Product details
Overview
TL064CDT from STMicroelectronics is a low-power JFET-input quad operational amplifier designed for precision analog signal conditioning in space-constrained industrial and instrumentation systems. It delivers 200 µA supply current per amplifier, 3.5 V/µs slew rate, ±11.5 V input common-mode range (with ±15 V supplies), and 1 MHz gain-bandwidth product - enabling stable DC-coupled amplification and AC signal processing in multi-channel sensor front-ends.
For engineers reviewing the TL064CDT datasheet, TL064CDT pinout, TL064CDT application, or TL064CDT equivalent, this device is selected for low-noise, low-quiescent-current analog stages where high input impedance (>1012 Ω), rail-to-rail input capability, and channel isolation (>120 dB) are critical - especially in audio distribution, transducer signal conditioning, and battery-powered data acquisition.
Technical Context
The TL064CDT integrates four matched JFET-input op-amp cells on a single monolithic die, each featuring internal frequency compensation, output short-circuit protection, and latch-up-free operation. Its JFET input stage enables ultra-low input bias current (≤400 pA typ.) and high input resistance, making it suitable for high-impedance source interfacing such as piezoelectric sensors and photodiode transimpedance stages.
It operates over ±6 V to ±18 V dual supplies (or 12–36 V single supply), with guaranteed performance across 0°C to +70°C ambient. The SO-14 package supports surface-mount assembly while maintaining thermal resistance (RthJA) of 105 °C/W - critical for sustained operation in compact enclosures without forced airflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current (per amp) | 200 µA typical - enables multi-amp designs in battery-powered systems with >1-year runtime on coin cells. |
| Slew rate | 3.5 V/µs - supports clean 100 kHz small-signal amplification with <10% overshoot at 10 kΩ load. |
| Input bias current | 30–400 pA max - preserves signal integrity when amplifying from MΩ-range sources like pH electrodes. |
| Input resistance | 1012 Ω - minimizes loading error in high-Z sensor interfaces and passive filter networks. |
| Gain-bandwidth product | 1 MHz - allows stable unity-gain follower or gain-of-10 configurations up to ~100 kHz. |
| Common-mode rejection | 80–86 dB - rejects power-supply ripple and ground noise in differential measurement setups. |
| Channel separation | 120 dB - prevents crosstalk between adjacent channels in multi-signal routing applications. |
Pinout & Package
TL064CDT is housed in a 14-lead SOIC (SO-14) plastic micropackage with 1.27 mm pitch, 8.55–8.75 mm body width, and 5.8–6.2 mm body length - optimized for automated SMT placement and thermal dissipation in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp 1) | High-impedance node for feedback network connection in inverting amplifier topologies. |
| 2 | Non-inverting Input (Amp 1) | Accepts high-Z sensor signals without attenuation; common-mode range extends to VCC–. |
| 3 | Output (Amp 1) | Capable of sourcing/sinking ±20 mA; short-circuit protected to prevent latch-up during fault conditions. |
| 4 | VCC– (Negative Supply) | Reference for all four amplifiers; must be decoupled locally with ≥100 nF ceramic capacitor. |
| 5 | Inverting Input (Amp 2) | Independent input stage; no internal coupling - enables true isolated dual-channel operation. |
| 6 | Non-inverting Input (Amp 2) | Matches Amp 1 characteristics; usable for differential pair or independent signal path. |
| 7 | Output (Amp 2) | Electrically isolated from Amp 1 output; supports independent load driving up to 10 kΩ. |
| 8 | VCC+ (Positive Supply) | Shared supply rail for all four amplifiers; requires local 100 nF bypass near pin 8. |
| 9 | Inverting Input (Amp 3) | Third identical input stage; enables triple-sensor buffering or cascaded filtering stages. |
| 10 | Non-inverting Input (Amp 3) | Supports rail-to-rail common-mode input; compatible with single-supply configurations down to 12 V. |
| 11 | Output (Amp 3) | Drives loads independently; output swing reaches ±13.5 V into 10 kΩ with ±15 V supplies. |
| 12 | Inverting Input (Amp 4) | Fourth channel input; pin-compatible with industry-standard quad op-amp footprints. |
| 13 | Non-inverting Input (Amp 4) | Enables simultaneous 4-channel signal conditioning without external multiplexing. |
| 14 | Output (Amp 4) | Final output stage; maintains 120 dB channel separation from Amp 1–3 outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Very low power consumption | 200 µA per amplifier - reduces total system quiescent current by >60% vs. bipolar-input quads (e.g., LM324). |
| High input impedance JFET stage | 1012 Ω input resistance - eliminates loading errors in piezoelectric accelerometer and electret microphone circuits. |
| Wide common-mode voltage range | ±11.5 V with ±15 V supplies - supports direct interface to sensors operating near supply rails. |
| Output short-circuit protection | Indefinite short-circuit duration to either rail - prevents damage during board-level test or connector miswiring. |
| Latch-up free operation | Guaranteed under all specified conditions - ensures reliability in noisy industrial environments with ESD transients. |
Applications
| Audio Signal Distribution | Transducer Signal Conditioning |
|---|---|

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 |
|---|---|---|---|
| TL074CDT | Higher slew rate (13 V/µs), lower input noise (18 nV/√Hz), but 2.5× higher supply current (1.4 mA/amp). | Better for wideband audio or fast transient capture; unsuitable for ultra-low-power battery systems. | Select TL074CDT only when bandwidth >10 MHz or noise <20 nV/√Hz is required - not for power-sensitive designs. |
| RC4136DT | Lower input offset (0.5 mV max), wider supply range (±4 V to ±22 V), but no SO-14 packaging option for RC4136 variants. | Preferred for high-accuracy DC measurements; requires DIP-14 or SOIC-16 footprint adaptation. | Choose RC4136DT when offset voltage is critical and board layout permits alternate package; verify thermal derating for SOIC-16. |
Compared with TL064CDT, TL074CDT trades 5× higher power for 4× faster response and half the noise, while RC4136DT offers superior DC precision but lacks drop-in SO-14 compatibility - making TL064CDT the optimal balance of low power, quad integration, and surface-mount readiness.

FAQ
What is the maximum supply voltage for TL064CDT?
The absolute maximum supply voltage is ±18 V (36 V total), but the recommended operating range is ±6 V to ±18 V dual supply or 12–36 V single supply. Operation beyond ±18 V risks permanent damage to the JFET input stage and violates ST's absolute maximum ratings - design margins should maintain at least 1 V headroom below ±18 V for reliability.
Does TL064CDT support single-supply operation?
Yes - TL064CDT operates with single supplies from 12 V to 36 V. Its input common-mode range extends to VCC– (ground), allowing direct interface to 0–5 V sensor outputs when biased at mid-supply using resistive dividers and decoupling capacitors. Output swing remains within 1.5 V of each rail under 10 kΩ load.
How does TL064CDT compare to TL062CDT in quad-channel applications?
TL064CDT integrates four independent amplifiers in one SO-14 package, whereas TL062CDT contains only two amplifiers in SO-8. Using two TL062CDTs instead of one TL064CDT increases PCB area by 30%, adds two extra supply decoupling networks, and raises total quiescent current by ~10% due to duplicated bias circuitry - making TL064CDT more space- and power-efficient for true quad implementations.
Is TL064CDT RoHS-compliant and ECOPACK® certified?
Yes - TL064CDT is manufactured in ST's ECOPACK®-compliant SO-14 package, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The device uses lead-free terminations and halogen-free molding compounds, with full compliance documentation available in ST's ECOPACK® database at www.st.com/ecopack.
