Product details
Overview
TLE2061IDRG4 from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for high-voltage (±18 V), low-power (120 μA typical supply current), and high-output-drive applications. It delivers 1.1 MHz gain-bandwidth, 2.2 V/μs slew rate at ±5 V, and specified output drive into 100 Ω loads - enabling precision signal conditioning in engine control analog front-ends and flight control sensor interfaces.
For engineers reviewing the TLE2061IDRG4 datasheet, TLE2061IDRG4 pinout, TLE2061IDRG4 application, or TLE2061IDRG4 equivalent, this page provides verified package mapping (SOIC-8), confirmed DC/AC performance specs across temperature ranges (–40°C to +85°C), real-world application context for aerospace and industrial analog modules, and validated alternative options with documented functional trade-offs.
Technical Context
The TLE2061IDRG4 uses a JFET-input stage with on-chip Zener trimming for offset voltage stability, supporting rail-to-rail input common-mode range (–11 V to +13 V at ±15 V supplies) and delivering >225 V/mV large-signal open-loop gain. Its 6 || 1 TΩ || pF common-mode input impedance and 540 GΩ || 3 pF differential impedance preserve signal integrity in high-impedance sensor interfaces.
It operates across ±3.5 V to ±18 V supplies with 75–135 dB supply-voltage rejection and 65–90 dB common-mode rejection. Phase margin is 46° at unity gain (RL = 10 kΩ, CL = 100 pF), ensuring stable closed-loop operation without external compensation in standard configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±3.5 V to ±18 V - supports dual-rail industrial and avionics power domains without level-shifting. |
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain buffering and closed-loop amplification up to ~140 kHz with full output swing. |
| Input Offset Voltage (max) | 3.1 mV at 25°C (TLE2061I grade) - ensures ≤±3.1 mV DC error in precision transducer signal chains. |
| Slew Rate | 2.2 V/μs at ±5 V (25°C) - sustains clean 10 kHz sine-wave output with <0.025% THD into 10 kΩ. |
| Supply Current (typ) | 120 μA per channel - enables battery-operated or energy-constrained analog modules with minimal thermal load. |
| Output Drive Capability | Specified into 100 Ω loads - directly drives low-impedance DAC buffers, line drivers, or actuator interfaces without external boost stages. |
| Input Bias Current (max) | 4 nA over –40°C to +85°C - preserves accuracy in high-Z pH sensors, photodiode amps, or piezoelectric charge amplifiers. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6 mm body, gull-wing leads, RoHS-compliant, tape-and-reel (R suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (NC on TLE2061I) | No connection - unused in I-grade variant; internal offset trim is factory-set and not user-adjustable. |
| 2 | Inverting Input (IN–) | High-impedance JFET node (6 TΩ || 1 pF) - accepts feedback networks without loading error. |
| 3 | Non-Inverting Input (IN+) | High-impedance JFET node - supports direct connection to high-Z sensors or reference dividers. |
| 4 | VCC– (Negative Supply) | Ground-referenced negative rail - must be decoupled locally with ≥0.1 μF ceramic capacitor. |
| 5 | Offset Null (NC on TLE2061I) | No connection - matches pinout compatibility with C/A-grade variants but functionally inactive. |
| 6 | Output (OUT) | Class-AB output stage capable of ±12.5 V swing into 600 Ω - drives low-Z loads without external buffer. |
| 7 | VCC+ (Positive Supply) | Ground-referenced positive rail - requires local 0.1 μF ceramic decoupling adjacent to pin. |
| 8 | NC | No internal connection - electrically isolated; no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables ≤4 nA max input bias current over –40°C to +85°C, critical for high-impedance sensor interfacing. |
| High-output-drive capability | Guaranteed performance into 100 Ω loads - eliminates need for external driver stages in actuator control loops. |
| Low 1/f noise corner | 1.1 µV peak-to-peak (0.1–10 Hz) - maintains signal fidelity in DC-coupled precision measurement paths. |
| Wide supply range | Operates from ±3.5 V to ±18 V - accommodates legacy ±15 V systems and modern low-voltage industrial rails. |
| Zener-trimmed offset | Factory-trimmed VIO ≤3.1 mV (TLE2061I) - reduces calibration overhead in production test and field deployment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061CDR | Same SOIC-8 package and pinout; C-grade (0°C to 70°C) with 3 mV max VIO vs. I-grade's 3.1 mV. | Limited to commercial-temperature environments; unsuitable for under-hood or avionics use. | Select when operating ambient stays within 0–70°C and cost sensitivity outweighs extended temperature coverage. |
| TL071CP | SOIC-8, JFET-input, but higher 250 μA supply current and 16 V max supply (vs. ±18 V); no guaranteed 100 Ω drive spec. | Lower drive strength and narrower supply range reduce suitability for demanding industrial actuators or legacy ±15 V systems. | Acceptable for general-purpose lab-grade amplification where power and output swing margins are less critical. |
Compared with TLE2061IDRG4, TLE2061CDR sacrifices temperature range for lower cost in benign environments, while TL071CP trades supply headroom and output drive for broader distributor availability - neither offers the same combination of I-grade reliability, 100 Ω load support, and ±18 V operation.

FAQ
What is the maximum operating temperature range for the TLE2061IDRG4?
The TLE2061IDRG4 is rated for operation from –40°C to +85°C (I-grade). This extended industrial temperature range is validated per TI's SLOS193D datasheet Section 5.2 and supports deployment in engine compartments, avionics bays, and factory-floor control cabinets without derating.
Does the TLE2061IDRG4 require external offset nulling components?
No. The TLE2061IDRG4 uses factory Zener-trimmed offset voltage and has NC (no connect) pins 1 and 5 - unlike earlier C/A-grade variants. Its input offset is fixed at ≤3.1 mV (max) across temperature, eliminating need for external trimpots or nulling circuitry in production designs.
Can the TLE2061IDRG4 drive a 100 Ω load reliably?
Yes. The TLE2061IDRG4 is explicitly characterized for operation into 100 Ω loads per its datasheet Features section and Section 5.11 (M-grade) and 5.7 (I-grade) electrical characteristics. At ±15 V supplies, it delivers ≥±12.5 V swing into 600 Ω and maintains stability and THD performance under these conditions.
What is the input bias current specification for TLE2061IDRG4 over temperature?
The TLE2061IDRG4 exhibits ≤4 nA maximum input bias current across its full –40°C to +85°C operating range (Section 5.7, TLE2061I Electrical Characteristics). This ultra-low IB enables accurate amplification of signals from high-impedance sources like piezoelectric sensors or pH electrodes without significant DC error.
Is the TLE2061IDRG4 pin-compatible with other TLE206x variants in SOIC-8?
Yes. All TLE2061x variants in SOIC-8 (D package), including TLE2061CDR, TLE2061ACDR, and TLE2061IDRG4, share identical pinout per Figure 4-2 of the datasheet. Pins 1 and 5 are NC across all grades in D-package, ensuring drop-in replacement for layout reuse - though temperature grade and VIO specs differ.
