Product details
Overview
LPV324IPWG4 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 +125°C operating temperature range. It delivers rail-to-rail output swing (VCC+ − 3.5 mV / VCC− + 90 mV at 100-kΩ load) and supports general-purpose signal conditioning in space-constrained, battery-powered sensor interfaces.
For engineers reviewing the LPV324IPWG4 datasheet, LPV324IPWG4 pinout, LPV324IPWG4 application, or LPV324IPWG4 equivalent, key selection criteria include its ultra-low quiescent current, guaranteed operation over automotive-grade temperature range, rail-to-rail output capability at 2.7-V supply, and compatibility with capacitive loads up to 1000 pF without instability.
Technical Context
The LPV324IPWG4 implements a CMOS input stage with rail-to-rail output stage, 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.
It achieves stable unity-gain operation with capacitive loads up to 1000 pF and exhibits no crossover distortion. The device is characterized across −40°C to +125°C and meets JESD 78 Class II latch-up performance (>100 mA) and JESD 22 ESD ratings (2 kV HBM, 200 V MM, 1 kV CDM).

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 |
|---|---|---|---|
| LPV324DR | SOIC-14 package; same electrical specs but 86°C/W θJA vs. 113°C/W for PW; rated only to 85°C ambient. | Preferred for through-hole prototyping or legacy board designs; unsuitable for under-hood or sealed high-temp enclosures. | Select LPV324DR only if SOIC footprint is fixed and temperature requirement ≤85°C. |
| MCP6004-E/ST | Higher supply current (1 µA/channel), wider GBW (1 MHz), but only rated to 125°C with derated parameters; no 2.7-V min spec. | Better for higher-speed filtering but lacks guaranteed 2.7-V operation and rail-to-rail output at low supply. | Choose MCP6004-E/ST only when bandwidth >200 kHz is required and supply ≥3.3 V is assured. |
Compared with LPV324DR and MCP6004-E/ST, the LPV324IPWG4 uniquely combines automotive-grade temperature range, guaranteed 2.7-V operation, rail-to-rail output at ultra-low current, and TSSOP-14 footprint-making it optimal for miniaturized, battery-powered, high-reliability analog signal chains.

FAQ
What is the maximum capacitive load the LPV324IPWG4 can drive without oscillation?
The LPV324IPWG4 is stable with capacitive loads up to 1000 pF, as confirmed in the datasheet Figure 14 and 15 frequency response plots. This eliminates the need for series isolation resistors when driving typical SAR ADC input capacitances (10–30 pF) or longer PCB traces, simplifying layout and preserving signal integrity in LPV324IPWG4-based designs.
Does the LPV324IPWG4 support true rail-to-rail input operation?
No-the LPV324IPWG4 features rail-to-rail *output* swing but has a limited input common-mode range of −0.2 V to VCC+ − 0.8 V. It does not accept inputs at the positive rail. For true rail-to-rail input capability, consider TI's TLV9004 or similar families. The LPV324IPWG4 remains ideal for ground-referenced or mid-supply sensor interfaces where this limitation is acceptable.
What is the supply current of the LPV324IPWG4 at 2.7 V and 25°C?
At 2.7 V and 25°C, the LPV324IPWG4 draws 16 μA typical supply current for all four channels (4 μA per channel), as specified in the "2.7-V electrical characteristics" table on page 5 of the datasheet. This ultra-low current enables multi-year operation in coin-cell–powered devices and aligns with the LPV324IPWG4's role in energy-constrained systems.
Is the LPV324IPWG4 pin-compatible with standard SOIC-14 quad op-amps like the LM324?
No-the LPV324IPWG4 uses the industry-standard TSSOP-14 pinout (PW package), which matches the SOIC-14 pin assignment (1OUT, 1IN−, 1IN+, VCC+, etc.) but is not physically interchangeable due to different package dimensions and pitch. While electrically pin-compatible with LPV324D/DR variants, the LPV324IPWG4 requires TSSOP-14 footprint and reflow profile-not SOIC hand-soldering.
What is the input offset voltage specification for the LPV324IPWG4 over temperature?
The LPV324IPWG4 has a maximum input offset voltage of 11 mV across the full −40°C to +125°C operating range, as stated in the "5-V electrical characteristics" table on page 6. At 25°C, typical VIO is 1.5 mV, with an average temperature coefficient of 4 µV/°C-enabling predictable drift compensation in LPV324IPWG4-based precision sensor amplifiers.
