Product details
Overview
TL064CNSR 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 TL064CNSR datasheet, TL064CNSR pinout, TL064CNSR application, or TL064CNSR equivalent, this page provides verified electrical specifications, SOIC-14 package details, functional pin mapping, real-world use cases in white goods and personal electronics, and two validated alternative op amps with documented differences.
Technical Context
The TL064CNSR implements a JFET-input differential pair with internal frequency compensation, enabling stable unity-gain operation without external components. Its high-impedance input stage (1012 Ω) and rail-to-rail common-mode range support precision sensing in single-supply or split-supply configurations up to ±15 V.
It features output short-circuit protection, latch-up-free operation, and integrated EMI/RF filtering-critical for noise-prone environments like motor control interfaces and audio front-ends. The device meets MIL-PRF-38535 test requirements where applicable and supports full-range thermal performance from 0°C to 70°C.

| Slew rate | 3.5 V/µs typical - supports clean amplification of signals up to ~100 kHz at 10 VPP |
| Unity-gain bandwidth | 1 MHz - allows stable closed-loop gain ≥1 with minimal phase margin loss |
| Input bias current | 30 pA typical at 25°C - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiodes) |
| Common-mode input range | –12 V to +15 V (with ±15 V supplies) - includes VCC+, enabling direct connection to positive rail referenced sources |
| Input offset voltage | 3 mV max at 25°C - ensures ≤30 mV total error in DC-coupled gain-of-10 stages |
| ESD rating (HBM) | 2000 V - exceeds IEC 61000-4-2 Level 2 for robust handling in manufacturing and field service |
Pinout & Package

Applications
| Smart Appliance Sensor Interface | Audio Line-Level Preamp |
|---|---|
Use Scenario: Signal conditioning for temperature, humidity, and pressure sensors in washing machines and refrigerators. IC Role / Device Role / Timing Role: Quad amplifier configures as two differential instrumentation amps (Ch1–Ch2) and two buffer stages (Ch3–Ch4) for multi-sensor analog front-end. Use Value: Low 200 µA per-amp supply current extends standby battery life; rail-inclusive common-mode range accommodates sensor outputs referenced to VCC+. |
Use Scenario: High-fidelity line-level amplification and tone control in portable speakers and docking stations. IC Role / Device Role / Timing Role: Ch1–Ch2 implement active bass/treble filters; Ch3–Ch4 serve as low-noise output buffers driving 10 kΩ DAC outputs. Use Value: 30 nV/√Hz input noise density preserves dynamic range; 3.5 V/µs slew rate avoids slew-induced distortion at 20 kHz full-scale. |
| Industrial Data Acquisition Channel | Power Supply Monitoring Circuit |
Use Scenario: Isolated analog input conditioning for PLC analog modules measuring 4–20 mA or 0–10 V process signals. IC Role / Device Role / Timing Role: Ch1–Ch2 used as precision current-to-voltage converters; Ch3–Ch4 provide gain and level-shifting before ADC sampling. Use Value: 3 mV max input offset ensures ≤0.03% full-scale error in 12-bit systems; 120 dB crosstalk prevents channel-to-channel interference. |
Use Scenario: Real-time monitoring of ±12 V and +5 V rails in embedded computing systems for fault detection and graceful shutdown. IC Role / Device Role / Timing Role: Four comparators (configured via resistive dividers) monitor each rail against reference thresholds using Ch1–Ch4 independently. Use Value: Wide common-mode range (–12 V to +15 V) accepts direct connection to negative rails; low supply current minimizes monitoring overhead. |
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 |
|---|---|---|---|
| TL074CDR | Higher supply current (2.5 mA/amp), 13 V/µs slew rate, lower input bias current (3 pA) | Better for wideband audio or fast-settling data acquisition; unsuitable for ultra-low-power battery systems | Select when bandwidth >3 MHz or noise <18 nV/√Hz is required; avoid if <500 µA total quiescent current is mandatory |
| TL084CDR | Higher supply current (1.4 mA/amp), 13 V/µs slew rate, wider temp range (–40°C to 85°C) | Preferred for automotive cabin electronics or extended-temperature industrial controllers | Choose for higher-speed signal paths or broader ambient operation; not recommended where 200 µA/amp is critical |
Compared with TL064CNSR, TL074CDR offers 6.5× higher speed but consumes 12.5× more current, while TL084CDR trades 7× higher power for extended temperature capability and improved noise performance - making TL064CNSR optimal for cost- and power-constrained consumer and white-goods applications.

FAQ
What is the maximum supply voltage for TL064CNSR?
The absolute maximum supply voltage for TL064CNSR is ±18 V, but the recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially at elevated ambient temperatures. Always observe derating curves in the datasheet's Thermal Information section for SOIC-14 packages.
Does TL064CNSR support single-supply operation?
Yes, TL064CNSR supports single-supply operation with its common-mode input range extending to VCC+. When powered from +15 V and ground, inputs can swing from –12 V to +15 V relative to ground, allowing direct interface with sensors referenced to the positive rail. Output swing remains limited to approximately 0 V to +10 V under load.
What is the input offset voltage specification for TL064CNSR?
TL064CNSR has a maximum input offset voltage of 3 mV at 25°C and 20 mV across the full 0°C to 70°C operating range. This value is specified for the C-grade version and applies to each of the four amplifiers individually - critical for precision DC-coupled applications such as strain gauge amplification or thermocouple conditioning.
How does TL064CNSR handle output short circuits?
TL064CNSR includes internal output short-circuit protection that limits current to safe levels during indefinite shorts to either supply rail or ground. This feature prevents thermal runaway and permanent damage, making it suitable for rugged applications like motor current sensing or test equipment where accidental shorts may occur.
Is TL064CNSR pin-compatible with other TL06x variants?
Yes, TL064CNSR shares identical pinout and footprint with all TL064x variants in SOIC-14 packaging (e.g., TL064ACNSR, TL064BCNSR), including matching electrical connections for VCC+, VCC−, and all four amplifier inputs/outputs. Differences lie only in trimmed offset voltage and temperature grade - not pin function or physical layout.
