Texas Instruments TL064BCDR

Overview

TL064BCDR 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 TL064BCDR datasheet, TL064BCDR pinout, TL064BCDR application, or TL064BCDR equivalent, key selection criteria include its JFET-input stage enabling pA-level bias currents, rail-to-rail-compatible input voltage range, output short-circuit protection, and SOIC-14 packaging suitable for space-constrained PCB layouts in white goods and personal electronics.

Technical Context

The TL064BCDR implements a fully differential JFET-input stage with internal frequency compensation, supporting stable unity-gain operation without external components. Its architecture enables common-mode input voltage extension to V_CC+, critical for single-supply sensor interface and active filter designs.

Each of the four independent amplifiers features matched electrical characteristics-including 120 dB crosstalk attenuation, 80 dB CMRR, and 80 dB PSRR-ensuring minimal inter-channel interference and robust performance under varying supply conditions in multi-stage analog signal chains.

Key Specifications

Pinout & Package

TL064BCDR is housed in a 14-pin SOIC (D) package measuring 8.65 mm × 6.00 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. The package supports automated reflow soldering and offers thermal resistance R_θJA = 86°C/W.

FAQ

What is the operating temperature range for TL064BCDR?

The TL064BCDR is rated for operation from 0°C to 70°C ambient temperature. This commercial-grade specification aligns with the 'C' suffix in the part number and is validated per Electrical Characteristics Table 6.8 in the TI datasheet SLOS078N. All key parameters-including input offset voltage, bias current, and slew rate-are guaranteed across this full range.

Does TL064BCDR support single-supply operation?

Yes, TL064BCDR 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. For true single-supply use, V_CC– must be tied to ground and V_CC+ set to the desired supply voltage (5 V to 15 V), with input signals referenced accordingly.

What is the maximum output voltage swing for TL064BCDR?

At ±15 V supplies and 25°C, TL064BCDR delivers ±13.5 V peak output swing into a 10 kΩ load. Under full-range conditions (0°C to 70°C), the guaranteed minimum is ±10 V. Output swing degrades linearly with decreasing load resistance-e.g., ±10 V is maintained down to 2 kΩ loads per the large-signal differential voltage amplification spec.

How does TL064BCDR differ from TL064ACDR?

TL064BCDR specifies tighter input offset voltage: 2 mV (max) at 25°C versus 3 mV for TL064ACDR. Both share identical supply current (200 µA), slew rate (3.5 V/µs), and package (SOIC-14). The 'B' grade is selected when lower initial DC error is required in precision DC-coupled circuits without needing the 'A' grade's enhanced AC performance.

Is TL064BCDR pin-compatible with other TL06x variants in SOIC-14?

Yes, TL064BCDR is pin-compatible with all TL064x variants (e.g., TL064CDR, TL064ACDR, TL064IDR) in the SOIC-14 (D) package. Pin functions-including 1OUT, 1IN–, 1IN+, V_CC+, 2IN+, 2IN–, 2OUT, 3OUT, 3IN–, V_CC–, 3IN+, 4IN+, 4IN–, and 4OUT-are identical across the TL064x family in this package, enabling drop-in replacement within the same grade temperature range.
