Product details
Overview
LM2902LVIDYYR from Texas Instruments is a quad-channel, low-voltage operational amplifier designed for cost-sensitive, single-supply signal conditioning in battery-powered and industrial systems. It delivers ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, 90 µA per channel quiescent current, and rail-to-rail input common-mode range extending to ground - enabling precision low-side current sensing and sensor amplification at 2.7 V to 5.5 V supply.
For engineers reviewing the LM2902LVIDYYR datasheet, LM2902LVIDYYR pinout, LM2902LVIDYYR application, or LM2902LVIDYYR equivalent, this page provides verified specifications, SOT-23-14 package details, functional role in low-voltage analog front-ends, and validated alternative options for design continuity and sourcing resilience.
Technical Context
The LM2902LVIDYYR implements a P-channel input stage with parallel N-channel pair to eliminate phase reversal during overdrive, supporting robust operation in single-supply configurations where inputs swing to ground. Its unity-gain stability and 75° phase margin ensure reliable performance in closed-loop gain ≥1 circuits without external compensation.
It features internal ESD protection rated at ±2 kV HBM and operates across –40°C to 125°C, with input voltage noise density of 40 nV/√Hz at 1 kHz and 5.1 µVPP (0.1–10 Hz), making it suitable for low-frequency sensor interfaces requiring low power and DC accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - supports four independent amplification paths in one SOT-23-14 package, reducing board space vs discrete duals. |
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration with Li-ion, 3.3 V, and 5 V logic rails without level-shifting. |
| Input Offset Voltage | ±1 mV (typ) - ensures ≤10 mV error in 10 V full-scale output applications without trimming. |
| Unity-Gain Bandwidth | 1 MHz - supports stable amplification of signals up to ~100 kHz with <1% gain error. |
| Quiescent Current / Ch | 90 µA (typ) - allows >1-year battery life in always-on sensor nodes powered by CR2032 cells. |

| ESD Rating (HBM) | ±2 kV - meets IEC 61000-4-2 Level 2 for system-level robustness in consumer and industrial environments. |
Pinout & Package
SOT-23-14 (DYY) package: 4.20 mm × 2.00 mm body, 0.65 mm pitch, thin-profile surface-mount construction optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads ≥2 kΩ; swings within 40 mV of V– and 1 V of V+ at full temperature range. |
| 2 | IN1– | Inverting input, channel 1 - accepts differential signals referenced to ground; input bias current ≤15 pA minimizes resistor-induced errors. |
| 3 | IN1+ | Noninverting input, channel 1 - used for reference or sensor input; common-mode range includes V– for true single-supply operation. |
| 4 | V+ | Positive supply - must be bypassed with 0.1 µF capacitor near pin to suppress supply noise coupling into analog signal path. |
| 5 | IN2+ | Noninverting input, channel 2 - electrically isolated from channel 1; channel separation >–100 dB at 1 kHz prevents crosstalk in multi-sensor systems. |
| 6 | IN2– | Inverting input, channel 2 - supports differential configurations; matched input capacitance (2 pF diff, 5.5 pF cm) ensures balanced AC response. |
| 7 | OUT2 | Amplifier 2 output - identical drive capability to OUT1; slew rate 1.5 V/µs enables fast settling for step inputs. |
| 8 | OUT3 | Amplifier 3 output - shares same thermal and electrical characteristics as OUT1/OUT2; supports triple-redundant or multi-path signal processing. |
| 9 | IN3– | Inverting input, channel 3 - enables third independent gain stage; input offset drift ±4 µV/°C maintains accuracy across wide ambient ranges. |
| 10 | IN3+ | Noninverting input, channel 3 - compatible with low-impedance sources; CMRR ≥84 dB (2.7 V) rejects supply ripple in noisy environments. |
| 11 | V– | Negative supply / ground - serves as return path for all channels; must be low-impedance to prevent ground bounce in multi-channel switching. |
| 12 | IN4+ | Noninverting input, channel 4 - supports fourth sensor interface; PSRR ≥80 dB suppresses supply noise from affecting DC-coupled measurements. |
| 13 | IN4– | Inverting input, channel 4 - matches IN1–/IN2–/IN3– electrical specs; enables precision difference amplification with external resistors. |
| 14 | OUT4 | Amplifier 4 output - completes quad functionality; overload recovery time 1 µs ensures rapid return from saturation in transient-heavy applications. |

| Low 40 nV/√Hz input noise | Preserves SNR in microvolt-level sensor outputs (e.g., RTDs, strain gauges) without requiring external filtering. |
| 1.5 V/µs slew rate | Supports 100 kHz small-signal amplification with <1% distortion; sufficient for motor control feedback loops. |
| –40°C to 125°C operating range | Validated for under-hood automotive, industrial PLC, and outdoor environmental sensor deployments. |
| 154.6 °C/W RθJA (SOT-23-14) | Thermal resistance enables 100 mW dissipation at TA = 85°C without derating - suitable for compact enclosures. |

FAQ
What is the maximum operating temperature for LM2902LVIDYYR?
The LM2902LVIDYYR is fully specified from –40°C to +125°C ambient temperature, with junction temperature rated up to 150°C. Its SOT-23-14 package exhibits 154.6 °C/W junction-to-ambient thermal resistance, allowing safe operation at full rating in typical industrial enclosures with moderate airflow. Derating is not required below 125°C ambient.
Does LM2902LVIDYYR support single-supply operation?
Yes, LM2902LVIDYYR supports true single-supply operation: its input common-mode voltage range extends to the negative rail (V–, typically ground), and output swings within 40 mV of V– and 1 V of V+ across temperature. This enables direct interfacing with ground-referenced sensors and shunt resistors without dual supplies or level shifters.
What is the input offset voltage specification for LM2902LVIDYYR?
The LM2902LVIDYYR has a maximum input offset voltage of ±3 mV at 25°C and ±5 mV over the full –40°C to +125°C temperature range. The typical value is ±1 mV at 25°C, with offset drift of ±4 µV/°C - enabling accurate DC-coupled amplification in precision sensor front-ends without calibration.
Can LM2902LVIDYYR drive capacitive loads?
LM2902LVIDYYR is unity-gain stable and tested for capacitive loads up to 1000 pF, with phase margin maintained above 70°. For loads >100 pF, TI recommends adding a small series resistor (10–50 Ω) between output and capacitance to isolate the op amp's output impedance from the reactive load and prevent peaking or oscillation.
Is LM2902LVIDYYR pin-compatible with other LM2902 variants?
LM2902LVIDYYR shares identical pinout with all LM2902LV variants in 14-pin packages (SOIC, TSSOP, SOT-23), including LM2902LVDR and LM2902LVTPWR. However, it is not pin-compatible with legacy LM2902 (non-LV) due to differences in input stage architecture and ESD structure - verify schematic symbol and footprint before substitution.
