Texas Instruments TLE2061AID

Overview

TLE2061AID from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for high-voltage (±18 V), low-power (120 μA typical supply current), and high-output-drive applications. It delivers 1.1 MHz gain-bandwidth, 2.2 V/µs slew rate at ±5 V, and rail-to-rail output swing into 10 kΩ - enabling precision signal conditioning in aerospace analog input modules and flight control unit sensor interfaces.

For engineers reviewing the TLE2061AID datasheet, TLE2061AID pinout, TLE2061AID application, or TLE2061AID equivalent, key selection criteria include its –40°C to +85°C industrial temperature grade, 1.5 mV max input offset voltage at 25°C, SOIC-8 package compatibility, and FET-input architecture for ultra-low input bias current (±10 pA typical).

Technical Context

The TLE2061AID implements a JFET-input differential pair with on-chip Zener trimming for offset voltage calibration, delivering stable DC precision across temperature. Its high open-loop gain (≥15 V/mV into 10 Ω) and 46° phase margin ensure stability in unity-gain configurations with capacitive loads up to 100 pF.

Designed for operation from ±3.5 V to ±18 V, it supports wide common-mode input range (–11 V to +13 V at ±15 V supplies) and drives heavy loads - specified down to 100 Ω in SOIC-8 - making it suitable for driving ADC drivers, active filters, and transducer signal chains where low noise (43 nV/√Hz at 1 kHz) and low distortion (0.025% THD) are critical.

FAQ

What is the maximum operating temperature range for the TLE2061AID?

The TLE2061AID is rated for operation from –40°C to +85°C, validated across its full specification range per TI's SLOS193D datasheet. This industrial temperature grade ensures reliable performance in engine bays, avionics bays, and outdoor industrial enclosures where ambient extremes are expected. The device maintains all key parameters - including 1.5 mV max input offset voltage and 120 μA typical supply current - within this range.

Does the TLE2061AID require external offset nulling components?

No, the TLE2061AID does not require external offset nulling. It uses on-chip Zener trimming to achieve its 1.5 mV max input offset voltage specification at 25°C. Pins 1 and 7 are designated as offset null terminals in the base TLE2061 design but are internally unconnected (NC) in the 'A' grade variant - confirmed in Figure 4-2 and Table 4-1 of the datasheet. No external potentiometer or circuitry is needed.

Can the TLE2061AID drive a 100 Ω load reliably in SOIC-8 package?

Yes, the TLE2061AID is explicitly specified to drive 100 Ω loads in SOIC-8 (D) package per datasheet Section 1 and electrical characteristics tables. At ±15 V supplies, it delivers ±12.5 V output swing into 600 Ω and maintains stability and linearity - critical for driving transmission lines, ADC driver stages, or low-impedance filters without external buffers.

How does the input bias current of the TLE2061AID compare to bipolar-input op-amps?

The TLE2061AID features JFET-input architecture with ±10 pA typical input bias current at 25°C and ≤2 nA maximum over –40°C to +85°C. This is 3–4 orders of magnitude lower than bipolar-input op-amps like the LM324 (≈30 nA typ), enabling accurate amplification of signals from high-impedance sources such as piezoelectric sensors, pH electrodes, or photodiodes without significant DC error or signal droop.

Is the TLE2061AID pin-compatible with other members of the TLE206x family?

Yes, the TLE2061AID is pin-compatible with all TLE2061 variants in SOIC-8 (D) package, including TLE2061CD, TLE2061ID, and TLE2061MD. Pin assignments (IN+, IN–, OUT, VCC±, NC) match identically per Figure 4-2. However, performance grades differ - e.g., TLE2061CD has 3 mV max VIO and commercial temp range - so electrical validation is required when substituting across grades.
