Texas Instruments TL061IDR

Overview

TL061IDR from Texas Instruments is a single-channel, low-power JFET-input operational amplifier designed for precision analog signal conditioning in cost-sensitive industrial and consumer systems. It delivers 200 µA typical supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including V_CC+), and 10¹² Ω input resistance - enabling high-impedance sensor interfacing in battery-powered or thermally constrained applications such as white goods control modules.

For engineers reviewing the TL061IDR datasheet, TL061IDR pinout, TL061IDR application, or TL061IDR equivalent, key selection criteria include its JFET-input architecture for ultra-low input bias current (30 pA typ.), rail-to-rail-compatible common-mode range, internal frequency compensation for unity-gain stability, and SOIC-8 packaging suitable for automated assembly in space-constrained PCB layouts.

Technical Context

The TL061IDR implements a JFET-input differential pair with high-impedance cascode gain stage and Class AB output buffer, delivering stable DC precision and wideband AC performance without external compensation. Its input stage supports common-mode voltages up to V_CC+, enabling direct sensing of signals referenced to the positive rail - critical in single-supply instrumentation front-ends.

Designed as a low-power variant of the TL07x/TL08x families, the TL061IDR maintains comparable bandwidth (1 MHz unity-gain) and CMRR (80 dB min) while reducing quiescent current by ~50%. It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, supporting robust operation in electrically noisy environments like appliance motor control feedback loops.

Key Specifications

FAQ

What is the maximum supply voltage rating for TL061IDR?

The absolute maximum supply voltage for TL061IDR is ±18 V (36 V total). However, the recommended operating range is ±5 V to ±15 V. Operating beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially in SOIC-8 packages with limited heat dissipation capability. Always verify junction temperature under worst-case load conditions using R_θJA = 97°C/W.

Does TL061IDR require external compensation capacitors?

No, TL061IDR includes internal frequency compensation and is unity-gain stable without external components. This eliminates capacitor placement uncertainty and board area usage. The device maintains phase margin >45° across all gains ≥1, provided proper power supply decoupling (0.1 µF ceramic per supply pin) and layout practices (short traces, ground plane) are followed.

Can TL061IDR operate with a single supply?

Yes, TL061IDR supports single-supply operation with common-mode input range extending to V_CC+. For example, with V_CC+ = 12 V and V_CC– = 0 V, inputs can range from –12 V to +12 V relative to ground. Output swing is typically ±10 V into 10 kΩ, so for true rail-to-rail output, a dedicated rail-to-rail op-amp like OPA344 is required - TL061IDR is optimized for dual-supply precision, not single-supply headroom.

What is the input offset voltage drift specification for TL061IDR?

TL061IDR has a temperature coefficient of input offset voltage (αV_IO) of 10 µV/°C maximum across the full operating range. At 25°C, input offset voltage is 3 mV max; over –40°C to +85°C (industrial grade), it increases to 9 mV max. This drift behavior is fully characterized and applies to all TL061 variants including TL061IDR - critical for DC-coupled applications requiring stable baseline over temperature.

How does TL061IDR compare to TL061CP in terms of performance and packaging?

TL061IDR (SOIC-8) and TL061CP (PDIP-8) share identical electrical specifications, including supply current, slew rate, and input offset voltage. The primary difference is package: TL061IDR uses a surface-mount SOIC with 4.90 mm × 6.00 mm footprint and 1.27 mm pitch, while TL061CP uses through-hole PDIP with 9.59 mm × 7.94 mm dimensions. Thermal resistance differs (R_θJA = 97°C/W vs 85°C/W), making TL061CP slightly more tolerant of higher ambient temperatures in low-airflow environments.
