Product details
Overview
TL052IDRE4 from Texas Instruments is a dual FET-input operational amplifier engineered for precision analog signal conditioning in dual-supply systems. It delivers 4.5 MHz unity-gain bandwidth, 17.8 V/μs positive slew rate (±15 V), and 0.65 mV max input offset voltage (25°C, ±15 V) - enabling high-fidelity amplification of low-level sensor signals in test equipment and audio preamplifiers.
For engineers reviewing the TL052IDRE4 datasheet, TL052IDRE4 pinout, TL052IDRE4 application, or TL052IDRE4 equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel pin functions, real-world noise performance (10.8 nV/√Hz at 1 kHz), and validated alternatives for precision FET op-amp upgrades where low input bias current (≤100 pA) and high CMRR (≥92 dB) are required.
Technical Context
The TL052IDRE4 implements a JFET-input front-end with on-chip offset-voltage trimming, delivering improved DC accuracy over TL072/TL082 while maintaining full pin compatibility. Its design targets dual-supply operation (±5 V to ±15 V), with common-mode input range extending to ±11 V at ±15 V supplies and output swing within 1.1 V of rails (RL = 2 kΩ).
It features 10¹² Ω input resistance, 10 pF input capacitance, and 106 dB crosstalk attenuation between channels - confirming true dual-amplifier isolation suitable for instrumentation-grade differential signal paths without inter-channel interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard dual-rail lab and industrial power domains without level-shifting circuitry |
| Unity-Gain Bandwidth | 4.5 MHz - enables stable closed-loop gain ≥1 up to audio and ultrasonic frequencies (e.g., 20 kHz with >200× gain margin) |
| Input Offset Voltage | 0.65 mV max (25°C, ±15 V) - ensures ≤6.5 mV total error in 10× gain stages without external nulling |
| Slew Rate | 17.8 V/μs (positive), 15.9 V/μs (negative) at ±15 V - supports clean 10 Vpp output at 280 kHz without slewing distortion |
| Input Bias Current | ≤100 pA (25°C) - preserves signal integrity when interfacing with >1 MΩ source impedances (e.g., piezoelectric sensors) |
| CMRR | ≥92 dB (25°C, ±15 V) - rejects >12 V of common-mode interference while amplifying 100 mV differential signals |
| THD | 0.00021% (1 kHz, RL = 2 kΩ) - meets high-fidelity audio and metrology requirements with negligible harmonic generation |
Pinout & Package
TL052IDRE4 is supplied in an 8-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, optimized for automated PCB assembly and thermal dissipation (θJA = 97°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplified output of Channel 1 - drives loads ≥2 kΩ with rail-to-rail swing capability |
| 1IN– | Input | Inverting input of Channel 1 - accepts feedback networks for precise gain control |
| 1IN+ | Input | Non-inverting input of Channel 1 - connects to high-impedance sources without loading error |
| VCC– | Power supply | Negative supply rail - must be connected to system ground or negative voltage; no internal connection to substrate |
| 2IN+ | Input | Non-inverting input of Channel 2 - electrically isolated from Channel 1 per datasheet crosstalk spec (106 dB) |
| 2IN– | Input | Inverting input of Channel 2 - supports independent feedback configuration per channel |
| 2OUT | Output | Amplified output of Channel 2 - shares same AC/DC specs as Pin 1OUT |
| VCC+ | Power supply | Positive supply rail - requires low-ESR decoupling (0.1 μF ceramic + 10 μF tantalum) near pin |
Key Features

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 |
|---|---|---|---|
| TL072CDR | Higher input offset voltage (3.5 mV max), lower slew rate (13 V/μs), no on-chip trimming | Acceptable for non-critical AC-coupled audio; unsuitable for DC-coupled precision sensing | Select TL072CDR only when cost is primary constraint and VIO ≤3.5 mV is acceptable |
| OPA2134PA | Lower noise (8 nV/√Hz), higher CMRR (120 dB), but requires ±18 V max supply and costs ~3× more | Better for battery-powered portable instruments needing ultra-low noise; not drop-in due to different pinout | Choose OPA2134PA when THD <0.0001% and 120 dB CMRR are mandatory, and board redesign is feasible |
Compared with TL052IDRE4, TL072CDR trades precision for cost savings while retaining pin compatibility, whereas OPA2134PA delivers superior noise and CMRR at the expense of layout changes and BOM cost - making TL052IDRE4 the optimal balance for production-grade dual-channel FET op-amp needs.

FAQ
What is the maximum operating temperature range for TL052IDRE4?
The TL052IDRE4 is rated for operation from –40°C to +85°C under recommended conditions. This industrial temperature range is confirmed in Section 4.3 of the official datasheet (SLOS178B), and applies to both C-suffix (0°C to 70°C) and I-suffix (–40°C to 85°C) variants - with TL052IDRE4 being the I-suffix version. Thermal derating begins above 85°C ambient, and absolute maximum junction temperature is 150°C.
Does TL052IDRE4 support single-supply operation?
TL052IDRE4 is designed for dual-supply operation and does not support true single-supply use without external biasing. When operated from a single rail, the input common-mode range and output swing become severely limited - for example, at +10 V supply, VICR is only –1 V to +4 V and VOM+ reaches just +3 V. TI recommends using LinCMOS amplifiers (e.g., TLC-series) or adding a virtual ground (e.g., TLE2426) if single-supply functionality is required.
What is the input capacitance of TL052IDRE4 and how does it affect high-frequency stability?
The TL052IDRE4 has a typical input capacitance of 10 pF per input, as specified in Section 4.4 of the datasheet. This value directly impacts stability when driving capacitive loads: configurations with >100 pF load capacitance risk peaking or oscillation unless a series resistor (e.g., 50–100 Ω) is added at the output. The device maintains 60° phase margin only with ≤25 pF load capacitance under unity-gain conditions.
How does TL052IDRE4 compare to TL082 in terms of noise performance?
TL052IDRE4 offers significantly better noise performance than TL082: its equivalent input noise voltage is 10.8 nV/√Hz at 1 kHz versus TL082's 18 nV/√Hz, and 50 nV/√Hz at 10 Hz versus TL082's 70 nV/√Hz. This 30–40% reduction enables cleaner amplification of sub-mV signals in low-frequency applications like seismic sensors or thermocouple conditioning - a key advantage confirmed in TI's SLOS178B revision history.
Is TL052IDRE4 pin-compatible with TL072 and TL082?
Yes, TL052IDRE4 is fully pin-compatible with TL072 and TL082 in the same SOIC-8 (D) package. Pin assignments match exactly: Pin 1 (OUT A), Pin 2 (IN– A), Pin 3 (IN+ A), Pin 4 (V–), Pin 5 (IN+ B), Pin 6 (IN– B), Pin 7 (OUT B), Pin 8 (V+). This allows direct drop-in replacement in existing designs without layout changes - a core feature emphasized in TI's product description and pin configuration diagrams.
