Texas Instruments TL064BCD

Overview

TL064BCD 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 0°C to 70°C operation.

For engineers reviewing the TL064BCD datasheet, TL064BCD pinout, TL064BCD application, or TL064BCD equivalent, this page provides verified specifications, SOIC-14 package details, real-world use cases in white goods and personal electronics, and validated alternative options for design continuity and sourcing flexibility.

Technical Context

The TL064BCD 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) minimizes loading on high-Z sources such as piezoelectric sensors or photodiode transimpedance nodes.

It supports dual-supply operation from ±5 V to ±15 V, features rail-to-rail common-mode input (V_CC– + 4 V to V_CC+ – 4 V), and provides output short-circuit protection. The device exhibits 80 dB CMRR and 80 dB PSRR at 25°C, with crosstalk attenuation of 120 dB between channels.

FAQ

What is the operating temperature range for TL064BCD?

The TL064BCD is rated for operation from 0°C to 70°C (commercial grade). This range is confirmed in Section 6.3 of the TI datasheet SLOS078N under Recommended Operating Conditions for TL06xC devices. The 'C' suffix explicitly denotes the 0°C to 70°C specification, distinguishing it from 'I' (–40°C to 85°C) and 'M' (–55°C to 125°C) variants. TL064BCD maintains full electrical performance within this ambient range.

Does TL064BCD support single-supply operation?

Yes, TL064BCD supports single-supply operation with appropriate biasing. Its common-mode input voltage range extends to V_CC+, allowing the non-inverting input to accept signals up to the positive rail. When operated from a single +15 V supply with V_CC– tied to ground, the input common-mode range is 0 V to +11 V. Output swing reaches ±10 V under load, making it viable for rail-referenced sensor interfaces when paired with proper level-shifting or reference generation.

What is the input offset voltage specification for TL064BCD?

Per Section 6.8 of the TI datasheet SLOS078N, TL064BCD has a maximum input offset voltage of 3 mV at 25°C and 5 mV across the full 0°C to 70°C operating range. This value is measured with V_CC± = ±15 V and R_S = 50 Ω. The 'B' grade indicates tighter initial offset versus the standard 'C' grade (3 mV max vs 15 mV max), making TL064BCD suitable for precision DC-coupled applications where baseline accuracy matters.

How does TL064BCD differ from TL064ACD?

TL064BCD and TL064ACD share identical pinout, package, and basic specifications but differ in input offset voltage grading. TL064BCD guarantees ≤3 mV max offset at 25°C, while TL064ACD specifies ≤6 mV max at 25°C. Both exhibit the same 200 µA supply current, 3.5 V/µs slew rate, and 1 MHz bandwidth. The 'B' grade offers tighter DC precision for applications like sensor calibration or reference buffering where minimal initial error is critical.

Is TL064BCD pin-compatible with other TL06x variants in SOIC-14?

Yes, TL064BCD is fully pin-compatible with all TL064x variants (e.g., TL064CD, TL064ACD, TL064ID) in the SOIC-14 (D) package. Pin configuration follows Figure 5-3 and Table 5-1 in the datasheet, with consistent assignment of 1OUT, 1IN–, 1IN+, V_CC+, 2IN+, 2IN–, 2OUT, V_CC–, 3OUT, 3IN+, 4IN+, 4IN–, and 4OUT across all TL064x part numbers in the D package. No PCB layout changes are needed when substituting within the same package.
