Product details
Overview
TLV2324IPWR from Texas Instruments is a quad, low-voltage, rail-to-rail output operational amplifier optimized for single-supply battery-powered systems. It operates from 2.7V to 8V, draws only 68 μA per channel at 5V (108 μA over –40°C to +85°C), features 10 mV max input offset voltage at 25°C, and supports common-mode input down to the negative rail and up to VDD – 1V - enabling direct sensor interfacing in smoke detectors and industrial transmitters.
For engineers reviewing the TLV2324IPWR datasheet, TLV2324IPWR pinout, TLV2324IPWR application, or TLV2324IPWR equivalent, this page delivers verified electrical specs, TSSOP-14 package details, real-world use cases in field transmitters and motion detection, and two validated alternative op-amps with documented functional and parametric differences.
Technical Context
The TLV2324IPWR uses Texas Instruments' LinCMOS™ silicon-gate process to achieve ultra-low supply current (≤108 μA full-range) while maintaining high input impedance (10¹² Ω typical) and sub-picoampere bias currents. Its input stage supports rail-to-rail common-mode range (–0.2 V to VDD – 1.2V), and its output swings to the negative rail with 190 mV low-level output voltage at 1 mA load.
This device is fully characterized at both 3V and 5V, with unity-gain bandwidth of 27 kHz (3V) / 85 kHz (5V), slew rate of 0.02 V/µs (3V) / 0.03 V/µs (5V), and CMRR ≥59 dB across temperature - making it suitable for precision, low-power signal conditioning where supply headroom and quiescent current are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 8V - enables direct operation from single Li-ion, 3.3V, or 5V rails without regulation. |
| Quiescent Current per Channel | 68 μA typ @ 5V, 108 μA max over –40°C to +85°C - supports multi-year battery life in portable sensors. |
| Input Offset Voltage | 10 mV max @ 25°C - sufficient for medium-accuracy DC-coupled amplification in transmitter front-ends. |
| Common-Mode Input Range | Extends to negative rail and up to VDD – 1.2V - allows ground-referenced sensor inputs and high-side sensing. |
| Output Voltage Swing | Reaches negative rail; VOL = 190 mV max @ 1 mA - supports low-voltage logic interfacing and analog-to-digital conversion near ground. |
| Unity-Gain Bandwidth | 27 kHz @ 3V / 85 kHz @ 5V - adequate for slow-varying industrial signals (e.g., pressure, temperature, level). |
| Input Bias Current | 0.6 pA typ @ 25°C - preserves signal integrity when amplifying high-impedance sources like piezoresistive or thermistor bridges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IPWR | Higher supply current (550 μA/ch), higher GBW (6.4 MHz), rail-to-rail I/O, lower VIO (2 mV max) | Better for higher-speed or higher-precision sensor interfaces where power budget allows >5× current draw | Select TLV2464IPWR when accuracy and bandwidth outweigh battery life constraints; not drop-in due to higher IDD and different pin-compatible layout requirements. |
| LPV521MG/NOPB | Lower supply current (320 nA), lower bandwidth (15.5 kHz), single-channel, smaller SC70-5 package | Targeted for ultra-long-life, single-channel, space-constrained applications (e.g., wearable health sensors) | Choose LPV521MG/NOPB only for single-channel use cases requiring nanoamp quiescent current; requires redesign for quad functionality and TSSOP-14 footprint. |
Compared with TLV2324IPWR, TLV2464IPWR trades 5× higher supply current for 200× greater bandwidth and improved DC precision, while LPV521MG/NOPB reduces current by 300× but sacrifices channel count, package compatibility, and output drive capability - making TLV2324IPWR the optimal balance for quad, battery-powered industrial transmitters.

FAQ
What is the maximum operating temperature range for TLV2324IPWR?
The TLV2324IPWR is rated for continuous operation from –40°C to +85°C ambient temperature. All key parameters-including supply current (108 μA max), input offset voltage (12 mV max), and common-mode input range-are specified across this full industrial temperature range, ensuring reliable performance in harsh field environments.
Does TLV2324IPWR support true rail-to-rail input operation?
Yes, TLV2324IPWR supports rail-to-rail input: its common-mode input voltage range extends to the negative rail (GND) and up to VDD – 1.2V across temperature. At 25°C, it reaches VDD – 1V. This allows direct interfacing with ground-referenced sensors and eliminates the need for external bias networks in many single-supply configurations.
What is the output voltage swing capability of TLV2324IPWR?
The TLV2324IPWR output swings to the negative rail (GND) and delivers VOH ≥1.7 V at 1 mA load with 3V supply. At 5V supply, VOH ≥3 V under same conditions. Low-level output voltage is specified as VOL ≤190 mV max at 1 mA, confirming true rail-to-rail output behavior essential for interfacing with low-voltage ADCs and logic.
Can TLV2324IPWR be used with a 3.3V supply?
Yes, TLV2324IPWR is fully characterized and specified at 3V supply. It operates reliably from 2.7V to 8V, with key metrics including 68 μA typical supply current, 27 kHz unity-gain bandwidth, and 0.02 V/µs slew rate - making it ideal for 3.3V battery-powered systems such as wireless sensor nodes and portable instrumentation.
Is TLV2324IPWR pin-compatible with other quad op-amps in TSSOP-14?
No, TLV2324IPWR has a unique pinout optimized for its LinCMOS architecture and single-supply operation. While it shares the TSSOP-14 package outline with devices like LM324 or TLV2464, its pin assignments (e.g., VDD+ on Pin 4, GND on Pin 11) differ significantly - requiring PCB layout revision for substitution. Always verify pin functions using Table 4-2 in the official datasheet.
