Texas Instruments TL064CPW

Overview

TL064CPW 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 across –40°C to 85°C operation.

For engineers reviewing the TL064CPW datasheet, TL064CPW pinout, TL064CPW application, or TL064CPW equivalent, this page provides verified specifications, TSSOP-14 package details, real-world use cases in white goods and personal electronics, and two validated alternative op amps with documented functional and thermal differences.

Technical Context

The TL064CPW integrates four independent JFET-input amplifier stages in a single monolithic die, each featuring internal frequency compensation, latch-up-free architecture, and output short-circuit protection. Its high-impedance (10¹² Ω) input stage enables precision sensing with minimal loading on high-Z sources like piezoelectric transducers or photodiode amplifiers.

Designed as a lower-power counterpart to the TL074 and TL084 families, the TL064CPW maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. It supports dual-supply operation from ±5 V to ±15 V and exhibits 80 dB CMRR and 80 dB PSRR at 25°C.

FAQ

What is the maximum supply voltage rating for TL064CPW?

The TL064CPW has an absolute maximum supply voltage rating of ±18 V. However, its recommended operating range is ±5 V to ±15 V per amplifier. Operating at ±18 V risks exceeding thermal limits in the TSSOP-14 package, especially with multiple amplifiers active. For reliable long-term operation, TI specifies ±15 V as the upper limit in datasheet Section 6.3.

Does TL064CPW support single-supply operation?

Yes, TL064CPW supports single-supply operation with appropriate biasing. Its common-mode input range extends to V_CC+, allowing the non-inverting input to accept signals near the positive rail. To operate from a single 12 V supply, tie V_CC– to ground, bias inputs at 6 V (mid-rail), and use rail-to-rail output stages downstream if full swing is needed - the TL064CPW itself delivers ±10 V swing with ±15 V supplies but only ~10 V peak-to-peak with 12 V single supply.

What is the input offset voltage specification for TL064CPW?

The TL064CPW (C-grade, commercial temperature range) has a maximum input offset voltage of 15 mV at 25°C and 20 mV over the full 0°C to 70°C range. Typical value is 3 mV. This parameter is critical for DC-coupled applications like sensor amplification - for higher precision, consider the TL064AC variant (6 mV max) or TL064BC (3 mV max), both in the same PW package.

How does TL064CPW handle capacitive loads?

The TL064CPW is internally compensated for unity-gain stability with resistive loads but becomes unstable with capacitive loads >100 pF. When driving cables or ADC input capacitance, add a 100 Ω to 500 Ω isolation resistor between the TL064CPW output and the load capacitance. This breaks the feedback loop's phase shift - confirmed in Figure 7-1 of the datasheet and validated in TI's SLOA057 application note on driving capacitive loads.

Is TL064CPW pin-compatible with TL074CPW and TL084CPW?

Yes, TL064CPW is pin-compatible with TL074CPW and TL084CPW in the TSSOP-14 (PW) package - all share identical pin numbering, function mapping, and footprint. This allows drop-in replacement in existing layouts when upgrading speed or downgrading power. However, verify thermal dissipation: TL064CPW's 1.0 W max power in TSSOP-14 is lower than TL074CPW's 1.2 W, so high-output-current designs may require thermal review.
