Product details
Overview
UA741CPG4 from Texas Instruments is a general-purpose operational amplifier in an 8-pin PDIP package, featuring ±15 V supply operation, ±12 V common-mode input range, 0.3 mV typical input offset voltage, 0.005 nA typical input offset current, and short-circuit protection. It serves as a voltage-follower or basic gain stage in analog signal conditioning circuits.
For engineers reviewing the UA741CPG4 datasheet, UA741CPG4 pinout, UA741CPG4 application, or UA741CPG4 equivalent, key selection criteria include its internal frequency compensation (no external components required), latch-up immunity, wide differential input voltage range (±15 V), and suitability for industrial-grade 0°C to 70°C operation.
Technical Context
The UA741CPG4 implements a classic bipolar-input op-amp architecture with internal dominant-pole compensation, enabling stable unity-gain operation without external capacitors. Its high input resistance (540 GΩ) and low input bias current (0.01 nA typ) support precision DC-coupled configurations.
It operates from dual supplies of ±5 V to ±15 V, delivers ±12 V output swing into 10 kΩ, and provides 0.5 V/µs slew rate with 0.3 µs rise time. The device lacks offset-null pins in the PDIP variant per Revision H (pins 1 and 5 are NC), distinguishing it from legacy µA741C variants with adjustable null capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports standard dual-rail analog systems without level-shifting |
| Input Offset Voltage (typ) | 0.3 mV - enables accurate DC amplification with minimal initial error |
| Input Bias Current (typ) | 0.01 nA - reduces voltage error across high-impedance feedback networks |
| Common-Mode Input Range | ±12 V - allows rail-to-rail input operation within ±15 V supplies |
| Slew Rate | 0.5 V/µs - limits large-signal bandwidth to ~80 kHz but ensures stability in low-frequency control loops |
| Output Short-Circuit Current | ±80 mA - provides robust fault tolerance without external current limiting |
| Input Resistance | 540 GΩ - minimizes loading on high-Z sensor sources like piezoelectric transducers |
Pinout & Package
UA741CPG4 is housed in an 8-pin Plastic Dual Inline Package (PDIP) with 9.81 mm × 6.35 mm body size and through-hole mounting. Pin 1 and Pin 5 are No Connection (NC) per latest revision; offset-null functionality is not available in this variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - unused; no external circuitry required |
| 2 | IN– | Inverting input - accepts feedback network for closed-loop gain configuration |
| 3 | IN+ | Noninverting input - connects to reference or sensor signal in follower/buffer mode |
| 4 | VCC– | Negative supply terminal - must be connected to system ground or negative rail |
| 5 | NC | No internal connection - unused; no external circuitry required |
| 6 | OUT | Amplified output - drives loads ≥2 kΩ with ±12 V swing at ±15 V supplies |
| 7 | VCC+ | Positive supply terminal - requires 0.1 µF ceramic bypass capacitor to ground |
| 8 | NC | No internal connection - unused; no external circuitry required |
Key Features
| Feature | Design Value |
|---|---|
| Internal frequency compensation | Enables stable unity-gain operation without external capacitor - simplifies PCB layout and reduces BOM count |
| Short-circuit protection | Withstands indefinite output-to-rail shorts up to ±80 mA - eliminates need for external current-limiting resistors |
| No latch-up behavior | Prevents destructive output phase reversal during overdrive or common-mode excursion - improves reliability in transient-prone systems |
| Large differential input voltage range | ±15 V - accommodates input signals exceeding supply rails in comparator-like applications |
| Wide operating temperature range | 0°C to 70°C - certified for commercial and industrial ambient environments without derating |
Applications
| Audio Signal Buffering | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Amplifying low-level microphone or line-level audio signals before ADC sampling in pro-audio mixers. IC Role / Device Role / Timing Role: Voltage-follower buffer isolating source impedance from downstream stages while preserving signal integrity. Use Value: High input resistance (540 GΩ) prevents loading of high-impedance transducer outputs; ±12 V output swing supports full-scale dynamic range into 10 kΩ loads. |
Use Scenario: Conditioning thermocouple or strain gauge outputs in PLC analog input modules. IC Role / Device Role / Timing Role: Precision DC-coupled amplifier with low input offset (0.3 mV typ) and negligible bias current (0.01 nA). Use Value: Enables sub-millivolt-level measurement accuracy without trimming; short-circuit protection safeguards against field-wiring faults. |
| DVD Player Analog Output Stage | Legacy Industrial Control Loop |
|
Use Scenario: Driving composite video or audio DAC outputs to RCA connectors in DVD recorders and players. IC Role / Device Role / Timing Role: Low-distortion unity-gain buffer ensuring impedance matching and signal fidelity. Use Value: Stable operation with no external compensation allows compact layout; ±15 V supply compatibility matches legacy AV subsystem rails. |
Use Scenario: Implementing PID integrator or error amplifier in motor drive feedback circuits with discrete transistor power stages. IC Role / Device Role / Timing Role: Robust op-amp for analog loop compensation where latch-up immunity and rail-tolerant inputs prevent lockup during transients. Use Value: Large common-mode range (±12 V) handles back-EMF spikes; internal compensation avoids timing-sensitive external component selection. |
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), no short-circuit protection, dual-channel | Better suited for battery-powered or single-rail systems; lacks bipolar supply headroom and fault tolerance | Select LM358DR only when operating from 0–5 V rails or requiring dual amplifiers in one package |
| TL081CP | JFET-input (50 pA IB), higher slew rate (13 V/µs), wider bandwidth (4 MHz), no internal compensation | Requires external compensation capacitor; superior AC performance but more layout-sensitive | Choose TL081CP for high-speed AC-coupled designs where bandwidth >100 kHz is critical and stability can be verified |
Compared with LM358DR and TL081CP, UA741CPG4 offers unique value in legacy dual-supply systems requiring guaranteed stability, short-circuit resilience, and proven latch-up immunity-without demanding external compensation or ultra-low input current.

FAQ
What is the maximum supply voltage for UA741CPG4?
The absolute maximum supply voltage for UA741CPG4 is ±18 V. Operation beyond this rating risks permanent damage. For reliable continuous operation, TI specifies ±5 V to ±15 V as the recommended range. At ±15 V, UA741CPG4 delivers ±12 V output swing into 10 kΩ and maintains specified electrical characteristics across 0°C to 70°C.
Does UA741CPG4 support input offset voltage adjustment?
No. UA741CPG4 does not support offset voltage adjustment. Per Revision H of the datasheet, pins 1 and 5 are designated as No Connection (NC) in the PDIP package - unlike earlier µA741C variants that included offset-null terminals. This simplifies layout but requires system-level calibration if sub-millivolt DC accuracy is needed.
Can UA741CPG4 operate from a single supply?
UA741CPG4 is optimized for dual-supply operation (±5 V to ±15 V) and does not guarantee rail-to-rail input or output on single supplies. While it may function with a split virtual ground, TI does not characterize or recommend single-supply use. For true single-rail applications, consider purpose-built alternatives like LM358DR or TLC272CP.
What thermal considerations apply to UA741CPG4 in PDIP packaging?
UA741CPG4 in PDIP has a junction-to-ambient thermal resistance (RθJA) of 87.4°C/W. At 2.8 mA supply current and ±15 V supplies, power dissipation remains below 100 mW - well within safe limits at room temperature. No heatsink is required, but 0.1 µF ceramic bypass capacitors at each supply pin are mandatory to suppress noise-induced thermal drift.
Is UA741CPG4 RoHS compliant?
Yes. UA741CPG4 is RoHS compliant with lead finish/NiPdAu (NIPDAU) and meets JEDEC Level-1 moisture sensitivity requirements. The "G4" suffix denotes green (halogen-free) packaging per TI's material specifications, confirmed in the active orderable addendum for UA741CP and UA741CP.A variants.
