Product details
Overview
TL052CDRE4 from Texas Instruments is a dual JFET-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 slew rate (±15 V), and 0.65 mV max input offset voltage at 25°C - enabling high-fidelity amplification of low-level sensor signals and audio waveforms in instrumentation-grade circuits.
For engineers reviewing the TL052CDRE4 datasheet, TL052CDRE4 pinout, TL052CDRE4 application, or TL052CDRE4 equivalent, this page provides verified specifications, SOIC-8 package layout, real-world use cases in sensor interfaces and active filters, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TL052CDRE4 uses enhanced JFET-input stages with on-chip offset-voltage trimming to achieve superior DC accuracy over TL072/TL082 while maintaining FET-level input impedance (>10¹² Ω) and low input bias current (≤200 pA at 25°C). Its architecture supports stable operation with capacitive loads up to 1000 pF when series output resistance is applied.
It is fully specified across ±5 V and ±15 V supplies, with common-mode input range extending to ±11 V at ±15 V supply and output swing within 1.5 V of rails (RL = 2 kΩ). The device exhibits 92 dB typical CMRR and 99 dB typical PSRR at 25°C - critical for rejecting noise in mixed-signal industrial front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard dual-rail industrial and test equipment power domains without level-shifting. |
| Unity-Gain Bandwidth | 4.5 MHz - enables stable closed-loop gain ≥10 at 450 kHz with adequate phase margin (60°). |
| Slew Rate | 17.8 V/μs (±15 V) - supports clean 10 Vpp sine output up to ~280 kHz before slew-induced distortion. |
| Input Offset Voltage | 0.65 mV max (25°C, ±15 V) - reduces DC error in precision gain stages and integrators by >50% vs TL082. |
| Input Bias Current | 200 pA max (25°C) - preserves signal integrity when interfacing with >1 MΩ source impedances (e.g., piezoelectric sensors). |
| CMRR | 92 dB typical (25°C) - rejects common-mode interference in differential sensor bridges and motor current sensing. |
| Package | SOIC-8 (D package, 4.90 mm × 3.90 mm) - surface-mount compatible with automated PCB assembly and thermal performance (θJA = 97°C/W). |
Pinout & Package
TL052CDRE4 is housed in an 8-pin SOIC (D package) with 1.27 mm pitch, 4.90 mm × 3.90 mm body size, and exposed pad not present. Pin 1 is marked via laser engraving or mold index; pin numbering follows standard IC convention (counterclockwise from top-left corner when notch faces up).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier channel 1 output - drives loads ≥2 kΩ directly; requires series resistor for >100 pF capacitive loads. |
| 1IN– | Input | Inverting input of channel 1 - high-impedance node (10¹² Ω); guard ring recommended for leakage-sensitive layouts. |
| 1IN+ | Input | Non-inverting input of channel 1 - same impedance as 1IN–; used for unity-gain buffers or differential pairs. |
| VCC– | Power | Negative supply rail - must be connected to system ground reference or negative voltage; no internal connection to substrate. |
| 2IN+ | Input | Non-inverting input of channel 2 - electrically isolated from channel 1; crosstalk attenuation ≥106 dB prevents inter-channel coupling. |
| 2IN– | Input | Inverting input of channel 2 - identical specs to 1IN–; supports independent second signal path in compact space. |
| 2OUT | Output | Amplifier channel 2 output - functionally identical to 1OUT; allows dual-path signal processing (e.g., stereo audio, dual-sensor conditioning). |
| VCC+ | Power | Positive supply rail - must be decoupled with 0.1 μF ceramic capacitor near pin; shares current limit (160 mA total per package). |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset trimming | Reduces initial VIO to ≤0.65 mV (±15 V), cutting calibration time in production test fixtures by eliminating manual nulling. |
| FET input stage | 10¹² Ω input resistance and ≤200 pA bias current enable direct interface with high-Z sources (e.g., pH electrodes, photodiode transimpedance amps). |
| Low 1/f noise | 50 nV/√Hz at 10 Hz - minimizes drift in DC-coupled sensor amplifiers where low-frequency noise dominates error budget. |
| High slew rate + low THD | 17.8 V/μs slew with 0.00021% THD at 1 kHz - preserves waveform fidelity in active filters and audio line drivers without clipping. |
| Pin-compatible upgrade | Direct replacement for TL072 and TL082 in existing SOIC-8 footprints - no PCB rework required for performance enhancement. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher 3 mV max VIO, 13 V/μs slew, 3 MHz GBW, and 18 nV/√Hz noise at 1 kHz. | Acceptable for cost-sensitive audio and general-purpose designs where <0.1% DC accuracy is not required. | Choose TL072CDR only if budget constraints outweigh need for improved offset, speed, and noise performance. |
| OPA2134PA | Lower 0.5 mV max VIO, 20 V/μs slew, 8 MHz GBW, and 8 nV/√Hz noise - but higher 4.5 mA supply current per amp. | Better suited for ultra-low-noise, wideband applications (e.g., medical EEG amplifiers) where power efficiency is secondary. | Choose OPA2134PA when system-level SNR or bandwidth demands exceed TL052CDRE4 capabilities, accepting higher quiescent power. |
Compared with TL072CDR, TL052CDRE4 offers tighter DC specs and faster dynamics at identical price and footprint; versus OPA2134PA, it trades 3.5 MHz extra bandwidth and 2 nV/√Hz lower noise for 3.3 mA lower total supply current - making it optimal for battery-aware industrial sensors and portable test gear.

FAQ
What supply voltage ranges does the TL052CDRE4 support?
The TL052CDRE4 operates across ±5 V to ±15 V dual supplies, with full electrical specifications guaranteed at both extremes. It is not rated for single-supply operation; using it with a single rail requires external DC biasing networks and virtual-ground generation (e.g., TI TLE2426) to maintain valid common-mode input and output swing.
Is the TL052CDRE4 pin-compatible with the TL072 or TL082?
Yes, the TL052CDRE4 is fully pin-compatible with TL072 and TL082 in SOIC-8 packages. Pin functions match exactly: pins 1/7 are outputs, 2/3/5/6 are inputs, and 4/8 are VCC–/VCC+. This allows drop-in replacement in existing designs to improve offset, slew rate, and noise without PCB changes.
What is the maximum capacitive load the TL052CDRE4 can drive stably?
The TL052CDRE4 is characterized with 10 pF load capacitance, but can reliably drive up to 1000 pF when a small series resistor (e.g., 10–100 Ω) is added between the output pin and the load. Without this resistor, larger capacitive loads may cause ringing or oscillation due to phase margin degradation.
How does the input offset voltage of TL052CDRE4 compare to TL082?
At ±15 V and 25°C, TL052CDRE4 has a maximum input offset voltage of 0.65 mV, versus 3 mV for TL082. This represents a >50% reduction in worst-case DC error, directly improving accuracy in precision gain stages, integrators, and sensor signal chains where offset drift contributes significantly to total error.
Does TL052CDRE4 require special PCB layout practices?
Yes - due to its ultra-low input bias current (≤200 pA), TL052CDRE4 is sensitive to board leakage. Best practice includes guard rings around both inputs (driven at common-mode voltage), clean solder mask coverage, and avoidance of conformal coating over input traces. These measures prevent surface leakage currents from dominating the FET input's bias specification.
