Texas Instruments TL064ACDR

Overview

TL064ACDR 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 1 MHz unity-gain bandwidth across 0°C to 70°C operation.

For engineers reviewing the TL064ACDR datasheet, TL064ACDR pinout, TL064ACDR application, or TL064ACDR equivalent, key selection criteria include its JFET-input stage enabling picoampere-level bias current, rail-to-rail-compatible input voltage range, output short-circuit protection, and SOIC-14 packaging suitable for space-constrained PCB layouts in white goods and personal electronics.

Technical Context

The TL064ACDR implements a fully differential JFET-input stage with internal frequency compensation, supporting stable unity-gain operation without external components. Its high-impedance inputs (10¹² Ω) and low input bias current (30 pA typ. at 25°C) minimize loading on high-impedance sources such as piezoelectric sensors or photodiode transimpedance nodes.

Designed as a low-power counterpart to the TL074 and TL084 families, it maintains comparable AC performance-including 1 MHz bandwidth and 3.5 V/µs slew rate-while reducing quiescent current by ~50%. The device features integrated EMI/RF filters and 1.5 kV HBM ESD rating, enabling robust operation in electrically noisy environments.

FAQ

What is the maximum supply voltage for TL064ACDR?

The absolute maximum supply voltage for TL064ACDR is ±18 V, meaning V_CC+ may reach +18 V and V_CC– may reach –18 V. However, recommended operating conditions specify ±5 V to ±15 V. Exceeding ±18 V risks permanent damage, and operation above ±15 V voids guaranteed specifications per the datasheet. TL064ACDR must be biased within these limits to ensure reliability and parametric compliance.

Does TL064ACDR support rail-to-rail input or output?

TL064ACDR supports rail-to-rail *input* capability: its common-mode input voltage range extends to V_CC+, enabling signals up to the positive rail. However, its output swing is limited to ±10 V into 10 kΩ (with ±15 V supplies), so it does not provide rail-to-rail output. TL064ACDR is therefore ideal for input buffering but requires headroom for output stages driving downstream circuitry.

Can TL064ACDR replace TL074 or TL084 in existing designs?

TL064ACDR is pin-compatible with TL074CDR and TL084CDR in SOIC-14 packages and shares identical pin functions-but substitution requires verification of bandwidth, slew rate, and supply current impact. TL064ACDR's 1 MHz bandwidth and 3.5 V/µs slew rate are lower than TL074/TL084 (3 MHz, 13 V/µs), so high-speed circuits may need redesign. TL064ACDR is best suited for low-frequency, low-power upgrades-not drop-in replacements without analysis.

What is the input offset voltage specification for TL064ACDR?

TL064ACDR has a maximum input offset voltage of 6 mV at 25°C and 7.5 mV over the full 0°C to 70°C operating range. This value is specified for the "AC" grade variant per the Electrical Characteristics table (Section 6.7). The offset is temperature-stable, with a coefficient of only 10 µV/°C, making TL064ACDR suitable for precision DC-coupled applications where drift must remain minimal across ambient variations.

Is TL064ACDR suitable for single-supply operation?

Yes, TL064ACDR supports single-supply operation with appropriate biasing. Its common-mode input range includes the negative rail (V_CC–) and extends to within 4 V of V_CC+, allowing use with V_CC– = 0 V and V_CC+ = 5–15 V. For proper operation, input signals must stay within this range, and output swing will be limited accordingly. A mid-rail reference or level-shifting network may be needed for AC-coupled signals in true single-supply configurations.
