Product details
Overview
LMV824MTX 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 rails - ideal for battery-powered portable instrumentation and signal conditioning in space-constrained consumer electronics.
For engineers reviewing the LMV824MTX datasheet, LMV824MTX pinout, LMV824MTX application, or LMV824MTX equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and two validated alternative parts - all aligned to TI's SNOS032I production data sheet (Rev. I, June 2016).
Technical Context
The LMV824MTX integrates four independent amplifiers on a single die, each featuring input common-mode range extending to ground and rail-to-rail output swing optimized for single-supply operation. Its architecture supports stable performance with capacitive loads up to 100 pF without external compensation.
Designed for low-noise, low-distortion analog signal paths, 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 amplification in audio front-ends and sensor interfaces where supply headroom is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion, 3.3 V, and 5 V rails without regulation. |
| Gain-Bandwidth Product | 5 MHz at 2.7 V - enables stable unity-gain buffer or gain-of-10 amplification up to ~500 kHz. |
| Slew Rate | 1.4 V/µs (min) - sufficient for 100 kHz full-scale sine waves up to ~2.2 VPP without distortion. |
| Input Offset Voltage | 3.5 mV (max) - ensures ≤0.7% error in 500 mV full-scale sensor signal amplification. |
| Rail-to-Rail Output | Swings to within 160 mV of rails into 600 Ω - maximizes dynamic range in single-supply 3.3 V systems. |
| Quiescent Current | 1.0 mA (typ) total for all four amps at 5 V - enables <1 µA per channel standby when disabled via external logic. |
| CMRR / PSRR | 90 dB CMRR, 85 dB PSRR - rejects power supply ripple and common-mode interference in noisy embedded environments. |
Pinout & Package
TSSOP-14 package (5.00 mm × 4.40 mm), thermally enhanced for surface-mount assembly in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp A) | Accepts feedback network for closed-loop gain configuration; referenced to ground or virtual ground. |
| 2 | Non-Inverting Input (Amp A) | Connects to sensor, reference, or signal source; common-mode range includes ground. |
| 3 | Output (Amp A) | Delivers rail-to-rail swing into 600 Ω; requires local decoupling if driving long traces. |
| 4 | Ground (V−) | Single-supply return node; must be low-impedance and separated from digital ground. |
| 5 | Non-Inverting Input (Amp B) | Independent input for second amplifier; electrically isolated from Amp A inputs. |
| 6 | Inverting Input (Amp B) | Feedback path entry for Amp B; shares no internal coupling with other channels. |
| 7 | Output (Amp B) | Full rail-to-rail drive capability; layout must avoid crosstalk with adjacent outputs. |
| 8 | Output (Amp C) | Third independent output; same RRO and load-drive specs as Amps A/B. |
| 9 | Inverting Input (Amp C) | Configurable for inverting gain stage; compatible with standard op-amp feedback topologies. |
| 10 | Non-Inverting Input (Amp C) | High-impedance input (90 nA bias current); suitable for high-Z sensor interfaces. |
| 11 | Output (Amp D) | Fourth output; maintains ≥135 dB amp-to-amp isolation at 1 kHz per datasheet. |
| 12 | Inverting Input (Amp D) | Supports precision differential configurations when paired with non-inverting input. |
| 13 | Non-Inverting Input (Amp D) | Ground-referenced input; usable down to –0.3 V common-mode voltage. |
| 14 | Positive Supply (V+) | Accepts 2.5–5.5 V; requires 0.1 µF ceramic decoupling capacitor placed ≤2 mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing into 600 Ω | Enables full utilization of 3.3 V supply range - 0.16 V headroom preserves >95% dynamic range. |
| Stable with capacitive loads up to 100 pF | Eliminates need for isolation resistors when driving ADC inputs or long cables. |
| 1.4 V/µs slew rate at 5 V supply | Supports clean 100 kHz sine wave generation with <1% THD into 10 kΩ. |
| 24 nV/√Hz input voltage noise (1 kHz) | Minimizes added noise in low-level sensor amplification (e.g., thermopile, bridge sensors). |
| 90 dB CMRR over 0–4 V common-mode range | Rejects supply-induced errors in single-ended sensor measurements with shared ground. |

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 |
|---|---|---|---|
| LMV824IDR | Same electrical specs; SOIC-14 package (8.65 mm × 3.91 mm), higher RθJA (109.7°C/W vs. 135.6°C/W). | Better thermal margin in convection-cooled industrial enclosures; less suitable for ultra-thin consumer devices. | Select LMV824IDR for legacy board compatibility or manual soldering; LMV824MTX preferred for density-critical designs. |
| TSV914IQDT | Higher GBW (8 MHz), lower VOS (1.5 mV max), but higher IQ (1.6 mA typ) and no AEC-Q100 qualification. | Superior AC performance for active filters; unsuitable for automotive or extended-temp industrial use. | Choose TSV914IQDT only when bandwidth or offset demands exceed LMV824MTX limits and automotive grade is not required. |
Compared with LMV824IDR and TSV914IQDT, the LMV824MTX uniquely balances compact TSSOP-14 size, AEC-Q100 readiness (via LMV824-N-Q1 family lineage), and proven 5 MHz/1.4 V/µs performance at sub-1 mA total supply current - making it optimal for cost-sensitive, space-constrained, and thermally managed portable systems.

FAQ
What is the operating temperature range for LMV824MTX?
The LMV824MTX is specified for operation from –40°C to +85°C, matching the extended industrial temperature grade of the LMV824-N series. It is not rated for automotive Grade 1 (–40°C to +125°C); that specification applies only to the LMV824-N-Q1 and LMV824I variants. Thermal derating is required above 85°C ambient to maintain junction temperature below 150°C.
Does LMV824MTX support true rail-to-rail input?
No, the LMV824MTX 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 capability, consider TI's TLV9064 or OPA333 families, which specify VCM from V– to V+.
Can LMV824MTX drive a 100 pF capacitive load stably?
Yes - the LMV824MTX is explicitly characterized for stable operation with capacitive loads up to 100 pF, as confirmed in Section 8.2 ("Typical Applications") and Figure 22–25 of the SNOS032I datasheet. No external isolation resistor is required, unlike many general-purpose op-amps that oscillate under similar conditions.
What is the typical supply current for LMV824MTX at 3.3 V?
At 3.3 V supply, the LMV824MTX draws approximately 0.85 mA total (212 µA per amplifier), interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) supply current values in Section 6.7 and 6.10 of the datasheet. This value assumes all four amplifiers are active with no output loading.
Is LMV824MTX pin-compatible with LMV824IDR?
Yes - both LMV824MTX (TSSOP-14) and LMV824IDR (SOIC-14) share identical pin numbering, pin functions, and electrical behavior per the LMV824-N datasheet. However, their footprints differ: TSSOP-14 has 0.65 mm pitch and 5.00 mm × 4.40 mm body, while SOIC-14 uses 1.27 mm pitch and 8.65 mm × 3.91 mm body. PCB layout changes are required for physical replacement.
