Product details
Overview
LMV324AIPWR from Texas Instruments is a quad-channel, low-voltage (2.5 V to 5.5 V), rail-to-rail output operational amplifier optimized for space-constrained, battery-powered systems. It delivers ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, 70 µA per channel quiescent current, and operates across –40°C to 125°C - enabling precision signal conditioning in smoke detectors, wearable devices, and low-side current sensing.
For engineers reviewing the LMV324AIPWR datasheet, LMV324AIPWR pinout, LMV324AIPWR application, or LMV324AIPWR equivalent, key selection criteria include its resistive open-loop output impedance (1.2 kΩ at 1 MHz), 500 pF capacitive-load drive capability, integrated RFI/EMI filtering, and guaranteed no phase reversal under overdrive - all critical for stable operation with ADC drivers and high-impedance sensor interfaces.
Technical Context
The LMV324AIPWR employs a dual-differential-input architecture: a P-channel pair extends common-mode range to within 100 mV of V–, while a parallel N-channel pair eliminates phase reversal - enabling robust single-supply operation without input clamping. Its class-AB output stage achieves rail-to-rail swing (to within 20 mV of rails at 10 kΩ) and supports stable closed-loop gain ≥1.
Designed for low-voltage portability, the device features unity-gain stability, 30 nV/√Hz input voltage noise density at 10 kHz, and overload recovery time of 0.9 µs. Its open-loop output impedance remains resistive up to 1 MHz, simplifying compensation with capacitive loads far exceeding typical op-amp limits.
Key Specifications

| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs - support rail-to-rail common-mode range (V– – 0.1 V to V+ – 1 V) |
| 4 | V+ | Positive supply rail - accepts 2.5 V to 5.5 V; powers all four amplifiers simultaneously |
| 11 | V– | Negative supply or ground - enables true single-supply operation with inputs down to V– |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324IPWR | Higher max input offset voltage (±3 mV vs ±1 mV); same package, pinout, and supply range | Less suitable for precision DC-coupled sensor paths requiring sub-5 mV total error | Select LMV324AIPWR where offset drift and initial accuracy are critical; LMV324IPWR acceptable for AC-coupled or gain ≥100 systems |
| TLV9004IPWR | Lower quiescent current (60 µA/ch), higher GBW (1 MHz same), but reduced EMI rejection and no integrated RFI filter | Not recommended for noisy industrial or RF-dense environments (e.g., smart meters, gateways) | Choose TLV9004IPWR only when ultra-low power dominates over EMI immunity; LMV324AIPWR preferred for robustness in mixed-signal systems |
Compared with LMV324IPWR, LMV324AIPWR offers tighter offset and drift for precision analog front-ends; versus TLV9004IPWR, it trades 10 µA/ch higher IQ for superior EMI resilience and guaranteed no-phase-reversal - making it the default choice for safety-critical or electrically noisy applications.

FAQ
What is the maximum capacitive load the LMV324AIPWR can drive without oscillation?
The LMV324AIPWR is characterized to drive up to 500 pF capacitive load stably in unity-gain configuration due to its resistive open-loop output impedance. At 1000 pF, phase margin drops below 45°, risking instability; for loads >500 pF, TI recommends adding a small series resistor (10–50 Ω) between output and capacitance. This behavior is confirmed in Figure 5-21 of the LMV324AIPWR datasheet.
Does the LMV324AIPWR support true rail-to-rail input?
No - the LMV324AIPWR provides rail-to-rail *output* swing but only rail-to-rail *input common-mode range down to V–*, extending 100 mV beyond V– and stopping 1 V below V+. Input voltages must remain within (V– – 0.1 V) to (V+ – 1 V) to meet specifications. Exceeding this range may cause phase reversal or degraded CMRR, as detailed in Section 5.7 of the LMV324AIPWR datasheet.
Can the LMV324AIPWR operate from a single 2.5 V supply?
Yes - the LMV324AIPWR is fully specified from 2.5 V to 5.5 V single supply (or ±1.25 V to ±2.75 V dual supply). At 2.5 V, it maintains 70 µA/channel quiescent current, ±4 mV max input offset, and rail-to-rail output swing to within 50 mV of rails at 2 kΩ load. All electrical characteristics in Table 5.7 are validated across this full voltage range.
What is the overload recovery time of the LMV324AIPWR?
The LMV324AIPWR recovers from output saturation in 0.9 µs (typical), measured under VS = 5 V, G = –10, VIN = 600 mVpp. This fast recovery enables accurate pulse-amplitude measurement in transient-rich environments like motor current sensing or burst-mode sensor readouts. The value is documented in Section 5.7 (tOR parameter) and verified in Figure 5-23 of the LMV324AIPWR datasheet.
Is the LMV324AIPWR pin-compatible with older LMV324 variants?
Yes - the LMV324AIPWR shares identical 14-pin TSSOP (PW) package, pinout, and footprint with LMV324IPWR and LMV324IDR. All share the same V+, V–, IN+/–, and OUT assignments per channel (Table 4-3). However, the 'A' suffix denotes improved offset voltage (±1 mV vs ±3 mV) and enhanced EMI rejection; no PCB changes are required for drop-in replacement in existing designs.
