Texas Instruments TL062CD

Overview

TL062CD from Texas Instruments is a dual JFET-input operational amplifier designed for low-power, high-input-impedance signal conditioning in cost-sensitive analog circuits. It delivers 200 µA per amplifier supply current, 3.5 V/µs slew rate, and ±11 V common-mode input range extending to V_CC+, enabling use in rail-to-rail input-capable front-end stages of sensor interfaces and audio preamplifiers.

For engineers reviewing the TL062CD datasheet, TL062CD pinout, TL062CD application, or TL062CD equivalent, key selection criteria include its JFET-input architecture for picoampere-level bias current, unity-gain bandwidth of 1 MHz, and SOIC-8 packaging suitable for space-constrained industrial control and consumer electronics designs.

Technical Context

The TL062CD implements a two-stage JFET-input op amp topology with internal frequency compensation, delivering stable unity-gain operation without external compensation. Its differential pair uses matched JFETs to achieve ultra-low input bias current (30 pA typical at 25°C) and high input resistance (10¹² Ω).

It supports split-supply operation from ±5 V to ±15 V, features output short-circuit protection, and maintains latch-up-free behavior across –40°C to 85°C ambient temperature. Common-mode input voltage range includes V_CC+, allowing direct sensing of signals near the positive rail.

FAQ

What is the maximum supply voltage rating for TL062CD?

The TL062CD has an absolute maximum supply voltage rating of ±18 V across V_CC+ and V_CC−. Operation beyond this risks permanent device damage. For reliable long-term use, TI specifies recommended operating conditions of ±5 V to ±15 V, ensuring optimal performance and thermal safety within the –40°C to +85°C ambient range.

Does TL062CD support single-supply operation?

TL062CD is specified for dual-supply operation but can be used in single-supply configurations with appropriate biasing. Its common-mode input range extends to V_CC+, allowing the non-inverting input to accept signals up to the positive rail. However, the output swing does not reach the rails - minimum output is typically V_CC− + 1.5 V and maximum is V_CC+ – 1.5 V under load.

What is the input offset voltage specification for TL062CD?

TL062CD has a typical input offset voltage of 3 mV at 25°C, with a maximum of 15 mV over the full 0°C to 70°C commercial temperature range. The offset voltage drift is 10 µV/°C, meaning total drift over the full range adds ≤700 µV - critical for DC-coupled precision applications requiring stable baseline accuracy.

How does TL062CD compare to TL062CP in terms of package and performance?

TL062CD uses an SOIC-8 package (4.90 mm × 6.00 mm), while TL062CP uses an 8-pin PDIP package (9.59 mm × 7.94 mm). Electrically, both share identical specifications - same supply current, slew rate, input bias current, and thermal characteristics. The CD variant is optimized for surface-mount automation and improved thermal dissipation in compact layouts.

Is TL062CD suitable for driving capacitive loads?

TL062CD is not optimized for direct capacitive load driving above 100 pF without external compensation. Its internal compensation targets resistive loads ≥10 kΩ. Driving larger capacitive loads (e.g., cables or ADC input capacitance) may cause instability or ringing. For such cases, add a small series resistor (e.g., 50 Ω) between TL062CD output and the load to isolate capacitance and maintain phase margin.
