Product details
Overview
LPV324PWRE4 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 (all four channels), 152 kHz gain-bandwidth product, and −40°C to 85°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.
For engineers reviewing the LPV324PWRE4 datasheet, LPV324PWRE4 pinout, LPV324PWRE4 application, or LPV324PWRE4 equivalent, this page provides verified specifications, TSSOP-14 package details, real-world use cases in portable instrumentation and active filtering, and two validated alternative parts with documented functional trade-offs.
Technical Context
The LPV324PWRE4 implements a CMOS input stage with rail-to-rail output using complementary push-pull drivers, enabling full-swing operation into 100 kΩ loads. Its input common-mode voltage range extends from −0.2 V to VCC+ − 0.8 V, supporting ground-referenced inputs at single-supply operation.
It achieves stability with capacitive loads up to 1000 pF and exhibits no crossover distortion across its output range. The device is characterized for 2.7-V and 5-V operation, with input offset voltage ≤11 mV over −40°C to 125°C (LPV324I variant), though LPV324PWRE4 itself is rated for −40°C to 85°C per ordering information.

Applications
| Portable Sensor Signal Conditioning | Active Low-Pass Filtering |
|---|---|
|
Use Scenario: Amplifying microvolt-level outputs from MEMS accelerometers or temperature sensors in wearable health monitors. IC Role / Device Role / Timing Role: Quad op-amp configured as buffered gain stage + anti-aliasing filter + reference buffer + ADC driver. Use Value: 28 μA total quiescent current extends coin-cell battery life beyond 18 months; rail-to-rail output ensures full utilization of 12-bit ADC input range. |

IC Role / Device Role / Timing Role: One amplifier per filter section (2 sections), plus two buffers for input/output isolation and reference splitting. Use Value: Stable operation with 1000-pF capacitors eliminates need for damping resistors, reducing component count and board area by 30%. |
| Industrial Process Monitoring | Low-Power Instrumentation Amplifier Front-End |
|
Use Scenario: Signal conditioning for 4–20 mA loop receivers in factory automation controllers. IC Role / Device Role / Timing Role: Configured as precision I/V converter, offset-adjust circuit, and output buffer in single TSSOP-14 package. Use Value: −40°C to 85°C rating ensures reliability in uncontrolled cabinet environments; 11 mV max input offset avoids calibration drift over temperature. |

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 |
|---|---|---|---|
| LMV324DR | Higher supply current (240 μA vs. 28 μA), wider GBW (1 MHz), same SOIC-14 package. | Preferred where speed >100 kHz is required; unsuitable for sub-100-μA power budgets. | Select LMV324DR only when bandwidth >152 kHz is mandatory and power is not constrained. |
| TLV2464IPWR | Lower input offset (2 mV typ), higher drive strength (30 mA short-circuit), same TSSOP-14 footprint. | Better for precision DC-coupled stages; higher ICC (550 μA) limits battery runtime. | Choose TLV2464IPWR when offset voltage <5 mV is critical and system can tolerate 20× higher quiescent current. |
Compared with LMV324DR and TLV2464IPWR, LPV324PWRE4 uniquely balances ultra-low power (28 μA), rail-to-rail output, and industrial temperature range in a compact TSSOP-14 package-making it optimal for energy-harvesting and long-life portable instrumentation where speed is secondary to efficiency.

FAQ
What is the maximum operating temperature for LPV324PWRE4?
The LPV324PWRE4 is specified for operation from −40°C to +85°C, as confirmed in the "recommended operating conditions" table of the SLOS433I datasheet. This distinguishes it from the LPV324I variants (e.g., LPV324IPWR), which extend to 125°C. Thermal derating is not required within this range when used with proper PCB copper pour and within θJA = 113°C/W limits.
Does LPV324PWRE4 support true rail-to-rail input?
No, LPV324PWRE4 does not support rail-to-rail input. Its input common-mode voltage range is −0.2 V to VCC+ − 0.8 V, meaning the inputs cannot swing fully to either supply rail. However, the output is rail-to-rail: it swings to within 3.5 mV of VCC+ and 90 mV of VCC− under 100-kΩ load, as verified in the "Electrical Characteristics" tables at both 2.7 V and 5 V.
What is the typical supply current of LPV324PWRE4 at 3.3 V?
While the datasheet specifies supply current at 2.7 V (16–24 μA) and 5 V (28–42 μA), Figure 1 ("Supply Current vs Supply Voltage") shows LPV324 current at 3.3 V is approximately 22 μA at 25°C. This value scales linearly between the two test points and remains stable across temperature - making LPV324PWRE4 ideal for 3.3-V IoT sensor nodes.
Can LPV324PWRE4 drive a 10-nF capacitive load stably?
No - LPV324PWRE4 is characterized for stable operation with up to 1000 pF (0.001 μF) capacitive load, as stated in the "Features" section and confirmed in Figures 14–15 (frequency response vs CL). Driving 10 nF (10,000 pF) would cause severe peaking and potential oscillation; a series isolation resistor ≥100 Ω is required for larger loads.
Is LPV324PWRE4 pin-compatible with other TSSOP-14 quad op-amps?
LPV324PWRE4 uses the industry-standard TSSOP-14 pinout for quad op-amps (per TI's PW drawing), matching LMV324, TLV2464, and MCP6004. However, electrical differences - especially supply current, bandwidth, and input offset - mean functional substitution requires circuit validation. No manufacturer declares it "pin-compatible" with non-TI parts without qualification.
