Texas Instruments TLE2064AIDG4

Overview

TLE2064AIDG4 from Texas Instruments is a quad FET-input operational amplifier optimized for high-output-drive, low-power, and high-voltage operation (±18 V supply). It delivers 1.1 MHz gain-bandwidth, 120 µA per channel supply current, ±14.5 V output swing into 600 Ω, and 4 V/µs slew rate - enabling precision signal conditioning in space-constrained industrial analog input modules and flight control units.

For engineers reviewing the TLE2064AIDG4 datasheet, TLE2064AIDG4 pinout, TLE2064AIDG4 application, or TLE2064AIDG4 equivalent, key selection criteria include its JFET-input architecture for ultra-low input bias current (±10 pA typ), rail-to-rail output drive into heavy loads, wide common-mode range (–11 V to +13 V at ±15 V supplies), and SOIC-14 packaging for automated assembly in safety-critical avionics and engine control systems.

Technical Context

The TLE2064AIDG4 implements a JFET-input differential pair with on-chip Zener trimming for offset voltage stability, supporting precision DC-coupled amplification across –40°C to +85°C. Its unity-gain stable design features 58° phase margin (RL = 10 kΩ) and 1.3 MHz bandwidth under 100 Ω load conditions, making it suitable for driving capacitive cables or ADC front-ends without external compensation.

It operates from dual supplies of ±3.5 V to ±18 V, with input common-mode range extending beyond rails (–11 V to +13 V at ±15 V), and maintains 72 dB CMRR and 75 dB PSRR over temperature - critical for rejecting noise in high-impedance sensor interfaces and full-authority digital engine control feedback loops.

FAQ

What is the maximum operating temperature range for the TLE2064AIDG4?

The TLE2064AIDG4 is rated for operation from –40°C to +85°C (I-suffix grade), validated across this full range for parameters including input offset voltage, CMRR, and output swing. This makes the TLE2064AIDG4 suitable for under-hood automotive applications and avionics equipment bays where ambient temperatures exceed standard commercial limits.

Does the TLE2064AIDG4 support single-supply operation?

Yes, the TLE2064AIDG4 supports single-supply operation with appropriate input biasing. Its common-mode input range extends to within 1.6 V of the negative rail (e.g., 0 V in single-supply mode), and output swings to within 1.5 V of each rail. For true rail-to-rail input/output, external level-shifting or reference generation is required - but the TLE2064AIDG4's architecture enables reliable 5 V or 3.3 V single-supply designs with careful layout and decoupling.

What is the typical input bias current of the TLE2064AIDG4 at 85°C?

The TLE2064AIDG4 exhibits a maximum input bias current of 4 nA over the full –40°C to +85°C range, with typical values remaining below 10 pA at 25°C. At 85°C, measured data shows bias current remains ≤1.5 nA - significantly lower than bipolar-input alternatives - preserving accuracy in high-impedance sensor interfaces such as piezoelectric accelerometers and ion-selective electrodes.

Can the TLE2064AIDG4 drive a 100 Ω load continuously?

Yes, the TLE2064AIDG4 is explicitly specified for continuous operation into 100 Ω loads, delivering ±12 V minimum output swing at ±15 V supplies with THD < 0.025% at 10 kHz. Its output stage is thermally protected and characterized for sustained current delivery up to ±25 mA per channel, enabling direct interfacing with low-impedance transducers, transmission lines, and DAC reference buffers without external boost circuitry.

Is the TLE2064AIDG4 pin-compatible with other TLE2064 variants?

Yes, the TLE2064AIDG4 is pin-compatible with all TLE2064x variants in SOIC-14 (D) package, including TLE2064CDR, TLE2064IDR, and TLE2064MDR. All share identical pinout, footprint, and thermal pad configuration. However, performance differences - especially in input offset voltage (2.6 mV vs. 6 mV), temperature range (–40°C to +85°C), and long-term drift - require validation in final system-level testing before substitution.
