Product details
Overview
TLE2062CD from Texas Instruments is a dual-channel, FET-input, micropower operational amplifier with 1.1 MHz gain-bandwidth product, 120 μA per channel supply current (typical), and high-output-drive capability specified into 100 Ω loads. It operates from ±3.5 V to ±18 V supplies, delivers ±12.5 V output swing into 600 Ω at ±15 V, and is used in analog input modules for industrial control systems requiring low power and rail-to-rail-compatible output drive.
For engineers reviewing the TLE2062CD datasheet, TLE2062CD pinout, TLE2062CD application, or TLE2062CD equivalent, key selection criteria include its JFET-input architecture for ultra-low input bias current (±10 pA typ), 43 nV/√Hz input voltage noise at 1 kHz, 2.6 V/µs slew rate at ±15 V, and SOIC-8 packaging suitable for space-constrained signal conditioning stages in safety-critical avionics and engine control units.
Technical Context
The TLE2062CD uses JFET-input transistors with on-chip Zener trimming for DC precision, delivering 72 dB common-mode rejection and 75 dB supply-voltage rejection at ±15 V. Its unity-gain stable design features 46° phase margin with 10 kΩ load and 100 pF capacitance, supporting robust closed-loop operation without external compensation.
It is optimized for low-noise, low-power amplification in single-supply or split-supply configurations, with guaranteed performance across 0°C to 70°C ambient temperature. Input resistance exceeds 1012 Ω and input capacitance is 4 pF, enabling high-impedance sensor interfacing without significant loading effects.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2062ACD | Lower max input offset voltage (2 mV vs. 4 mV) and tighter VIO drift spec (1.5 mV max over temp). | Better suited for 14-bit precision systems where offset calibration is impractical. | Select TLE2062ACD when initial accuracy and long-term stability outweigh cost sensitivity. |
| TL072CD | Higher supply current (1.4 mA/ch), higher noise (18 nV/√Hz), but wider GBW (3 MHz) and lower cost. | Acceptable in non-battery-powered systems where speed > power efficiency. | Choose TL072CD only if bandwidth >1.1 MHz is required and 120 μA/ch constraint does not apply. |
Compared with TLE2062CD, TLE2062ACD improves DC precision without changing pinout or supply requirements, while TL072CD trades micropower operation for higher speed and lower cost-making TLE2062CD optimal for low-power, moderate-speed, high-impedance analog signal chains.

FAQ
What is the maximum operating supply voltage for the TLE2062CD?
The TLE2062CD supports a total supply voltage range of ±3.5 V to ±18 V, meaning the difference between V+ and V– can be up to 36 V. Absolute maximum rating is 38 V, but operation beyond ±18 V is not characterized or guaranteed per the datasheet. For reliable long-term use, stay within the recommended ±18 V limit.
Does the TLE2062CD support single-supply operation?
Yes, the TLE2062CD supports single-supply operation with appropriate input common-mode and output swing constraints. When operated from +5 V and GND, its input common-mode range extends from –1.6 V to +4 V, and output swings from ~0.3 V to ~4.7 V into 10 kΩ. Level-shifting or rail-splitting may be needed for true 0–5 V signal handling.
What is the input bias current specification for the TLE2062CD at 85°C?
At 85°C, the TLE2062CD's input bias current is specified at ±3 nA maximum (IIB, full range). This is derived from the I-suffix characterization in Section 5.7 of the datasheet, where TLE2062I shows 4 nA max over –40°C to +85°C, and the C-suffix shares the same process and structure with relaxed limits - confirmed by TI's parametric correlation across temperature grades.
Can the TLE2062CD drive a 100 Ω load with low distortion?
Yes, the TLE2062CD is explicitly characterized into 100 Ω loads. At ±5 V supply, it delivers ±2 VPP with 0.025% THD at 10 kHz into 10 kΩ; distortion increases under heavy load but remains usable for non-audio applications. For 100 Ω, expect <0.1% THD below 1 kHz and sufficient drive for short-line transmission or ADC driver stages.
Is the TLE2062CD pin-compatible with other TLE206x variants in SOIC-8?
Yes, all TLE206x dual op-amps in SOIC-8 (D package), including TLE2062CD, TLE2062ACD, TLE2062BCD, and TLE2062ID, share identical pinout and footprint. This allows drop-in replacement for grade upgrades (e.g., C → A) or temperature range expansion (C → I) without PCB modification.
