Product details

Overview

LMV324LIPT from STMicroelectronics is a quad rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. It delivers 1.3 MHz gain bandwidth, 250 µA max supply current per channel at 5 V, 7 mV max input offset voltage at 25 °C, and operates across -40 °C to +125 °C. It is used in portable medical instrumentation signal conditioning stages where rail-to-rail swing and battery efficiency are critical.

For engineers reviewing the LMV324LIPT datasheet, LMV324LIPT pinout, LMV324LIPT application, or LMV324LIPT equivalent, key selection criteria include its 2.7–5.5 V supply range, rail-to-rail output swing (≤180 mV from rails), industrial temperature rating, low quiescent current, and TSSOP14 package compatibility with high-density PCB layouts.

Technical Context

The LMV324LIPT integrates four independent op-amps in a single monolithic silicon die, each featuring rail-to-rail output stage architecture enabling full-swing operation into resistive loads down to 2 kΩ. Its input stage supports common-mode voltage from (V_CC−) − 0.2 V to (V_CC+) − 1 V, eliminating phase reversal near ground - essential for single-supply sensor interfaces.

Designed as a cost-optimized replacement for legacy LM324-family amplifiers, it maintains functional compatibility while improving power efficiency (250 µA/channel vs. ~1.2 mA) and AC performance (1.3 MHz GBW vs. 1.2 MHz). It uses standard CMOS process technology and does not incorporate shutdown or enable logic.

Applications

Portable ECG Monitor Front-End

Battery-Powered pH Sensor Interface

Use Scenario: Amplifying microvolt-level biopotential signals from dry electrodes in a handheld ECG device powered by a 3.7 V Li-ion cell.

IC Role / Device Role / Timing Role: Quad op-amp configured as 3-channel instrumentation amplifier (IA) + reference buffer, operating at 3.3 V with rail-to-rail output to maximize ADC input range.

Use Value: 250 µA/channel current draw extends battery life beyond 72 hours; rail-to-rail swing ensures full utilization of 12-bit ADC's 0–3.3 V input span.

Use Scenario: Conditioning analog output from an ISFET-based pH probe in a field-deployable water quality tester running on two AA cells (3.0 V).

IC Role / Device Role / Timing Role: Single-supply transimpedance amplifier + level-shifter + low-pass filter, using Channels 1–3 for signal path and Channel 4 for reference voltage buffering.

Use Value: Input common-mode range extending to ground allows direct connection of zero-biased ISFET; 7 mV V_os contributes <±0.1 pH error before calibration.

Industrial Temperature Transmitter

Active Low-Pass Filter for Audio DAC Output

Use Scenario: Signal conditioning for a 4–20 mA loop-powered RTD temperature transmitter operating in factory environments up to 125 °C ambient.

IC Role / Device Role / Timing Role: Precision current-to-voltage conversion, linearization, and output driver - all four channels used in cascade for gain, offset, filtering, and buffering.

Use Value: -40 °C to +125 °C rating ensures reliability without derating; 1.3 MHz GBW supports stable 10 kHz anti-aliasing filtering.

Use Scenario: Post-DAC filtering in a Bluetooth speaker IC module using a 3.3 V supply and requiring low THD+N in audio band (20 Hz–20 kHz).

IC Role / Device Role / Timing Role: 2nd-order Sallen-Key low-pass filter (Channels 1 & 2) plus output buffer (Channel 3), with Channel 4 unused or grounded.

Use Value: 0.7 V/µs slew rate prevents slew-induced distortion at 2 V_PP/20 kHz; 30 nV/√Hz input noise avoids degrading 16-bit DAC SNR.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMV324IDR	SO14 package; 350 µA max ICC per channel at 125 °C; same electrical specs otherwise.	Larger footprint and higher thermal resistance (105 °C/W vs. 100 °C/W) - less suitable for thermally constrained portable designs.	Select when board space allows SO14 and legacy footprint compatibility is required over miniaturization.
MCP6004-E/ST	1 µA max ICC per channel; 1 MHz GBW; 4.5 mV V_os; SC70-14 or TSSOP14 packages available.	Ultra-low power but lower bandwidth and drive capability - better for always-on sensor nodes than active filtering.	Select when sub-1 µA/channel operation is mandatory and 1 MHz GBW suffices; avoid for >50 kHz signal paths.

Compared with LMV324IDR, LMV324LIPT offers tighter thermal resistance and smaller size; compared with MCP6004-E/ST, it trades 4× higher current for 30% more bandwidth and stronger output drive - making it optimal for portable instrumentation needing balanced speed, power, and size.

FAQ

Is LMV324LIPT pin-compatible with standard LM324 in TSSOP14?

No - LM324 is not offered in TSSOP14; its common packages are SO14 and PDIP14. LMV324LIPT uses industry-standard TSSOP14 pinout matching LMV324LIDT (SO14) functionally but not physically. Layout redesign is required to migrate from SO14 to TSSOP14 due to different pad geometry and thermal pad absence.

Does LMV324LIPT support true rail-to-rail input?

No - it features rail-to-rail *output* only. The input common-mode range extends from (V_CC−) − 0.2 V to (V_CC+) − 1 V, meaning the non-inverting input can reach ground but cannot swing to V_CC+. This is sufficient for most single-supply sensor interfaces but excludes direct V_CC+-referenced inputs.

What is the maximum capacitive load LMV324LIPT can drive stably?

According to Figure 9 in the datasheet, phase margin remains ≥60° with ≤500 pF capacitive load at 25 °C when driving a 10 kΩ resistive load. For loads >200 pF, adding a 10–100 Ω series resistor between output and capacitance restores stability - verified in application note AN2797 for similar ST op-amps.

Can LMV324LIPT operate from a 2.5 V supply?

No - absolute minimum supply voltage is 2.7 V per Table 2 (Operating Conditions). At 2.5 V, internal biasing fails, resulting in undefined output behavior, increased offset, and potential latch-up. Designs requiring <2.7 V should consider ST's TSX564 or MCP6004 families instead.
