Product details
Overview
TLV2324IPW from Texas Instruments is a quad low-voltage, low-power operational amplifier optimized for single-supply operation in battery-powered sensor interfaces and industrial transmitters. It delivers 27 µA max supply current per channel at –40°C to +85°C, supports 2.7V to 8V supply range, features rail-to-rail output swing down to the negative rail, and maintains input common-mode range extending to VDD – 1V at 25°C - enabling direct interfacing with high-impedance sensors in smoke detectors and pressure transmitters.
For engineers reviewing the TLV2324IPW datasheet, TLV2324IPW pinout, TLV2324IPW application, or TLV2324IPW equivalent, key selection criteria include ultra-low quiescent current (≤108 µA total), input offset voltage ≤12 mV over temperature, TSSOP-14 package compatibility, and verified performance at 3V/5V for portable analog front-ends.
Technical Context
The TLV2324IPW uses Texas Instruments' LinCMOS™ silicon-gate process to achieve 10¹² Ω typical input impedance and sub-picoampere input bias current (0.6 pA typ at 25°C), making it suitable for high-impedance sensor buffering. Its input stage supports common-mode voltages from –0.2 V to VDD – 1.2 V across temperature, while the output stage drives loads down to the negative rail with 190 mV low-level output voltage at 1 mA sink current.
Designed explicitly for single-supply systems, the device avoids internal level-shifting circuitry - instead relying on CMOS input transistors and Class AB output stages to maintain stability and precision at 3V operation. Unity-gain bandwidth is 27 kHz at 3V (25°C) and 85 kHz at 5V (25°C), with phase margin ≥28° over full temperature and supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct use with 3.3 V and 5 V logic rails and extended battery life in 2-cell alkaline or Li-ion systems. |
| Quiescent Current (per channel) | 26 µA typ / 108 µA max at –40°C to +85°C - ensures multi-year operation in always-on sensor nodes. |
| Input Offset Voltage | 1.1 mV min / 12 mV max over temperature - supports precision DC-coupled signal conditioning without trimming. |
| Input Bias Current | 0.6 pA typ at 25°C - minimizes voltage error when amplifying signals from >1 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors). |
| Common-Mode Input Range | –0.2 V to VDD – 1.2 V - allows ground-referenced inputs and rail-sensing in single-supply configurations. |
| Output Voltage Swing | Within 190 mV of negative rail at 1 mA - supports true single-supply operation with zero-output capability for active-low comparators or level-shifting. |
| Unity-Gain Bandwidth | 27 kHz at 3 V / 85 kHz at 5 V (25°C) - sufficient for slow-varying industrial sensor outputs (e.g., 4–20 mA loop receivers, thermistor bridges). |

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 |
|---|---|---|---|
| TLV2374IPW | Higher supply current (125 µA max), wider GBW (1 MHz), but higher VIO (3 mV typ) and no 3V characterization guarantee. | Better for higher-speed sensor interfaces (>100 kHz), less suitable for ultra-low-power battery nodes requiring <100 µA total. | Select TLV2374IPW only if bandwidth >100 kHz is required and supply current budget allows ≥2× increase. |
| LP324DR | Higher quiescent current (120 µA max), lower input impedance (10⁹ Ω), no guaranteed 3V operation or rail-to-rail output. | Suitable for cost-sensitive non-battery applications where 5V supply is fixed and precision is secondary. | Choose LP324DR only for legacy 5V industrial designs where layout space and power efficiency are not constrained. |
Compared with TLV2324IPW, TLV2374IPW trades ultra-low power for speed and LP324DR sacrifices precision and rail-to-rail capability for cost - making TLV2324IPW the optimal choice for new battery-powered sensor nodes demanding sub-100 µA total supply current and verified 3V operation.

FAQ
What is the maximum supply voltage rating for TLV2324IPW?
The absolute maximum supply voltage for TLV2324IPW is 8 V, as specified in Section 5.1 of the datasheet. Operation above this voltage risks permanent damage. The recommended operating range is 2.7 V to 8 V, with full characterization at 3 V and 5 V. Exceeding 8 V violates absolute maximum ratings and voids reliability guarantees - TLV2324IPW must never be operated beyond this limit in any design.
Does TLV2324IPW support true rail-to-rail input operation?
TLV2324IPW supports rail-to-rail *output* swing down to the negative rail, but its input common-mode range extends only to VDD – 1.2 V at temperatures other than 25°C (and VDD – 1 V at 25°C). It does not support full rail-to-rail input - the upper limit is 1.2 V below VDD. This is confirmed in Table 5.3 (Recommended Operating Conditions) and Figure 5-10. TLV2324IPW is therefore unsuitable for applications requiring input signals equal to VDD.
What is the input bias current specification for TLV2324IPW at 85°C?
At 85°C, TLV2324IPW has a maximum input bias current of 2000 pA (2 nA), as stated in Table 5.7 under "IIB" at full temperature range. The typical value is 200 pA. This parameter is critical for high-impedance sensor interfaces - TLV2324IPW's 0.6 pA typical at 25°C degrades predictably with temperature, and system designs must account for the 2 nA worst-case at end-of-life hot conditions.
Can TLV2324IPW drive a 10 kΩ load while maintaining rail-to-rail output?
Yes - TLV2324IPW is fully specified to drive loads ≥10 kΩ with rail-to-rail output swing. Its output stage is characterized for ±30 mA short-circuit current and 190 mV low-level output voltage at 1 mA sink (Table 5.7), meaning a 10 kΩ load draws only 330 µA at 3.3 V - well within capability. No external boost circuitry is needed for standard sensor interface loads, and TLV2324IPW maintains accuracy under these conditions per Section 5.7 test conditions.
Is TLV2324IPW qualified for automotive applications?
No - TLV2324IPW is not AEC-Q200 qualified and is rated only for industrial temperature range (–40°C to +85°C), not automotive (–40°C to +125°C). Its datasheet contains no automotive stress test data, qualification reports, or PPAP documentation. For automotive use, TI recommends alternatives such as TLV9064-Q1. TLV2324IPW remains appropriate for industrial, medical, and consumer safety devices like smoke detectors, but not for under-hood or ADAS applications.
