Product details
Overview
LPV324PWE4 from Texas Instruments is a quad, rail-to-rail output, low-voltage (2.7 V to 5 V), low-power operational amplifier with 28 μA typical supply current per device at 5 V, 152 kHz gain-bandwidth product, and input common-mode range extending to −0.2 V below VCC−. It operates across −40°C to 125°C and is used in battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the LPV324PWE4 datasheet, LPV324PWE4 pinout, LPV324PWE4 application, or LPV324PWE4 equivalent, this page delivers verified electrical specs, TSSOP-14 package details, rail-to-rail output behavior at 100-kΩ load, ESD robustness (2-kV HBM), and direct alternatives for low-voltage analog front-end design.
Technical Context
The LPV324PWE4 implements a CMOS input stage with rail-to-rail output swing (VCC+ − 3.5 mV / VCC− + 90 mV at 100-kΩ), stable operation with up to 1000 pF capacitive load, and no crossover distortion. Its input common-mode voltage range spans −0.2 V to VCC+ − 0.8 V, enabling ground-sensing capability in single-supply systems.
It achieves a 152 kHz gain-bandwidth product with only 28 μA supply current at 5 V, delivering a high speed-power ratio optimized for space-constrained, energy-sensitive applications. The device is characterized over −40°C to 125°C and meets JESD 78 Class II latch-up performance (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports single-cell Li-ion and dual-cell alkaline battery systems without regulation. |
| Supply Current (typ) | 28 μA - enables multi-year operation in always-on sensor nodes powered by coin cells. |
| Gain-Bandwidth Product | 152 kHz - sufficient for anti-aliasing filters, DC-coupled transducer amplification, and slow-control loops. |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV @ 100-kΩ - maximizes dynamic range in 3.3-V or 5-V ADC interfaces. |
| Input Offset Voltage (max) | 11 mV over −40°C to 125°C - suitable for precision but non-critical offset applications like temperature monitoring. |
| ESD Protection (HBM) | 2000 V - reduces need for external protection in handheld and industrial I/O modules. |

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 |
|---|---|---|---|
| TLV2464IPW | Higher supply current (550 μA/channel), 6.4 MHz GBW, rail-to-rail input/output, 1.8–6 V operation. | Better for higher-speed signal chains (e.g., audio preamps), less suitable for ultra-low-power battery systems. | Select TLV2464IPW when bandwidth >1 MHz is required and power budget allows ≥2.2 mA total supply current. |
| MCP6004-E/ST | Lower supply current (1 μA/channel), 1 MHz GBW, rail-to-rail input/output, 1.8–6 V operation, wider temp range (−40°C to 125°C). | Superior for nano-power applications (e.g., wireless sensor nodes), but lower GBW limits closed-loop stability at high gains. | Choose MCP6004-E/ST when sub-5-μA total current is mandatory and bandwidth ≤100 kHz suffices. |
Compared with LPV324PWE4, TLV2464IPW trades 20× higher power for 42× more bandwidth, while MCP6004-E/ST cuts power by 96% but reduces GBW by 33% - making LPV324PWE4 the optimal balance for mid-speed, low-power industrial and portable analog signal chains.

FAQ
What is the maximum operating temperature for LPV324PWE4?
The LPV324PWE4 is specified for continuous operation from −40°C to 125°C, matching the extended temperature grade (LPV324I) defined in the SLOS433I datasheet. This rating applies to the TSSOP-14 (PW) package variant and is validated per JEDEC JESD22-A108.
Does LPV324PWE4 support rail-to-rail input?
No, LPV324PWE4 does not support rail-to-rail input. Its input common-mode voltage range is −0.2 V to VCC+ − 0.8 V, meaning it accepts signals down to 0.2 V below ground but cannot swing fully to VCC+. However, it does provide true rail-to-rail output swing at 100-kΩ load.
What is the typical supply current for LPV324PWE4 at 3.3 V?
At 3.3 V supply and 25°C, the typical supply current for LPV324PWE4 is 24 μA - interpolated from the 2.7-V (24 μA typ) and 5-V (28 μA typ) data points in the datasheet's electrical characteristics tables. This value reflects total current for all four amplifiers.
Can LPV324PWE4 drive a 1000-pF capacitive load stably?
Yes, LPV324PWE4 is explicitly characterized for stable operation with up to 1000-pF capacitive load, as confirmed in the "Stable With Capacitive Load of 1000 pF" feature list and Figure 14–15 frequency response plots in the SLOS433I datasheet.
Is LPV324PWE4 RoHS compliant and lead-free?
Yes, LPV324PWE4 is RoHS compliant and lead-free, meeting the "Green (RoHS & no Sb/Br)" eco-plan classification per TI's packaging addendum. It uses Cu-Ni-Pd-Au (Cu NIPDAU) lead finish and is rated MSL Level-1 (260°C peak reflow).
