Texas Instruments TL064CN

Overview

TL064CN from Texas Instruments is a quad JFET-input operational amplifier designed for low-power, high-input-impedance analog signal conditioning in cost-sensitive systems. It delivers 200 µA per amplifier supply current, 3.5 V/µs typical slew rate, ±15 V max supply voltage, and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained applications such as sensor front-ends and audio preamps.

For engineers reviewing the TL064CN datasheet, TL064CN pinout, TL064CN application, or TL064CN equivalent, key selection criteria include its JFET-input architecture (10¹² Ω input resistance), rail-to-rail common-mode range (VCC+ included), output short-circuit protection, and compatibility with ±5 V to ±15 V dual supplies across industrial temperature ranges.

Technical Context

The TL064CN uses a monolithic JFET-input differential pair stage followed by high-gain CMOS-compatible output circuitry, providing inherently low input bias currents (<200 pA at 25°C) and high DC accuracy. Its internal frequency compensation ensures stable unity-gain operation without external components.

It supports wide common-mode input voltage range (VCC– +4 V to VCC+ –4 V), operates over 0°C to 70°C ambient, and features integrated EMI/RF filters plus 1.5 kV HBM ESD rating - making it suitable for noisy industrial environments where signal integrity and robustness are critical.

Key Specifications

Pinout & Package

TL064CN is supplied in a 14-pin PDIP (Plastic Dual In-line Package), 19.31 mm × 7.94 mm footprint, with through-hole mounting and industry-standard pin spacing (2.54 mm).

FAQ

What is the maximum supply voltage for TL064CN?

The absolute maximum supply voltage for TL064CN is ±18 V (36 V total), but the recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding internal junction limits and degrading long-term reliability. The TL064CN datasheet specifies guaranteed performance only within the recommended range, and thermal dissipation must be verified at higher voltages using RθJA = 80 °C/W for the PDIP package.

Does TL064CN support rail-to-rail input or output?

TL064CN supports rail-to-rail input common-mode range - specifically, its inputs operate from VCC– +4 V up to VCC+, including the positive rail. However, its output swing is limited to ±10 V into 10 kΩ (±13.5 V typical), so it does not provide true rail-to-rail output. This behavior is inherent to its JFET-input, bipolar-output architecture and must be accounted for in headroom-sensitive designs.

How many amplifiers are integrated in TL064CN?

TL064CN integrates four independent, electrically isolated operational amplifiers in a single 14-pin PDIP package. Each amplifier has dedicated input and output terminals, with shared VCC+ and VCC− supply pins. All four channels exhibit matched specifications including input bias current, offset voltage, and slew rate - enabling synchronized multi-channel signal processing without inter-channel performance variation.

Is TL064CN suitable for single-supply operation?

TL064CN can be operated from a single supply (e.g., +15 V and ground) by biasing inputs and outputs at mid-rail (e.g., +7.5 V), but its specified common-mode and output swing ranges assume dual supplies. For true single-supply applications, external level-shifting or rail-splitting networks are required. The device's inclusion of VCC+ in the common-mode range simplifies this implementation compared to older op-amps.

What is the input offset voltage specification for TL064CN?

TL064CN has a maximum input offset voltage of 3 mV at 25°C and 20 mV across the full 0°C to 70°C operating temperature range. This parameter is measured per amplifier channel under open-loop conditions with RS = 50 Ω. The offset voltage drift is specified at 10 µV/°C, enabling predictable error modeling in precision DC amplification circuits where calibration is impractical.
