Product details
Overview
LM2904ITP/NOPB from Texas Instruments is a dual, low-power, internally frequency-compensated operational amplifier optimized for single-supply operation from 3 V to 26 V. It delivers 100 dB DC voltage gain, 1 MHz unity-gain bandwidth (temperature compensated), 2 mV input offset voltage, and rail-to-ground output swing-enabling precision signal conditioning in battery-powered industrial sensors and 4–20 mA current loop transmitters.
For engineers reviewing the LM2904ITP/NOPB datasheet, LM2904ITP/NOPB pinout, LM2904ITP/NOPB application, or LM2904ITP/NOPB equivalent, key selection criteria include its ground-sensing input common-mode range, ultra-low 500 µA supply current per amplifier, DSBGA-8 package footprint (1.31 mm × 1.31 mm), and guaranteed operation from −40°C to +85°C.
Technical Context
The LM2904ITP/NOPB implements a PNP-input stage enabling input common-mode voltage down to ground and differential input voltage up to the full supply rail-without external clamping diodes. Its class-A/class-B hybrid output stage supports both sourcing and sinking while maintaining low quiescent current across 3 V–26 V supply range.
Temperature compensation applies to unity-gain crossover frequency, input bias current, and input offset voltage drift (7 µV/°C typical). The device operates linearly with inputs at 0 V and outputs capable of swinging to within 20 mV of ground under 10 kΩ load-critical for single-supply sensor front-ends and analog I/O interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 26 V single supply (±1.5 V to ±13 V dual); enables direct interface with 3.3 V/5 V logic and eliminates need for negative rails |
| Input Offset Voltage | 2 mV max at 25°C; ensures <±10 mV error in unity-gain buffer configurations over industrial temperature range |
| Unity-Gain Bandwidth | 1 MHz (temperature compensated); supports stable closed-loop gain ≥1 with predictable phase margin in active filters |
| Supply Current per Amplifier | 500 µA typical; allows dual op-amp operation on coin-cell batteries for >1-year life in low-duty-cycle sensor nodes |
| Input Common-Mode Range | 0 V to (V+ − 1.5 V); permits direct connection of grounded transducers without level-shifting circuitry |
| Output Voltage Swing | Within 20 mV of ground and within 2 V of V+ (RL = 10 kΩ); enables true single-supply signal acquisition from 0 V reference |
| Large-Signal Voltage Gain | 25 V/mV min; provides ≥60 dB open-loop gain at 10 V output swing-sufficient for precision DC amplification |
Pinout & Package
LM2904ITP/NOPB uses an 8-bump DSBGA (YPB) package measuring 1.31 mm × 1.31 mm with 0.5-mm pitch. This chip-scale package supports high-density PCB layouts and automated assembly in space-constrained applications such as portable instrumentation and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Output, Channel A | Amplified output of first op-amp; capable of sourcing/sinking ≥20 mA and swinging to ground |
| 2 (−INA) | Inverting Input, Channel A | Differential input node; accepts signals down to 0 V and tolerates −0.3 V transient |
| 3 (+INA) | Non-inverting Input, Channel A | Differential input node; same voltage range and bias characteristics as −INA |
| 4 (GND / V−) | Ground / Negative Supply | Reference for single-supply operation; serves as return path for both amplifiers' bias currents |
| 5 (+INB) | Non-inverting Input, Channel B | Second op-amp's high-impedance input; electrically identical to +INA |
| 6 (−INB) | Inverting Input, Channel B | Second op-amp's differential input; shares same ESD protection and common-mode limits as channel A |
| 7 (OUTB) | Output, Channel B | Independent output stage; no crosstalk with OUTA above −120 dB (1 kHz–20 kHz) |
| 8 (V+) | Positive Supply | Single power rail input; supplies both amplifiers; current draw independent of voltage magnitude |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | PNP input transistors enable common-mode voltage down to 0 V-eliminating level-shifters in grounded sensor interfaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | SOIC-8 package; wider operating temperature (0°C to 70°C vs. −40°C to 85°C); higher input offset (9 mV max) | Preferred for cost-sensitive commercial-grade designs where extended temperature range is unnecessary | Select LM358DR only when DSBGA footprint is not required and industrial temperature grade is not needed |
| TLV2462IDR | Rail-to-rail input/output; lower input offset (2 mV typ); higher supply current (550 µA per amp); 6 MHz bandwidth | Suitable for higher-precision, higher-speed applications where rail-to-rail swing and faster settling are critical | Choose TLV2462IDR when signal chain requires full rail-to-rail performance and bandwidth beyond 1 MHz |
Compared with LM358DR, LM2904ITP/NOPB offers superior temperature range and lower input offset for industrial use; compared with TLV2462IDR, it trades bandwidth and rail-to-rail capability for lower power and proven robustness in legacy 4–20 mA systems.

FAQ
What is the maximum supply voltage for LM2904ITP/NOPB?
The absolute maximum supply voltage for LM2904ITP/NOPB is 26 V for single-supply operation (or ±13 V dual supply), as specified in Section 6.1 of the official datasheet. Exceeding this limit risks permanent damage. Recommended operating range is 3 V to 26 V, with stable performance across this span due to supply-independent biasing.
Does LM2904ITP/NOPB support rail-to-rail output swing?
LM2904ITP/NOPB does not provide rail-to-rail output swing. Its output can swing to within approximately 20 mV of ground and within 2 V of V+ (at RL = 10 kΩ), as confirmed in Section 6.6 Electrical Characteristics. This ground-swing capability-combined with input common-mode range including ground-makes it ideal for single-supply systems, but it cannot reach the positive rail.
What is the input offset voltage specification for LM2904ITP/NOPB?
The input offset voltage for LM2904ITP/NOPB is 2 mV maximum at 25°C, with a typical value of 1 mV, per Section 6.6 of the datasheet. Over the full −40°C to +85°C industrial temperature range, the offset drift is 7 µV/°C typical-enabling predictable calibration in precision analog front-ends without frequent recalibration.
Can LM2904ITP/NOPB operate from a 3.3 V supply?
Yes, LM2904ITP/NOPB is fully specified to operate from a 3.3 V single supply. Its minimum recommended supply voltage is 3 V, and all key parameters-including input common-mode range (0 V to 1.8 V), output swing (to within 20 mV of ground), and 1 MHz bandwidth-are guaranteed at this rail. This makes LM2904ITP/NOPB compatible with modern 3.3 V digital systems without level translation.
What package type is used by LM2904ITP/NOPB?
LM2904ITP/NOPB uses an 8-bump DSBGA (Die Size Ball Grid Array) package, designated YPB in TI documentation, with nominal body size 1.31 mm × 1.31 mm and 0.5-mm ball pitch. This chip-scale package is distinct from SOIC, PDIP, or TO-99 variants and is optimized for space-constrained PCB layouts in portable and modular industrial electronics.
