Product details
Overview
TL052AIDRG4 from Texas Instruments is a dual enhanced 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 operates from ±5 V to ±15 V supplies and targets precision analog signal conditioning in audio preamps, sensor interfaces, and instrumentation circuits.
For engineers reviewing the TL052AIDRG4 datasheet, TL052AIDRG4 pinout, TL052AIDRG4 application, or TL052AIDRG4 equivalent, this page delivers verified specifications, SOIC-8 package layout, real-world use cases, and validated alternative options - all grounded in TI's SLOS178B production data sheet (Jan 2026 revision).
Technical Context
The TL052AIDRG4 implements a dual-channel FET-input architecture with independent high-impedance inputs (10¹² Ω), low input bias current (≤30 pA at 25°C), and rail-to-rail output swing limited by supply headroom (e.g., ±13.9 V at ±15 V with 10 kΩ load). Its internal offset trimming enables stable DC performance across temperature.
It maintains pin compatibility with TL072 and TL082 but improves slew rate (+25% vs TL082), reduces input offset voltage (−40% vs TL082A), and retains low 10.8 nV/√Hz input voltage noise at 1 kHz - making it suitable for medium-speed, low-noise, high-Z signal chains where bipolar op-amps introduce excessive input current error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports industrial dual-supply systems without level-shifting circuitry |
| Input Offset Voltage (max) | 0.8 mV at 25°C (TL052AC grade) - enables <1 LSB error in 12-bit ADC front-ends with gain ≤10 |
| Unity-Gain Bandwidth | 4.5 MHz - sufficient for audio band amplification (20 Hz–20 kHz) with >60° phase margin |
| Slew Rate (±15 V) | 17.8 V/μs - supports 10 Vpp signals up to ~280 kHz without slew-induced distortion |
| Input Bias Current (max) | 0.2 nA at 70°C - preserves accuracy with >1 MΩ source impedances (e.g., piezoelectric sensors) |
| CMRR (min) | 75 dB at 25°C - rejects common-mode interference in differential sensor bridges |
| THD + N | 0.00021% at 1 kHz - meets high-fidelity audio signal path requirements |
Pinout & Package
TL052AIDRG4 is housed in an 8-pin SOIC (D package), 4.90 mm × 3.90 mm body size, with exposed pad not present and moisture sensitivity level (MSL) 1 per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output Channel 1 | Low-impedance buffered output; drives loads ≥2 kΩ without stability issues |
| 2 | Inverting Input, Ch. 1 | High-Z node (10¹² Ω); requires guard ring routing to minimize PCB leakage error |
| 3 | Non-inverting Input, Ch. 1 | High-Z node; matched to Pin 2 for optimal CMRR in differential configurations |
| 4 | Power Supply Negative | Return path for both channels; must be low-inductance connection to avoid crosstalk |
| 5 | Non-inverting Input, Ch. 2 | Independent high-Z input; electrically isolated from Ch. 1 except via shared VCC– |
| 6 | Inverting Input, Ch. 2 | Matched pair with Pin 5; enables dual-channel instrumentation or active filtering |
| 7 | Output Channel 2 | Independent output; crosstalk attenuation ≥106 dB prevents inter-channel signal coupling |
| 8 | Power Supply Positive | Supply rail for both amplifiers; decoupling capacitor (0.1 μF) required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤0.57 mV (25°C), cutting calibration time in production test fixtures |
| FET-input architecture | 10¹² Ω input resistance enables direct interfacing with pH electrodes and photodiode transimpedance stages |
| Enhanced slew rate vs TL082 | 17.8 V/μs (±15 V) supports faster settling in active filters and anti-aliasing stages than TL082's 13 V/μs |
| Low 1/f noise corner | 50 nV/√Hz at 10 Hz allows stable DC-coupled amplification of microvolt-level bio-sensor outputs |
| Pin-compatible upgrade path | Direct replacement for TL072/TL082 in existing SOIC-8 layouts - no PCB rework required |

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 3 mV max VIO, lower 13 V/μs slew rate, 16 V/μs typical noise (10 Hz) | Acceptable for cost-sensitive audio where <0.5 mV VIO not required | Choose TL072CDR only if offset and speed margins allow relaxed spec compliance |
| OPA2134PA | Lower 0.5 mV max VIO, higher 20 V/μs slew rate, 8 nV/√Hz noise, ±18 V rating | Preferred for high-end audio or wide-supply industrial systems needing extended dynamic range | OPA2134PA offers superior specs but requires validation of SOIC-8 thermal derating at full load |
Compared with TL052AIDRG4, TL072CDR trades precision and speed for lower cost, while OPA2134PA delivers higher performance at increased price and power - making TL052AIDRG4 the optimal balance for mid-tier instrumentation requiring verified offset stability and SOIC-8 footprint compatibility.

FAQ
What is the maximum operating temperature range for TL052AIDRG4?
The TL052AIDRG4 is specified for operation from 0°C to 70°C (commercial grade, C-suffix). It is not rated for extended industrial temperature ranges (–40°C to 85°C); for that, the TL052AI variant must be selected. Thermal derating begins above 70°C, and junction temperature must remain below 150°C under all conditions per absolute maximum ratings.
Does TL052AIDRG4 support single-supply operation?
TL052AIDRG4 is designed for dual-supply operation (±5 V to ±15 V) and does not feature rail-to-rail input or output. When used with single supplies, external DC biasing of inputs and virtual-ground generation (e.g., using TI's TLE2426) is mandatory to stay within common-mode input voltage limits (e.g., –1 V to +4 V at ±5 V supply) and avoid clipping.
What is the input capacitance of TL052AIDRG4 and how does it affect high-frequency stability?
TL052AIDRG4 has a typical input capacitance of 10 pF per input terminal. This value interacts with source impedance to form unintended poles; for example, with a 100 kΩ source, a pole appears at ~160 kHz. Layout best practices - including short traces, guard rings, and avoiding floating nodes - are essential to prevent oscillation in high-Z sensor interfaces.
Can TL052AIDRG4 drive capacitive loads directly?
TL052AIDRG4 can drive ≤100 pF loads stably without external compensation. For larger capacitive loads (e.g., 1000 pF), a series isolation resistor (typically 20–100 Ω) between the output and load is required to maintain ≥60° phase margin and prevent peaking or oscillation, as confirmed in TI's Figure 5-2 test circuit and SLOS178B Section 5.1.1.
How does the crosstalk attenuation of TL052AIDRG4 impact dual-channel designs?
TL052AIDRG4 provides ≥106 dB crosstalk attenuation between channels, meaning a 1 V signal on Channel 1 induces less than 0.5 μV of coupled signal on Channel 2. This enables independent simultaneous use - such as stereo audio paths or dual-sensor readouts - without measurable inter-channel interference in PCB layouts with proper grounding and supply decoupling.
