Product details
Overview
TL064ACP 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, ±11 V common-mode input range (with VCC+ inclusion), and 1012 Ω input resistance - enabling precision DC-coupled amplification in battery-powered or thermally constrained applications such as sensor front-ends and portable audio.
For engineers reviewing the TL064ACP datasheet, TL064ACP pinout, TL064ACP application, or TL064ACP equivalent, key selection criteria include its JFET-input architecture for ultra-low bias current (≤200 pA at 25°C), rail-to-rail-compatible common-mode range, quad-channel integration in SOIC-14, and verified performance across 0°C to 70°C industrial temperature range.
Technical Context
The TL064ACP implements a JFET-input differential pair with internal frequency compensation, delivering unity-gain stability without external components. Its high-impedance input stage enables direct interfacing with high-Z sources like piezoelectric sensors or photodiode transimpedance nodes while maintaining low input offset voltage (max 15 mV) and low temperature drift (10 µV/°C).
It features output short-circuit protection and latch-up-free operation under recommended conditions (±5 V to ±15 V dual supply). The device supports wide common-mode voltage swing (VCC– + 4 V to VCC+ – 4 V) and achieves 1 MHz unity-gain bandwidth with 86 dB CMRR and 95 dB PSRR at 25°C.
Key Specifications

|---|---|
| Supply Current (per amp) | 200 µA typical - enables multi-amp operation in sub-1 mA total system bias budgets |

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 |
|---|---|---|---|
| TL074CP | Higher supply current (2.5 mA per amp), 13 V/µs slew rate, tighter offset (10 mV max) | Better for higher-speed or lower-offset requirements where power is not constrained | Choose TL074CP when bandwidth >3 MHz or offset <5 mV is required; avoid if <1 mA total supply budget applies |
| TL084CN | Higher input noise (18 nV/√Hz vs 30 nV/√Hz), same 200 µA supply current, no HBM rating specified | Legacy drop-in replacement with identical pinout but reduced ESD robustness | Use TL084CN only in legacy designs with existing qualification; TL064ACP preferred for new designs requiring 2-kV HBM compliance |
Compared with TL074CP and TL084CN, TL064ACP provides the lowest power consumption in the TL06x/TL07x/TL08x family while retaining full pin compatibility and industrial temperature support - making it optimal for energy-constrained, multi-channel analog front-ends where speed is secondary to efficiency and reliability.

FAQ
What is the maximum operating supply voltage for TL064ACP?
The TL064ACP supports dual-supply operation from ±5 V to ±15 V, with absolute maximum ratings of ±18 V. Operation beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, even if within absolute maximums. For TL064ACP, sustained use at ±15 V is validated across the 0°C to 70°C temperature range with proper PCB thermal relief.
Does TL064ACP require external compensation capacitors?
No, TL064ACP includes internal frequency compensation optimized for unity-gain stability. External compensation is unnecessary for standard inverting, non-inverting, or voltage-follower configurations. This simplifies layout and eliminates tuning steps - a key advantage of TL064ACP over decompensated op-amps like the TL084 series.
Can TL064ACP drive a 10 kΩ load across its full output swing?
Yes, TL064ACP delivers ±10 V minimum peak output swing into 10 kΩ loads at 25°C, and maintains ±10 V across its full 0°C to 70°C operating range. At ±15 V supplies, the typical swing reaches ±13.5 V, enabling full-scale utilization of 12-bit or 16-bit ADC references without clipping.
How does TL064ACP handle input voltages beyond the supply rails?
TL064ACP specifies a common-mode input voltage range of VCC– + 4 V to VCC+ – 4 V. Inputs exceeding this range may cause phase reversal or increased bias current. However, the device includes protection diodes that clamp inputs to rails - limiting damage risk if brief overvoltage occurs, though sustained operation outside VICR is not guaranteed.
Is TL064ACP pin-compatible with other quad op-amps in the TL06x/TL07x/TL08x families?
Yes, TL064ACP shares identical 14-pin SOIC pinout with TL074CP, TL084CN, and all TL064x variants (e.g., TL064ACN, TL064BCP). This allows direct substitution in existing layouts - provided supply current, noise, and slew rate requirements align with the application's performance envelope.
