Product details

Overview

LMV324IYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier in TSSOP-14 package, designed for low-voltage portable systems. It operates from 2.7 V to 6 V, draws 145 µA per amplifier, delivers 1 MHz gain bandwidth, and supports extended common-mode input range (V_DD − 0.2 V to V_CC + 0.2 V) at 25 °C - enabling precision signal conditioning in glucose meters and battery-powered medical sensors.

For engineers reviewing the LMV324IYPT datasheet, LMV324IYPT pinout, LMV324IYPT application, or LMV324IYPT equivalent, key selection criteria include its rail-to-rail I/O capability at 2.7–6 V supply, 145 µA quiescent current per channel, 1 MHz GBP, −40 °C to +125 °C automotive-grade temperature range, and TSSOP-14 footprint compatibility with space-constrained PCB layouts.

Technical Context

This quad op-amp uses CMOS input stage architecture to achieve rail-to-rail input common-mode range extending beyond supply rails by ±0.2 V at 25 °C, and rail-to-rail output swing within 15 mV of each rail under 10 kΩ load. Its 1 MHz gain-bandwidth product and 0.45 V/µs slew rate support stable unity-gain buffer and low-frequency active filtering up to ~100 kHz.

Designed for AEC-Q100 qualified automotive applications, LMV324IYPT features 2 kV HBM ESD tolerance, 85 dB typical CMRR at 5 V, and 90 dB typical PSRR - ensuring robust performance in noisy environments such as infotainment sensor interfaces and body control modules where supply ripple and EMI are present.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.7 V to 6 V - enables direct operation from single Li-ion or dual alkaline cells without LDO regulation.
Quiescent Current	145 µA per amplifier - allows four-channel signal conditioning in ultra-low-power wearable devices with multi-day battery life.
Gain Bandwidth	1 MHz - sufficient for anti-aliasing filters, sensor amplification, and DAC output buffering below 100 kHz.
Input Offset Voltage	0.1–3 mV (typ/max @25°C) - supports accurate DC-coupled amplification in medical analog front-ends like glucose meter transimpedance stages.
Common-Mode Range	V_DD − 0.2 V to V_CC + 0.2 V (@25°C) - permits sensing signals referenced to ground or V_CC, including thermistor bridges and current-sense shunts.
Output Drive	±48 mA short-circuit current - drives 2 kΩ loads while maintaining rail-to-rail swing, suitable for driving ADC reference buffers or LED bias circuits.
ESD Rating	2 kV HBM - meets IEC 61000-4-2 Level 2 requirements for handheld diagnostic equipment handling.

Pinout & Package

LMV324IYPT is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP-14), 4.9 mm × 6.4 mm × 1.05 mm body height, with 0.65 mm lead pitch and exposed pad not electrically connected. The package complies with ECOPACK2 environmental standards and supports reflow soldering per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (AMP1)	Accepts feedback or differential signal for first op-amp; requires impedance matching to non-inverting input for offset minimization.
2	Non-inverting Input (AMP1)	Reference node for AMP1; supports common-mode voltages down to V_DD − 0.2 V, enabling ground-referenced sensor interfacing.
3	Output (AMP1)	Rail-to-rail output capable of sourcing/sinking ±48 mA; connects directly to ADC input or low-impedance load without external level-shifting.
4	V_DD (Ground)	Power return for all four amplifiers; must be low-impedance path to system ground plane to maintain PSRR and noise immunity.
5	Non-inverting Input (AMP2)	Second amplifier's high-impedance input; usable for independent sensor channel or reference voltage follower configuration.
6	Inverting Input (AMP2)	Feedback node for AMP2; compatible with resistor networks up to 10 MΩ without significant bias current error.
7	Output (AMP2)	Independent buffered output; shares V_DD/V_CC rails with other channels but electrically isolated signal path.
8	V_CC (Supply)	Positive supply rail for all amplifiers; decoupling capacitor (100 nF X7R) required within 3 mm of pin for stability at 1 MHz GBP.
9	Output (AMP3)	Third channel output; layout symmetry with pins 3 and 7 reduces crosstalk in multi-channel acquisition systems.
10	Inverting Input (AMP3)	Configurable as summing junction or inverting amplifier input; bias current ≤9 nA avoids drift in high-Z sensor networks.
11	Non-inverting Input (AMP3)	Supports rail-to-rail common-mode range - enables direct connection to resistive divider outputs spanning full supply range.
12	Output (AMP4)	Final channel output; routed separately to minimize coupling into sensitive analog inputs on same PCB layer.
13	Inverting Input (AMP4)	Compatible with unity-gain stable compensation; no external compensation required for gains ≥1 with capacitive loads <100 pF.
14	Non-inverting Input (AMP4)	Used for reference buffer or comparator hysteresis input; input capacitance <5 pF avoids phase lag in fast-settling configurations.

Key Features

Feature	Design Value
Rail-to-rail I/O	Enables full-supply-range signal capture and drive without level-shifting circuitry - critical for single-supply data acquisition in portable diagnostics.
145 µA per amplifier	Reduces total quiescent power to 580 µA for quad channel - extends battery life in Class II medical devices operating >100 hours per charge.
AEC-Q100 Grade 2	Qualified for −40 °C to +105 °C ambient operation - supports deployment in automotive cabin sensors and ADAS sub-modules without derating.
1 MHz GBP	Provides stable closed-loop response up to 100 kHz with 10× phase margin - suitable for anti-aliasing filters preceding 200 kSPS SAR ADCs.
Extended Vicm	Accepts input signals 0.2 V beyond rails at 25 °C - eliminates need for external clamping diodes when interfacing with overvoltage-prone transducers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV854IPT	Higher GBP (1.7 MHz), lower input bias current (0.5 pA typ), but higher supply current (220 µA/ch) and narrower Vicm (V_DD to V_CC only).	Better for high-speed filtering or photodiode amps; less suitable for ultra-low-power battery systems requiring extended Vicm.	Select TSV854IPT when bandwidth >1.2 MHz or femtoamp bias is critical; retain LMV324IYPT for cost-sensitive, low-quiescent-power designs with wide common-mode needs.
LMV324IDT	Identical electrical specs but SO-14 package (larger footprint, 125 °C/W R_thJA vs. 100 °C/W for TSSOP14), non-automotive grade (−40 °C to 125 °C, no AEC-Q100).	Suitable for industrial control boards where board area is unconstrained and automotive qualification is unnecessary.	Choose LMV324IDT for legacy SO-14 layouts or non-automotive production; LMV324IYPT preferred for new automotive or space-constrained designs requiring AEC-Q100 compliance.

Compared with TSV854IPT, LMV324IYPT trades 0.7 MHz bandwidth and femtoamp bias for 75 µA lower per-channel current and ±0.2 V extended Vicm - making it superior for battery-powered medical sensors. Against LMV324IDT, it adds AEC-Q100 qualification and 20% better thermal resistance in a 30% smaller footprint, justifying premium for automotive-tier reliability.

FAQ

Is LMV324IYPT pin-compatible with standard SO-14 quad op-amps like LM324?

No. LMV324IYPT uses TSSOP-14 pinout, which matches SO-14 mechanical footprint but has different pin assignments: Pin 4 is V_DD (ground), not V_CC, and Pin 8 is V_CC (supply), not ground. Direct replacement requires PCB redesign or adapter. LMV324IDT (SO-14) shares identical pinout with LM324 but lacks AEC-Q100 qualification.

What is the maximum capacitive load LMV324IYPT can drive without instability?

LMV324IYPT is unity-gain stable with capacitive loads up to 100 pF when properly decoupled (100 nF ceramic capacitor within 3 mm of V_CC pin). For loads >100 pF, a series resistor (10–50 Ω) between output and load restores phase margin; full stability analysis requires evaluating loop gain with actual PCB parasitics and load characteristics.

Does LMV324IYPT support true rail-to-rail output at 2.7 V supply?

Yes. At V_CC = 2.7 V and 25 °C, LMV324IYPT achieves VOL ≤ 90 mV and VOH ≥ 2.6 V into 10 kΩ load - corresponding to <3.4% and <3.3% saturation from respective rails. Output swing degrades slightly at temperature extremes but remains within 100 mV of rails across −40 °C to +125 °C under light loads.

How does the extended common-mode input range benefit sensor interfacing?

The extended Vicm (V_DD − 0.2 V to V_CC + 0.2 V) allows direct connection of sensors whose output exceeds supply rails - such as thermocouples generating ±10 mV or shunt-based current sensors producing negative-going pulses. This eliminates external level-shifting components, reducing BOM count, PCB area, and potential error sources in precision measurement paths.
