Product details
Overview
TLV2334ING4 from Texas Instruments is a quad low-voltage, medium-power operational amplifier designed for single-supply operation down to 2 V. It delivers 300 kHz unity-gain bandwidth and 0.38 V/µs slew rate at 3 V, with rail-to-rail output swing and input common-mode range extending below ground. It serves in battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TLV2334ING4 datasheet, TLV2334ING4 pinout, TLV2334ING4 application, or TLV2334ING4 equivalent, key selection criteria include its 10 mV max input offset voltage at –40°C to 85°C, 1.2 mA total supply current (300 µA per amplifier), LinCMOS™ high-input-impedance architecture (10¹² Ω), and compatibility with 3 V/5 V systems requiring low quiescent power without sacrificing AC performance.
Technical Context
The TLV2334ING4 implements a silicon-gate LinCMOS™ process enabling ultra-low input bias current (0.6 pA typ at 25°C) and high common-mode rejection (65 dB min over temperature). Its input stage operates with rail-to-rail common-mode range (–0.2 V to VDD–1 V at 25°C) and output stage swings to within 115 mV of ground and 1.7 V of VDD at 1 mA load.
Designed for stable operation with capacitive loads up to 20 pF, it maintains ≥36° phase margin across –40°C to 85°C and supports unity-gain configurations without external compensation. The device incorporates ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2) and latch-up immunity per JEDEC JESD78.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2334IDR | Same die, SOIC-14 package with tape-and-reel delivery; 0.65 mm pitch vs. DIP's 2.54 mm. | Requires surface-mount PCB assembly; unsuitable for prototyping breadboards or through-hole production. | Select TLV2334IDR for automated SMT lines where board space and reflow compatibility are priorities. |
| LMV334DR | Lower VIO (7 mV max), higher supply current (170 µA per amp), no guaranteed 2 V operation. | Better DC precision but incompatible with sub-2.7 V battery systems; lacks LinCMOS™ input stage robustness. | Choose LMV334DR only if VIO < 7 mV is mandatory and supply remains ≥2.7 V throughout system lifetime. |
Compared with TLV2334ING4, TLV2334IDR offers identical electrical performance in a space-saving SOIC package ideal for volume production, while LMV334DR trades ultra-low voltage capability for tighter offset-making TLV2334ING4 the sole choice for 2–3 V battery-powered instrumentation requiring guaranteed rail-to-rail input and proven ESD resilience.

FAQ
What is the maximum operating temperature range for TLV2334ING4?
The TLV2334ING4 is fully specified and tested over an operating free-air temperature range of –40°C to +85°C. All key parameters-including input offset voltage, supply current, and unity-gain bandwidth-are guaranteed across this range. Absolute maximum junction temperature is 150°C, and storage temperature extends from –65°C to +150°C per the official datasheet.
Does TLV2334ING4 support true single-supply operation with inputs below ground?
Yes, TLV2334ING4 supports true single-supply operation with its input common-mode voltage range extending to –0.2 V (below ground) at 25°C and –0.2 V over the full –40°C to 85°C range. This allows direct interfacing with transducers whose outputs swing slightly negative relative to system ground-eliminating the need for external level-shifting circuitry in TLV2334ING4-based designs.
What is the typical supply current per amplifier in TLV2334ING4 at 3 V?
At VDD = 3 V and TA = 25°C, the typical supply current per amplifier in TLV2334ING4 is 320 µA. Across the full temperature range (–40°C to 85°C) and with no load, the maximum total supply current for all four amplifiers is 1600 µA (400 µA per amplifier), making TLV2334ING4 suitable for always-on, low-duty-cycle sensor nodes.
Can TLV2334ING4 drive capacitive loads without instability?
TLV2334ING4 is characterized for stable operation with capacitive loads up to 20 pF when driving a 100 kΩ load, as verified in Figures 34–36 of the datasheet. For loads exceeding 20 pF, a series isolation resistor (typically 10–50 Ω) between the output and capacitance is recommended to maintain ≥36° phase margin and prevent peaking or oscillation in TLV2334ING4 circuits.
Is TLV2334ING4 pin-compatible with other packages in the TLV2334 family?
No-TLV2334ING4 uses a 14-pin plastic DIP (N) package with 0.300-inch width and through-hole leads, while TLV2334ID uses SOIC-14 and TLV2334IPWLE uses TSSOP-14. Pin numbering and physical dimensions differ significantly; PCB layout and footprint must be redesigned when switching packages. TLV2334ING4 is not a drop-in replacement for surface-mount variants.
