Product details
Overview
LM7301IM/NOPB from Texas Instruments is a rail-to-rail input-output operational amplifier in an 8-pin SOIC package, delivering 4.5 MHz gain-bandwidth, 0.56 mA supply current, and rail-to-rail output swing (0.07 V to 4.93 V at 5 V supply) for precision signal conditioning in low-power portable instrumentation.
For engineers reviewing the LM7301IM/NOPB datasheet, LM7301IM/NOPB pinout, LM7301IM/NOPB application, or LM7301IM/NOPB equivalent, key selection criteria include its −0.1 V to 5.1 V input common-mode range, 104 dB PSRR, 93 dB CMRR, and compatibility with 2.7 V to 32 V single-supply operation in space-constrained designs.
Technical Context
The LM7301IM/NOPB uses a slew-boosted architecture enabling 21 V/µs slew rate for large-signal transients while maintaining 36 nV/√Hz input voltage noise at 1 kHz. Its input stage supports common-mode voltages beyond the rails (−0.1 V to 5.1 V at 5 V), eliminating input clipping concerns in high-precision buffer applications.
It achieves full rail-to-rail output swing (0.07 V to 4.93 V into 10 kΩ at 5 V), maximizing dynamic range in low-voltage systems. The device operates across 2.7 V to 32 V, with 540 GΩ input resistance and 0.03 mV typical input offset voltage at 25°C - critical for high-gain DC-coupled stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 4.5 MHz - supports stable unity-gain and moderate-gain configurations up to ~100 kHz without phase margin loss. |
| Supply Current | 0.56 mA at 25°C - enables multi-channel amplification in battery-powered devices with minimal quiescent power impact. |
| Input Common-Mode Range | −0.1 V to 5.1 V at 5 V supply - accepts signals below ground or above V+, simplifying sensor interfacing without level-shifting. |
| Rail-to-Rail Output Swing | 0.07 V to 4.93 V into 10 kΩ - delivers >98% of full supply range, preserving ADC resolution in single-supply data acquisition. |
| PSRR / CMRR | 104 dB / 93 dB - rejects supply ripple and common-mode interference in noisy industrial or mixed-signal PCB environments. |
| Input Offset Voltage | 0.03 mV typical at 25°C - ensures <1 LSB error in 12-bit systems with 5 V full-scale, reducing calibration overhead. |
| Slew Rate | 21 V/µs - handles fast step inputs (e.g., pulse conditioning) without distortion, unlike legacy 1–2 V/µs general-purpose op-amps. |
Pinout & Package
LM7301IM/NOPB is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, optimized for thermal performance (RθJA = 165 °C/W) and board-level reliability in industrial temperature ranges (−40°C to +85°C).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No connection | Unused terminal; must remain unconnected to avoid parasitic coupling or latch-up risk. |
| 2 | Inverting input | Differential input node accepting feedback network; high impedance (540 GΩ) minimizes loading on preceding stage. |
| 3 | Noninverting input | High-impedance input for reference or sensor signal; supports common-mode voltages beyond supply rails. |
| 4 | Negative supply | Ground or negative rail connection; enables true single-supply operation when tied to 0 V. |
| 5 | No connection | Unused terminal; electrically isolated per internal die layout - no routing or soldering required. |
| 6 | Output | Capable of sourcing/sinking ±75 mA short-circuit current; drives 2 kΩ loads with <0.22 V headroom at 5 V. |
| 7 | Positive supply | Accepts 2.7 V to 32 V; bypass capacitor (0.1 µF ceramic) required adjacent to pin for stability and noise rejection. |
| 8 | No connection | Unused terminal; internal die bond wire not connected - leave floating per TI design guidance. |
Key Features
| Feature | Design Value |
|---|---|
| Greater-than-rail input range | −0.1 V to 5.1 V at 5 V supply - eliminates need for external level shifters when interfacing bipolar sensors or DACs. |
| Rail-to-rail output swing | 0.07 V to 4.93 V into 10 kΩ - maximizes usable voltage range for ADC drivers operating on 5 V rails. |
| Low 0.56 mA quiescent current | Enables integration of multiple channels in portable instruments without compromising battery life beyond 100 hours. |
| High 104 dB PSRR | Maintains signal integrity in systems sharing noisy switch-mode power supplies with digital subsystems. |
| Wide 2.7 V to 32 V supply range | Supports direct use across automotive (12 V), industrial (24 V), and portable (3.3 V/5 V) platforms without redesign. |
Applications
| Portable Instrumentation | Signal Conditioning Amplifiers/ADC Buffers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CDR | Lower 6.4 MHz GBW; 0.65 mA supply current; 2.7 V to 6 V supply range only. | Optimized for low-voltage, low-noise dual-channel apps; lacks 32 V tolerance and extended CMVR. | Select TLV2462CDR only if operating strictly ≤6 V and needing dual-channel integration in same footprint. |
| OPA333AIDR | Zero-drift architecture; 0.17 µV/°C TCVOS; 0.17 mA supply current; 1.8 V to 5.5 V range. | Better DC precision for µV-level measurements; insufficient for 24 V industrial signal chains. | Choose OPA333AIDR when ultra-low drift dominates over wide supply range and high-voltage operation. |
Compared with TLV2462CDR and OPA333AIDR, LM7301IM/NOPB uniquely balances wide 2.7 V–32 V operation, rail-to-rail I/O, and 4.5 MHz bandwidth - making it the only option among the three suitable for universal single-supply industrial sensor interfaces requiring both precision and voltage flexibility.

FAQ
What is the maximum supply voltage rating for LM7301IM/NOPB?
The LM7301IM/NOPB has an absolute maximum supply voltage (V+ − V−) of 35 V, with recommended operating range from 2.7 V to 32 V. Operation beyond 32 V risks exceeding safe junction temperature limits and is not guaranteed for parametric performance per the datasheet.
Does LM7301IM/NOPB support true single-supply operation with input signals below ground?
Yes, LM7301IM/NOPB supports input common-mode voltages down to −0.1 V at 5 V supply, enabling acceptance of slightly negative signals in single-supply configurations without external level shifting - confirmed by TI's "greater than rail-to-rail input" specification.
What is the typical input offset voltage of LM7301IM/NOPB at room temperature?
The typical input offset voltage of LM7301IM/NOPB is 0.03 mV at TA = 25°C, with a maximum of 6 mV across the full operating temperature range (−40°C to +85°C), ensuring high DC accuracy in precision gain stages and sensor interfaces.
Can LM7301IM/NOPB drive capacitive loads without instability?
LM7301IM/NOPB is specified for stable operation with capacitive loads up to 100 pF per the datasheet; larger loads require isolation resistors or careful compensation. Its internal compensation is optimized for unity-gain stability but degrades with >100 pF directly at the output pin.
Is LM7301IM/NOPB pin-compatible with other TI op-amps in SOIC-8 packages?
No, LM7301IM/NOPB has a unique pinout with three no-connect pins (1, 5, 8); it is not pin-compatible with standard dual or quad SOIC-8 op-amps like LM358 or TL072. Layout reuse requires verification against the official LM7301IM/NOPB pin configuration diagram.
