Product details
Overview
LM2902LVIDR from Texas Instruments is a quad-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, and 90 µA per-channel quiescent current - enabling precision signal conditioning in battery-powered environmental sensors and low-side current sensing circuits.
For engineers reviewing the LM2902LVIDR datasheet, LM2902LVIDR pinout, LM2902LVIDR application, or LM2902LVIDR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated package and pin mapping for SOIC-14, confirmed alternatives with functional and application-level differences, and supply-chain support tailored for industrial embedded and connected-device programs.
Technical Context
The LM2902LVIDR 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 LM2902 devices. Its rail-to-rail input common-mode range includes ground and extends to within 1 V of V+, supporting true single-supply operation without level-shifting.
It achieves unity-gain stability with no external compensation while maintaining 75° phase margin at 5.5 V supply and driving up to 100 pF capacitive load. The internal ESD protection meets 2-kV HBM (ANSI/ESDA/JEDEC JS-001) and incorporates steering diodes to V+ and V– rails, enabling robust in-circuit overvoltage tolerance when input current is limited to ≤10 mA.
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), USB-powered (5 V), and wide-input industrial rails without LDO pre-regulation. |
| Input Offset Voltage | ±1 mV (typ) - supports accurate DC-coupled amplification in sensor front-ends where <10 mV error is required (e.g., thermistor or RTD signal chains). |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing filtering, active low-pass stages up to ~100 kHz, and closed-loop gain ≥10 with stable response. |
| Quiescent Current | 90 µA per channel - allows four independent amplifiers to operate continuously on microampere-scale power budgets (e.g., battery-operated HVAC transmitters). |
| Input Voltage Noise | 40 nV/√Hz at 1 kHz - suitable for medium-bandwidth analog signal conditioning where sub-100 nV/√Hz noise floor is acceptable (e.g., pressure or humidity sensor buffers). |
| Common-Mode Range | Includes V– (ground) and extends to (V+) – 1 V - eliminates need for negative supply or input biasing in single-ended sensor interfaces like shunt-based current monitoring. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive modules, industrial motor drives, and outdoor environmental monitoring equipment. |
Pinout & Package
LM2902LVIDR is packaged in a 14-pin SOIC (D) with body size 8.65 mm × 3.91 mm, rated for surface-mount reflow assembly and compatible with standard IPC-7351B footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output (OUT1–OUT4) | Amplifier output terminals - each drives ≥2 kΩ load to within 1 V of V+ and 40 mV of V– at full temperature range. |
| 2, 6, 9, 13 | Inverting Input (IN1––IN4–) | Differential input nodes - accept signals down to V– (ground); internal P-channel pair ensures no phase reversal during overdrive. |
| 3, 5, 10, 12 | Noninverting Input (IN1+–IN4+) | Differential input nodes - same rail-to-rail common-mode capability as inverting inputs; matched offset and bias performance. |
| 4 | Positive Supply (V+) | Main power rail - accepts 2.7–5.5 V; requires local 0.1 µF ceramic bypass capacitor to minimize PSRR degradation above 10 kHz. |
| 11 | Negative Supply / Ground (V–) | Reference node for single-supply operation - tied directly to system ground; supports true ground-referenced input and output swing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input including ground | Enables direct interfacing with grounded sensors (e.g., thermocouples, shunt resistors) without external level shifters or dual supplies. |
| No phase reversal under overdrive | Guarantees predictable output behavior during transient overload - critical for closed-loop control feedback paths and comparator-like applications. |
| 2-kV HBM ESD rating | Meets IEC 61000-4-2 Level 2 for system-level ESD immunity - reduces need for external TVS diodes in board-level protection schemes. |
| Low 90 µA/channel quiescent current | Supports always-on signal conditioning in energy-harvesting or coin-cell-powered devices where total system IQ must stay below 500 µA. |
| Unity-gain stable with 100 pF load | Eliminates need for external compensation components in buffer, gain-of-1, or low-gain configurations - simplifies layout and BOM. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902DR | Higher offset (±3 mV typ), higher IQ (150 µA/ch), no guaranteed phase-reversal immunity, rated only to 105°C. | Suitable for cost-driven consumer appliances but not for automotive or industrial environments requiring full –40°C to 125°C operation or precise DC accuracy. | Select LM2902DR only if budget constraints outweigh need for extended temperature range and tighter offset spec. |
| TLV2464IDR | Lower noise (22 nV/√Hz), rail-to-rail output, higher IQ (550 µA/ch), narrower supply (2.7–6 V), 2.2 MHz GBW. | Better for high-fidelity audio buffering or fast-settling data acquisition, but excessive power draw disqualifies it for battery-backed sensor nodes. | Choose TLV2464IDR when speed/noise matter more than power; avoid in always-on IoT edge nodes where 90 µA/ch is mandatory. |
Compared with LM2902DR and TLV2464IDR, LM2902LVIDR uniquely balances ultra-low quiescent current, guaranteed phase-reversal immunity, and full industrial temperature range - making it the optimal choice for long-life, single-supply, cost-sensitive embedded systems where reliability and power efficiency are co-prioritized.

FAQ
What is the maximum capacitive load the LM2902LVIDR can drive while remaining stable?
The LM2902LVIDR is unity-gain stable with up to 100 pF capacitive load, as confirmed by phase margin measurements showing ≥75° at 5.5 V supply. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability. This capability makes LM2902LVIDR suitable for driving ADC input filters and long PCB traces without oscillation risk.
Does the LM2902LVIDR support true single-supply operation with inputs at ground potential?
Yes - the LM2902LVIDR's input common-mode voltage range explicitly includes V– (ground) and extends to (V+) – 1 V across its full 2.7–5.5 V supply range. This is enabled by its P-channel input stage and verified in electrical characteristics tables (VCM = (V–) – 0.1 V). It reliably amplifies grounded sensor signals without level-shifting circuitry.
How does the LM2902LVIDR differ from the standard LM2902 in overload recovery behavior?
The LM2902LVIDR guarantees no phase reversal during overdrive - a documented limitation of classic LM2902 devices. Its overload recovery time is specified at 1 µs (typ), and the internal complementary input stage ensures monotonic output recovery even when inputs exceed the common-mode range. This eliminates unpredictable latch-up in feedback loops during transients.
Is the LM2902LVIDR pin-compatible with the LM2902DR in SOIC-14 packages?
Yes - LM2902LVIDR and LM2902DR share identical SOIC-14 pinout, terminal functions, and footprint. However, LM2902LVIDR offers superior specifications: ±1 mV vs ±3 mV offset, 90 µA vs 150 µA/ch IQ, and guaranteed –40°C to +125°C operation versus LM2902DR's 105°C limit. Drop-in replacement is electrically valid where enhanced performance is beneficial.
What thermal derating applies to the LM2902LVIDR in SOIC-14 at 125°C ambient?
In SOIC-14 (D package), LM2902LVIDR has RθJA = 102.1°C/W. At 125°C ambient and 5.5 V supply, total power dissipation must remain below 300 mW to keep junction temperature ≤150°C. With 4 channels at 90 µA each, static power is only 2 mW - leaving ample headroom for output loading. No derating is needed for typical signal-conditioning use cases.
