Product details
Overview
TLE2072AIDG4 from Texas Instruments is a dual-channel, JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±3.5 mV max input offset voltage (25°C), 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, and 17 nV/√Hz input voltage noise at 1 kHz - enabling accurate signal conditioning in oscilloscopes, electricity meters, and AC drive power stage modules.
For engineers reviewing the TLE2072AIDG4 datasheet, TLE2072AIDG4 pinout, TLE2072AIDG4 application, or TLE2072AIDG4 equivalent, this device supports rail-to-rail input operation up to ±19 V supplies, features low bias current (±15 pA typ), and maintains stability in unity-gain configurations - critical for data acquisition front-ends and portable test equipment design.
Technical Context
The TLE2072AIDG4 employs Excalibur JFET-input architecture with on-chip Zener trimming for enhanced DC precision. Its wide supply range (±2.25 V to ±19 V) and differential input capability up to the rails support high-dynamic-range analog signal paths in industrial and instrumentation systems.
It achieves 56° phase margin at unity gain with 25 pF capacitive load and exhibits low distortion (0.0032% THD+N at 1 kHz), making it suitable for closed-loop precision amplification and active filtering without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables matched-pair signal processing in differential receivers or dual-stage amplifiers without inter-device mismatch concerns. |
| Unity-Gain Bandwidth | 10.6 MHz - supports stable unity-gain configurations for buffer, follower, or active filter applications up to ~10 MHz. |
| Slew Rate | 32 V/μs - ensures faithful reproduction of fast transients (e.g., pulse edges in DMM sampling or motor current sensing). |
| Input Voltage Noise | 17 nV/√Hz @ 1 kHz - minimizes added noise in low-level sensor signal amplification (e.g., shunt-based current measurement). |
| Input Bias Current | ±15 pA (typ) - preserves accuracy in high-impedance source interfaces such as piezoelectric sensors or photodiode transimpedance stages. |
| Supply Voltage Range | ±2.25 V to ±19 V - accommodates wide-swing industrial supplies and enables direct interfacing with ±15 V legacy systems. |
| Offset Voltage (max) | ±3.5 mV @ 25°C - guarantees initial DC accuracy without trimming in cost-sensitive metering and control loops. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6.0 mm body, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance JFET node accepting negative feedback signals; supports rail-to-rail common-mode input down to V– – 0.8 V. |
| 2 | Non-Inverting Input (Channel 1) | High-impedance JFET node for reference or signal injection; common-mode range extends to V+ + 0.5 V. |
| 3 | Output (Channel 1) | Capable of ±20 mA continuous output drive; swings within 1.5 V of rails at full load (±15 V supply). |
| 4 | V– (Negative Supply) | Reference for internal biasing; must be connected to system ground or negative rail - no internal connection to substrate. |
| 5 | Non-Inverting Input (Channel 2) | Independent high-Z input identical to Pin 2; enables dual-channel operation without crosstalk in shared-supply designs. |
| 6 | Inverting Input (Channel 2) | Independent high-Z input identical to Pin 1; supports separate feedback networks per channel. |
| 7 | Output (Channel 2) | Matched performance to Pin 3; allows independent loading and routing for dual-path signal chains. |
| 8 | V+ (Positive Supply) | Power rail connection; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability at full bandwidth. |
Key Features
| Feature | Design Value |
|---|---|
| Low input voltage noise | 17 nV/√Hz at 1 kHz - reduces integrated noise floor in 10 Hz–100 kHz bandwidths typical of energy metering and audio preamps. |
| Rail-to-rail input capability | Operates with inputs up to V– – 0.8 V and V+ + 0.5 V - eliminates level-shifting circuitry when interfacing with unipolar sensors or DACs. |
| Unity-gain stable | No external compensation required - simplifies PCB layout and reduces BOM count in buffer and gain-of-one configurations. |
| Wide supply range | ±2.25 V to ±19 V - supports both low-power portable instruments and high-voltage industrial control signal conditioning. |
| Low input bias current | ±15 pA typical - prevents significant voltage drop across >1 MΩ source impedances, preserving gain accuracy in high-Z transducer interfaces. |
Applications
| Electricity Meter Front-End | Oscilloscope Vertical Amplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher input offset (±6 mV max), higher noise (18 nV/√Hz), same SOIC-8 package. | Limited to lower-precision instrumentation; not recommended for Class 0.2 metering or sub-μs settling requirements. | Select when cost sensitivity outweighs noise/accuracy needs and ±19 V supply is not required. |
| OPA2134PA | Lower noise (8 nV/√Hz), lower offset (±500 µV max), but narrower supply (±18 V max) and higher quiescent current (4 mA/ch). | Better for ultra-low-noise audio; less suitable for battery-powered DMMs due to higher ICC. | Prefer for audio-grade signal chains where 17 nV/√Hz is insufficient, accepting higher power and cost. |
Compared with TL072CDR and OPA2134PA, the TLE2072AIDG4 uniquely balances ±3.5 mV offset, 17 nV/√Hz noise, 32 V/μs slew rate, and ±19 V operation in SOIC-8 - making it optimal for industrial metering and high-dv/dt monitoring where supply headroom and transient fidelity are critical.

FAQ
What is the maximum supply voltage rating for the TLE2072AIDG4?
The TLE2072AIDG4 supports a total supply voltage (V+ to V−) up to 38 V, corresponding to ±19 V operation. Absolute maximum ratings specify 0 V to 38 V across the supply pins, with recommended operating range from ±2.25 V to ±19 V per the datasheet's Section 6.2. Exceeding ±19 V risks exceeding absolute maximum junction temperature limits under load.
Does the TLE2072AIDG4 require external compensation for unity-gain stability?
No, the TLE2072AIDG4 is internally compensated and unity-gain stable. Its phase margin remains ≥56° at unity gain with 25 pF capacitive load and 2 kΩ source resistance, as verified in Section 6.4 and 6.10 of the datasheet. No external compensation network is needed for gain ≥1 configurations.
What is the input bias current specification for the TLE2072AIDG4 at 85°C?
At TA = 85°C, the TLE2072AIDG4 (I-suffix grade) specifies a maximum input bias current of ±10 nA, per Section 6.7 and 6.9 of the datasheet. This is derived from the TLE2072AI electrical characteristics table, where full-range (−40°C to 85°C) IIB is rated at 10 nA max - critical for high-impedance sensor interfaces in automotive or industrial environments.
Can the TLE2072AIDG4 drive a 600 Ω load effectively?
Yes, the TLE2072AIDG4 delivers ±65 mA short-circuit output current and maintains >90 dB large-signal voltage gain into 600 Ω loads at ±15 V supply (Section 6.5). Its output swing remains within 1.5 V of rails at ±20 mA, supporting full-scale 3 VPP signals into 600 Ω - suitable for driving legacy test equipment inputs and line drivers.
How does the TLE2072AIDG4 differ from the standard TLE2072IDR?
The TLE2072AIDG4 is the A-grade (improved offset) version in SOIC-8 packaging, with ±3.5 mV max input offset voltage at 25°C versus ±6 mV for the standard TLE2072IDR. Both share identical pinout, bandwidth, noise, and supply specs, but the "A" suffix denotes tighter DC precision - essential for applications demanding initial accuracy without trimming, such as revenue-grade metering.
