Product details

Overview

TLV2334IDR 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 TLV2334IDR datasheet, TLV2334IDR pinout, TLV2334IDR application, or TLV2334IDR equivalent, key selection considerations include its 10 mV max input offset voltage at full temperature range, microamp-level supply current (1.2 mA typical total for all four amplifiers at 5 V), common-mode input range extending below ground, and compatibility with space-constrained PCB layouts using the SOIC-14 package.

Technical Context

The TLV2334IDR employs Texas Instruments' silicon-gate LinCMOS™ process to achieve ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance, enabling direct interfacing with high-impedance sources like piezoelectric sensors and RC filter networks. Its internal ESD protection withstands 2000 V (MIL-STD-883C, Method 3015.2) and latch-up immunity supports robust operation in noisy industrial environments.

Each of the four independent amplifiers features rail-inclusive common-mode input range (down to VDD–/GND and up to VDD –1 V at 25°C), output stage capable of driving ±30 mA, and stable unity-gain operation with 39° phase margin (at 3 V, 25°C). The device is fully characterized at both 3 V and 5 V supplies, supporting design flexibility across low-voltage embedded systems.

Key Specifications

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), wider VIO range (2.5 mV max), rail-to-rail I/O, but only specified down to 2.7 V min supply.	Better DC precision and full rail-to-rail I/O, but incompatible with 2 V or 3 V-only systems.	Select TLV2434CDR when higher speed (1.5 MHz GBW) and tighter offset are required, and supply ≥2.7 V is guaranteed.
LMV324IDR	Lower cost, 1 MHz GBW, 2.7–5.5 V supply range, 7 mV VIO max, but input range does not extend below GND and bias current is 100× higher (60 pA).	Acceptable for non-critical DC-coupled apps where ground-referenced inputs suffice and power budget allows ~250 µA extra per amp.	Choose LMV324IDR for cost-sensitive consumer electronics where ultra-low bias current and sub-ground input capability are not required.

Compared with TLV2334IDR, TLV2434CDR offers superior precision and full rail-to-rail I/O but sacrifices 2 V operation and increases quiescent power; LMV324IDR provides higher bandwidth at lower cost but lacks ground-swing input capability and exhibits significantly higher input bias current - making TLV2334IDR uniquely suited for ultra-low-power, ground-referenced sensor front-ends.

FAQ

What is the minimum supply voltage for reliable operation of the TLV2334IDR?

The TLV2334IDR operates reliably down to 2 V across its full rated temperature range of –40°C to 85°C. It is fully characterized and tested at both 3 V and 5 V, and functional operation is guaranteed at 2 V - making it suitable for single-cell lithium or two-cell alkaline battery systems where voltage sags below 2.5 V occur during discharge.

Does the TLV2334IDR support true rail-to-rail input operation?

The TLV2334IDR supports rail-inclusive common-mode input voltage range: inputs can swing from VDD–/GND up to VDD –1 V at 25°C (and to VDD –1.2 V at 85°C per characterization). While not rail-to-rail on the positive side, its ability to accept signals at ground potential without phase reversal or increased distortion makes it ideal for single-supply sensor interfaces where the negative rail is GND.

What is the maximum output current capability of each amplifier in the TLV2334IDR?

Each amplifier in the TLV2334IDR can source or sink up to ±30 mA continuously, as specified in the Absolute Maximum Ratings table. This drive strength supports direct interfacing with moderate-impedance loads such as LED drivers, small relays, or ADC input buffers without external transistors - though thermal limits (377 mW at 85°C in SOIC-14) require attention when operating near current limits at elevated ambient temperatures.

How does the input offset voltage of the TLV2334IDR vary with temperature?

The TLV2334IDR has an average temperature coefficient of input offset voltage (αVIO) of 1 µV/°C typical, with a maximum of 1.7 µV/°C over 25°C to 85°C. At full temperature range (–40°C to 85°C), the maximum input offset voltage is specified as 12 mV - a value derived from initial offset plus drift accumulation, ensuring predictable DC error in precision gain stages without calibration.

Is the TLV2334IDR pin-compatible with other quad op-amps in SOIC-14 packages?

The TLV2334IDR uses the industry-standard SOIC-14 pinout for quad op-amps (pin 1 = Ch1 out, pin 4 = GND, pin 8 = VDD, pin 14 = Ch4 out), matching LM324, TLV2434, and LMV324 families. However, differences in input stage architecture, supply range, and output swing mean that while physical layout is compatible, electrical substitution requires verification of common-mode range, output loading, and supply voltage constraints in the target application.
