Product details
Overview
LPV324M/NOPB from Texas Instruments is a quad, rail-to-rail output, micropower operational amplifier optimized for low-voltage (2.7 V to 5 V), battery-powered applications. It delivers 152 kHz gain-bandwidth product, 28 µA total supply current (all four channels), −40°C to +85°C industrial temperature range, and rail-to-rail output swing (V+ −3.5 mV / V− +90 mV at 100 kΩ load), enabling precision signal conditioning in portable medical sensors and handheld instrumentation.
For engineers reviewing the LPV324M/NOPB datasheet, LPV324M/NOPB pinout, LPV324M/NOPB application, or LPV324M/NOPB equivalent, key selection considerations include its 28 µA quiescent current per device (not per channel), SOIC-14 or TSSOP-14 package options, input common-mode range extending to −0.2 V, and bipolar input stage supporting low-noise, ground-sensing operation in single-supply systems.
Technical Context
The LPV324M/NOPB implements a bipolar-input, rail-to-rail output architecture with no crossover distortion, enabling clean signal amplification near supply rails. Its 152 kHz GBWP and 0.1 V/µs slew rate are achieved with only 28 µA total supply current at 5 V, reflecting an optimized speed-power trade-off for low-frequency sensor interfaces.
It operates from a single 2.7–5 V supply or dual ±1.35 V to ±2.5 V supplies, supports input common-mode voltage from −0.2 V to V+ −0.8 V, and features HBM ESD rating of ±2000 V-critical for robustness in portable end-equipment assembly and field use.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad, low-power, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (125 µA/device), higher GBWP (6.4 MHz), but wider input offset (2.5 mV max). | Better for higher-frequency filtering (>100 kHz); less suitable for ultra-low-power battery lifetime targets. | Select when bandwidth >1 MHz is required and power budget allows ≥4× increase over LPV324M/NOPB. |
| MCP6004-E/SL | CMOS input (0.1 pA bias), lower supply current (1 µA/channel), but reduced output drive (1.7 mA) and no bipolar noise advantage. | Preferred for ultra-high-impedance pH or ion-selective electrodes; less optimal for low-noise, low-drift sensor amps. | Choose for femtoampere-input applications where input bias dominates error; avoid when 178 nV/√Hz noise or 16 mA short-circuit drive is needed. |
Compared with TLV2464IDR and MCP6004-E/SL, LPV324M/NOPB uniquely balances sub-30 µA power, 152 kHz bandwidth, bipolar-input noise performance, and robust 16 mA output drive-making it optimal for cost-sensitive, battery-operated sensor signal chains requiring precision and reliability across temperature.

FAQ
What is the maximum supply voltage for LPV324M/NOPB?
The absolute maximum supply voltage for LPV324M/NOPB is 5.5 V, but the recommended operating range is 2.7 V to 5 V. Operating above 5 V risks permanent damage and violates the specified performance envelope. At 5 V, LPV324M/NOPB achieves its full 152 kHz gain-bandwidth product and 28 µA supply current specification.
Does LPV324M/NOPB support true single-supply operation with input down to ground?
Yes, LPV324M/NOPB supports true single-supply operation with input common-mode voltage extending to −0.2 V, enabling direct interfacing with ground-referenced sensors and transducers. This capability is confirmed in the datasheet's DC Electrical Characteristics tables for both 2.7 V and 5 V supplies, and is enabled by its bipolar input stage design.
What package options are available for LPV324M/NOPB?
LPV324M/NOPB is offered in two industry-standard packages: 14-pin SOIC (8.65 mm × 3.91 mm) and 14-pin TSSOP (5.00 mm × 4.40 mm). Both packages share identical pinout, electrical specifications, and thermal resistance values (RθJA = 103.9 °C/W for SOIC, 132.7 °C/W for TSSOP), allowing drop-in layout compatibility.
How does the rail-to-rail output of LPV324M/NOPB improve system performance?
The rail-to-rail output of LPV324M/NOPB delivers V+ −3.5 mV and V− +90 mV swing into 100 kΩ, maximizing usable dynamic range in low-voltage systems. For example, on a 3.3 V supply, this yields >3.2 V peak-to-peak output-preserving >97% of ADC full-scale range and reducing quantization error in 12-bit data acquisition systems.
Is LPV324M/NOPB suitable for driving capacitive loads like piezoelectric sensors?
Yes, LPV324M/NOPB is stable with up to 200 pF capacitive load in unity-gain configuration, as verified in the datasheet's "Capacitive Load Tolerance" section. For heavier loads (e.g., >500 pF), TI recommends using the resistive-isolation circuit shown in Figure 37 of the datasheet to maintain phase margin and prevent oscillation.
