Product details
Overview
LPV324IPWE4 from Texas Instruments is a quad, rail-to-rail output, low-voltage (2.7 V to 5 V), low-power (28 μA typical at 5 V) operational amplifier optimized for portable and space-constrained applications. It delivers 152 kHz gain-bandwidth product, ±100 mV output swing near rails at 100 kΩ load, and operates across −40°C to +125°C.
For engineers reviewing the LPV324IPWE4 datasheet, LPV324IPWE4 pinout, LPV324IPWE4 application, or LPV324IPWE4 equivalent, key selection criteria include its ultra-low supply current, rail-to-rail output capability with ground-sensing input, stable operation into 1000 pF capacitive loads, and qualification for extended-temperature industrial use.
Technical Context
The LPV324IPWE4 implements a CMOS input stage with rail-to-rail output stage, enabling full dynamic range utilization in single-supply systems. Its input common-mode voltage range extends from −0.2 V to VCC+ − 0.8 V, supporting ground-referenced sensing.
It achieves stability without external compensation across 1000 pF capacitive loads and exhibits no crossover distortion. The device is characterized for operation up to 125°C, with input offset voltage ≤11 mV and supply current ≤125 μA over temperature.

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 |
|---|---|---|---|
| LPV324DR | SOIC-14 package, same electrical specs, rated −40°C to +85°C only | Not suitable for extended-temperature environments like under-hood automotive or industrial enclosures | Select LPV324DR only when cost is primary and operating temperature stays below 85°C. |
| MCP6004-E/ST | Microchip part; 1 μA lower supply current but 100 kHz GBW, 1.8 V min supply, no 125°C rating | Compatible for ultra-low-power portable devices but lacks high-temp reliability and bandwidth margin | Choose MCP6004-E/ST for sub-2 V systems or where 152 kHz GBW is unnecessary. |

FAQ
What is the maximum operating temperature of the LPV324IPWE4?
The LPV324IPWE4 is specified for continuous operation from −40°C to +125°C. This extended temperature range is confirmed in the "recommended operating conditions" table of the SLOS433I datasheet and applies to all electrical parameters unless otherwise noted. The 'I' suffix in LPV324IPWE4 explicitly denotes the 125°C grade, distinguishing it from the standard −40°C to +85°C LPV324 variants.
Does the LPV324IPWE4 support rail-to-rail input?
No, the LPV324IPWE4 does not support rail-to-rail input. Its input common-mode voltage range is specified as −0.2 V to VCC+ − 0.8 V, meaning the inputs can go 0.2 V below ground but only up to 0.8 V below the positive rail. However, the input stage does include ground-sensing capability, allowing signals referenced to system ground to be amplified directly in single-supply configurations.
What is the typical supply current for the LPV324IPWE4 at 3.3 V?
While the datasheet specifies 28 μA typical supply current at 5 V (for all four channels), measurements and Figure 1 (Supply Current vs Supply Voltage) confirm that at 3.3 V and 25°C, the LPV324IPWE4 draws approximately 18 μA typical. This reduction scales nearly linearly with supply voltage and remains well within the 24 μA maximum limit stated for the −40°C to +85°C range at 3.3 V.
Can the LPV324IPWE4 drive a 10 nF capacitive load without oscillation?
No-the LPV324IPWE4 is characterized for stability with up to 1000 pF (1 nF) capacitive load, as explicitly stated in the "Features" section and verified in Figures 14–15 (frequency response vs CL). Driving 10 nF exceeds this limit and risks phase margin degradation and potential oscillation. For larger capacitive loads, an external series resistor (e.g., 10–50 Ω) between the output and load is required to restore stability.
Is the LPV324IPWE4 pin-compatible with the standard LPV324DR in SOIC-14?
Yes, the LPV324IPWE4 in TSSOP-14 (PW) and the LPV324DR in SOIC-14 (D) share identical pin numbering and function mapping per the "LPV324 . . . D OR PW PACKAGE (TOP VIEW)" diagram in the datasheet. Both have 14 pins with matching assignments (1OUT, 1IN−, 1IN+, VCC+, etc.). However, due to differing package footprints and thermal characteristics, PCB layout changes are required for physical replacement.
