V/µs slew rate (at 3 V), 10¹² Ω input impedance, and rail-to-rail output swing down to the negative rail - ideal for battery-powered sensor signal conditioning and portable instrumentation.
For engineers reviewing the TLV2334IPW datasheet, TLV2334IPW pinout, TLV2334IPW application, or TLV2334IPW equivalent, key selection criteria include its 320 µA per amplifier supply current at 3 V, 10 mV max input offset voltage, common-mode input range extending below ground, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2334IPW 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 sensor interfacing. Its input stage operates with common-mode voltage down to –0.2 V (at 3 V supply) and up to VDD – 1 V, while the output stage drives loads to within 115 mV of ground and 1.75 V of VDD at 3 V.
Designed for stable operation with capacitive loads up to 20 pF, the device exhibits 39° phase margin at unity gain (3 V, 25°C) and maintains functional performance across full temperature and supply ranges without requiring external compensation - supporting robust filter, transducer interface, and analog front-end designs in low-power embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434CDR | Higher supply current (1.2 mA per amp), rail-to-rail input/output, 2.2 MHz GBW - trades power for speed and input range. | Better suited for higher-bandwidth sensor interfaces (>100 kHz) where supply headroom permits increased quiescent draw. | Select TLV2434CDR when unity-gain bandwidth >500 kHz and rail-to-rail input are required; avoid if battery life is primary constraint. |
| LM324DR | Wider supply range (3–32 V), higher VIO (7 mV typ), no rail-to-rail output, 1.2 mA per amp - legacy bipolar design with lower input impedance. | Applicable in fixed-line industrial equipment with 12/24 V supplies where cost and availability outweigh low-voltage performance needs. | Choose LM324DR only for non-battery applications with ample supply voltage and relaxed precision requirements; verify input common-mode range compatibility. |
Compared with TLV2434CDR and LM324DR, the TLV2334IPW uniquely balances ultra-low power (320 µA/amp), LinCMOS™ input impedance (10¹² Ω), and true single-supply capability (2 V min) - making it optimal for compact, battery-operated analog signal chains where precision and efficiency coexist.

FAQ
What is the maximum operating supply voltage for the TLV2334IPW?
The TLV2334IPW supports a maximum supply voltage of 8 V across its full operating temperature range of –40°C to 85°C. Exceeding this limit risks permanent damage, as specified in the absolute maximum ratings table. At 5 V operation, the device delivers improved slew rate (0.43 V/µs) and unity-gain bandwidth (525 kHz) compared to 3 V operation, while maintaining full functionality and rail-to-rail output swing. Always observe derating guidelines for thermal dissipation in the PW package.
Does the TLV2334IPW support rail-to-rail input operation?
No, the TLV2334IPW does not support rail-to-rail input operation. Its common-mode input voltage range extends from –0.2 V (below ground) to VDD – 1 V at 3 V supply, and from –0.2 V to VDD – 1 V at 5 V supply. This means the inputs can go slightly below the negative rail but cannot reach the positive rail - unlike rail-to-rail input amplifiers. For applications requiring full input swing, consider alternatives such as the TLV2434CDR, which explicitly specifies rail-to-rail input capability.
What is the typical input bias current of the TLV2334IPW at 85°C?
The typical input bias current of the TLV2334IPW is 200 pA at 85°C and 5 V supply, as confirmed in the "TLV2334I electrical characteristics" table on page 8 of the datasheet. At 25°C, it is 0.6 pA - demonstrating the exponential increase with temperature inherent to CMOS input stages. This value remains well below 1 nA, preserving high-impedance interface integrity even at elevated temperatures, critical for sensor front-ends in automotive or industrial enclosures.
Can the TLV2334IPW drive a 100 kΩ load while maintaining specified AC performance?
Yes, the TLV2334IPW is fully characterized driving a 100 kΩ load, as evidenced by test conditions consistently specifying RL = 100 kΩ across slew rate, bandwidth, and phase margin measurements. At 25°C and 3 V supply, it achieves 300 kHz unity-gain bandwidth and 39° phase margin into 100 kΩ with 20 pF capacitive load. Output voltage swing remains within specification (VOH = 1.75 V, VOL = 115 mV), confirming stable operation under this standard load condition used throughout the datasheet.
Is the TLV2334IPW pin-compatible with other TSSOP-14 quad op-amps like the LM324TPW?
No, the TLV2334IPW is not pin-compatible with the LM324TPW or other generic TSSOP-14 quad op-amps. While both use the TSSOP-14 package, the pin assignments differ: TLV2334IPW follows TI's standard quad op-amp pinout (e.g., OUT A/IN– A/IN+ A/GND/IN+ B/IN– B/OUT B/VDD+/OUT C/IN– C/IN+ C/IN+ D/IN– D/OUT D), whereas LM324 variants use different channel ordering and power pin locations. PCB layout must be designed specifically for TLV2334IPW; substitution requires schematic and layout revision.
