Product details

Overview

LMV824Q1MT/NOPB from Texas Instruments is a quad, rail-to-rail output (RRO), low-voltage (2.5 V to 5.5 V), low-power operational amplifier qualified for automotive applications per AEC-Q100 Grade 1 (−40°C to +125°C). It delivers 5 MHz gain-bandwidth product at 2.7 V, 1.4 V/µs slew rate, 3.5 mV max input offset voltage, and 220 µA per amplifier supply current - enabling precision signal conditioning in space-constrained automotive sensor interfaces and body control modules.

For engineers reviewing the LMV824Q1MT/NOPB datasheet, LMV824Q1MT/NOPB pinout, LMV824Q1MT/NOPB application, or LMV824Q1MT/NOPB equivalent, key selection criteria include its extended temperature operation, RRO swing into 600 Ω (160 mV from rail), CMRR of 90 dB, PSRR of 85 dB, and TSSOP-14 package compatibility with automotive PCB layout standards.

Technical Context

The LMV824Q1MT/NOPB implements a complementary input stage enabling rail-to-rail output swing while maintaining stable performance with capacitive loads up to several hundred pF. Its input common-mode range includes ground (−0.3 V at 5 V supply), supporting single-supply operation in battery-powered systems.

Designed for low-noise, low-distortion amplification, it achieves 24 nV/√Hz input voltage noise at 1 kHz and 0.01% THD at 1 kHz with 4.1 V_PP output into 10 kΩ - making it suitable for analog front-ends in automotive infotainment audio paths and sensor signal chains requiring high fidelity at minimal quiescent power.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.5 V to 5.5 V - supports direct connection to 3.3 V and 5 V rails, including automotive 5 V domains with margin.
Gain-Bandwidth Product	5 MHz at 2.7 V - enables stable unity-gain buffer or gain-of-10 configurations up to ~500 kHz without phase margin degradation.
Slew Rate	1.4 V/µs min at 5 V - sufficient for 100 kHz full-scale sine wave output with ≤1 V_PP at 5 V supply.
Input Offset Voltage	3.5 mV max - ensures ≤0.7% error in 0–5 V sensor scaling circuits without trimming.
Quiescent Current	1.0 mA typical (250 µA per amplifier) - allows four-channel operation within 1.5 mA budget for always-on vehicle subsystems.
Rail-to-Rail Output	Swings to within 160 mV of rails into 600 Ω - preserves dynamic range in low-voltage ADC driver stages with heavy loading.
CMRR / PSRR	90 dB / 85 dB - rejects supply ripple and common-mode interference in noisy automotive environments.

Pinout & Package

TSSOP-14 package (5.00 mm × 4.40 mm, 0.65 mm pitch), thermally enhanced for automotive under-hood operation.

Pin/Terminal	Circuit Role	Design Meaning
1, 5, 9, 13	Inverting Input (−IN)	Four independent inverting inputs - each requires matched trace length and impedance for multi-channel feedback stability.
2, 6, 10, 14	Non-Inverting Input (+IN)	Four independent non-inverting inputs - referenced to local ground or bias network for sensor interface.
3, 7, 11, 12	Output	Four buffered outputs - capable of sourcing/sinking ≥20 mA, enabling direct LED drive or DAC output buffering.
4	V−	Negative supply pin - tied to GND in single-supply mode; must be decoupled with 100 nF ceramic near pin.
8	V+	Positive supply pin - accepts 2.5–5.5 V; requires dedicated 100 nF + 1 µF parallel decoupling for EMI suppression.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for −40°C to +125°C operation with lifetime reliability testing - suitable for engine control, HVAC, and ADAS sensor nodes.
Rail-to-rail output into 600 Ω	Delivers >4.8 V swing at 5 V supply with 160 mV headroom - maximizes ADC utilization in 12-bit+ data acquisition systems.
Stable with capacitive loads	Remains unconditionally stable driving ≥100 pF - eliminates need for isolation resistors in LCD bias or filter output stages.
Low input bias current (≤100 nA)	Minimizes voltage error across high-impedance sensor bridges (e.g., thermistors, RTDs) without external compensation.
1 µV/°C input offset drift	Ensures <±0.5 mV total offset shift over full automotive temperature range - critical for precision current sensing.

FAQ

What is the maximum operating temperature for LMV824Q1MT/NOPB?

The LMV824Q1MT/NOPB is rated for continuous operation from −40°C to +125°C per AEC-Q100 Grade 1 requirements. This specification is validated across process corners and lifetime reliability stress tests, making it suitable for under-hood and cabin applications where ambient temperatures exceed 105°C. The device maintains all electrical parameters within datasheet limits across this full range.

Does LMV824Q1MT/NOPB support true single-supply operation with input voltages down to ground?

Yes, LMV824Q1MT/NOPB supports true single-supply operation: its input common-mode voltage range extends to −0.3 V at 5 V supply, meaning it accepts inputs at or slightly below ground potential. This enables direct interfacing with grounded sensors (e.g., thermocouples, shunt-based current monitors) without level-shifting circuitry - a key advantage in automotive battery monitoring and chassis-ground-referenced signal chains.

What is the recommended power supply decoupling for LMV824Q1MT/NOPB in automotive PCB layouts?

TI recommends placing a 100 nF X7R ceramic capacitor (0603 or 0805) within 2 mm of each V+ (Pin 8) and V− (Pin 4) pin, plus a bulk 1 µF tantalum or ceramic capacitor near the TSSOP-14 footprint. This dual-stage decoupling suppresses high-frequency switching noise from nearby ECUs and ensures stable operation during load-dump transients - critical for maintaining PSRR >85 dB in noisy 12 V vehicle electrical systems.

Can LMV824Q1MT/NOPB drive a 600 Ω load while maintaining rail-to-rail output swing?

Yes, LMV824Q1MT/NOPB is specified to deliver rail-to-rail output swing into 600 Ω loads: at 5 V supply, it achieves ≥4.75 V high-side and ≤0.25 V low-side swing (i.e., within 160 mV of each rail). This capability is verified across temperature and process variations, enabling direct interface with legacy analog inputs, transmission line terminations, and low-impedance ADC drivers without external buffers.

Is LMV824Q1MT/NOPB pin-compatible with other quad op amps in TSSOP-14 packages?

LMV824Q1MT/NOPB uses the industry-standard TSSOP-14 pinout for quad op amps (Pin 1 = −IN A, Pin 2 = +IN A, Pin 3 = OUT A, etc.), matching TI's own LMV824-N, LMV824I, and compatible devices from STMicroelectronics (TSV914) and Microchip (MCP6004). However, electrical differences (e.g., bandwidth, drive strength) require verification in final schematic capture - it is not a drop-in replacement without design review.
