Product details
Overview
LP2902PWRE4 from Texas Instruments is an ultra-low-power quadruple operational amplifier optimized for battery-powered systems. It delivers 85 μA typical supply current, 2 mV typical input offset voltage, and rail-to-rail output swing capability with single-supply operation down to 3 V - enabling precision signal conditioning in portable instrumentation and LCD display biasing circuits.
For engineers reviewing the LP2902PWRE4 datasheet, LP2902PWRE4 pinout, LP2902PWRE4 application, or LP2902PWRE4 equivalent, key selection criteria include its −40°C to +85°C operating temperature range, TSSOP-14 package footprint, ground-sensing input common-mode range, and compatibility with LM324-based designs requiring extended supply voltage (up to 32 V) and ultra-low quiescent current.
Technical Context
The LP2902PWRE4 implements four independent high-impedance voltage amplifiers in a single monolithic IC, each featuring input bias current as low as 2 nA and input common-mode voltage range extending to ground - critical for sensor front-end interfacing in single-supply configurations. Its architecture prioritizes power efficiency over bandwidth, with 100 kHz gain-bandwidth product and 50 V/ms slew rate.
It supports dual- or single-supply operation (3 V to 32 V), includes internal ESD protection rated at ±350 V HBM, and maintains stable DC performance across its full industrial temperature range without external compensation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 85 μA typical per amplifier - enables multi-year battery life in always-on sensor nodes and handheld meters. |
| Input offset voltage | 2 mV typical - ensures <1% error in 12-bit ADC front-ends with gain ≤10. |
| Input bias current | 2 nA typical - minimizes voltage drop across high-impedance sources like thermistors or photodiodes. |
| Supply voltage range | 3 V to 32 V single supply - supports direct integration into 5 V, 12 V, and 24 V industrial rails without level-shifting. |
| Output swing | Within 1.9 V of rails at full load - provides usable dynamic range in 5 V systems with 3.1 V headroom. |
| Gain-bandwidth product | 100 kHz - sufficient for DC-coupled transducer amplification, filter stages, and slow-settling control loops. |
| Common-mode range | Includes ground (0 V) - allows direct connection of unipolar sensors (e.g., RTDs, strain gauges) without bias resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM324DR | Higher 1.5 mA supply current; wider 0°C to 70°C temp range; same SOIC-14 pinout. | Not rated for −40°C operation; unsuitable for outdoor or automotive environments. | Select when cost sensitivity outweighs power budget and extended temperature requirements. |
| TLV2464IPW | Lower 600 μA supply current; rail-to-rail I/O; 2.5 V min supply; 2.2 MHz GBW. | Requires ≥2.5 V supply; higher bandwidth increases noise susceptibility in DC-coupled sensor paths. | Prefer when rail-to-rail input/output and faster settling are needed, and supply voltage ≥3.3 V is guaranteed. |
Compared with LM324DR and TLV2464IPW, the LP2902PWRE4 uniquely balances ultra-low power (85 μA), industrial temperature support (−40°C to +85°C), and ground-sensing inputs - making it optimal for long-life, wide-voltage, single-supply sensor interfaces where speed is secondary to precision and efficiency.

FAQ
What is the maximum operating temperature for the LP2902PWRE4?
The LP2902PWRE4 is specified for continuous operation from −40°C to +85°C ambient temperature. This industrial-grade rating is validated per TI's Recommended Operating Conditions and supported by thermal metrics including RθJA = 154°C/W for the TSSOP-14 (PW) package. The device maintains all electrical specifications across this full range, making LP2902PWRE4 suitable for deployment in automotive cabin modules, outdoor utility meters, and factory automation equipment.
Does the LP2902PWRE4 support true rail-to-rail input operation?
The LP2902PWRE4 supports input common-mode voltage range that includes ground (0 V) but does not extend to the positive rail (VCC). Its inputs operate from 0 V up to VCC − 1.5 V, as confirmed in the Electrical Characteristics table under Common-Mode Rejection Ratio test conditions. Output swing is rail-to-rail within 1.9 V of both rails under load. Therefore, LP2902PWRE4 is ground-sensing but not rail-to-rail input - a key distinction for biasing unipolar sensors while retaining DC accuracy.
Can the LP2902PWRE4 replace LM324 in existing designs without layout changes?
Yes - the LP2902PWRE4 is pin-compatible with LM324 in the TSSOP-14 (PW) package, sharing identical pin numbering, function mapping, and footprint dimensions. However, note that LP2902PWRE4 has different thermal and ESD characteristics (±350 V HBM vs. ±2 kV for older LM324 variants), and its lower supply current reduces power dissipation by >94%. No PCB modifications are required, but decoupling capacitor placement should follow TI's recommended layout for TSSOP packages to ensure stability.
What is the typical input offset voltage drift of the LP2902PWRE4 over temperature?
The LP2902PWRE4 exhibits a typical input offset voltage drift of 10 μV/°C, as specified in the Electrical Characteristics table under dVIO/dT. This value applies across the full −40°C to +85°C operating range and is measured with VCC = 5 V. This low drift ensures minimal calibration drift in precision measurement systems - for example, a 125°C span introduces only 1.25 mV additional offset, well within the 4 mV maximum VIO spec at temperature extremes. This performance is consistent across all LP2902 variants.
Is the LP2902PWRE4 RoHS compliant and lead-free?
The LP2902PWRE4 is RoHS compliant and features a lead-free terminal finish. According to TI's Packaging Information, the part uses "NIPDAU | SN" (nickel-palladium-gold over tin-lead-free solderable finish) and carries Level-1 moisture sensitivity rating with unlimited floor life at ≤30°C/60% RH. While the "E4" suffix historically indicated lead-free finish in TI's nomenclature, current documentation confirms LP2902PWRE4 meets JEDEC J-STD-020 and EU RoHS Directive 2011/65/EU requirements without exemptions.
