Product details
Overview
LM2904LVIDR from Texas Instruments is a dual-channel, low-voltage operational amplifier designed for cost-sensitive, single-supply systems operating from 2.7 V to 5.5 V. It delivers ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, 40 nV/√Hz input voltage noise density, 90 µA per channel quiescent current, and rail-to-rail input common-mode range including ground - enabling precision signal conditioning in battery-powered environmental sensors and low-side current sensing circuits.
For engineers reviewing the LM2904LVIDR datasheet, LM2904LVIDR pinout, LM2904LVIDR application, or LM2904LVIDR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated package and pin functions, confirmed alternative options with functional distinctions, and supply-chain support details specific to the SOIC-8 (D) variant.
Technical Context
The LM2904LVIDR uses a P-channel input differential pair extended with a parallel N-channel pair to eliminate phase reversal during overdrive - a critical reliability feature absent in legacy LM2904 designs. Its internal ESD protection meets 2-kV HBM, and it operates across –40°C to 125°C without performance degradation in open-loop gain (110–125 dB), PSRR (80–100 dB), or CMRR (63–92 dB).
It is unity-gain stable with 75° phase margin at 5.5 V supply and supports capacitive loads up to 1000 pF while maintaining ≥50° phase margin. The device exhibits no phase reversal under overdrive conditions and recovers from saturation in 1 µs, enabling robust use in feedback loops with fast transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into Li-ion (3.0–4.2 V) and USB-powered (5 V) systems without LDO pre-regulation. |
| Input Offset Voltage | ±1 mV (typ), ±5 mV (max over temp) - ensures ≤0.5% error in 100-mV shunt-based current sensing at room temperature. |
| Unity-Gain Bandwidth | 1 MHz - supports closed-loop bandwidths up to ~700 kHz in gain-of-10 configurations for sensor amplification and filtering. |
| Quiescent Current | 90 µA per channel (typ) - allows two-channel operation on <180 µA total, suitable for always-on battery monitoring nodes. |
| Input Common-Mode Range | Extends to V− (ground) and within 1 V of V+ - permits true single-supply operation with inputs referenced to ground in low-side sensing. |
| Output Voltage Swing | Within 40 mV of V− and 1 V of V+ (at –40°C to 125°C, RL ≥ 10 kΩ) - delivers usable dynamic range in 3.3-V systems with 3.0-V output headroom. |
| ESD Rating | ±2000 V HBM - meets IEC 61000-4-2 Level 2 system-level ESD immunity requirements without external protection diodes. |
Pinout & Package
LM2904LVIDR is packaged in an industry-standard 8-pin SOIC (D) body measuring 3.91 mm × 4.90 mm, with thermal resistance RθJA = 207.9°C/W and RθJB = 129.7°C/W - compatible with standard reflow profiles and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives feedback networks or downstream ADC inputs; capable of sourcing/sinking ±40 mA short-circuit current. |
| 2 | IN1− | Inverting input, channel 1 - connects to feedback resistor in inverting configurations; accepts common-mode voltages down to ground. |
| 3 | IN1+ | Noninverting input, channel 1 - used for reference or sensor input in noninverting gain stages; input bias current ≤15 pA minimizes offset errors. |
| 4 | V− | Negative supply or ground - serves as return path for both amplifiers; must be low-impedance to maintain PSRR >80 dB. |
| 5 | IN2+ | Noninverting input, channel 2 - independent signal path for dual-sensor interfaces or differential pair buffering. |
| 6 | IN2− | Inverting input, channel 2 - supports matched gain-setting resistors for consistent channel-to-channel performance. |
| 7 | OUT2 | Amplifier 2 output - enables dual-path signal processing (e.g., sensor + reference buffer) without cross-talk. |
| 8 | V+ | Positive supply - accepts 2.7–5.5 V; requires local 0.1-µF ceramic bypass capacitor to suppress supply-induced noise. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal under overdrive | Eliminates output latch-up in transient-heavy applications like motor current sensing or power supply fault detection. |
| Rail-to-rail input common-mode range | Enables direct interface to ground-referenced sensors (e.g., thermistors, shunt resistors) without level-shifting circuitry. |
| 1 µs overload recovery time | Reduces settling delay after input step events, improving accuracy in fast-sampling data acquisition systems. |
| Low 40 nV/√Hz input voltage noise | Maintains SNR >70 dB in 10-kHz bandwidth sensor front-ends, critical for high-resolution environmental measurements. |
| Stable at unity gain with 1000-pF load | Permits direct driving of long PCB traces or ADC input capacitance without external compensation components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2904LVDR | Same silicon die and electrical specs; differs only in tape-and-reel packaging (DR vs D) - identical SOIC-8 footprint and pinout. | No functional difference; selected when automated pick-and-place requires 2500-unit reel instead of tube packaging. | Drop-in replacement for LM2904LVIDR in SMT production lines requiring reel delivery. |
| TLV2462IDR | Higher 6.4 MHz GBW, lower 22 nV/√Hz noise, but 230 µA/ch quiescent current and narrower 2.7–6 V supply range. | Better for bandwidth-critical sensor interfaces (e.g., ultrasonic flow meters), less suitable for ultra-low-power always-on monitoring. | Choose TLV2462IDR when >1 MHz closed-loop bandwidth or <25 nV/√Hz noise is required, accepting higher supply current. |
Compared with LM2904LVIDR, LM2904LVDR offers identical performance in reel format for volume SMT assembly, while TLV2462IDR trades 2.6× higher quiescent current for 6.4× greater bandwidth and 45% lower noise - making it optimal for speed- or SNR-critical, non-battery-constrained applications.

FAQ
What is the maximum supply voltage for LM2904LVIDR?
The absolute maximum supply voltage for LM2904LVIDR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Exceeding 6 V risks permanent damage per Absolute Maximum Ratings. At 5.5 V, the device achieves full specification compliance across –40°C to 125°C, including PSRR ≥80 dB and CMRR ≥63 dB.
Does LM2904LVIDR support rail-to-rail input?
Yes, LM2904LVIDR supports rail-to-rail input common-mode voltage range extending to V− (ground) and within 1 V of V+. This is achieved via a P-channel input stage with auxiliary N-channel pair, enabling true single-supply operation in low-side current sensing and ground-referenced sensor interfaces without external level shifters.
What is the typical quiescent current per channel for LM2904LVIDR?
The typical quiescent current per channel for LM2904LVIDR is 90 µA at 5.5 V supply and 25°C. Over temperature (–40°C to 125°C), it rises to 160 µA max. This ultra-low current enables dual-channel operation below 180 µA total - ideal for battery-backed monitoring nodes where standby power must remain under 200 µA.
Is LM2904LVIDR unity-gain stable?
Yes, LM2904LVIDR is unity-gain stable with ≥75° phase margin at 5.5 V supply and remains stable driving up to 1000 pF capacitive load. Its internal compensation eliminates need for external compensation networks, simplifying design in gain-of-1 configurations such as voltage followers and active filters.
What package type is LM2904LVIDR supplied in?
LM2904LVIDR is supplied in an 8-pin SOIC (D) package with body dimensions 3.91 mm × 4.90 mm. This industry-standard package supports automated assembly, has RθJA = 207.9°C/W, and is pin-compatible with other LM2904LV variants in SOIC-8, TSSOP-8, VSSOP-8, and SOT-23-8 packages.
