Product details
Overview
UA741CPSRE4 from Texas Instruments is a general-purpose operational amplifier in an 8-pin SO (PS) package, characterized for 0°C to 70°C operation. It delivers ±14.95 V peak output swing into 10 kΩ, 0.5 V/µs slew rate, and 20–200 V/mV open-loop gain with internal frequency compensation. It is used in voltage-follower circuits requiring latch-up immunity and short-circuit protection.
For engineers reviewing the UA741CPSRE4 datasheet, UA741CPSRE4 pinout, UA741CPSRE4 application, or UA741CPSRE4 equivalent, key selection criteria include input offset voltage (0.3–7.5 mV), common-mode input range (±12 V), supply current (0.13–3.3 mA), thermal resistance (119.7 °C/W), and SO package compatibility with surface-mount assembly.
Technical Context
The UA741CPSRE4 implements a classic bipolar-input op-amp architecture with internally compensated dominant-pole response, eliminating need for external compensation. Its high common-mode input voltage range (±12 V) and absence of latch-up enable stable operation in unity-gain follower configurations across industrial temperature ranges.
It features dual power supply operation (±5 V to ±15 V), short-circuit protected output capable of ±80 mA, and input bias current as low as 0.01 nA at 25°C. The device uses NPN input transistors and includes dedicated offset-null pins in earlier variants-though per Revision H (2026), pins 1 and 5 are NC in the PS package configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports dual-rail analog signal conditioning without rail-to-rail constraints |
| Input Offset Voltage | 0.3–7.5 mV - determines DC error in precision amplification stages; affects accuracy in sensor front-ends |
| Slew Rate | 0.5 V/µs - limits large-signal bandwidth to ~80 kHz; suitable for audio and control loops, not RF |
| Open-Loop Gain | 20–200 V/mV (86–106 dB) - enables stable closed-loop gain up to ~100 with adequate phase margin |
| Common-Mode Input Range | ±12 V - allows input signals near supply rails without clipping in non-inverting configurations |
| Output Short-Circuit Current | ±80 mA - provides robust fault tolerance during transient overloads or miswiring |
| Input Resistance | 540 GΩ - minimizes loading on high-impedance sources like piezoelectric sensors or photodiodes |
Pinout & Package
UA741CPSRE4 uses an 8-pin Small Outline (SO) package (PS), 6.20 mm × 5.30 mm body size, RoHS-compliant, with NIPDAU lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - unused; must be left floating or tied to ground per layout best practice |
| 2 | IN− | Inverting input - receives feedback signal in standard op-amp configurations |
| 3 | IN+ | Noninverting input - accepts reference or sensor signal in follower or amplifier topologies |
| 4 | VCC− | Negative supply rail - connects to −5 V to −15 V; requires local 0.1 µF ceramic bypass |
| 5 | NC | No internal connection - unused; no offset-null function in PS package per Revision H |
| 6 | OUT | Amplified output - drives loads ≥2 kΩ; limited by ±10 V swing at 2 kΩ and ±14.95 V at 10 kΩ |
| 7 | VCC+ | Positive supply rail - connects to +5 V to +15 V; requires local 0.1 µF ceramic bypass |
| 8 | NC | No internal connection - unused; no internal tie to die; avoid routing sensitive traces nearby |
Key Features
| Feature | Design Value |
|---|---|
| Internal frequency compensation | Enables stable unity-gain operation without external capacitors - reduces BOM count and layout complexity |
| Short-circuit protection | Withstands indefinite output-to-rail shorts at ±80 mA - improves system reliability in motor drive or actuator interfaces |
| No latch-up behavior | Prevents destructive parasitic thyristor conduction during overvoltage or ESD events - critical for unregulated supply environments |
| Large common-mode input range | ±12 V at full temperature range - supports direct interfacing with industrial ±10 V sensor outputs |
| High input resistance | 540 GΩ typical - preserves signal integrity from microamp-level sources like pH electrodes or thermopiles |
Applications
| Audio Signal Conditioning | Industrial Sensor Interface |
|---|---|
Use Scenario: Amplifying line-level analog audio signals in pro-audio mixer channel strips before ADC conversion. IC Role / Device Role / Timing Role: Noninverting amplifier with fixed gain (e.g., 2×) providing DC-coupled buffering and level-shifting. Use Value: Low input bias current (0.01 nA typ) prevents capacitor discharge in coupling networks; ±14.95 V output swing ensures headroom for 20 Vpp signals. | Use Scenario: Conditioning output from ±10 V industrial pressure transducers in PLC analog input modules. IC Role / Device Role / Timing Role: Unity-gain voltage follower isolating high-impedance sensor output from downstream multiplexer or filter stages. Use Value: ±12 V common-mode range matches transducer output span; no latch-up ensures robustness against field wiring faults. |
| DVD Player Analog Output Stage | Legacy Test Equipment Amplifier |
Use Scenario: Driving composite video or stereo audio outputs in consumer DVD playback devices. IC Role / Device Role / Timing Role: Fixed-gain buffer stage delivering low-distortion analog signals to RCA connectors. Use Value: Internal compensation eliminates tuning; ±80 mA short-circuit current protects against accidental cable shorts during hot-plug events. | Use Scenario: Building calibrated gain blocks in benchtop oscilloscope vertical amplifiers or function generator output stages. IC Role / Device Role / Timing Role: Precision DC-coupled amplifier with trimmable offset (via external circuitry) for zero-reference calibration. Use Value: 0.3 mV typical input offset enables sub-mV nulling; 540 GΩ input resistance avoids loading on calibration potentiometers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Single-supply rated (3–32 V), lower input offset (2 mV max), rail-to-rail output not supported | Better suited for battery-powered or single-rail systems; lacks dual-supply symmetry of UA741CPSRE4 | Select when operating from 5 V or 12 V single supply and DC accuracy requirements are moderate |
| TL072CDR | JFET-input (50 pA bias), higher slew rate (13 V/µs), wider supply range (±5–±18 V) | Superior for high-frequency audio or fast-settling instrumentation where bandwidth >100 kHz is required | Select when low noise, low distortion, and >3 MHz GBW are needed - not drop-in compatible due to different pinout |
Compared with LM358DR and TL072CDR, UA741CPSRE4 offers proven dual-supply stability, predictable compensation, and legacy design continuity - making it preferred for retrofitting or maintaining existing ±15 V analog signal paths where bandwidth demands remain below 100 kHz.

FAQ
What is the maximum operating temperature range for the UA741CPSRE4?
The UA741CPSRE4 is characterized for operation from 0°C to 70°C ambient temperature. Its absolute maximum junction temperature is 150°C, and storage temperature range extends from –65°C to 150°C. Thermal resistance (RθJA) is 119.7 °C/W in the PS package, so power dissipation must be managed to maintain safe junction temperatures under load.
Does the UA741CPSRE4 require external frequency compensation?
No, the UA741CPSRE4 includes internal frequency compensation, enabling stable unity-gain operation without external capacitors. This simplifies PCB layout and eliminates tuning steps - a defining feature of the µA741 architecture confirmed in TI's SLOS094H datasheet Section 3 and Figure 4-1.
What are the functions of pins 1 and 5 on the UA741CPSRE4?
Pins 1 and 5 on the UA741CPSRE4 are marked NC (No Connection) per TI's SLOS094H Revision H (2026). Unlike older µA741 variants, the PS package does not implement internal offset-null circuitry - these pins have no internal die connection and must be left unconnected or grounded per layout guidelines.
Can the UA741CPSRE4 operate from a single 5 V supply?
The UA741CPSRE4 is specified for dual-supply operation (±5 V to ±15 V) and is not optimized for single-supply use. While it may function with asymmetric supplies (e.g., +5 V and ground), its common-mode input range (±12 V) and output swing (±10 V min) degrade significantly - use LM358 or TLV2462 for true 5 V single-supply designs.
Is the UA741CPSRE4 RoHS compliant and what is its moisture sensitivity level?
Yes, the UA741CPSRE4 is RoHS compliant with NIPDAU lead finish and carries an MSL Level-1 rating (260°C peak reflow, unlimited floor life). Its PS package is qualified for standard surface-mount assembly processes without dry-pack requirements, as documented in TI's Package Option Addendum dated 17-Nov-2025.
