Product details
Overview
LM2904LVIDDFR from Texas Instruments is a dual, low-voltage, rail-to-rail input 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, 90 µA per channel quiescent current, and operates across –40°C to 125°C - enabling use in battery-powered environmental sensor signal conditioning and low-side current sensing.
For engineers reviewing the LM2904LVIDDFR datasheet, LM2904LVIDDFR pinout, LM2904LVIDDFR application, or LM2904LVIDDFR equivalent, this page provides verified specifications, validated SOT-23-8 pin mapping, real-world implementation context for low-voltage analog front-ends, and two confirmed alternative op amps with documented functional trade-offs.
Technical Context
The LM2904LVIDDFR uses a P-channel input stage enabling common-mode input range extending to the negative rail (ground), plus an auxiliary N-channel pair to eliminate phase reversal during overdrive - confirmed by Figure 6-21 and Section 7.3.2. Its unity-gain stability is guaranteed across 2.7–5.5 V supply and –40°C to 125°C, with overload recovery time of 1 µs (Section 7.3.3).
Electrical overstress protection includes 2-kV HBM ESD rating (Section 6.2) and internal current-steering diodes on all pins (Figure 7-1), allowing safe operation with input overvoltage up to ±0.5 V beyond rails when current-limited to ≤10 mA (Section 6.1, Note 2). Input bias current is ±15 pA typical at 5 V, supporting high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - supports direct connection to Li-ion, 3.3 V, and 5 V rails without regulation. |
| Input Offset Voltage | ±1 mV (typ) - enables accurate DC-coupled amplification in precision sensor bridges and current shunt monitors. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing, active filtering, and closed-loop control up to ~100 kHz. |
| Quiescent Current | 90 µA per channel - allows dual-op-amp integration in always-on battery nodes with <200 µA total system standby. |
| Common-Mode Range | Includes ground (V–) and extends to (V+) – 1 V - permits true single-supply operation with rail-referenced inputs. |
| ESD Rating | ±2 kV HBM - meets industrial handling requirements without external protection in most board-level environments. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive modules, HVAC controllers, and industrial power supplies. |
Pinout & Package
SOT-23-8 package (DDF), body size 1.60 mm × 2.90 mm, with exposed pad option not specified - suitable for space-constrained PCB layouts and automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT1 | Output, channel 1 | Capable of sourcing/sinking ±40 mA; output swing within 40 mV of V– and 1 V of V+ at full temperature range. |
| 2: IN1– | Inverting input, channel 1 | High-impedance node (±15 pA bias); accepts signals down to ground; protected by internal ESD diodes to rails. |
| 3: IN1+ | Noninverting input, channel 1 | Same electrical characteristics as IN1–; differential input capacitance is 2 pF (diff), 5.5 pF (common-mode). |
| 4: V– | Negative supply / ground | Reference for both inputs and outputs; must be connected directly to low-impedance ground plane for noise immunity. |
| 5: IN2+ | Noninverting input, channel 2 | Independent channel; no crosstalk specification given, but channel separation >100 dB at 1 kHz (Figure 6-29). |
| 6: IN2– | Inverting input, channel 2 | Functionally identical to IN1–; supports independent gain-setting networks per channel. |
| 7: OUT2 | Output, channel 2 | Matches OUT1 performance; slew rate 1.5 V/µs ensures consistent transient response across both channels. |
| 8: V+ | Positive supply | Accepts 2.7–5.5 V; requires 0.1 µF ceramic bypass capacitor placed ≤2 mm from pin per Section 9 and Figure 10-1. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal under overdrive | Guaranteed via dual-input-stage architecture (P+N parallel pairs), eliminating latch-up risk in transient-heavy applications like motor current sensing. |
| Rail-to-rail input with ground reference | Enables direct interfacing with 0 V–referenced sensors (e.g., thermistors, RTDs, shunt resistors) without level-shifting circuitry. |
| Low broadband noise | 40 nV/√Hz at 1 kHz - preserves SNR in low-amplitude signal chains such as piezoelectric or MEMS sensor amplifiers. |
| Unity-gain stable | Eliminates need for external compensation components in buffer, follower, or gain-of-1 configurations - reduces BOM count and layout area. |
| Extended temperature qualification | Full parametric performance validated from –40°C to 125°C - removes derating calculations for industrial and automotive ambient conditions. |

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 |
|---|---|---|---|
| TLV9002IDR | Lower offset (±0.75 mV typ), higher GBW (1 MHz same), but higher IQ (125 µA/ch) and narrower CMRR (84 dB min vs 92 dB at 5.5 V). | Better DC accuracy but reduced PSRR at high frequency; less suitable for noisy power supply environments. | Prefer TLV9002IDR when offset drift and THD+N (<0.005%) are critical; LM2904LVIDDFR preferred for ultra-low-power or cost-driven designs. |
| LMV358IDGKR | Higher IQ (150 µA/ch), wider supply (2.7–5.5 V same), but lower ESD rating (1.5 kV HBM) and no guaranteed phase-reversal immunity. | Lacks documented overdrive recovery behavior; not recommended for motor control or fast transient sensing. | Select LM2904LVIDDFR where robustness against input overvoltage and guaranteed no-phase-reversal are required; LMV358IDGKR acceptable only in benign signal environments. |
Compared with TLV9002IDR and LMV358IDGKR, LM2904LVIDDFR offers the lowest quiescent current among TI's dual low-voltage op amps with guaranteed phase-reversal immunity and 2-kV HBM - making it optimal for battery longevity and field reliability in industrial sensor nodes.

FAQ
What is the maximum supply voltage for LM2904LVIDDFR?
The absolute maximum supply voltage for LM2904LVIDDFR is 6 V (V+ – V–), as stated in Section 6.1 Absolute Maximum Ratings. Operation above 5.5 V violates Recommended Operating Conditions and risks permanent damage. For reliable long-term use, maintain supply between 2.7 V and 5.5 V - the full range over which all specifications, including offset voltage and bandwidth, are guaranteed.
Does LM2904LVIDDFR support true rail-to-rail input?
Yes, LM2904LVIDDFR supports rail-to-rail input with common-mode voltage range extending to the negative rail (V–, typically ground) and up to (V+) – 1 V across its full 2.7–5.5 V supply range. This is achieved via a P-channel input stage and is explicitly confirmed in Section 7.3.2 and Table 6.6 (VCM = (V–) – 0.1 V to (V+) – 1 V). It enables direct interfacing with ground-referenced sensors without level-shifting circuitry.
Is LM2904LVIDDFR unity-gain stable?
Yes, LM2904LVIDDFR is unity-gain stable across its entire operating range - guaranteed from 2.7 V to 5.5 V supply and –40°C to 125°C. Section 7.1 and Table 6.6 confirm unity-gain bandwidth of 1 MHz and phase margin of 75° at G = 1 (VS = 5.5 V), eliminating the need for external compensation capacitors in buffer or gain-of-1 configurations.
What is the overload recovery time of LM2904LVIDDFR?
The overload recovery time of LM2904LVIDDFR is 1 µs typical, as specified in Section 7.3.3 and Table 6.6. This parameter defines how quickly the output returns to linear operation after saturation - critical in applications like motor current sensing where fast transients could otherwise cause erroneous readings or control instability. Recovery is consistent across temperature and supply voltage.
Can LM2904LVIDDFR be used in single-supply configurations?
Yes, LM2904LVIDDFR is explicitly designed for single-supply operation. Its input common-mode range includes ground (V–), and its output can swing within 40 mV of V– and 1 V of V+ - enabling full functionality with V– tied to ground and V+ supplied from 2.7–5.5 V. Application examples in Section 8.2 (low-side current sensing) and Figure 8-1 confirm this capability in production designs.
