Product details
Overview
TL064BCN 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 VCC+), and 1 MHz unity-gain bandwidth across 0°C to 70°C operation.
For engineers reviewing the TL064BCN datasheet, TL064BCN pinout, TL064BCN application, or TL064BCN equivalent, this page provides verified specifications, SOIC-14 package details, quad-channel op amp functional context, and validated alternative options for precision analog front-ends requiring low bias current and rail-to-rail-compatible input stage behavior.
Technical Context
The TL064BCN implements a JFET-input differential pair with internal frequency compensation, enabling stable unity-gain operation without external compensation. Its high-impedance input stage (1012 Ω) and low input bias current (30 pA typ. at 25°C) support high-source-impedance sensor interfaces and precision integrators.
It features output short-circuit protection, latch-up-free operation, and integrated EMI/RF filtering. The device operates from dual supplies of ±5 V to ±15 V and supports common-mode input voltage up to VCC+, enabling single-supply configurations with level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables battery-powered or energy-constrained designs with four independent gain stages. |
| Slew Rate | 3.5 V/µs typical - supports audio-band signal amplification and moderate-speed waveform generation without distortion. |
| Input Bias Current | 30 pA typical at 25°C - minimizes voltage error in high-impedance transducer interfaces (e.g., piezoelectric sensors, pH electrodes). |
| Common-Mode Range | –12 V to +15 V (with ±15 V supplies) - includes VCC+, allowing direct connection to rail-referenced signals without level shifters. |
| Unity-Gain Bandwidth | 1 MHz - suitable for active filters, instrumentation amplifiers, and anti-aliasing stages up to ~100 kHz closed-loop bandwidth. |
| Input Resistance | 1012 Ω - preserves signal integrity in photodiode, capacitive sensor, and electrometer applications. |
| CMRR | 80 dB minimum - rejects power supply ripple and shared-noise coupling in multi-stage analog chains. |
Pinout & Package
TL064BCN is supplied in a 14-pin plastic DIP (PDIP-14) package measuring 19.31 mm × 7.94 mm, with through-hole mounting and industry-standard pin spacing (0.1 inch). Pin 1 is located at the left end of the top row when viewed from the top with the notch or dot oriented upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives loads ≥10 kΩ; short-circuit protected. |
| 2 | 1IN− | Inverting input of first amplifier - high-impedance JFET node; sensitive to layout-induced leakage. |
| 3 | 1IN+ | Non-inverting input of first amplifier - accepts common-mode voltages up to VCC+. |
| 4 | VCC− | Negative supply rail - must be decoupled locally with 0.1 µF ceramic capacitor. |
| 5 | 2IN+ | Non-inverting input of second amplifier - electrically isolated from other channels; crosstalk attenuation >120 dB. |
| 6 | 2IN− | Inverting input of second amplifier - matched to Pin 2 for common-mode rejection in dual configurations. |
| 7 | 2OUT | Output of second amplifier - independently buffered; no internal inter-channel coupling. |
| 8 | VCC+ | Positive supply rail - referenced for all input common-mode and output swing specifications. |
| 9 | 3OUT | Output of third amplifier - identical electrical characteristics to Pins 1 and 7. |
| 10 | VCC− | Shared negative supply - all four amplifiers share this pin; requires low-impedance return path. |
| 11 | 3IN+ | Non-inverting input of third amplifier - matches Pin 3 in offset and bias performance. |
| 12 | 4IN+ | Non-inverting input of fourth amplifier - enables fully independent 4-channel signal processing. |
| 13 | 4IN− | Inverting input of fourth amplifier - symmetrical layout recommended to match Pin 2. |
| 14 | 4OUT | Output of fourth amplifier - full rail-to-rail compatible swing within ±10 V (±15 V supplies). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL064CDR | Same electrical specs but SOIC-14 surface-mount package; 86 °C/W RθJA vs 80 °C/W for PDIP. | Better thermal performance in compact PCBs; requires reflow soldering instead of through-hole assembly. | Select TL064CDR for automated SMT production and space-constrained layouts where thermal margin is critical. |
| TL074CN | Higher slew rate (13 V/µs), lower noise (18 nV/√Hz), but 1.4 mA supply current per amplifier - 7× higher power. | Superior for wideband audio or high-fidelity instrumentation; unsuitable for battery-powered or thermally limited systems. | Choose TL074CN only when bandwidth and noise dominate over power and thermal constraints. |
Compared with TL064BCN, TL064CDR offers identical analog performance in a smaller footprint with improved thermal resistance, while TL074CN trades significant power efficiency for enhanced speed and noise performance - making TL064BCN optimal for cost- and power-sensitive industrial and white-goods applications.

FAQ
What is the operating temperature range for TL064BCN?
The TL064BCN is rated for operation from 0°C to +70°C ambient temperature. This commercial-grade specification aligns with its "C" suffix designation and makes it suitable for indoor consumer and industrial equipment where extreme thermal environments are not expected. Full electrical parameters - including input offset voltage, bias current, and CMRR - are guaranteed across this range per the datasheet's TL06xC characterization tables.
Does TL064BCN support single-supply operation?
Yes, TL064BCN supports single-supply operation due to its extended common-mode input voltage range that includes VCC+. When powered from a single +15 V rail with VCC− grounded, the input can accept signals up to +15 V. However, output swing remains asymmetric (typically +10 V max), so proper biasing of the non-inverting input (e.g., at VCC/2) is required for AC-coupled applications. The TL064BCN does not feature rail-to-rail output.
How does TL064BCN differ from TL064ACN?
TL064BCN offers tighter input offset voltage specifications: 2 mV maximum at 25°C versus 3 mV for TL064ACN. Its input offset voltage drift is also lower (5 µV/°C typical vs 7.5 µV/°C), and full-range offset is specified at 5 mV (vs 7.5 mV for TL064ACN). These improvements make TL064BCN preferable in precision DC-coupled applications like sensor amplification where offset error directly impacts measurement accuracy.
Is TL064BCN pin-compatible with other quad op amps in PDIP-14?
Yes, TL064BCN uses the industry-standard 14-pin PDIP pinout defined for quad op amps (e.g., LM324, TL074, TL084), with identical assignments for VCC+, VCC−, and all eight input/output terminals. This allows drop-in replacement in existing designs - though electrical differences (e.g., JFET vs bipolar input, supply current, slew rate) must be verified for functional compatibility in the target circuit.
What decoupling is recommended for TL064BCN?
A 0.1 µF ceramic capacitor placed as close as possible to Pins 4 (VCC−) and 8 (VCC+) is mandatory for stable operation. For systems with noisy power rails or multiple TL064BCN units, add a 10 µF tantalum or aluminum electrolytic capacitor near the board's main supply entry point. Avoid long traces between decoupling caps and supply pins to prevent resonance and instability, especially in high-gain configurations.
