Product details
Overview
TL052AIP from Texas Instruments is a dual JFET-input operational amplifier with on-chip offset-voltage trimming, 4.5 MHz unity-gain bandwidth, 17.8 V/μs slew rate (±15 V), and 0.57 mV max input offset voltage at 25°C. It serves as a precision upgrade to TL072/TL082 in high-impedance sensor interfaces and low-noise audio preamplifiers.
For engineers reviewing the TL052AIP datasheet, TL052AIP pinout, TL052AIP application, or TL052AIP equivalent, key selection criteria include input offset voltage stability, FET-input impedance (>10¹² Ω), dual-supply operation (±5 V to ±15 V), and SOIC-8 package compatibility with legacy TL07x/TL08x layouts.
Technical Context
The TL052AIP uses enhanced JFET input stages to achieve ultra-low input bias current (≤100 pA at 25°C) and high input resistance (10¹² Ω), enabling accurate amplification of microvolt-level signals from piezoelectric sensors or photodiode transimpedance nodes. Its trimmed offset and low 10.8 nV/√Hz input voltage noise at 1 kHz support DC-coupled instrumentation chains.
Designed for dual-supply operation, the device specifies common-mode input range from –11 V to +11 V (±15 V supply) and output swing to within 1.3 V of rails (RL = 2 kΩ). It requires external DC biasing for single-supply use and exhibits 106 dB crosstalk attenuation between channels - critical for multi-channel data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | 0.57 mV max at 25°C - enables sub-millivolt DC accuracy without external nulling circuitry |
| Unity-gain bandwidth | 4.5 MHz - supports stable closed-loop gain ≥10 up to ~450 kHz |
| Slew rate | 17.8 V/μs (±15 V) - allows full-scale 10 Vpp output at ≤1.8 MHz without distortion |
| Input bias current | 20 pA typ at 25°C - preserves signal integrity with >1 MΩ source impedances |
| Common-mode rejection | 92 dB min at 25°C - rejects power-supply ripple and shared-noise coupling in differential front-ends |
| Supply voltage range | ±5 V to ±15 V - compatible with standard analog test equipment and industrial control rails |
| Input voltage noise | 10.8 nV/√Hz at 1 kHz - lower than TL082 (18 nV/√Hz), suitable for low-frequency precision sensing |
Pinout & Package
TL052AIP 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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier channel 1 output - drives loads ≥2 kΩ with rail-to-rail swing capability |
| 1IN– | Input | Inverting input, channel 1 - high-impedance node (10¹² Ω) sensitive to PCB leakage |
| 1IN+ | Input | Non-inverting input, channel 1 - used for unity-gain buffers or differential pairs |
| VCC– | Power | Negative supply rail - must be connected to system ground or negative rail; no internal connection to substrate |
| 2IN+ | Input | Non-inverting input, channel 2 - electrically isolated from channel 1; 106 dB crosstalk attenuation |
| 2IN– | Input | Inverting input, channel 2 - shares same process-trimmed offset characteristics as channel 1 |
| 2OUT | Output | Amplifier channel 2 output - independently buffered; supports dual-channel signal conditioning |
| VCC+ | Power | Positive supply rail - decoupling capacitor (0.1 μF) required within 1 cm of pin |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to 0.57 mV max (vs. 1.5 mV for TL082), lowering calibration overhead in production test |
| FET-input architecture | Delivers 10¹² Ω input resistance and ≤100 pA input bias current - essential for electrometer-grade measurements |
| Low 10.8 nV/√Hz input voltage noise | Enables clean amplification of low-level AC signals (e.g., microphone preamps) without added filtering |
| Pin-compatible with TL072/TL082 | Allows drop-in replacement in existing SOIC-8 layouts without PCB revision or footprint change |
| 106 dB inter-channel crosstalk | Prevents signal bleed between channels in dual-path filters or stereo audio circuits |
Applications

IC Role / Device Role / Timing Role: Independent dual-channel signal conditioner with 106 dB channel isolation. Use Value: Crosstalk attenuation prevents interference between channels during multiplexed ADC sampling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CP | Higher 1.5 mV max input offset voltage; 18 nV/√Hz input noise at 1 kHz; no on-chip trimming | Acceptable where cost sensitivity outweighs precision requirements; less suitable for DC-critical sensor paths | Choose TL072CP only if budget constraints override need for sub-millivolt DC accuracy and lower noise |
| OPA2134PA | Lower 0.5 mV max VIO; 8 nV/√Hz noise; rail-to-rail output; higher 8 MHz GBW; SO-8 package | Better for battery-powered audio or portable instrumentation needing extended output swing and wider bandwidth | Choose OPA2134PA when rail-to-rail output or <8 nV/√Hz noise is mandatory - but verify layout compatibility with TL052AIP's SOIC-8 footprint |
Compared with TL072CP, TL052AIP delivers tighter offset control and lower noise for precision DC sensing; compared with OPA2134PA, it offers proven legacy compatibility and lower cost, though with reduced bandwidth and non-rail-to-rail output.

FAQ
What is the maximum supply voltage rating for TL052AIP?
The TL052AIP has an absolute maximum supply voltage rating of ±18 V. It is fully specified for operation across ±5 V to ±15 V, with recommended operating conditions ensuring optimal performance and reliability. Exceeding ±18 V risks permanent damage per the Absolute Maximum Ratings table in the SLOS178B datasheet.
Does TL052AIP support single-supply operation?
TL052AIP is designed for dual-supply operation and does not feature rail-to-rail input or output. Single-supply use requires external DC biasing of inputs to mid-supply (e.g., using TI's TLE2426 virtual ground generator) and careful attention to common-mode input limits and output swing constraints - as detailed in Section 2 of the TL052AIP datasheet.
How does TL052AIP differ from TL082 in practical circuit design?
TL052AIP improves upon TL082 with on-chip offset trimming (0.57 mV vs. 3 mV max), lower 10.8 nV/√Hz input noise (vs. 18 nV/√Hz), and higher 17.8 V/μs slew rate (vs. 13 V/μs). These differences enable cleaner DC accuracy and faster transient response in sensor interfaces and audio paths - without changing PCB layout due to SOIC-8 pin compatibility.
What is the input bias current specification for TL052AIP at 85°C?
At 85°C, the TL052AIP exhibits a maximum input bias current of 0.7 nA (700 pA), as specified in Section 4.5 of the SLOS178B datasheet under TL05xAI conditions. This remains significantly lower than bipolar-input op-amps, preserving high-impedance node integrity even in elevated-temperature industrial environments.
Can unused channels of TL052AIP be left floating?
No - unused channels of TL052AIP must not be left floating. Per Section 5.1.2 of the datasheet, they should be configured as grounded unity-gain followers (non-inverting input tied to ground, output connected to inverting input) to prevent oscillation and ensure stable quiescent current. Leaving inputs unconnected risks instability and increased power consumption.
