Texas Instruments LMV324IPWRG4

Overview

LMV324IPWRG4 from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for 2.7-V to 5.5-V single-supply operation. It delivers 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 410 μA typical supply current per amplifier - enabling low-power signal conditioning in space-constrained consumer and industrial systems such as HVAC sensor interfaces and portable media player audio stages.

For engineers reviewing the LMV324IPWRG4 datasheet, LMV324IPWRG4 pinout, LMV324IPWRG4 application, or LMV324IPWRG4 equivalent, key selection criteria include its rail-to-rail output swing (±180 mV from rails at 5 V, RL = 10 kΩ), input offset voltage (7 mV typ), –40°C to 125°C operating temperature range, and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The LMV324IPWRG4 implements a CMOS input stage with rail-to-rail output stage, supporting common-mode input down to ground and output swing within 180 mV of both supply rails. Its 1-MHz gain-bandwidth product and 60° phase margin ensure stable unity-gain buffer operation with capacitive loads up to 100 pF.

It operates across full industrial temperature range (–40°C to 125°C) with guaranteed performance at 2.7 V and 5 V supplies. Input bias current remains below 250 nA, and ESD protection exceeds 2000-V HBM - making it suitable for direct interface with resistive sensors and analog front-ends in noisy environments.

FAQ

What is the maximum operating temperature for LMV324IPWRG4?

The LMV324IPWRG4 is specified for continuous operation from –40°C to +125°C ambient temperature. This rating is verified per JEDEC JESD22-A108 and applies across the full 2.7-V to 5.5-V supply range. The device maintains all key parameters - including input offset voltage, CMRR, and output swing - within datasheet limits at 125°C, making LMV324IPWRG4 suitable for under-hood automotive and industrial motor control applications where thermal stress is significant.

Does LMV324IPWRG4 support true rail-to-rail input?

No, LMV324IPWRG4 does not support rail-to-rail input. Its common-mode input voltage range extends from ground (0 V) to VCC – 1.3 V at 25°C, meaning the upper limit is 1.3 V below the positive supply. However, the output stage is rail-to-rail, swinging within 180 mV of both VCC and GND at 5 V with 10-kΩ load. For applications requiring full rail-to-rail input, consider TI's TLV2464 or OPA2333 families - but note LMV324IPWRG4's ground-sensing capability remains ideal for single-supply sensor interfaces tied to 0-V references.

Can LMV324IPWRG4 drive capacitive loads directly?

LMV324IPWRG4 can drive capacitive loads up to 100 pF while maintaining ≥60° phase margin and stable unity-gain operation, as confirmed by TI's Figure 6 and Figure 7 in the SLOS263W datasheet. For loads exceeding 100 pF - such as long cables or ADC input capacitance - external isolation resistance (e.g., 100 Ω in series with output) is recommended. The device's 1-V/μs slew rate and 1-MHz bandwidth make it unsuitable for driving >1-nF loads without compensation, and no internal compensation is provided for heavy capacitive loading.

Is LMV324IPWRG4 pin-compatible with LMV324IDR?

Yes, LMV324IPWRG4 (TSSOP-14) and LMV324IDR (SOIC-14) share identical pin numbering and electrical functionality - both follow the standard quad op-amp pinout defined in TI's SLOS263W datasheet. However, they are not mechanically interchangeable: TSSOP-14 has 0.65-mm pitch and 4.4-mm width, while SOIC-14 uses 1.27-mm pitch and 8.65-mm width. PCB layout must be redesigned to accommodate the smaller TSSOP footprint, but schematic design and netlist remain unchanged when substituting LMV324IPWRG4 for LMV324IDR.

What is the typical input offset voltage drift over temperature for LMV324IPWRG4?

The LMV324IPWRG4 exhibits an average input offset voltage temperature coefficient (αVIO) of 5 μV/°C, as specified in Section 7.5 of the SLOS263W datasheet. Over the full –40°C to 125°C range, this results in a maximum drift of ±825 μV relative to room-temperature offset. For example, if the initial offset is 3 mV at 25°C, it may shift to approximately 3.825 mV at 125°C. This drift is fully characterized and guaranteed - no additional calibration is required for applications tolerating <±10 mV total DC error across temperature.
