Product details
Overview
TLV2344IPWR from Texas Instruments is a quad, low-voltage, high-speed operational amplifier in the LinCMOS™ family, designed 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, with rail-to-rail output swing and input common-mode range extending to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2344IPWR datasheet, TLV2344IPWR pinout, TLV2344IPWR application, or TLV2344IPWR equivalent, key selection criteria include its 1.3 mA typical supply current at 3 V, 10 mV max input offset voltage, ultra-low 0.1 pA input bias current, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2344IPWR employs silicon-gate LinCMOS™ process technology to achieve high input impedance (10¹² Ω typical), ultra-low input bias currents, and ac performance approaching BiFET op-amps - while operating from low single supplies. Its internal ESD protection withstands 2000 V (MIL-PRF-38535, Method 3015.2) and latch-up immunity is built-in.
Each of the four amplifiers features independent input stage design allowing common-mode voltage operation down to the negative rail and up to VDD – 1 V at 25°C, with output swing including the negative rail. The device is fully characterized at both 3 V and 5 V over full temperature range, supporting robust design in portable medical devices and industrial data acquisition systems.
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 | 790 kHz at 3 V - supports stable closed-loop gain ≥10 for audio preamp and anti-aliasing filter applications up to ~70 kHz. |
| Slew Rate | 2.1 V/µs at 3 V - allows clean 100-kHz, 1-Vpp sine wave output without distortion in active filter stages. |
| Input Offset Voltage | 10 mV max (–40°C to 85°C) - sets worst-case dc error floor in precision transimpedance or differential sensing circuits. |
| Input Bias Current | 0.6 pA typical at 25°C - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode feedback networks). |
| Common-Mode Input Range | Extends to negative rail and up to VDD – 1 V - permits direct interfacing with ground-referenced sensors and single-supply ADC drivers. |
| Output Voltage Swing | Includes negative rail - enables true zero-output capability in level-shifting and comparator hysteresis circuits. |
Pinout & Package
TSSOP-14 (PW) package: 5.0 mm × 6.4 mm × 1.1 mm height, lead pitch 0.65 mm, RoHS-compliant, left-end tape-and-reel (TLV2344IPWLE designation). Designed for automated SMT assembly and thermal performance up to 700 mW at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (–) | High-impedance node for feedback network connection; accepts signals down to GND. |
| 2, 6, 10, 14 | Non-inverting Input (+) | High-Z input accepting common-mode voltages from GND to VDD – 1 V. |
| 3, 7, 11, 12 | Output | Rail-to-rail output capable of sourcing/sinking ±30 mA; swings to GND under load. |
| 4 | VDD+ | Positive supply terminal; decoupling capacitor required within 1 cm for stability. |
| 8 | VDD–/GND | Ground reference for all amplifiers; shared return path requires low-impedance layout. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Functional from 2 V to 8 V - eliminates need for dual-rail supplies in portable equipment. |
| Rail-to-rail output | Drives loads to GND and within 1 V of VDD - maximizes dynamic range in 3.3 V systems. |
| Ultra-low input bias current | 0.6 pA typical - preserves signal integrity in high-Z sensor front-ends (e.g., piezoelectric, capacitive). |
| ESD protection | 2000 V HBM rating - reduces risk of field failure during handling and board assembly. |
| Latch-up immunity | Designed-in per JEDEC JESD78 - ensures reliability under transient overvoltage or reverse-bias conditions. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2444IPWR | Higher 2.5 V/µs slew rate, 2.2 MHz GBW, but 1.25 mA higher IDD at 3 V; input offset voltage tighter (max 4 mV). | Better for higher-frequency active filters (>200 kHz); less suitable for ultra-low-power (<10 µA sleep mode) designs. | Choose TLV2444IPWR when bandwidth and precision outweigh quiescent current constraints. |
| LMV324IPWR | Lower 1 V/µs slew rate, 1 MHz GBW, 0.8 mA IDD at 3 V; rail-to-rail output only (not input); no ESD rating specified. | Cost-optimized for non-critical consumer applications; unsuitable for high-Z sensor interfaces due to 10 nA input bias current. | Choose LMV324IPWR for cost-sensitive, moderate-performance applications where input bias current >1 nA is acceptable. |
Compared with TLV2444IPWR and LMV324IPWR, the TLV2344IPWR offers the optimal balance of low supply current (1.3 mA), ultra-low input bias (0.6 pA), and proven ESD robustness - making it uniquely suited for precision, battery-constrained analog signal chains where sensor fidelity and long runtime are co-prioritized.

FAQ
What is the maximum operating temperature range for the TLV2344IPWR?
The TLV2344IPWR 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, slew rate, and supply current - are guaranteed across this range per the SLOS194 datasheet. This makes TLV2344IPWR suitable for industrial and automotive cabin applications where ambient temperatures vary widely.
Does the TLV2344IPWR support true rail-to-rail input operation?
The TLV2344IPWR supports rail-to-rail *output* swing and extends its common-mode input voltage range *to the negative rail* (GND) and up to VDD – 1 V at 25°C. However, it does not provide full rail-to-rail input (i.e., it cannot accept signals equal to VDD). This asymmetric input range is optimized for single-supply sensor interfaces where the signal stays near GND or mid-supply.
Can the TLV2344IPWR drive capacitive loads directly?
The TLV2344IPWR is stable with capacitive loads up to 20 pF when driving into a 10 kΩ load, as verified in the datasheet's Figure 34 and 36. For larger capacitive loads (e.g., >50 pF), external isolation resistance (e.g., 100 Ω in series with the output) is recommended to maintain phase margin above 43° and prevent peaking or oscillation in filter or cable-driving applications.
What is the typical supply current consumption of the TLV2344IPWR at 3 V?
At VDD = 3 V and TA = 25°C, the TLV2344IPWR draws 1.3 mA typical supply current per amplifier - totaling 5.2 mA for all four channels under no-load conditions. Over the full –40°C to +85°C range, supply current remains within 6.4 mA max, making TLV2344IPWR well-suited for always-on, low-duty-cycle sensor monitoring systems.
Is the TLV2344IPWR pin-compatible with other TSSOP-14 quad op-amps like the LM324 or TLV2444?
No, the TLV2344IPWR is not pin-compatible with standard LM324 or TLV2444 in TSSOP-14. While all use 14-pin TSSOP packages, the pin assignments differ: TLV2344IPWR places VDD+ on pin 4 and GND on pin 8, whereas LM324 (PW package) uses pin 4 for GND and pin 14 for VCC. Always verify pinout using the official TLV2344IPWR schematic diagram before PCB layout.
