Product details
Overview
TL052IDG4 from Texas Instruments is a dual 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 0.65 mV max input offset voltage at 25°C. It operates from ±5 V to ±15 V supplies and targets precision analog signal conditioning in test equipment and sensor interfaces.
For engineers reviewing the TL052IDG4 datasheet, TL052IDG4 pinout, TL052IDG4 application, or TL052IDG4 equivalent, key selection criteria include its low 10 pA input bias current, 10¹² Ω input resistance, 106 dB crosstalk attenuation, and compatibility with high-impedance sources such as piezoelectric sensors and photodiode transimpedance stages.
Technical Context
The TL052IDG4 uses a JFET-input front-end architecture optimized for low input current and high DC precision, with on-die trimming to achieve sub-millivolt offset. Its internal compensation ensures stable unity-gain operation with ≤100 pF capacitive load.
It delivers improved AC performance over TL072/TL082-higher bandwidth and faster slew rate-without increasing quiescent current (8.4 mA typical at ±15 V). The device is specified across industrial temperature range (–40°C to +85°C) and supports dual-supply operation only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports standard dual-rail lab and industrial supply rails |
| Unity-Gain Bandwidth | 4.5 MHz - enables stable amplification of audio-band and low-speed control signals |
| Slew Rate | 17.8 V/μs (±15 V) - supports clean 10 kHz full-scale sine output into 2 kΩ load |
| Input Offset Voltage | 0.65 mV max (25°C, ±15 V) - reduces DC error in precision gain stages and active filters |
| Input Bias Current | 10 pA typical (25°C) - preserves signal integrity with >1 MΩ source impedances |
| Crosstalk Attenuation | 106 dB - prevents channel-to-channel interference in dual-channel instrumentation |
| Common-Mode Range | –12.3 V to +15.1 V (±15 V) - allows rail-to-rail input operation near supply extremes |
Pinout & Package
TL052IDG4 is housed in an 8-pin SOIC (D package), 4.90 mm × 3.90 mm body size, with gull-wing leads and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier A output - drives external load or feedback network |
| 1IN– | Input | Inverting input of channel A - accepts feedback or signal inversion path |
| 1IN+ | Input | Non-inverting input of channel A - connects to high-Z sensor or reference |
| VCC– | Power | Negative supply rail - must be decoupled locally with 0.1 μF ceramic |
| 2IN+ | Input | Non-inverting input of channel B - independent signal path from channel A |
| 2IN– | Input | Inverting input of channel B - supports differential or inverting configurations |
| 2OUT | Output | Amplifier B output - electrically isolated from channel A except via shared supplies |
| VCC+ | Power | Positive supply rail - requires symmetric decoupling to VCC– for noise rejection |

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 10 mV max VIO, 16 V/μs slew rate, 3 MHz GBW, no on-chip trimming | Lower precision; acceptable where calibration compensates offset | Choose TL072CDR for cost-sensitive designs where ±2 mV offset is tolerable |
| OPA2134PA | Lower 0.5 mV max VIO, 20 V/μs slew rate, 8 MHz GBW, bipolar FET hybrid input | Higher speed and lower noise; requires tighter layout for stability | Choose OPA2134PA when 80 dB SNR and <100 ns settling time are required |
Compared with TL072CDR, TL052IDG4 offers tighter offset and better AC specs; compared with OPA2134PA, it trades some bandwidth and noise performance for proven SOIC reliability and lower cost in industrial-grade applications.

FAQ
What is the maximum operating supply voltage for TL052IDG4?
The TL052IDG4 has an absolute maximum supply voltage rating of ±18 V. However, it is fully specified for reliable operation from ±5 V to ±15 V. Operating beyond ±15 V may exceed recommended conditions and impact long-term reliability or parametric guarantees defined in the datasheet. Always observe common-mode input limits relative to the chosen supply rails when using TL052IDG4.
Does TL052IDG4 support single-supply operation?
No, TL052IDG4 is designed exclusively for dual-supply operation. Its input common-mode range and output swing are specified only for symmetric ±VCC configurations. Attempting single-supply use without proper DC biasing violates the recommended operating conditions and risks saturation, distortion, or undefined behavior. For single-supply applications, TI recommends LinCMOS families like TLC27L2 instead of TL052IDG4.
What is the input bias current specification of TL052IDG4 at 85°C?
At 85°C, the TL052IDG4 exhibits a maximum input bias current of 0.7 nA under ±15 V supply conditions, as confirmed in Section 4.5 of the datasheet. This value reflects worst-case leakage across process and temperature extremes. At room temperature (25°C), the typical input bias current is 30 pA, making TL052IDG4 suitable for ultra-high-impedance nodes where thermal drift must remain bounded.
Can TL052IDG4 drive a 1000 pF capacitive load directly?
TL052IDG4 is not guaranteed to remain stable with 1000 pF capacitive loads without external series resistance. The datasheet specifies stable unity-gain operation up to 100 pF. For larger loads, a small resistor (e.g., 20–100 Ω) must be added in series with the output to isolate the amplifier from the capacitive reactance. This technique restores phase margin and prevents ringing or oscillation in circuits using TL052IDG4.
How does TL052IDG4 differ from TL052CP?
TL052IDG4 is the industrial-grade (–40°C to +85°C) version in SOIC packaging, while TL052CP is the commercial-grade (0°C to +70°C) version in PDIP packaging. Both share identical electrical specifications, pinout, and functionality-but TL052IDG4 undergoes extended temperature screening and is qualified for harsher environments. The 'I' suffix denotes industrial temperature grade, and 'DG4' specifies SOIC-8 with green (lead-free) finish, whereas 'CP' indicates PDIP-8 with legacy finish.
