Product details
Overview
TL052IDR 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 10¹² Ω input resistance-designed for precision analog signal conditioning in audio preamplifiers, sensor interfaces, and instrumentation circuits.
For engineers reviewing the TL052IDR datasheet, TL052IDR pinout, TL052IDR application, or TL052IDR equivalent, key selection criteria include its enhanced DC accuracy over TL072/TL082, FET-input high-impedance interface capability, dual-supply operation (±5 V to ±15 V), and SOIC-8 package compatibility with legacy designs.
Technical Context
The TL052IDR uses a JFET-input front-end architecture to achieve ultra-low input bias current (10 pA typ at 25°C) and high input impedance, enabling accurate amplification of signals from high-impedance sources like piezoelectric sensors and photodiode transimpedance stages. Its trimmed offset voltage (0.65 mV max at ±15 V, 25°C) and low temperature drift (23 μV/°C) support stable DC-coupled measurement paths.
It delivers improved AC performance versus TL082-4.5 MHz bandwidth and 17.8 V/μs slew rate at ±15 V-without increasing quiescent current (8.4 mA typ), making it suitable for wide-dynamic-range, low-noise signal chains where both precision and speed are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 0.65 mV max (±15 V, 25°C): enables sub-millivolt DC accuracy in closed-loop gain ≥100 without external nulling. |
| Unity-Gain Bandwidth | 4.5 MHz: supports stable amplification of audio-band and medium-speed sensor signals up to ~2 MHz with minimal phase lag. |
| Slew Rate | 17.8 V/μs (±15 V): allows full-scale 10 Vpp output at 280 kHz without distortion in unity-gain follower configuration. |
| Input Resistance | 10¹² Ω: prevents loading of high-Z sources such as electret microphones, pH electrodes, or capacitive touch sensors. |
| Input Noise Voltage | 10.8 nV/√Hz @ 1 kHz: ensures low-noise amplification in sensitive front-ends where source impedance exceeds 50 kΩ. |
| Common-Mode Range | –11 V to +11 V (±15 V supply): permits rail-to-rail input operation within 4 V of each supply, simplifying level-shifting in dual-supply systems. |
| Supply Current | 8.4 mA typ (±15 V, 25°C): maintains low power in dual-channel precision applications without thermal derating concerns. |
Pinout & Package
TL052IDR 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. It is RoHS-compliant and rated for industrial temperature range (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier A output; drives loads ≥2 kΩ with ±11.5 V swing (±15 V supply) and 80 mA short-circuit capability. |
| 1IN– | Input | Inverting input of Amplifier A; high-impedance node requiring guard ring layout to minimize leakage-induced offset drift. |
| 1IN+ | Input | Non-inverting input of Amplifier A; accepts common-mode voltages from –11 V to +11 V under ±15 V supply. |
| VCC– | Power | Negative supply rail; must be decoupled with 0.1 μF ceramic capacitor placed ≤5 mm from pin. |
| 2IN+ | Input | Non-inverting input of Amplifier B; electrically isolated from Channel A-crosstalk attenuation is 106 dB. |
| 2IN– | Input | Inverting input of Amplifier B; shares same FET-input characteristics and noise performance as Channel A inputs. |
| 2OUT | Output | Amplifier B output; independently buffered and capable of driving identical loads as 1OUT. |
| VCC+ | Power | Positive supply rail; requires local 0.1 μF ceramic bypass and optional bulk capacitance for transient load stability. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip offset-voltage trimming | Reduces initial VIO to ≤0.65 mV (±15 V), eliminating manual nulling circuitry and improving production test yield. |
| JFET-input architecture | Delivers 10 pA typical input bias current at 25°C-critical for integrating low-leakage photodiode or piezoelectric sensor signals. |
| Enhanced slew rate vs TL082 | 17.8 V/μs (±15 V) enables faster settling in active filters and peak detectors without sacrificing power efficiency. |
| High CMRR and PSRR | 92 dB CMRR and 99 dB PSRR at 25°C suppress interference from noisy power rails and common-mode pickup in PCB layouts. |
| Pin-compatible upgrade path | Direct replacement for TL072 and TL082 in SOIC-8 footprints-no PCB revision required for performance enhancement. |

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 mV max), lower slew rate (13 V/μs), higher input noise (18 nV/√Hz @ 1 kHz) | Acceptable where cost sensitivity outweighs precision and speed requirements | Choose TL072CDR only if design tolerates higher DC error and slower transient response. |
| OPA2134UA | Lower noise (8 nV/√Hz), lower VIO (0.5 mV max), higher GBW (8 MHz), but higher supply current (4 mA per amp) | Better suited for ultra-low-noise audio or medical-grade signal chains with tighter power budgets | Prefer OPA2134UA when 2× noise reduction and 1.8× bandwidth justify 2× quiescent current increase. |
Compared with TL072CDR, TL052IDR offers superior DC accuracy and speed at identical package and pinout; compared with OPA2134UA, it trades some noise and bandwidth for lower cost and proven industrial reliability in long-lifecycle instrumentation.

FAQ
What is the maximum supply voltage rating for TL052IDR?
The absolute maximum supply voltage for TL052IDR is ±18 V. Operation beyond this limit risks permanent damage. The device is fully specified across ±5 V to ±15 V recommended ranges, with electrical characteristics guaranteed at both extremes. At ±15 V, TL052IDR delivers 17.8 V/μs slew rate and 4.5 MHz unity-gain bandwidth while drawing 8.4 mA typical supply current.
Does TL052IDR support single-supply operation?
TL052IDR is designed for dual-supply operation and does not feature rail-to-rail input or output. When used with single supplies, external DC biasing of inputs and mid-supply virtual ground generation (e.g., using TLE2426) are mandatory to keep inputs within the common-mode range (–11 V to +11 V at ±15 V). Without proper biasing, the device may saturate or malfunction.
How does TL052IDR differ from TL082 in practical circuit design?
TL052IDR improves upon TL082 with on-chip offset trimming (0.65 mV vs 3 mV max), higher slew rate (17.8 V/μs vs 13 V/μs), lower input noise (10.8 nV/√Hz vs 18 nV/√Hz), and better CMRR (92 dB vs 80 dB). These differences reduce need for external nulling, improve fidelity in audio and fast-sensing applications, and enhance rejection of power-supply noise-making TL052IDR a direct, no-layout-change upgrade.
What is the input bias current specification for TL052IDR at 85°C?
At 85°C, TL052IDR exhibits a maximum input bias current of 0.7 nA (700 pA) under ±15 V supply conditions. This value reflects the JFET-input structure's inherent thermal stability-significantly lower than bipolar-input op-amps-and ensures reliable operation in high-temperature industrial environments without signal degradation from input leakage.
Can unused channels in TL052IDR be left floating?
No. Unused op-amp channels in TL052IDR must be configured as unity-gain buffers with inputs tied to a valid common-mode voltage (e.g., mid-supply via resistive divider) to prevent oscillation or excessive current draw. Leaving inputs unconnected violates the absolute maximum rating for input voltage and may cause unpredictable output behavior or increased supply current.
