Texas Instruments TLE2064AMDRG4

Overview

TLE2064AMDRG4 from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, ±18V max supply voltage, and high-output-drive capability into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in aerospace analog input modules and flight control units.

For engineers reviewing the TLE2064AMDRG4 datasheet, TLE2064AMDRG4 pinout, TLE2064AMDRG4 application, or TLE2064AMDRG4 equivalent, key selection criteria include its JFET-input architecture for ultra-low input bias current (≤3 pA), wide common-mode range (–11 V to +13 V at ±15 V supplies), and specified performance across –55°C to +125°C operating temperature.

Technical Context

The TLE2064AMDRG4 uses JFET-input transistors with on-chip Zener trimming for offset voltage stability, enabling DC precision in harsh environments. Its architecture delivers low noise (40–70 nV/√Hz), high slew rate (2.6 V/µs at ±15 V), and phase margin of 46°–58° depending on load and supply configuration.

It operates over ±3.5 V to ±18 V dual supplies, supports rail-to-rail output swing into high-impedance loads, and maintains stable unity-gain bandwidth (1.3–1.8 MHz) with 100 pF capacitive loading - critical for sensor interface and feedback loop integrity in safety-critical avionics subsystems.

FAQ

What is the maximum supply voltage rating for the TLE2064AMDRG4?

The TLE2064AMDRG4 has an absolute maximum supply voltage rating of ±18 V (36 V total), with recommended operating range from ±3.5 V to ±18 V. Operation beyond ±18 V risks permanent damage. This rating is validated across the full –55°C to +125°C temperature range, making TLE2064AMDRG4 suitable for high-voltage industrial and aerospace signal chains where transient overvoltage resilience is required.

Does the TLE2064AMDRG4 support rail-to-rail input or output operation?

The TLE2064AMDRG4 does not provide rail-to-rail input or output operation. Its common-mode input range extends to –11 V to +13 V at ±15 V supplies, and output swing reaches ±12.5 V into 600 Ω - approximately 2.5 V within each rail. While not rail-to-rail, this headroom is sufficient for most high-voltage sensor interfaces. The TLE2064AMDRG4's design prioritizes precision and drive strength over rail compliance, distinguishing it from general-purpose RRO op-amps.

What is the input bias current specification for the TLE2064AMDRG4 at –55°C?

At –55°C, the TLE2064AMDRG4 exhibits a maximum input bias current of 30 nA (per the TLE2064M Electrical Characteristics table, full-range specification). This value reflects worst-case behavior across the extended temperature range and remains significantly lower than bipolar-input alternatives. The JFET input architecture ensures that even at cryogenic temperatures, TLE2064AMDRG4 maintains sub-100 nA bias - critical for maintaining accuracy in high-impedance transducer circuits deployed in cold-soak aerospace environments.

Can the TLE2064AMDRG4 drive a 100 Ω load continuously without thermal shutdown?

Yes - the TLE2064AMDRG4 is explicitly characterized and specified for continuous operation into 100 Ω loads, with output voltage swing data provided for RL = 100 Ω in both the ±5 V and ±15 V test conditions. Thermal design must account for power dissipation: at ±15 V and full swing into 100 Ω, worst-case channel power is ~3.6 W. PCB layout must include adequate copper pour and thermal vias beneath the SOIC package to maintain junction temperature within limits. The TLE2064AMDRG4's 125°C max operating temperature and robust SOIC thermal resistance support this use case when properly mounted.

Is the TLE2064AMDRG4 pin-compatible with other devices in the TLE206x family?

Yes - the TLE2064AMDRG4 shares identical pinout and footprint with all TLE2064x variants in the 14-pin SOIC (D) package, including TLE2064CDR, TLE2064IDR, and TLE2064MDR. Pin functions (e.g., OUT A on pin 1, VCC– on pin 4, VCC+ on pin 12) are consistent across grades. However, electrical specifications - especially input offset voltage, temperature range, and long-term drift - differ significantly between M-grade (TLE2064AMDRG4) and commercial (C) or industrial (I) grades. Interchangeability requires validation of system-level DC and AC performance margins.
