Texas Instruments TLE2061IP

Overview

TLE2061IP from Texas Instruments is a single-channel, JFET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA typical supply current, ±14.9V output swing into 10kΩ at ±15V supplies, and specified high-output-drive performance into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in aerospace flight control units and industrial analog input modules.

For engineers reviewing the TLE2061IP datasheet, TLE2061IP pinout, TLE2061IP application, or TLE2061IP equivalent, this page delivers verified electrical characteristics, package-specific terminal mapping for the PDIP-8 (P) variant, thermal and voltage ratings for extended temperature operation (–40°C to +85°C), and validated alternative options for design continuity.

Technical Context

The TLE2061IP uses JFET-input transistors with on-chip Zener trimming for offset voltage stability across its –40°C to +85°C operating range. Its architecture supports rail-to-rail input common-mode range (–11 V to +13 V at ±15 V supplies) and delivers 2.6 V/µs slew rate with 46° phase margin under unity-gain conditions.

It features ultra-low input bias current (±10 pA typ. at 25°C), high input impedance (6 TΩ || 1 pF common-mode), and low noise (40 nV/√Hz at 1 kHz), enabling high-impedance sensor interfacing and precision DC-coupled amplification without significant loading or drift.

FAQ

What is the maximum operating temperature range for the TLE2061IP?

The TLE2061IP is rated for continuous operation from –40°C to +85°C, as confirmed by its I-suffix designation and electrical characterization data across that full range in the official TI datasheet SLOS193D. This makes the TLE2061IP suitable for industrial control cabinets and avionics bays where ambient temperatures exceed commercial-grade limits. The TLE2061IP maintains all key specifications-including input offset voltage, slew rate, and output swing-within published limits across this interval.

Does the TLE2061IP support rail-to-rail input or output operation?

The TLE2061IP does not provide rail-to-rail input or output operation. Its common-mode input range extends to –11 V and +13 V with ±15 V supplies, and its output swing reaches ±12.5 V into 600 Ω-leaving ~2.5 V headroom from each rail. This behavior is inherent to its JFET-input, bipolar-output stage architecture. For true rail-to-rail performance, alternate devices such as the OPA333 or TLV2461 would be required-but those lack the TLE2061IP's 36 V supply rating and 100 Ω drive guarantee.

Can the TLE2061IP drive a 100 Ω load reliably?

Yes-the TLE2061IP is explicitly characterized and specified for operation into 100 Ω loads, as stated in both the "Features" and "Electrical Characteristics" sections of the TI datasheet. At ±15 V supplies, it delivers ±12.5 V output swing into 600 Ω and maintains stability and THD <0.025% at 10 kHz with 10 kΩ loads. While direct 100 Ω drive is supported, layout best practices-including local decoupling and minimized output trace inductance-are required to preserve phase margin and prevent oscillation.

What is the input bias current specification for the TLE2061IP over temperature?

The TLE2061IP exhibits a maximum input bias current of 4 nA across its full operating range of –40°C to +85°C, per Section 5.7 and 5.9 of the TI datasheet SLOS193D. At 25°C, typical IIB is ±10 pA. This ultra-low bias enables accurate interfacing with high-impedance sources such as piezoelectric sensors, pH electrodes, and photodiodes without introducing measurable offset or leakage error-critical for long-integration-time measurement systems.

Is the TLE2061IP pin-compatible with other members of the TLE206x family?

Yes-the TLE2061IP shares identical PDIP-8 pinout with all single-channel TLE206x variants including TLE2061CP, TLE2061CD, and TLE2061ID. Pin functions (IN+, IN–, OUT, VCC+, VCC–, NC) are consistent across the family. However, electrical performance differs: the I-suffix guarantees operation to +85°C, while C-suffix parts are limited to +70°C. Substituting TLE2061IP for a C-suffix device maintains full mechanical and electrical compatibility but adds thermal margin without circuit modification.
