Product details
Overview
LMV824MT from Texas Instruments is a quad, rail-to-rail output (RRO), low-voltage (2.5 V to 5.5 V), low-power operational amplifier with 5 MHz gain-bandwidth product, 1.4 V/µs slew rate, and 3.5 mV max input offset voltage. It operates across –40°C to +85°C and drives 600 Ω loads within 160 mV of supply rails - ideal for battery-powered portable instrumentation and signal conditioning in space-constrained consumer electronics.
For engineers reviewing the LMV824MT datasheet, LMV824MT pinout, LMV824MT application, or LMV824MT equivalent, key selection criteria include its RRO output swing into 600 Ω, 220 µA per amplifier quiescent current at 2.7 V, 90 dB CMRR, 85 dB PSRR, and stable performance with capacitive loads - all validated for single-supply operation down to 2.5 V.
Technical Context
The LMV824MT integrates four independent amplifiers on a single die, each featuring input common-mode range extending to ground and rail-to-rail output stage capable of sourcing/sinking ≥12 mA. Its internal architecture supports unity-gain stability with capacitive loads up to several hundred pF without external compensation.
Designed for low-noise, low-distortion signal amplification, it delivers 24 nV/√Hz input voltage noise at 1 kHz and 0.01% THD at 1 kHz with 4.1 VPP output into 10 kΩ - enabling high-fidelity analog front-ends in audio and sensor interfaces where power efficiency and precision coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct integration into 3.3 V and 5 V systems, including single-cell Li-ion and dual-cell alkaline supplies. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - supports stable closed-loop gain configurations up to ~50× at 100 kHz for sensor amplification and active filtering. |
| Slew Rate | 1.4 V/µs min - ensures faithful reproduction of 100 kHz full-scale sine waves with ≤1% distortion in unity-gain buffer applications. |
| Input Offset Voltage | 3.5 mV max - limits DC error to <±0.7% of full-scale when amplifying ±500 mV sensor outputs with gain = 10. |
| Quiescent Current | 1.0 mA typical (250 µA per amp) at 5 V - allows four-channel amplification in always-on circuits with <10 mW total dissipation. |
| Rail-to-Rail Output | Swings to within 160 mV of rails at 600 Ω load - maximizes dynamic range in 3.3 V ADC driver stages without level-shifting circuitry. |
| CMRR / PSRR | 90 dB / 85 dB - rejects supply ripple and common-mode interference in noisy mixed-signal PCB environments. |
Pinout & Package
TSSOP-14 package (5.00 mm × 4.40 mm), thermally enhanced for surface-mount assembly in compact portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−IN) | Each corresponds to one of four op-amp channels; accepts differential input signals referenced to ground or virtual ground. |
| 2, 6, 10, 14 | Non-Inverting Input (+IN) | Independent high-impedance inputs for each amplifier; supports biasing networks and sensor interface topologies. |
| 3, 7, 11, 12 | Output (OUT) | Capable of sourcing/sinking ≥12 mA; rail-to-rail swing enables direct connection to SAR ADC inputs or low-voltage logic buffers. |
| 4 | Negative Supply (V−) | Ground reference for single-supply operation; must be connected to system GND or negative rail in split-supply configurations. |
| 8 | Positive Supply (V+) | Primary power input; decoupling capacitor (0.1 µF) required within 5 mm for stability and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers >95% of full-scale output swing into 600 Ω loads - eliminates need for level-shifting in 3.3 V data acquisition systems. |
| Low quiescent current | 250 µA per amplifier at 2.7 V - extends battery life in portable medical monitors and handheld test equipment. |
| Stable with capacitive loads | Maintains phase margin >61° with up to 200 pF load capacitance - simplifies layout for LCD biasing and piezo driver circuits. |
| Extended temperature range | Specified from –40°C to +85°C - suitable for industrial control I/O modules and automotive cabin electronics (non-Q1 grade). |
| High PSRR/CMRR | 85 dB PSRR and 90 dB CMRR at DC - suppresses coupling from digital switching noise and power rail fluctuations in mixed-signal SoC peripherals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher 6.4 MHz GBW, 2.5 V/µs slew rate, but 550 µA per amp supply current - 2.2× higher than LMV824MT. | Better bandwidth for active filters; less suitable for ultra-low-power always-on monitoring. | Choose TLV2464IDR when speed outweighs power budget; LMV824MT preferred for sub-1 mA total quiescent current. |
| LMV324DT | Lower 1 MHz GBW, 0.45 V/µs slew rate, 3.5 mV VOS, but only 210 µA per amp - slightly lower power than LMV824MT. | Cost-optimized for non-critical general-purpose amplification; insufficient for audio or fast sensor response. | Choose LMV324DT for cost-sensitive, low-speed applications; LMV824MT when 5 MHz GBW and 1.4 V/µs are required. |
Compared with TLV2464IDR and LMV324DT, the LMV824MT uniquely balances 5 MHz bandwidth, rail-to-rail output, and sub-250 µA per amplifier quiescent current - making it optimal for portable instrumentation where both precision and battery life are critical.

FAQ
What is the maximum operating temperature for the LMV824MT?
The LMV824MT is specified for operation from –40°C to +85°C ambient temperature. It is not the automotive-grade Q1 variant (LMV824-N-Q1), which extends to +125°C. Thermal derating applies above 85°C; junction temperature must remain below 150°C under all conditions using the device's θJA = 135.6°C/W (TSSOP-14 package).
Does the LMV824MT support true rail-to-rail input?
No, the LMV824MT features rail-to-rail *output* only. Its input common-mode voltage range extends to ground (–0.3 V at 5 V supply) but does not reach the positive rail - maximum VCM is 4.3 V at 5 V supply. For true rail-to-rail input, consider TI's TLV2464 or OPA333 families.
Can the LMV824MT drive a 10 kΩ load with full rail-to-rail swing?
Yes. At 5 V supply and 25°C, the LMV824MT output swings to within 150 mV of each rail into a 10 kΩ load - achieving >4.85 V high and <0.15 V low. This meets typical 16-bit ADC input requirements without external level-shifting circuitry.
Is the LMV824MT pin-compatible with other quad op-amps in TSSOP-14?
The LMV824MT uses standard TSSOP-14 pinout per TI's LMV824-N family (pin 1 = −IN of Amp A, pin 2 = +IN of Amp A, ..., pin 8 = V+, pin 4 = V−). It is pin-compatible with LMV824IDR, LMV824IPW, and LMV824I - but not with generic quad op-amps like LM324 or TL074 due to differing channel mapping and supply pin locations.
What decoupling is recommended for stable operation of the LMV824MT?
A 0.1 µF ceramic capacitor placed between pin 8 (V+) and pin 4 (V−), located within 5 mm of the device, is mandatory. For systems with noisy supplies, add a 4.7 µF tantalum or ceramic bulk capacitor near the TSSOP-14 footprint. Avoid shared vias between decoupling paths for multiple LMV824MT units on the same board.
