Texas Instruments TL064CDR

Overview

TL064CDR from Texas Instruments is a quad JFET-input operational amplifier optimized for low-power, high-input-impedance analog signal conditioning in cost-sensitive industrial and consumer systems. It delivers 200 µA per amplifier supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including V_CC+), and 10¹² Ω input resistance - enabling precision DC-coupled amplification in battery-powered sensors and audio front-ends.

For engineers reviewing the TL064CDR datasheet, TL064CDR pinout, TL064CDR application, or TL064CDR equivalent, key selection criteria include its JFET-input architecture for ultra-low bias current (30 pA typ.), rail-to-rail-compatible input stage, quad-channel integration in SOIC-14, and guaranteed operation from 0°C to 70°C under ±5 V to ±15 V dual supplies.

Technical Context

The TL064CDR implements a fully differential JFET-input stage with internal frequency compensation, delivering stable unity-gain operation without external components. Its high-impedance inputs and low input offset current (5 pA typ.) make it suitable for photodiode transimpedance amplifiers and high-impedance sensor interfaces where leakage must be minimized.

Designed as a low-power counterpart to the TL074 and TL084 families, the TL064CDR maintains comparable AC performance (1 MHz unity-gain bandwidth, 80 dB CMRR) while reducing quiescent current by ~50%. It supports single-supply operation via level-shifting input stages and includes output short-circuit protection across all four amplifiers.

Key Specifications

Pinout & Package

TL064CDR is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 8.65 mm × 6.00 mm, with standard 1.27 mm pitch and gull-wing leads. The package is RoHS-compliant and rated for surface-mount reflow assembly.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad JFET-input op amp applications.

Compared with TL064CDR, TL074CDR trades 12× higher quiescent power for 3.7× faster slew rate and lower noise, while TL084CDR offers extended voltage range at the cost of 10× higher input bias current - making TL064CDR optimal for low-power, high-impedance, cost-sensitive applications where 1 MHz bandwidth suffices.

FAQ

What is the maximum supply voltage rating for TL064CDR?

The TL064CDR has an absolute maximum supply voltage rating of ±18 V (36 V total). However, the recommended operating range is ±5 V to ±15 V. Operation at ±18 V is not guaranteed for parametric performance and may reduce long-term reliability. Always observe derating guidelines in TI's SLOS078N datasheet Section 6.1.

Does TL064CDR support single-supply operation?

Yes, TL064CDR supports single-supply operation with appropriate input biasing. Its common-mode input range extends to V_CC– + 4 V and V_CC+ – 4 V, allowing use with a 0 V ground reference when V_CC– = 0 V and V_CC+ = +15 V. Input signals must remain within this window to avoid phase reversal or clipping.

Is TL064CDR pin-compatible with TL074CDR or TL084CDR?

TL064CDR is pin-compatible with TL074CDR and TL084CDR in the SOIC-14 package (D package). All three share identical pin numbering, function mapping, and footprint. However, differences in quiescent current, input bias, and thermal characteristics require verification of system-level power dissipation and noise budgets before substitution.

What is the typical input offset voltage for TL064CDR?

The typical input offset voltage for TL064CDR is 3 mV at 25°C, with a maximum of 15 mV over the 0°C to 70°C operating range. This value is specified for the TL064C grade per Section 6.7 of the SLOS078N datasheet and applies uniformly across all four amplifiers in the device.

How does TL064CDR handle output short circuits?

TL064CDR includes internal output short-circuit protection that limits current to approximately 35 mA per amplifier during sustained short-to-ground or short-to-rail conditions. This feature prevents thermal runaway and allows indefinite operation without external current-limiting resistors, as confirmed in Section 1 Features and Absolute Maximum Ratings Table 6.1.
