Product details
Overview
TLE2061ACD from Texas Instruments is a single-channel FET-input operational amplifier optimized for high-voltage, low-power precision signal conditioning in industrial and aerospace systems. It delivers 1.1 MHz gain-bandwidth, 120 μA supply current (typ), ±18 V max supply range, and specified output drive into 100 Ω loads - enabling use in analog input modules and flight control unit sensor interfaces.
For engineers reviewing the TLE2061ACD datasheet, TLE2061ACD pinout, TLE2061ACD application, or TLE2061ACD equivalent, this page provides verified package mapping (SOIC-8), confirmed DC/AC performance specs at 25°C and full temperature range, real-world output swing data into 100 Ω, and validated alternatives for design continuity.
Technical Context
The TLE2061ACD uses JFET-input transistors with on-chip Zener trimming for offset voltage stability, supporting rail-to-rail input common-mode range up to ±13 V at ±15 V supplies. Its 4 V/µs slew rate and 46° phase margin ensure stable unity-gain operation with capacitive loads up to 100 pF.
Designed for high-output-drive applications, it maintains specified performance into 100 Ω loads - unlike standard micropower op-amps - while retaining ultra-low input bias current (±10 pA typ) and 6–10 pF input capacitance, making it suitable for high-impedance sensor buffering and precision integrators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain. |
| Supply Current | 120 μA typical - supports battery-powered or energy-constrained systems without sacrificing bandwidth. |
| Input Offset Voltage | 2.6 mV max at 25°C - ensures <0.5% error in 12-bit ADC front-end applications with ±5 V reference. |
| Output Drive Capability | Specified into 100 Ω load - allows direct driving of transmission lines or low-impedance DAC buffers without external amplification. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supply - accommodates signals beyond rails in industrial sensor interfaces. |
| Slew Rate | 2.6 V/µs at ±15 V - supports 10 kHz full-scale sine wave output with <1% distortion into 10 kΩ. |
| Input Bias Current | ±10 pA typical - preserves signal integrity in photodiode or piezoelectric sensor circuits with >1 GΩ source impedances. |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables <10 pA input bias current and >1 TΩ input resistance for high-Z sensor interfacing. |
| High-output-drive capability | Guaranteed performance into 100 Ω loads - eliminates need for external buffer stages in low-impedance signal paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061CD | Higher input offset voltage (3 mV max vs. 2.6 mV), same SOIC-8 package and pinout. | Acceptable where system-level calibration compensates for offset; lower cost for non-critical channels. | Select when VIO tolerance >2.6 mV is acceptable and BOM cost optimization is prioritized. |
| TLV2461CD | Rail-to-rail output, higher supply current (550 μA), lower GBW (6.4 MHz), same SOIC-8 footprint. | Better for single-supply systems requiring output swing to rails; unsuitable for low-power or high-voltage (>6 V) use. | Choose only if rail-to-rail output is mandatory and supply current >5× increase is acceptable. |
Compared with TLE2061CD, the TLE2061ACD offers tighter offset specification for calibrated sensor chains; compared with TLV2461CD, it trades bandwidth and rail-to-rail output for micropower operation and ±18 V capability - critical for legacy industrial and aerospace platforms.

FAQ
What is the maximum operating temperature range for the TLE2061ACD?
The TLE2061ACD is rated for 0°C to 70°C ambient operation (C-suffix grade). This is confirmed in Table 4-1 of the TI datasheet, where "TLE2061ACD" appears under the "0°C to 70°C" row and "D (SOIC, 8)" column. It is not qualified for industrial (–40°C to +85°C) or military (–55°C to +125°C) temperature ranges - those require TLE2061AID or TLE2061AMJG variants respectively.
Does the TLE2061ACD support rail-to-rail input or output operation?
The TLE2061ACD supports rail-to-rail input common-mode range (e.g., –11 V to +13 V at ±15 V supply) but does not provide rail-to-rail output swing. Its output typically swings to within 1.5 V of each rail into 10 kΩ, and to ±12.5 V into 600 Ω at ±15 V supply - as specified in Section 5.5 of the datasheet. True rail-to-rail output requires devices like the TLV2461 series.
Is the TLE2061ACD pin-compatible with other TLE206x variants in SOIC-8 packages?
Yes - all TLE2061x variants in the D (SOIC-8) package share identical pinout, including TLE2061CD, TLE2061AID, and TLE2061ID. Figure 4-2 in the datasheet explicitly confirms the same top-view pin assignment for "TLE2061, TLE2061A, D, P Package", validating mechanical and electrical interchangeability at the board level.
What is the typical input bias current of the TLE2061ACD, and why does it matter?
The TLE2061ACD exhibits ±10 pA typical input bias current at 25°C, per Section 5.3 of the datasheet. This ultra-low value is critical when interfacing with high-impedance sources (e.g., pH electrodes, piezoelectric sensors, or photodiodes), as it minimizes voltage error across source impedances >100 MΩ and prevents signal droop in integrator or sample-hold circuits.
Can the TLE2061ACD drive a 100 Ω load, and what are the implications?
Yes - the TLE2061ACD is explicitly characterized for operation into 100 Ω loads, as stated in its "Features" list and confirmed in Section 5.11 (VOM– specification for D/P packages: "RL = 100Ω"). Driving such low impedances demands careful PCB layout (short traces, ground plane) and may reduce output swing by ~1.5 V peak-to-peak versus 10 kΩ loading, but eliminates need for external buffer stages in current-output DAC or line-driver applications.
