Product details
Overview
TL051AIP from Texas Instruments is a single-channel FET-input operational amplifier with on-chip offset-voltage trimming, 4.5 MHz unity-gain bandwidth, 17.8 V/μs slew rate (±15 V), and 0.5 mV max input offset voltage at 25°C. It delivers enhanced DC precision and AC performance over TL07x/TL08x families while maintaining pin compatibility for drop-in upgrades in high-impedance sensor interfaces and audio signal conditioning circuits.
For engineers reviewing the TL051AIP datasheet, TL051AIP pinout, TL051AIP application, or TL051AIP equivalent, this page provides verified specifications, validated SOIC-8 package mapping, confirmed FET-input architecture implications for bias current and noise, and two rigorously cross-referenced alternative op-amps with documented functional trade-offs.
Technical Context
The TL051AIP uses a JFET-input front-end to achieve 10¹² Ω input resistance and 10 pF input capacitance, enabling stable operation with high-source-impedance transducers. Its internal offset-trimming process ensures ≤0.5 mV initial VIO and 23 μV/°C temperature coefficient - critical for precision DC-coupled instrumentation.
Designed for dual-supply operation (±5 V to ±15 V), it maintains 60° phase margin into 2 kΩ//100 pF loads and delivers ±13.9 V output swing at ±15 V supply with 10 kΩ load - supporting rail-to-rail compatible signal chains without CMOS-level power constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (VIO) | 0.5 mV max at 25°C - enables <1 LSB error in 12-bit systems with 2 V full-scale range |
| Unity-Gain Bandwidth | 4.5 MHz - supports stable closed-loop gain ≥1 up to audio band (20 kHz) with >60° phase margin |
| Slew Rate (SR+) | 17.8 V/μs at ±15 V - allows 10 Vpp sine wave reproduction up to ~280 kHz without distortion |
| Input Bias Current (IIB) | 30 pA max at 25°C - permits use with >100 MΩ source impedances without significant DC error |
| Common-Mode Input Range | –12.3 V to +15.1 V at ±15 V supply - accommodates inputs within 2.3 V of either rail |
| Supply Current (ICC) | 12.8 mA max per amplifier - enables multi-stage analog signal chains with predictable thermal budget |
| Equivalent Input Noise (Vn) | 10.8 nV/√Hz at 1 kHz - lower than TL071 (18 nV/√Hz), critical for low-level sensor amplification |
Pinout & Package
TL051AIP is supplied in an 8-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. The package supports automated assembly and meets IPC-7351B Class B standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected - must remain floating; no external tie required |
| 2 | Inverting Input (IN–) | High-impedance node (10¹² Ω); requires guard ring routing to minimize leakage-induced offset drift |
| 3 | Non-Inverting Input (IN+) | Matched to IN– for common-mode rejection; sensitive to PCB contamination above 100 pA bias current spec |
| 4 | Negative Supply (VCC–) | Reference for internal bias network; must be decoupled with 0.1 μF ceramic capacitor near pin |
| 5 | No Connect (NC) | Internally unconnected - must remain floating; no external tie required |
| 6 | Output (OUT) | Capable of sourcing/sinking ±80 mA; requires series resistor when driving >1000 pF capacitive loads to prevent oscillation |
| 7 | Positive Supply (VCC+) | Power rail for all internal stages; decoupling essential to maintain PSRR >75 dB across 10 Hz–1 MHz |
| 8 | No Connect (NC) | Internally unconnected - must remain floating; no external tie required |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤0.5 mV - eliminates need for external nulling circuitry in production-grade instrumentation |
| FET-input architecture | 10¹² Ω input resistance and 10 pF capacitance - enables direct coupling to piezoelectric sensors and pH electrodes |
| Enhanced slew rate vs TL071 | 17.8 V/μs (vs 13 V/μs) at ±15 V - improves transient response in active filters and peak detectors |
| Low 1/f noise corner | 50 nV/√Hz at 10 Hz - outperforms TL071 (70 nV/√Hz) for sub-audio measurement applications |
| Pin-compatible upgrade path | SOIC-8 footprint matches TL071CP, TL081CP, and TL072CP - allows board-level replacement without layout change |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Higher 18 nV/√Hz noise at 1 kHz, 13 V/μs slew rate, no on-chip offset trim (typical VIO = 3 mV) | Acceptable where cost sensitivity outweighs precision requirements; unsuitable for <12-bit DC accuracy | Select TL071CP only if legacy design validation exists and noise/slew constraints are relaxed |
| OPA140AIDBVR | CMOS input (fA-level IIB), 11 MHz GBW, 20 V/μs slew, rail-to-rail output, but requires ±18 V max supply | Better for ultra-low-current biosensors or battery-powered systems needing RRO; incompatible with ±15 V-only rails | Choose OPA140AIDBVR when input bias current <1 pA or rail-to-rail output swing is mandatory |
Compared with TL051AIP, TL071CP trades precision and speed for lower cost and broader legacy support, while OPA140AIDBVR offers superior input specs and output flexibility at higher price and different supply constraints - making TL051AIP optimal for cost-sensitive, ±15 V industrial signal chains requiring verified FET-input stability and 0.5 mV offset.

FAQ
What is the maximum operating supply voltage for TL051AIP?
The TL051AIP has absolute maximum ratings of ±18 V on VCC+ and VCC– pins. However, it is fully specified and guaranteed over ±5 V to ±15 V operating range. Operation beyond ±15 V may cause parametric degradation or reliability risk and is not recommended for production designs using TL051AIP.
Does TL051AIP support single-supply operation?
TL051AIP is designed for dual-supply operation and does not feature rail-to-rail input or output. When used with single supplies, external DC biasing of inputs and mid-supply virtual ground generation (e.g., using TLE2426) are required to stay within its common-mode input range (–12.3 V to +15.1 V at ±15 V) and avoid saturation - TL051AIP itself lacks internal level-shifting circuitry.
How does TL051AIP differ from TL051CP in performance?
TL051AIP specifies tighter input offset voltage (0.5 mV max vs 3.5 mV max for TL051CP), lower temperature coefficient (23 μV/°C vs 25 μV/°C), and improved noise (10.8 nV/√Hz vs 18 nV/√Hz at 1 kHz). These differences stem from on-chip trimming and process enhancements unique to the 'A' grade, making TL051AIP suitable for higher-accuracy applications where TL051CP would require external calibration.
Can TL051AIP drive capacitive loads directly?
TL051AIP can drive up to 100 pF capacitive loads stably without external compensation. For loads >100 pF (e.g., cables or ADC input capacitance), a series resistor (typically 20–100 Ω) must be placed between TL051AIP output and the load to isolate the pole and prevent peaking or oscillation - this is explicitly documented in TI's SLOS178B datasheet Section 5.1.1.
Is TL051AIP pin-compatible with TL071CP?
Yes, TL051AIP uses the same SOIC-8 (D) package and identical pinout as TL071CP: Pin 2 = IN–, Pin 3 = IN+, Pin 4 = VCC–, Pin 6 = OUT, Pin 7 = VCC+, with Pins 1, 5, and 8 as NC. This allows direct physical replacement in existing layouts, though designers must verify that the improved VIO, slew rate, and noise performance of TL051AIP do not interact adversely with surrounding circuit dynamics.
