Product details
Overview
TLE2061ID from Texas Instruments is a single-channel, JFET-input operational amplifier with 1.1 MHz gain-bandwidth product, 120 μA supply current (typical), ±18 V max supply voltage, and high-output-drive capability into 100 Ω loads. It delivers precision DC performance and low-noise AC operation for analog signal conditioning in aerospace and industrial control systems.
For engineers reviewing the TLE2061ID datasheet, TLE2061ID pinout, TLE2061ID application, or TLE2061ID equivalent, this device is selected for high-voltage, low-power, FET-input amplifier roles where input bias current <10 pA, CMRR ≥72 dB, and stable operation over –40°C to +85°C are required.
Technical Context
The TLE2061ID uses JFET-input transistors with on-chip Zener trimming for offset voltage control, enabling low input bias current (±3 pA typical) and high input impedance (1 TΩ). Its architecture supports rail-to-rail output swing into high-impedance loads and maintains phase margin ≥46° at unity gain with 10 kΩ load and 100 pF capacitance.
It operates across ±3.5 V to ±18 V supplies and features a common-mode input range extending to within 1.6 V of rails at ±5 V supply - critical for wide-dynamic-range sensor interfacing. The device is specified for industrial temperature range (–40°C to +85°C) and exhibits 1 μV/°C input offset drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain buffering and closed-loop bandwidth up to ~140 kHz at full output swing. |
| Supply Current | 120 μA (typ) - supports battery-powered or energy-constrained systems without sacrificing drive strength. |
| Input Bias Current | ±3 pA (typ) - preserves signal integrity in high-impedance sensor front-ends (e.g., piezoelectric, photodiode). |
| Common-Mode Rejection Ratio | 72 dB (min) - rejects noise coupled onto differential sensor lines in noisy industrial environments. |
| Output Drive | Specified into 100 Ω - delivers >±2 V swing at 100 Ω load, supporting direct interface to ADC drivers or line drivers. |
| Input Offset Voltage | 3 mV (max, –40°C to +85°C) - ensures sub-mV-level accuracy in precision instrumentation amplifiers. |
| Slew Rate | 2.6 V/μs (±15 V supply) - supports fast settling (<10 μs to 0.01%) for multiplexed data acquisition systems. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6 mm body, surface-mount, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (NC on TLE2061ID) | No connection - internal offset trim not accessible; pin left unconnected per datasheet. |
| 2 | Inverting Input (IN–) | Differential input node; high-impedance JFET gate structure minimizes loading on feedback networks. |
| 3 | Non-Inverting Input (IN+) | High-Z input node; common-mode range extends to within 1.6 V of rails at ±5 V supply. |
| 4 | VCC– (Negative Supply) | Ground reference for dual-supply operation; supports true bipolar signal handling down to –18 V. |
| 5 | Offset Null (NC on TLE2061ID) | No connection - unused; no external trim required due to factory Zener-trimmed offset. |
| 6 | Output (OUT) | Class-AB output stage capable of sourcing/sinking >10 mA into 100 Ω while maintaining linearity. |
| 7 | VCC+ (Positive Supply) | Supports up to +18 V; enables operation with standard ±15 V industrial rails or asymmetric supplies. |
| 8 | NC | No internal connection - electrically isolated; must be left floating or grounded per layout best practices. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables <10 pA input bias current - essential for integrating capacitive sensors or high-R feedback networks. |
| High-output-drive specification | Guaranteed performance into 100 Ω loads - eliminates need for external buffer stages in line-driver applications. |
| Zener-trimmed input offset | Reduces VIO to ≤3 mV over –40°C to +85°C - lowers calibration burden in production test. |
| Low 1/f noise corner | 10 Hz corner frequency with 59 nV/√Hz @ 10 Hz - improves resolution in DC-coupled precision measurement paths. |
| Wide supply range | ±3.5 V to ±18 V operation - supports legacy ±15 V systems and modern low-voltage industrial designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061CD | Same silicon, commercial temperature range (0°C to 70°C); 500 μV max VIO (25°C) vs. 3 mV (TLE2061ID over full range). | Not qualified for industrial ambient; unsuitable for outdoor or engine bay deployments. | Select when cost sensitivity outweighs extended temperature requirement and system calibration accommodates higher VIO drift. |
| TL071CP | Higher supply current (1.4 mA), lower GBW (3 MHz), no Zener trimming - VIO max 10 mV over 0°C to 70°C. | Lacks industrial temp rating and low-IIB spec; not suitable for high-Z sensor interfaces. | Choose only for non-critical, low-cost consumer-grade signal buffering where power and precision are secondary. |
Compared with TLE2061CD and TL071CP, the TLE2061ID provides guaranteed industrial-temperature performance, factory-trimmed offset, and ultra-low input bias current - making it the sole option among the three for high-reliability, low-drift analog signal chains in embedded control.

FAQ
What is the maximum supply voltage for the TLE2061ID?
The TLE2061ID supports a maximum supply voltage of ±18 V (36 V total), with recommended operation between ±3.5 V and ±18 V. Absolute maximum ratings specify VCC+ − VCC− ≤ 38 V, but sustained operation above ±18 V risks parametric degradation and reduced reliability. This rating enables compatibility with standard industrial ±15 V rails and legacy avionics power systems.
Does the TLE2061ID require external offset nulling?
No, the TLE2061ID does not require external offset nulling. It uses on-chip Zener trimming to achieve factory-set input offset voltage ≤3 mV over –40°C to +85°C. Pins 1 and 5 are designated NC (no connection) in the SOIC-8 package and must remain unconnected. External trimming would disrupt the calibrated offset and is neither supported nor recommended for the TLE2061ID.
What is the input bias current specification for the TLE2061ID?
The TLE2061ID has a typical input bias current of ±3 pA at 25°C, with a maximum of 30 nA over the full industrial temperature range (–40°C to +85°C). This ultra-low value stems from its JFET-input architecture and makes the TLE2061ID suitable for high-impedance sensor interfaces, such as piezoelectric accelerometers and pH electrodes, where leakage-induced errors must be minimized.
Can the TLE2061ID drive a 100 Ω load effectively?
Yes, the TLE2061ID is explicitly specified for high-output-drive performance into 100 Ω loads. At ±15 V supply, it delivers ≥±12.5 V output swing into 600 Ω and maintains usable linearity into 100 Ω - enabling direct interface to coaxial cables, line receivers, or ADC driver stages without external buffers. This capability is confirmed in Section 5.5 and 5.9 of the TLE2061ID datasheet.
How does the TLE2061ID compare to the TL071 in terms of precision and temperature range?
The TLE2061ID offers superior precision and broader temperature qualification versus the TL071: it guarantees ≤3 mV input offset over –40°C to +85°C (vs. TL071's 10 mV over 0°C to 70°C), draws 120 μA vs. 1.4 mA supply current, and achieves 1 μV/°C offset drift (vs. TL071's unspecified drift). The TLE2061ID is rated for industrial use; the TL071 is commercial-grade only.
