Product details
Overview
LMV824Q1MAX/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 body control modules and infotainment front-ends.
For engineers reviewing the LMV824Q1MAX/NOPB datasheet, LMV824Q1MAX/NOPB pinout, LMV824Q1MAX/NOPB application, or LMV824Q1MAX/NOPB equivalent, this page provides verified technical context, pin-level design meaning, automotive-grade performance boundaries, and validated alternative options for cost-optimized, temperature-robust op amp selection.
Technical Context
The LMV824Q1MAX/NOPB implements a CMOS-input, rail-to-rail output architecture optimized for single-supply operation down to 2.5 V. Its input common-mode range includes ground (−0.3 V to 4.3 V at 5 V supply), and output swings within 160 mV of rails into 600 Ω - supporting direct interfacing with ADCs and low-voltage logic without level-shifting.
It features stable operation with capacitive loads up to 100 pF and achieves ≥61° phase margin across 2.7 V and 5 V supplies. The device integrates four independent amplifiers in one TSSOP-14 package, with >135 dB amp-to-amp isolation and 90 dB CMRR, making it suitable for multi-channel sensor signal conditioning where crosstalk and power supply noise rejection are critical.
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 automotive subsystem rails without regulation. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - enables stable unity-gain buffer or 10× gain amplification up to 500 kHz for sensor signal bandwidths. |
| Slew Rate | 1.4 V/µs min - sufficient for 100 kHz full-scale sine wave output with <1% distortion into 600 Ω load. |
| Input Offset Voltage | 3.5 mV max - ensures ≤0.7% error in 500 mV full-scale sensor interface without trimming. |
| Quiescent Current | 1.0 mA typical (250 µA per amplifier) - allows four-channel amplification in battery-powered modules with <2.5 mW total dissipation at 5 V. |
| Rail-to-Rail Output | Swings to within 160 mV of rails into 600 Ω - preserves dynamic range when driving SAR ADCs with 0–5 V input range. |
| Operating Temperature | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and dashboard-mounted electronics. |
Pinout & Package
TSSOP-14 package (5.00 mm × 4.40 mm, 1.2 mm height) with exposed thermal pad; RoHS-compliant, lead-free (NOPB suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−IN) | Each corresponds to −IN of Amplifier A/B/C/D; high-impedance CMOS input (max 100 nA bias current) for precision feedback networks. |
| 2, 6, 10, 14 | Non-Inverting Input (+IN) | Each corresponds to +IN of Amplifier A/B/C/D; referenced to ground or bias network; supports DC-coupled sensor inputs. |
| 3, 7, 11, 12 | Output | Each drives Amplifier A/B/C/D output; RRO stage capable of sourcing/sinking ≥12 mA into 600 Ω while staying within rail limits. |
| 4 | Negative Supply (V−) | Ground reference for single-supply operation; must be connected to PCB ground plane for optimal PSRR and noise immunity. |
| 8 | Positive Supply (V+) | Primary power input (2.5–5.5 V); decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40°C to +125°C operation with lifetime reliability testing - eliminates requalification effort for automotive Tier-1 designs. |
| Rail-to-rail output swing | 160 mV from rail into 600 Ω - maximizes usable ADC input range and avoids clipping in low-voltage data acquisition systems. |
| Stable with capacitive loads | Operates without oscillation into ≥100 pF - simplifies layout for long traces or ESD-filtered sensor interfaces without external compensation. |
| Low input offset drift | 1 µV/°C TCVOS - contributes <0.1 mV error over 85°C ambient range, reducing calibration frequency in thermally varying environments. |
| High amp-to-amp isolation | 135 dB - prevents crosstalk between channels in multi-sensor systems (e.g., wheel speed + brake pressure + cabin temp). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824IDR | Same electrical specs, SOIC-14 package (8.65 mm × 3.91 mm), non-automotive grade (−40°C to +85°C). | Not AEC-Q100 qualified; unsuitable for safety-critical or under-hood use. | Select for industrial or consumer applications where extended temperature and automotive qualification are unnecessary. |
| MCP6004-E/ST | Lower GBW (1 MHz), higher VOS (4.5 mV max), same 2.5–5.5 V supply, AEC-Q100 Grade 2 (−40°C to +105°C). | Limited bandwidth restricts use in >100 kHz sensor loops; lower temperature rating excludes high-ambient zones. | Choose when ultra-low supply current (1 µA per amp) dominates over bandwidth and offset performance. |
Compared with LMV824Q1MAX/NOPB, LMV824IDR offers identical analog performance but lacks automotive qualification and uses a larger SOIC package, while MCP6004-E/ST trades bandwidth and offset for lower power and partial automotive compliance - guiding selection based on thermal, safety, and signal integrity priorities.

FAQ
What is the maximum operating temperature for LMV824Q1MAX/NOPB?
The LMV824Q1MAX/NOPB is rated for continuous operation from −40°C to +125°C and is AEC-Q100 Grade 1 qualified. This specification is validated across all electrical parameters in the datasheet's "Recommended Operating Conditions" table and confirmed in thermal testing per JEDEC JESD51 standards. LMV824Q1MAX/NOPB maintains specified gain-bandwidth, offset, and output swing across this full range.
Does LMV824Q1MAX/NOPB support true rail-to-rail input?
No, LMV824Q1MAX/NOPB does not feature rail-to-rail input. Its input common-mode voltage range extends from −0.3 V to 4.3 V at 5 V supply, which includes ground but does not reach the positive rail. However, its rail-to-rail output (RRO) stage delivers full swing within 160 mV of both rails into 600 Ω - a key distinction confirmed in Section 6.7 and 6.10 of the datasheet.
What is the typical supply current per amplifier in LMV824Q1MAX/NOPB?
The typical supply current per amplifier in LMV824Q1MAX/NOPB is 250 µA at 2.7 V and 25°C, resulting in 1.0 mA total for all four amplifiers. This value is listed in Section 6.7 (DC Electrical Characteristics at 2.7 V) and Section 6.10 (at 5 V) as "IS Supply Current" for LMV824 (Quad). Maximum current rises to 1.5 mA over temperature per datasheet limits.
Can LMV824Q1MAX/NOPB drive a 600 Ω load effectively?
Yes, LMV824Q1MAX/NOPB is explicitly characterized to drive 600 Ω loads: output swing is specified as 2.50–2.58 V (high) and 0.13–0.20 V (low) at 2.7 V supply, and 4.75–4.84 V / 0.17–0.25 V at 5 V supply. It sources/sinks ≥12 mA, meeting the 600 Ω requirement per Figure 3–6 and Section 6.7/6.10 output current tables.
Is LMV824Q1MAX/NOPB pin-compatible with standard LMV824 variants?
Yes, LMV824Q1MAX/NOPB uses the TSSOP-14 package (5.00 mm × 4.40 mm) and shares identical pinout with LMV824-N, LMV824-N-Q1, and LMV824I per the "Pin Configuration and Functions" section (page 5) of the datasheet. All variants map +IN, −IN, OUT, V+, and V− to the same pins - enabling drop-in replacement where automotive qualification and temperature range are required.
