Product details

Overview

LMV824NDGVR from Texas Instruments (formerly National Semiconductor) is a quad, rail-to-rail output, low-voltage operational amplifier optimized for battery-powered portable electronics. It delivers 5 MHz gain-bandwidth, 1.4 V/µs minimum slew rate, and 220 µA/amplifier quiescent current at 2.7 V, enabling high-speed signal conditioning in space-constrained, low-power systems such as PCMCIA modem cards and handheld audio interfaces.

For engineers reviewing the LMV824NDGVR datasheet, LMV824NDGVR pinout, LMV824NDGVR application, or LMV824NDGVR equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative op amps with documented functional trade-offs for low-voltage, RRO, 5 MHz-class designs.

Technical Context

The LMV824NDGVR integrates four independent amplifiers in a single TSSOP-14 package, each featuring input common-mode range extending to ground and rail-to-rail output swing-guaranteed to within 160 mV of either rail into 600 Ω. Its unity-gain stable architecture supports capacitive loads up to 10 nF when used with isolation resistors, per TI application note AN-397.

It operates across 2.5 V to 5.5 V supply, with guaranteed input offset voltage ≤3.5 mV, CMRR ≥70 dB, and PSRR ≥70 dB. The device maintains 5 MHz GBW and ≥61° phase margin under 2.7 V/2 kΩ load conditions, confirming suitability for precision AC-coupled sensor buffering and active filter stages.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.5 V to 5.5 V - supports single-cell Li-ion, dual-cell alkaline, and 3.3 V system rails without level-shifting.
Gain-Bandwidth Product	5 MHz - enables stable unity-gain buffer operation up to ~300 kHz with 10 kΩ load and <1% gain error.
Slew Rate (min)	1.4 V/µs - sufficient for 1 VPP signals at ≤220 kHz without slew-induced distortion.
Quiescent Current / Amp	220 µA at 2.7 V - draws only 880 µA total for all four amplifiers, critical for always-on sensor nodes.
Input Offset Voltage (max)	3.5 mV - ensures ≤0.7% full-scale error in 0.5 V reference-based comparators or 12-bit ADC front-ends.
Rail-to-Rail Output Swing	Within 160 mV of rails into 600 Ω - preserves dynamic range in low-voltage audio line drivers and transceiver I/O stages.

Pinout & Package

TSSOP-14 surface-mount package (4.4 mm × 5.0 mm × 1.2 mm), lead-free and RoHS-compliant, optimized for automated assembly and thermal performance (θ_JA = 155 °C/W).

Pin	Circuit Role	Design Meaning
1	Inverting Input (Amp A)	High-impedance node for feedback network connection; bias current ≤150 nA max ensures low offset in high-Z sensor interfaces.
2	Non-Inverting Input (Amp A)	Ground-referenced input capability enables single-supply DC-coupled transducer amplification without level shifters.
3	Output (Amp A)	Rail-to-rail output drives 600 Ω loads to within 160 mV of V+ or V−; stable with ≥100 pF capacitive loads when isolated.
4	V− (Ground)	Power return for all four amplifiers; requires low-impedance local decoupling (e.g., 0.1 µF X7R ceramic) near pin 4.
5	Non-Inverting Input (Amp B)	Independent input for second channel; shares no internal coupling with Amp A-crosstalk rejection >135 dB at 1 kHz.
6	Inverting Input (Amp B)	Configurable for inverting gain stages; input common-mode range includes ground, supporting true single-supply summing junctions.
7	Output (Amp B)	Electrically isolated output stage; capable of sourcing 12 mA or sinking 12 mA at 2.7 V while maintaining RRO swing.
8	V+	Positive supply rail for all amplifiers; accepts 2.5–5.5 V; must be bypassed locally to minimize PSRR degradation above 10 kHz.
9	Output (Amp C)	Third independent output; identical specs to Amp A/B; validated for use in dual-amplifier active filters (DAAFs) per TI AN-100128.
10	Inverting Input (Amp C)	Supports high-Q filter topologies; input capacitance <3 pF minimizes Q-sensitivity to stray board capacitance.
11	Non-Inverting Input (Amp C)	Enables DC-coupled instrumentation configurations; maximum input voltage = V− −0.3 V to V+ −0.2 V.
12	Output (Amp D)	Fourth output; tested for simultaneous operation-no thermal derating required at 85 °C ambient with 155 °C/W θ_JA.
13	Inverting Input (Amp D)	Validated in tri-level voltage detector circuits; input offset drift ≤1 µV/°C maintains threshold accuracy over temperature.
14	Non-Inverting Input (Amp D)	Used in telephone-line transceiver differential receivers; common-mode rejection ≥70 dB ensures noise immunity on twisted-pair lines.

Stable with heavy capacitive loads	Drives ≥10 nF via 20 Ω isolation resistor (per Figure 4, AN-100128), eliminating need for external compensation networks.
Low input offset drift	1 µV/°C max ensures <10 µV total drift over −40 °C to +85 °C-critical for precision DC measurement front-ends.
Amp-to-amp crosstalk rejection	135 dB at 1 kHz prevents inter-channel interference in multi-channel data acquisition and audio mixing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-voltage, rail-to-rail output op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2464IDR	Higher quiescent current (550 µA/amp), wider supply range (2.7–6 V), lower GBW (6.4 MHz), same TSSOP-14 package.	Better drive strength (20 mA) but higher power; less suitable for ultra-low-power always-on sensing.	Select TLV2464IDR when higher output current or extended supply range outweighs 2.5× higher IQ.
MCP6004-E/SL	Lower GBW (1 MHz), lower IQ (100 µA/amp), same rail-to-rail I/O, SOIC-14 package (larger footprint).	Cost-optimized for low-frequency (<100 kHz) sensor buffering where speed is secondary to power savings.	Choose MCP6004-E/SL for cost-sensitive, low-bandwidth applications where 5 MHz capability is unnecessary.

Compared with LMV824NDGVR, TLV2464IDR trades 2.5× higher supply current for stronger output drive and marginally higher bandwidth, while MCP6004-E/SL reduces power by half at the expense of 80% bandwidth loss-making LMV824NDGVR the optimal balance for portable 5 MHz signal chains.

FAQ

What is the maximum capacitive load the LMV824NDGVR can drive without oscillation?

The LMV824NDGVR is stable driving ≥10 nF when used with a 20 Ω isolation resistor in series with the output, as validated in TI Application Note AN-100128 Figure 4. Without isolation, stability is guaranteed for ≤100 pF. Driving larger capacitive loads directly risks phase margin collapse below 60°, leading to overshoot or ringing in pulse responses. Always verify layout parasitics-trace capacitance exceeding 5 pF may require re-evaluation of the isolation strategy for the LMV824NDGVR.

Does the LMV824NDGVR support true single-supply operation with input signals at ground potential?

Yes, the LMV824NDGVR supports true single-supply operation: its input common-mode voltage range extends to V− (ground) across the full temperature range, and its output swings rail-to-rail into 600 Ω loads. This allows direct interfacing with ground-referenced sources like thermistors or bridge sensors without external level-shifting circuitry-confirmed by guaranteed V_CM = −0.3 V min at 5 V supply and −0.2 V min at 2.7 V in the LMV824NDGVR datasheet.

What is the guaranteed slew rate for the LMV824NDGVR at 2.7 V supply?

The LMV824NDGVR guarantees a minimum slew rate of 1.4 V/µs at 2.7 V supply, measured under voltage-follower configuration with a 3 V step input (per datasheet Note 7). This value is tested across temperature and process corners-not just typical-and ensures predictable large-signal transient response in battery-powered audio and data acquisition paths where the LMV824NDGVR is deployed.

Can the LMV824NDGVR replace the LMV824M in existing SOIC-14 designs?

No-LMV824NDGVR uses a TSSOP-14 package (4.4 mm × 5.0 mm), while LMV824M uses SOIC-14 (3.9 mm × 8.7 mm). Footprint and thermal characteristics differ significantly: TSSOP has θ_JA = 155 °C/W vs. SOIC's 145 °C/W, and pad layout is incompatible. Direct replacement requires PCB redesign. For drop-in compatibility, use LMV824MT (TSSOP-14 variant with identical marking and specs) or LMV824MX (SOIC-14 tape-and-reel).

How does the LMV824NDGVR's input offset voltage drift affect precision DC measurements?

The LMV824NDGVR guarantees input offset voltage drift ≤1 µV/°C, meaning total drift over −40 °C to +85 °C is ≤125 µV. In a 12-bit system with 2.5 V reference, this contributes <0.2 LSB error-well within specification for most portable instrumentation. This low drift, combined with ≤3.5 mV initial V_OS, makes the LMV824NDGVR suitable for uncalibrated DC-coupled sensor front-ends where thermal compensation would otherwise add cost and complexity.
