Product details
Overview
LM7301IM5X from Texas Instruments is a rail-to-rail input-output operational amplifier in a 5-pin SOT-23 package, delivering 4.5 MHz gain-bandwidth, 0.56 mA supply current, ±21 V/µs slew rate, and operation from 2.7 V to 32 V. It enables high-precision signal conditioning in space-constrained portable instrumentation and ADC buffer stages.
For engineers reviewing the LM7301IM5X datasheet, LM7301IM5X pinout, LM7301IM5X application, or LM7301IM5X equivalent, this page provides verified pin functions, real-world dynamic range data (0.07 V to 4.93 V output swing at 5 V), CMVR of −0.1 V to 5.1 V, PSRR of 104 dB, and validated alternatives for low-power analog front-end design.
Technical Context
The LM7301IM5X employs a slew-boosted architecture enabling 21 V/µs typical slew rate above 150 mV input differential voltage, while maintaining < 0.01 nA input bias current and 540 GΩ input resistance. Its rail-to-rail input extends 0.1 V beyond both rails, and output swing reaches within 70 mV of each rail at 5 V supply with 10 kΩ load.
Designed for single- or dual-supply operation, it achieves 93 dB CMRR and 104 dB PSRR across 2.7 V–32 V, supporting stable performance in noisy industrial and battery-powered environments without external level-shifting circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9061IDBVR | Lower 0.52 mA supply current, 10 MHz GBW, but only 1.8 V–5.5 V supply range and 1.2 V/µs slew rate | Better for ultra-low-power 3.3 V IoT nodes; unsuitable for 24 V industrial supplies or fast transient response | Select TLV9061IDBVR when supply is ≤5.5 V and bandwidth >4.5 MHz is required; avoid for wide-supply or high-slew applications |
| OPA333AIDBVR | Zero-drift architecture, 0.01 µV/°C offset drift, but 350 kHz GBW and 0.16 V/µs slew rate | Superior DC precision for weigh scales or medical sensors; cannot support >10 kHz AC-coupled signal paths | Select OPA333AIDBVR for sub-µV offset stability over temperature; use LM7301IM5X when AC performance dominates |
Compared with TLV9061IDBVR and OPA333AIDBVR, LM7301IM5X uniquely balances wide 2.7 V–32 V operation, 4.5 MHz bandwidth, and 21 V/µs slew rate in a 5-pin SOT-23-making it the only choice for portable 24 V instrumentation requiring both DC accuracy and fast transient fidelity.

FAQ
What is the maximum supply voltage rating for LM7301IM5X?
The absolute maximum supply voltage (V+ − V−) for LM7301IM5X is 35 V, with recommended operating range from 2.7 V to 32 V. Operation at 32 V is fully characterized per datasheet Section 5.3, supporting industrial 24 V systems with 20% margin. Exceeding 35 V risks permanent damage per Absolute Maximum Ratings table.
Does LM7301IM5X support true rail-to-rail input beyond the supply rails?
Yes, LM7301IM5X provides greater-than-rail-to-rail input common-mode voltage range: −0.1 V to 5.1 V at 5 V supply. This allows input signals 100 mV below ground or 100 mV above V+, eliminating need for external level-shifting in sensor interfaces like thermocouples or bridge amplifiers.
What is the typical output voltage swing of LM7301IM5X at 5 V supply?
At 5 V supply and 10 kΩ load, LM7301IM5X delivers 0.07 V to 4.93 V output swing (4.86 Vpp), confirmed in Section 5.5 Electrical Characteristics. This rail-to-rail capability maximizes dynamic range for 12-bit+ ADCs, with headroom reduced to just 70 mV at each rail.
How does the slew-boosted architecture of LM7301IM5X affect signal fidelity?
LM7301IM5X uses a slew-boosted architecture achieving 21 V/µs typical slew rate for input differentials >150 mV, while maintaining <0.006% THD at 10 kHz per Section 5.6. This enables clean amplification of fast transients without clipping, unlike standard architectures limited to ~0.5 V/µs in linear region.
Is LM7301IM5X pin-compatible with other SOT-23-5 op-amps?
LM7301IM5X follows standard SOT-23-5 pinout (OUT, V−, +IN, −IN, V+) per Figure 4-2, matching industry convention. However, electrical characteristics-including 21 V/µs slew rate, 4.5 MHz GBW, and −0.1 V to 5.1 V CMVR-are unique to LM7301IM5X; direct replacement requires validation of these parameters in target circuit.
