Product details
Overview
LPV324IPWRE4 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 −40°C to 125°C operating range. It delivers rail-to-rail output swing (VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ) and supports general-purpose signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the LPV324IPWRE4 datasheet, LPV324IPWRE4 pinout, LPV324IPWRE4 application, or LPV324IPWRE4 equivalent, key selection criteria include ultra-low quiescent current, guaranteed operation across automotive-grade temperature range, rail-to-rail output capability into 100-kΩ loads, and stable performance with up to 1000 pF capacitive load.
Technical Context
The LPV324IPWRE4 implements a CMOS input stage with rail-to-rail output architecture, enabling full-swing signal handling in single-supply systems down to 2.7 V. Its input common-mode voltage range extends from −0.2 V to VCC+ − 0.8 V, supporting ground-referenced inputs without level-shifting circuitry.
It features no crossover distortion, achieves 74° phase margin with 22 pF load at 5 V, and maintains stability under capacitive loading up to 1000 pF-critical for driving ADC input buffers or long traces in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - enables direct integration into 3.3 V and 5 V logic-supplied systems without regulation overhead. |
| Quiescent Current (per amp) | 28 μA typical at 5 V - allows four-channel amplification in always-on sensor nodes with sub-120 μA total ICC. |
| Gain-Bandwidth Product | 237 kHz at 5 V - sufficient for anti-aliasing filters, DC-coupled transducer conditioning, and slow-control-loop feedback. |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ - maximizes dynamic range in single-supply data acquisition stages. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - accepts signals referenced to ground or near-rail voltages without clipping. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-environment IoT edge nodes. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - reduces need for external protection in cost-sensitive PCB layouts. |

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. | Limited to commercial-temperature industrial or consumer applications; no automotive qualification. | Select LPV324DR for cost-sensitive non-automotive designs where larger SOIC footprint is acceptable. |
| MCP6004-E/ST | Microchip part: 1 µA lower ICC (27 µA), 1 MHz GBW, but only rated to 125°C with reduced parameter guarantees. | Higher bandwidth suits faster control loops; lower ICC improves ultra-low-power runtime, but PSRR and CMRR are 5–10 dB lower. | Choose MCP6004-E/ST when higher speed is needed and PSRR >65 dB is not required for noise-sensitive analog paths. |
Compared with LPV324DR, LPV324IPWRE4 adds automotive-grade temperature support and smaller TSSOP footprint; versus MCP6004-E/ST, it trades 848 kHz bandwidth for superior PSRR (65 dB), CMRR (71 dB), and guaranteed 125°C parametric performance-critical for precision sensor front-ends.

FAQ
What is the maximum operating temperature for LPV324IPWRE4?
The LPV324IPWRE4 is characterized and guaranteed to operate from −40°C to +125°C, meeting automotive-grade thermal requirements. This specification is explicitly confirmed in the "recommended operating conditions" table of the SLOS433I datasheet, and the "I" suffix in the part number denotes the extended temperature grade.
Does LPV324IPWRE4 support true rail-to-rail input?
No, LPV324IPWRE4 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 to within 0.8 V of VCC+. However, the output is rail-to-rail, swinging to within 3.5 mV of VCC+ and 90 mV above VCC− at 100-kΩ load.
What is the typical supply current for LPV324IPWRE4 at 3.3 V?
At 3.3 V supply and TA = 25°C, the typical supply current for LPV324IPWRE4 is approximately 22 μA (interpolated from Figure 1 in the datasheet, which shows ~20 μA at 3 V and ~25 μA at 3.6 V). The datasheet specifies 28 μA typical at 5 V and 16–24 μA at 2.7 V, confirming sub-30 μA operation across its full voltage range.
Can LPV324IPWRE4 drive a 1000-pF capacitive load stably?
Yes, LPV324IPWRE4 is explicitly characterized for stability with up to 1000 pF capacitive load, as stated in the "Features" section and verified in Figure 14 and Figure 15 (frequency response vs. CL). No external isolation resistor is required, simplifying design for ADC input buffering or cable-driving applications.
What package type and lead finish does LPV324IPWRE4 use?
LPV324IPWRE4 uses the TSSOP-14 (PW) package with 0.65 mm pitch and green RoHS-compliant finish (Pb-free, no Sb/Br), with CU NIPDAU lead finish and JEDEC MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH).
