Texas Instruments TL064IPWR

Overview

TL064IPWR 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 V_CC+), and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained designs such as sensor front-ends and audio preamps.

For engineers reviewing the TL064IPWR datasheet, TL064IPWR pinout, TL064IPWR application, or TL064IPWR equivalent, this page provides verified electrical specifications, SOIC-14 package layout, real-world use cases in white goods and personal electronics, and two validated alternative op amps with documented parameter and application differences.

Technical Context

The TL064IPWR implements a JFET-input differential pair with internal frequency compensation, delivering rail-to-rail common-mode input capability (V_CM includes V_CC+) and latch-up-free operation across –40°C to 85°C. Its high 10¹² Ω input resistance and low 30 pA typical input bias current minimize loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes.

Each of its four independent amplifiers features output short-circuit protection and 120 dB crosstalk attenuation, supporting multi-channel signal paths without inter-stage coupling. The device maintains stable unity-gain performance with 1 MHz bandwidth and 3.5 V/µs slew rate under ±15 V supplies and 10 kΩ loads - suitable for active filters, voltage followers, and precision gain stages where power efficiency and input integrity are critical.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage rating for TL064IPWR?

The absolute maximum supply voltage for TL064IPWR is ±18 V, meaning V_CC+ can reach +18 V and V_CC– can reach –18 V. However, the recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially in the SOIC-14 package where R_θJA is 86°C/W. Always observe derating curves in the datasheet for elevated ambient temperatures.

Does TL064IPWR support single-supply operation?

Yes, TL064IPWR supports single-supply operation with appropriate input biasing. Its common-mode input range extends to V_CC+, allowing direct connection of signals referenced to the positive rail. For true single-supply use (e.g., 0 V and +12 V), configure the non-inverting input at mid-rail using a resistor divider and bypass capacitor, and ensure output swing remains within V_OM limits (±10 V typical with ±15 V supplies, reduced proportionally at lower voltages).

What is the input offset voltage specification for TL064IPWR?

TL064IPWR has a maximum input offset voltage of 6 mV at 25°C and 20 mV across the full operating temperature range (–40°C to +85°C). This value applies to the "I" grade (industrial temperature range) variant specified in the TL064I electrical characteristics table. The offset voltage drift is 10 µV/°C, enabling predictable calibration in precision DC applications like strain gauge amplifiers.

How does TL064IPWR compare to TL084 in terms of power consumption?

TL064IPWR consumes significantly less power than TL084: 200 µA per amplifier versus 1.4 mA per amplifier - a 7× reduction. This makes TL064IPWR suitable for always-on sensor nodes and portable devices where thermal management and battery life are critical. TL084 trades power for higher slew rate (13 V/µs) and bandwidth (4 MHz), so TL064IPWR is preferred when <1 MHz bandwidth suffices and quiescent current must be minimized.

Is TL064IPWR pin-compatible with other quad op amps in SOIC-14 packages?

TL064IPWR uses the industry-standard SOIC-14 pinout for quad op amps (pin 1 = OUT A, pin 2 = IN– A, pin 3 = IN+ A, etc.), matching TL074, TL084, and RC4136. However, electrical differences - especially supply current, input bias, and common-mode range - mean direct substitution requires verification of circuit stability, offset, and thermal margins. No formal pin-to-pin guarantee exists outside TI's own TL06x family.
