Texas Instruments TL061ACDR

Overview

TL061ACDR 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, ±15 V max supply voltage, and 10¹² Ω input resistance - enabling high-impedance sensor interfacing in battery-powered white goods and personal electronics.

For engineers reviewing the TL061ACDR datasheet, TL061ACDR pinout, TL061ACDR application, or TL061ACDR equivalent, key selection criteria include its JFET-input architecture for ultra-low input bias current (30 pA typ), rail-to-rail common-mode input range extending to VCC+, output short-circuit protection, and SOIC-8 packaging suitable for space-constrained PCB layouts.

Technical Context

The TL061ACDR implements a JFET-input differential pair with internal frequency compensation, delivering stable unity-gain operation without external compensation. Its high input impedance and low input bias current make it suitable for photodiode amplification, piezoelectric sensor buffering, and high-impedance filter stages where leakage-induced errors must be minimized.

It operates across 0°C to 70°C (Commercial grade) with ±5 V to ±15 V dual-supply capability, supports common-mode input voltages from VCC– + 4 V to VCC+ – 4 V, and maintains 86 dB CMRR and 95 dB PSRR at 25°C - ensuring robust performance in noisy industrial environments.

FAQ

What is the maximum supply voltage rating for TL061ACDR?

The TL061ACDR has an absolute maximum supply voltage rating of ±18 V across VCC+ and VCC– terminals. However, the recommended operating range is ±5 V to ±15 V per the datasheet. Operating beyond ±15 V may compromise long-term reliability and is not guaranteed for parametric performance - always refer to Section 6.1 Absolute Maximum Ratings in the official TL061ACDR datasheet for derating guidance.

Does TL061ACDR support rail-to-rail input operation?

The TL061ACDR does not support full rail-to-rail input - its common-mode input voltage range extends from VCC– + 4 V to VCC+ – 4 V at 25°C. This means it accepts inputs within 4 V of each supply rail, enabling operation with signals near but not at the rails. For true rail-to-rail input, consider alternatives like the OPA350 series; the TL061ACDR's design prioritizes JFET-input impedance and low bias current over input voltage range extension.

Is TL061ACDR pin-compatible with other TL06x variants?

Yes - TL061ACDR shares identical 8-pin SOIC pinout with all TL061x variants (including TL061CDR, TL061BCDR, and TL061IDR). Pin functions - IN–, IN+, OUT, VCC+, VCC–, and NCs - are consistent across the TL061 family. However, electrical specifications (e.g., input offset voltage, temperature range) differ by suffix; TL061ACDR is rated for 0°C to 70°C with tighter initial VIO (3 mV max) than standard TL061CDR (5 mV max).

What is the typical input voltage noise density of TL061ACDR at 1 kHz?

The TL061ACDR exhibits a typical input voltage noise density of 30 nV/√Hz at 1 kHz, as specified in Section 6.10 Operating Characteristics of the datasheet. This value is confirmed for VCC± = ±15 V, TA = 25°C, and RL = 10 kΩ. Noise increases at lower frequencies due to 1/f corner; Figure 6-15 shows spectral behavior from 10 Hz to 10 MHz - critical for low-frequency sensor applications where integrated noise determines dynamic range.

Can TL061ACDR drive capacitive loads directly?

The TL061ACDR is not optimized for direct capacitive load driving: its internal compensation targets resistive loads ≥ 2 kΩ. Driving >100 pF without isolation resistance risks peaking or oscillation. For capacitive loads (e.g., ADC input capacitance or cable termination), add a 100 Ω to 500 Ω series resistor between TL061ACDR output and the load - this maintains stability while preserving bandwidth for most sensor interface use cases.
