Product details
Overview
LPV324IDRE4 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 ground - used in battery-powered sensor signal conditioning and portable medical front-ends.
For engineers reviewing the LPV324IDRE4 datasheet, LPV324IDRE4 pinout, LPV324IDRE4 application, or LPV324IDRE4 equivalent, key selection criteria include its guaranteed operation from −40°C to +125°C, rail-to-rail output swing within 3.5 mV of VCC+ and 90 mV of VCC− at 100-kΩ load, stable performance with 1000-pF capacitive loads, and SOIC-14 package compatibility with legacy LMV324 layouts.
Technical Context
The LPV324IDRE4 implements a CMOS input stage with complementary differential pairs enabling rail-to-rail input common-mode voltage range (−0.2 V to VCC+ − 0.8 V) and low input bias current (2 nA typical at 25°C). Its output stage uses push-pull architecture to achieve rail-to-rail swing while maintaining stability with ≥1000-pF capacitive loads without external compensation.
It operates across 2.7 V–5 V supply rails and delivers 152 kHz GBW with only 28 μA total supply current for all four amplifiers - achieving a speed-power ratio optimized for always-on, low-duty-cycle sensing nodes where quiescent current directly impacts battery life.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports single-cell Li-ion, two-cell alkaline, and 3.3-V system rails without level-shifting. |
| Quiescent Current (All Channels) | 28 μA typical at 5 V - enables multi-year operation in coin-cell-powered IoT endpoints. |
| Gain-Bandwidth Product | 152 kHz - sufficient for DC–10 kHz sensor amplification (e.g., thermistor, strain gauge, ECG leads). |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100-kΩ load - maximizes dynamic range in low-voltage ADC interfaces. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - allows direct connection to grounded sensors and single-supply transducer outputs. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial motor control, and harsh-environment monitoring. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - reduces need for external protection in space-constrained PCBs. |
Pinout & Package
LPV324IDRE4 is housed in a 14-pin SOIC (D) package with standard 1.27-mm pitch, 8.65-mm body width, and RoHS-compliant CU NIPDAU lead finish (MSL Level-1, 260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives low-impedance loads up to 100 kΩ while maintaining rail-to-rail swing. |
| 2 | 1IN− | Inverting input of Amplifier A - accepts signals down to −0.2 V for true single-supply operation. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - high-impedance node (2 nA bias) minimizes loading on resistive sensors. |
| 4 | VCC− | Negative supply rail (typically GND) - shared reference for all four amplifiers in the quad package. |
| 5 | 2IN+ | Non-inverting input of Amplifier B - electrically isolated from other channels; supports independent feedback networks. |
| 6 | 2IN− | Inverting input of Amplifier B - matched offset and bias specs ensure channel-to-channel tracking in multi-stage filters. |
| 7 | 2OUT | Amplifier B output - identical AC/DC specs to Pin 1; enables dual-path signal processing in one footprint. |
| 8 | VCC+ | Positive supply rail (2.7–5 V) - powers all four op-amps; low current draw eases LDO sizing. |
| 9 | 3OUT | Amplifier C output - fully specified for −40°C to +125°C; usable in temperature-compensated analog front-ends. |
| 10 | 3IN− | Inverting input of Amplifier C - supports unity-gain stable configurations with >1000-pF capacitive loads. |
| 11 | 3IN+ | Non-inverting input of Amplifier C - same input voltage range and noise specs as Pins 2/3/5/6/10/12. |
| 12 | 4IN− | Inverting input of Amplifier D - enables fourth independent gain stage without adding discrete ICs. |
| 13 | 4IN+ | Non-inverting input of Amplifier D - allows simultaneous conditioning of four sensor channels (e.g., 4-wire RTD, quad thermocouple). |
| 14 | 4OUT | Amplifier D output - completes quad functionality; all outputs drive 100-kΩ loads with <10-mV headroom to rails. |

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 |
|---|---|---|---|
| LMV324IDR | Higher 120-μA supply current per device; same SOIC-14 package and pinout; 1-MHz GBW but higher power. | Better suited for higher-speed signal paths (>100 kHz) where power budget allows. | Select LMV324IDR only if bandwidth >152 kHz is required and 4× higher supply current is acceptable. |
| TLV2464CDR | Lower 23-μA supply current; 6.4-V max supply; rail-to-rail input/output; 6.4-MHz GBW; same SOIC-14 pinout. | Supports wider supply range and higher bandwidth but requires design validation for 125°C operation. | Choose TLV2464CDR for extended voltage range or higher speed, but verify thermal performance at 125°C. |
Compared with LMV324IDR and TLV2464CDR, LPV324IDRE4 provides the lowest power consumption among SOIC-14 quad op-amps rated for 125°C operation - making it optimal for thermally constrained, long-life embedded systems where bandwidth requirements stay below 200 kHz.

FAQ
What is the maximum operating temperature specification for LPV324IDRE4?
The LPV324IDRE4 is characterized and guaranteed to operate from −40°C to +125°C - confirmed in the official Texas Instruments SLOS433I datasheet revision March 2005. This extended temperature grade makes LPV324IDRE4 suitable for under-dash automotive modules, industrial motor drives, and outdoor environmental monitoring equipment where ambient temperatures exceed 85°C.
Does LPV324IDRE4 support rail-to-rail input operation?
LPV324IDRE4 supports rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range is specified as −0.2 V to VCC+ − 0.8 V, meaning it accepts signals down to 0.2 V below ground and up to 0.8 V below the positive rail. This allows true single-supply operation with grounded sensors, but does not accommodate input voltages at the exact VCC+ rail.
Can LPV324IDRE4 drive a 1000-pF capacitive load without oscillation?
Yes - LPV324IDRE4 is explicitly characterized for stability with capacitive loads up to 1000 pF, as stated in the "Features" section of the SLOS433I datasheet. This eliminates the need for series isolation resistors when driving LCD bias networks, piezoelectric transducers, or long PCB traces, simplifying layout and reducing component count in space-constrained designs.
What is the typical supply current for LPV324IDRE4 at 2.7 V and 25°C?
At 2.7 V and 25°C, the typical supply current for LPV324IDRE4 is 16 μA (per device data sheet Table 5, "2.7-V electrical characteristics"). This value reflects the total current drawn by all four amplifiers combined - confirming its suitability for ultra-low-power applications such as energy-harvesting sensor nodes and coin-cell-powered wearables.
Is LPV324IDRE4 pin-compatible with standard LMV324 variants?
Yes - LPV324IDRE4 uses the same SOIC-14 (D) package and identical pinout as LMV324D, LMV324DR, and LMV324IDR. Engineers can perform drop-in replacements in existing designs, though they must verify that the lower bandwidth (152 kHz vs. 1 MHz) and reduced output drive capability meet system requirements.
