Product details
Overview
LM2902LVIPWR 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.
For engineers reviewing the LM2902LVIPWR datasheet, LM2902LVIPWR pinout, LM2902LVIPWR application, or LM2902LVIPWR equivalent, this page provides verified package mapping (TSSOP-14), confirmed pin functions, real-world use cases in HVAC transmitters and UPS monitoring, and two validated alternative op amps with documented functional and thermal differences.
Technical Context
The LM2902LVIPWR uses a P-channel input stage with parallel N-channel pair to extend common-mode range to the negative rail while eliminating phase reversal during overdrive - critical for reliable operation in unregulated supply rails. Its unity-gain stability and 1.5 V/µs slew rate support fast settling (4 µs to 0.1%) without external compensation.
Designed for industrial temperature range (–40°C to 125°C), it maintains 84 dB CMRR and 80 dB PSRR across full supply range, with robust 2-kV HBM ESD rating and internal diode-clamped inputs that tolerate ±0.5 V beyond rails when current-limited to 10 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables multi-sensor signal chains or multi-stage filtering in one package |
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct Li-ion (3.0–4.2 V) and USB-powered (5 V) systems without LDO |
| Input Offset Voltage | ±1 mV (typ) - ensures ≤10 mV error at 10× gain in low-side current sensing with 100 mΩ shunt |
| Unity-Gain Bandwidth | 1 MHz - sufficient for DC–100 kHz sensor amplification and anti-aliasing filter design |
| Quiescent Current | 90 µA per channel - allows four independent amplifiers to operate below 360 µA total, ideal for always-on sensor nodes |
| Input Voltage Noise | 40 nV/√Hz at 1 kHz - preserves SNR in millivolt-level thermistor or bridge sensor outputs |
| Common-Mode Range | Extends to V– (ground) - enables true single-supply operation with rail-to-rail input in 0–3.3 V systems |
Pinout & Package
TSSOP-14 package (4.40 mm × 5.00 mm body size) with exposed pad for thermal enhancement; JEDEC-standard footprint compatible with automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output (OUT1–OUT4) | Amplifier output stages capable of sourcing/sinking ±40 mA; swing within 40 mV of V– and 1 V of V+ at full temperature range |
| 2, 6, 9, 13 | Inverting Input (IN1––IN4–) | Differential input pins with 2 pF differential capacitance; require matched trace lengths in high-frequency layouts |
| 3, 5, 10, 12 | Noninverting Input (IN1+–IN4+) | High-impedance (±15 pA bias current) inputs compatible with high-value sensor resistors up to 1 MΩ |
| 4 | Positive Supply (V+) | Main power rail connection; requires local 0.1 µF ceramic bypass capacitor to minimize supply-induced noise coupling |
| 11 | Negative Supply / Ground (V–) | Reference node for single-supply operation; must be low-impedance ground plane connection to maintain CMRR |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal under overdrive | Guaranteed via dual-input-stage architecture - prevents latch-up or erroneous output during transient input excursions beyond rails |
| EMI rejection ratio >60 dB | Validated from 10 MHz to 1 GHz - suppresses RF interference from switching regulators and wireless modules in dense PCB layouts |
| Channel separation >100 dB | Measured at 1 kHz - minimizes crosstalk between adjacent amplifiers in multi-channel data acquisition |
| Low 1/f noise corner | 5.1 µVPP integrated (0.1–10 Hz) - critical for stable DC offset in temperature transmitter front-ends |
| Thermal resistance (RθJA) | 148.3 °C/W (TSSOP-14) - enables continuous operation at 125°C ambient with <100 mW total dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage, quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher 6.4 MHz GBW but 250 µA/ch IQ; no guaranteed phase-reversal immunity | Better for AC-coupled audio or higher-speed filtering; less suitable for DC-critical current sensing | Select when bandwidth >1 MHz is required and power budget allows 2.8× higher IQ |
| LM324BIPWR | Wider 3–36 V supply range but 250 µA/ch IQ; only 70°C max operating temp | Compatible with legacy 12 V/24 V industrial systems; not rated for automotive or extended-temp deployments | Select for backward compatibility in existing 12 V designs where extended temperature is not required |
Compared with TLV2464IDR and LM324BIPWR, the LM2902LVIPWR uniquely balances ultra-low power (90 µA/ch), guaranteed rail-to-rail input operation down to ground, and phase-reversal immunity - making it optimal for new battery-powered and extended-temperature sensor nodes where power and DC accuracy are primary constraints.

FAQ
What is the maximum operating temperature for LM2902LVIPWR?
The LM2902LVIPWR is specified for continuous operation from –40°C to +125°C ambient temperature. Its thermal resistance (RθJA = 148.3 °C/W in TSSOP-14) ensures junction temperature remains within safe limits (<150°C) under typical load conditions at 125°C ambient, making it suitable for enclosed industrial environments and automotive under-hood proximity applications.
Does LM2902LVIPWR support true single-supply operation with input signals at ground?
Yes. The LM2902LVIPWR features a P-channel input stage that extends the common-mode input voltage range to the negative supply rail (V–), which is typically grounded in single-supply configurations. This allows direct amplification of 0 V referenced sensor signals - such as thermistor dividers or shunt voltages - without level-shifting circuitry, as confirmed in Section 7.3.2 of the SBOS960C datasheet.
What is the overload recovery time of LM2902LVIPWR and why does it matter?
The LM2902LVIPWR has a typical overload recovery time of 1 µs, defined as the time required for the output to return from saturation to linear operation after an overdriven input condition. This fast recovery prevents signal distortion in pulse-width modulated systems or transient-heavy environments like motor drive current sensing, where rapid return to accurate amplification is essential for closed-loop stability.
Can LM2902LVIPWR replace LM2902 in existing designs?
The LM2902LVIPWR is not a direct drop-in replacement for standard LM2902 due to its lower supply voltage range (2.7–5.5 V vs. 3–32 V) and optimized low-voltage performance. However, it is pin-compatible with LM2902 in TSSOP-14 and offers superior offset (±1 mV vs. ±3 mV), lower IQ (90 µA vs. 1.2 mA), and guaranteed phase-reversal immunity - making it ideal for redesigning legacy 5 V systems toward lower power and higher accuracy.
What package options are available for LM2902LVIPWR besides TSSOP-14?
The LM2902LVIPWR is specifically the TSSOP-14 variant (orderable part number suffix 'PWR'). Other LM2902LV variants include SOIC-14 ('D') and SOT-23-14 ('DYY'), but LM2902LVIPWR refers exclusively to the 4.40 mm × 5.00 mm TSSOP package with thermal pad - verified in TI's SBOS960C datasheet Device Information table and Pin Configuration section.
