Product details
Overview
TL064CD 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 - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained designs.
For engineers reviewing the TL064CD datasheet, TL064CD pinout, TL064CD application, or TL064CD equivalent, key selection criteria include its JFET-input stage (1012 Ω input resistance), rail-to-rail-compatible input voltage range, low 5 pA typical input offset current, and SOIC-14 package suitability for space-constrained PCB layouts.
Technical Context
The TL064CD implements a fully differential JFET-input stage with internal frequency compensation, supporting stable unity-gain operation without external compensation. Its high-impedance inputs and low bias currents minimize loading on high-source-impedance sensors and passive filter networks.
It operates from dual supplies of ±5 V to ±15 V, with guaranteed performance across 0°C to 70°C (Commercial grade). The device features output short-circuit protection and latch-up-free design, making it robust in mixed-signal environments with transient coupling or power sequencing variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current (per amp) | 200 µA typical - enables multi-amplifier configurations in ultra-low-power systems (e.g., sensor front-ends drawing <1 mA total). |
| Input bias current | 30 pA typical at 25°C - preserves accuracy in high-impedance transducer interfaces (e.g., piezoelectric or photodiode amplifiers). |
| Slew rate | 3.5 V/µs typical - supports faithful reproduction of audio-band signals (≤100 kHz) and fast-settling DC-coupled stages. |
| Unity-gain bandwidth | 1 MHz - sufficient for active filters, instrumentation gain blocks, and anti-aliasing stages up to ~100 kHz. |
| Input resistance | 1012 Ω - prevents signal attenuation in circuits with MΩ-level source impedances (e.g., pH electrodes, capacitive sensors). |
| Common-mode input range | Includes VCC+ - allows direct interfacing to single-ended sensors referenced to positive rail (e.g., current-sense amps, level shifters). |
| ESD rating (HBM) | 2000 V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD immunity in consumer electronics. |
Pinout & Package
TL064CD 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 suitable for reflow soldering.
| 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+ | Positive 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. |
| 7 | 2OUT | Output of second amplifier - independent output stage; no shared internal nodes with other amps. |
| 8 | VCC− | Negative supply rail - reference for all four amplifiers; requires symmetric decoupling. |
| 9 | 3OUT | Output of third amplifier - identical electrical specs to Pins 1 and 7; supports parallel output configurations. |
| 10 | 3IN− | Inverting input of third amplifier - pin-compatible with TL062/TL061 input structures. |
| 11 | 3IN+ | Non-inverting input of third amplifier - supports rail-to-rail input operation when VCM ≤ VCC+ − 4 V. |
| 12 | 4IN+ | Non-inverting input of fourth amplifier - enables quad-channel signal conditioning without external multiplexing. |
| 13 | 4IN− | Inverting input of fourth amplifier - matched pair with Pin 12 for balanced differential gain stages. |
| 14 | 4OUT | Output of fourth amplifier - full 12 Vpp swing into 10 kΩ at ±15 V supplies; usable down to ±5 V. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input architecture | Delivers 1012 Ω input resistance and sub-100 pA bias current - critical for high-precision sensor signal chains. |

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 |
|---|---|---|---|
| TL074CD | Higher supply current (2.5 mA per amp), 13 V/µs slew rate, lower input bias current (3 pA typ), same SOIC-14 package. | Better suited for high-speed, low-noise applications where power budget allows; not drop-in due to 12.5× higher quiescent current. | Select TL074CD only when bandwidth >3 MHz or noise <18 nV/√Hz is required; TL064CD remains optimal for power-constrained designs. |
| TL084CD | Higher supply current (1.4 mA per amp), 13 V/µs slew rate, wider common-mode range (±12 V), same SOIC-14 footprint. | Preferred for high-slew applications like active filters or video buffers; lacks rail-inclusive input range of TL064CD. | Choose TL084CD for speed-critical signal paths; TL064CD is superior for precision, low-power, high-Z sensor interfaces. |
Compared with TL074CD and TL084CD, the TL064CD trades speed and ultra-low bias current for dramatically lower power consumption and rail-inclusive input capability - making it uniquely suitable for always-on sensor nodes and portable equipment where thermal and battery life constraints dominate.

FAQ
What is the maximum supply voltage for TL064CD?
The TL064CD supports dual supply voltages from ±5 V to ±15 V. Absolute maximum ratings specify ±18 V, but operation beyond ±15 V risks exceeding thermal limits and degrading long-term reliability. For stable performance across temperature, TI recommends staying within the recommended operating conditions of ±5 V to ±15 V as defined in Section 6.3 of the TL064CD datasheet.
Does TL064CD support single-supply operation?
Yes, TL064CD can operate from a single supply (e.g., +15 V and ground), provided the input common-mode voltage remains within VCC− + 4 V to VCC+ − 4 V. Its ability to accept inputs up to VCC+ simplifies single-supply designs - for example, using a resistor divider to bias inputs at mid-rail while retaining full dynamic range at the output.
What is the input offset voltage specification for TL064CD?
The TL064CD has a maximum input offset voltage of 15 mV at 25°C and 20 mV across the full commercial temperature range (0°C to 70°C). This value applies to the TL064C grade; tighter specifications (e.g., 6 mV max) are available in the TL064AC variant. Input offset drift is specified at 10 µV/°C, enabling predictable calibration in temperature-varying environments.
How does TL064CD compare to TL064CP in terms of package and performance?
The TL064CD uses a 14-pin SOIC package (8.65 mm × 6.00 mm), while TL064CP uses a 14-pin PDIP package (19.31 mm × 7.94 mm). Electrically, both share identical specifications - same supply current, slew rate, input bias current, and temperature range. The choice depends solely on assembly method: SOIC for surface-mount reflow, PDIP for through-hole prototyping or legacy wave-solder processes.
Is TL064CD suitable for driving capacitive loads?
TL064CD is not optimized for direct capacitive load driving above 100 pF without isolation. Its internal compensation targets resistive loads ≥10 kΩ. For capacitive loads (e.g., cables or ADC inputs), TI recommends adding a series resistor (≥200 Ω) between the output and load to maintain phase margin and prevent oscillation - verified in Figure 6-13 of the TL064CD datasheet.
