Product details
Overview
TLV2324IPWLE from Texas Instruments is a quad, low-voltage, rail-to-rail output operational amplifier optimized for single-supply operation at 2.7V–8V. It delivers 27µA max supply current per channel, 10mV max input offset voltage at 25°C, and rail-to-rail output swing down to the negative rail - enabling precision signal conditioning in battery-powered sensor front-ends such as pressure transmitters and smoke detectors.
For engineers reviewing the TLV2324IPWLE datasheet, TLV2324IPWLE pinout, TLV2324IPWLE application, or TLV2324IPWLE equivalent, key selection criteria include ultra-low quiescent current (≤27µA/channel), input common-mode range extending to VDD – 1V, LinCMOS™ input impedance (>10¹²Ω), and TSSOP-14 package compatibility with space-constrained portable designs.
Technical Context
The TLV2324IPWLE uses Texas Instruments' LinCMOS™ silicon-gate process to achieve ultra-low input bias current (0.6pA typ at 25°C) and high input impedance (10¹²Ω typ), making it suitable for interfacing with high-impedance sensors and passive filter networks. Its input stage supports common-mode voltages from –0.2V to VDD – 1V (at 25°C), and its output drives to within 115mV of the negative rail at 1mA load.
Each of the four independent amplifiers operates over –40°C to +85°C with fully characterized performance at 3V and 5V supplies. The device incorporates ESD protection rated to 2000V (MIL-STD-883C, Method 3015.2) and is latch-up immune, supporting robust operation in industrial field transmitter environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 8V - enables direct interface with 3.3V and 5V logic rails and battery systems down to two alkaline cells. |
| Quiescent Current per Channel | 26µA typ / 108µA max (–40°C to +85°C) - allows multi-channel sensing with sub-500µA total system bias current. |
| Input Offset Voltage | 1.1mV min / 10mV max at 25°C - supports DC-coupled sensor amplification without frequent calibration. |
| Input Bias Current | 0.6pA typ at 25°C - preserves signal integrity when amplifying from piezoresistive or capacitive sensors. |
| Common-Mode Input Range | –0.2V to VDD – 1V at 25°C - permits ground-referenced inputs and single-supply level-shifting without external biasing. |
| Output Voltage Swing | Within 115mV of negative rail at 1mA - ensures full dynamic range utilization in low-voltage, rail-to-rail output stages. |
| Unity-Gain Bandwidth | 27kHz typ at 3V / 85kHz typ at 5V - sufficient for slow-sensing applications including temperature, pressure, and gas detection. |

Applications
| Smoke and Heat Detector | Pressure Transmitter |
|---|---|
|
Use Scenario: Amplifies low-level analog output from ionization or photoelectric smoke chamber and thermistor-based ambient temperature sensor. IC Role / Device Role / Timing Role: Quad op-amp provides simultaneous signal conditioning for smoke detection, temperature compensation, alarm driver, and self-test circuitry. Use Value: 27µA/channel quiescent current enables >5-year battery life in standby mode while maintaining fast wake-up response. |
Use Scenario: Conditions millivolt-level bridge output from piezoresistive pressure sensor in HVAC or industrial process control. IC Role / Device Role / Timing Role: One channel performs zero-offset correction, one handles gain scaling, one buffers reference, and one drives 4–20mA loop transmitter. Use Value: 10¹²Ω input impedance prevents bridge imbalance error; rail-to-rail output supports full-scale 0–5V DAC interface. |
| Temperature Transmitter | Motion Detector |
|
Use Scenario: Interfaces with RTD or thermocouple via cold-junction compensation and linearization circuitry in wired industrial sensors. IC Role / Device Role / Timing Role: Configured as instrumentation amplifier front-end, reference buffer, filter stage, and output driver for HART modulation. Use Value: 10mV max input offset voltage limits temperature measurement error to <±0.1°C over full range with 100Ω Pt RTD. |
Use Scenario: Amplifies microvolt-level pyroelectric sensor output in PIR-based occupancy and security systems. IC Role / Device Role / Timing Role: First stage low-noise preamp (68nV/√Hz), second stage active bandpass filter, third stage comparator reference, fourth stage LED/alarm driver. Use Value: Sub-picoampere input bias current avoids signal loss across high-value feedback resistors used in ultra-high-gain AC-coupled stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550µA/channel), higher GBW (6.4MHz), rail-to-rail I/O - not drop-in; requires layout and power budget revision. | Better suited for higher-speed sensor interfaces (e.g., ultrasonic flow meters); unsuitable for multi-year battery life targets. | Select TLV2464IDR only when bandwidth >100kHz and drive capability >25mA are required - not for ultra-low-power legacy replacement. |
| LP324DR | Lower cost, bipolar input (30nA IB), wider VDD range (3–32V), but no rail-to-rail output and 100µA/channel IQ - lacks LinCMOS™ input performance. | Applicable in line-powered industrial controllers where input impedance and battery life are secondary concerns. | Choose LP324DR for cost-sensitive, non-battery applications requiring wide supply range and moderate precision - not for high-Z sensor front-ends. |
Compared with TLV2464IDR and LP324DR, the TLV2324IPWLE uniquely balances ultra-low IQ (≤27µA/channel), LinCMOS™ input impedance (>10¹²Ω), and rail-to-rail output in a TSSOP-14 package - making it irreplaceable for long-life, high-impedance, single-supply sensor signal chains.

FAQ
What is the maximum operating temperature range for the TLV2324IPWLE?
The TLV2324IPWLE is fully specified and tested over an operating free-air temperature range of –40°C to +85°C. All key parameters-including supply current (108µA max), input offset voltage (12mV max), and common-mode input range-are guaranteed across this full industrial temperature range, ensuring reliable operation in outdoor and factory-floor environments.
Does the TLV2324IPWLE support true rail-to-rail input operation?
The TLV2324IPWLE does not support rail-to-rail input; its common-mode input voltage range extends to the negative rail (GND) and up to VDD – 1V at 25°C (VDD – 1.2V over full temperature range). This allows ground-referenced inputs but requires external biasing for signals near VDD - unlike rail-to-rail input op-amps such as the TLV9064.
Can the TLV2324IPWLE drive a 4–20mA current loop directly?
No, the TLV2324IPWLE cannot drive a 4–20mA loop directly. Its output current capability is ±30mA peak, but it lacks the internal current-sense and feedback architecture required for compliant 4–20mA transmission. It is commonly used as the front-end amplifier and reference buffer in conjunction with a dedicated 4–20mA IC like the XTR116 or XTR117.
What is the typical input noise voltage of the TLV2324IPWLE at 1kHz?
The TLV2324IPWLE has a typical equivalent input noise voltage of 68nV/√Hz at 1kHz, as measured with RS = 20Ω and specified in Section 5.8 of the datasheet. This low noise performance-combined with ultra-low input bias current-makes it well-suited for amplifying weak signals from high-impedance sensors without significant degradation.
Is the TLV2324IPWLE pin-compatible with other TSSOP-14 quad op-amps?
The TLV2324IPWLE follows standard TSSOP-14 pinout conventions for quad op-amps (e.g., inputs on pins 2/3, 5/6, 9/10, 12/13; outputs on 1, 7, 8, 14; supplies on 4 and 11), but it is not functionally or electrically pin-compatible with most alternatives due to differences in input stage architecture, supply current, and output drive. Always verify pin functions using Table 4-2 before substitution.
