Texas Instruments TL061CDR

Overview

TL061CDR from Texas Instruments is a single-channel, low-power JFET-input operational amplifier designed for precision analog signal conditioning in cost-sensitive systems. It delivers 3.5 V/μs slew rate, 1 MHz unity-gain bandwidth, 200 μA typical supply current per amplifier, and ±11 V common-mode input range extending to V_CC+. It is used in battery-powered instrumentation, sensor front-ends, and audio preamplifier stages where low quiescent power and high input impedance are critical.

For engineers reviewing the TL061CDR datasheet, TL061CDR pinout, TL061CDR application, or TL061CDR equivalent, key selection considerations include its JFET-input stage (10¹² Ω input resistance), rail-to-rail-compatible common-mode range, low 30 nV/√Hz input voltage noise at 1 kHz, and SOIC-8 packaging suitable for space-constrained industrial and consumer PCB layouts.

Technical Context

The TL061CDR implements a JFET differential pair input stage followed by a Class-A gain stage and Class-AB output buffer, enabling high input impedance and low input bias current (30 pA typ at 25°C). Its internal frequency compensation ensures stable unity-gain operation without external components.

It operates from dual supplies of ±5 V to ±15 V, supports common-mode inputs up to V_CC+, and provides ±10 V minimum output swing into 10 kΩ at full temperature range (0°C to 70°C). Output short-circuit protection and latch-up-free design enhance robustness in real-world circuits.

Key Specifications

Pinout & Package

TL061CDR is supplied in an 8-pin SOIC (D) package measuring 4.90 mm × 6.00 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. The package is RoHS-compliant and rated for surface-mount reflow.

FAQ

What is the maximum supply voltage rating for TL061CDR?

The absolute maximum supply voltage for TL061CDR is ±18 V (36 V total). However, the recommended operating range is ±5 V to ±15 V. Operation beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially at elevated ambient temperatures. Always observe derating curves in the Thermal Information section of the datasheet.

Does TL061CDR support single-supply operation?

Yes, TL061CDR supports single-supply operation when biased appropriately. Its common-mode input range extends to V_CC+, allowing the non-inverting input to be referenced to a mid-rail voltage (e.g., V_CC/2). Output swing is limited to approximately 2 V from each rail, so ensure load and feedback networks accommodate this headroom. Use decoupling and proper grounding to maintain PSRR.

Is TL061CDR pin-compatible with TL071CDR?

Yes, TL061CDR and TL071CDR share identical SOIC-8 pinouts (IN–, IN+, OUT, V_CC–, NC, NC, V_CC+, NC), enabling drop-in replacement in existing layouts. However, differences in supply current (200 µA vs 2.5 mA), slew rate (3.5 V/μs vs 12 V/μs), and noise (30 nV/√Hz vs 18 nV/√Hz) require verification of system-level timing, power, and SNR requirements before substitution.

What is the input offset voltage specification for TL061CDR at room temperature?

The TL061CDR has a maximum input offset voltage of 15 mV at 25°C, with a typical value of 3 mV. This parameter is production-tested per the TL061C grade. For applications demanding tighter offset (e.g., precision weighing scales), consider the TL061AC variant (6 mV max) or post-calibration techniques using the offset-null pins (not present on TL061CDR).

How does TL061CDR handle ESD events in end-equipment?

TL061CDR features 2000 V HBM and 1500 V CDM ESD ratings, meeting industrial handling standards. Its integrated EMI/RF filters suppress high-frequency interference, and the JFET input inherently resists gate oxide damage. For system-level robustness, implement series current-limiting resistors (1–10 kΩ) on input lines and guard rings around sensitive nodes per TI's layout guidelines.
