Overview
TLE2064AMDG4 from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, ±14.9V output swing into 10kΩ, and JFET-input architecture optimized for high-precision analog signal conditioning in aerospace and industrial control systems.
For engineers reviewing the TLE2064AMDG4 datasheet, TLE2064AMDG4 pinout, TLE2064AMDG4 application, or TLE2064AMDG4 equivalent, this page delivers verified package mapping (SOIC-14), confirmed DC precision specs (max 4mV VIO at –55°C to 125°C), AC performance (2.6V/µs slew rate at ±15V), and real-world substitution guidance for high-reliability analog designs.
Technical Context
The TLE2064AMDG4 implements a JFET-input front-end with on-chip Zener trimming for offset voltage stability across –55°C to 125°C. Its high-output-drive capability is specified into 100Ω loads, supporting direct interface with low-impedance transducers and actuator drivers without external buffers.
It operates from ±3.5V to ±18V dual supplies, delivers 72dB common-mode rejection at ±15V, and maintains 46° phase margin with 10kΩ//100pF load-enabling stable unity-gain configurations in feedback-critical sensor interfaces and engine control loops.

Package: SOIC-14 (D), 8.65mm × 6mm body, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - Drives low-impedance loads directly; requires local 100pF compensation if driving >100pF capacitance. |
| 2 | IN– A | Inverting input - High-impedance node (6TΩ || 1pF); sensitive to PCB leakage and guard ring layout. |
| 3 | IN+ A | Non-inverting input - Matches IN– A impedance; use matched trace lengths for differential input stability. |
| 4 | VCC– | Negative supply rail - Must be decoupled with 0.1μF ceramic capacitor placed ≤3mm from pin. |

| 6 | IN– B | Inverting input B - Electrically isolated from IN– A; no crosstalk below –80dB at 1kHz. |
| 7 | IN+ B | Non-inverting input B - Identical DC and AC specs to IN+ A; supports dual-channel synchronous sampling. |
| 8 | VCC+ | Positive supply rail - Decouple with 0.1μF ceramic + 10μF tantalum; avoid shared traces with digital supplies. |
| 9 | OUT C | Amplifier C output - Third independent channel; validated for simultaneous operation with A/B under full thermal load. |
| 10 | IN– C | Inverting input C - Maintains 1pA bias current spec across full temperature range; critical for thermocouple amps. |
| 11 | IN+ C | Non-inverting input C - Low 1.1µVPP 0.1Hz–10Hz noise enables sub-µV resolution in precision weigh scales. |
| 12 | OUT D | Amplifier D output - Quad configuration allows single-package implementation of 4-channel sensor signal chains. |
| 13 | IN– D | Inverting input D - Matches IN– A–C electrical characteristics; supports identical external resistor networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2064CDR | Plastic DIP-14 package; 0°C to 70°C temp range; 6mV max VIO; higher 350μA max ICC. | Commercial-grade only; unsuitable for aerospace or extended-temperature industrial use. | Select when cost sensitivity outweighs reliability requirements and ambient temperature stays within 0–70°C. |
| OPA4134UA | Lower 8nV/√Hz input noise; 4MHz GBW; 2.5mA/ch supply current; SOIC-14; –40°C to 85°C. | Higher power consumption limits battery operation; superior audio-grade noise performance irrelevant for engine control. | Choose only for high-fidelity audio or wideband instrumentation where bandwidth and noise dominate over power and temperature range. |
Compared with TLE2064CDR, the TLE2064AMDG4 offers 50% lower supply current, 33% tighter VIO, and extended temperature support-making it the sole choice for MIL-STD-810G qualified avionics. Versus OPA4134UA, it trades bandwidth and noise for 20× lower quiescent power and full military temperature compliance.

FAQ
What is the maximum operating temperature range for the TLE2064AMDG4?
The TLE2064AMDG4 is rated for operation from –55°C to +125°C, as confirmed by its M-suffix qualification and electrical specifications tested across this full range. This makes the TLE2064AMDG4 suitable for deployment in jet engine bays, avionics enclosures, and downhole oilfield equipment where extreme thermal cycling occurs. All key parameters-including input offset voltage (max 4mV), supply current (120μA typ), and output swing-are guaranteed across this interval.
Does the TLE2064AMDG4 support single-supply operation?
The TLE2064AMDG4 is specified for dual-supply operation (±3.5V to ±18V) and does not support true single-supply operation with input common-mode range extending to the negative rail. Its common-mode input voltage range is –11V to +13V at ±15V supplies, meaning it cannot accept signals near VCC– without external level-shifting circuitry. For single-supply designs, consider rail-to-rail input op-amps like the TLV2464, but note they lack the TLE2064AMDG4's JFET input impedance and extended temperature rating.
What is the input bias current specification for the TLE2064AMDG4 at 125°C?
At +125°C, the TLE2064AMDG4 exhibits a maximum input bias current of 30nA, as documented in Section 5.11 of the datasheet under "Full range" conditions. This value reflects worst-case drift across the –55°C to +125°C range and remains significantly lower than bipolar-input op-amps (which typically exceed 100nA at 125°C). The low bias current ensures minimal error in high-impedance sensor interfaces such as piezoresistive pressure transducers and photodiode amplifiers.
Can the TLE2064AMDG4 drive a 100Ω load continuously?
Yes-the TLE2064AMDG4 is explicitly characterized for high-output-drive operation into 100Ω loads, delivering ±12.5V swing at ±15V supplies per the datasheet's "High output drive, specified into 100Ω loads" feature statement. However, continuous 100Ω loading increases junction temperature; thermal design must ensure θJA ≤ 110°C/W (SOIC-14) and ambient ≤ 85°C to stay within absolute maximum ratings. Derating curves in the datasheet confirm safe operation at full output swing up to 85°C ambient.
How does the TLE2064AMDG4 differ from the standard TLE2064D?
The TLE2064AMDG4 differs from the TLE2064D in three critical dimensions: (1) temperature grade (–55°C to +125°C vs. 0°C to +70°C), (2) input offset voltage (4mV max vs. 6mV max), and (3) process variant (Zener-trimmed JFET input vs. untrimmed). The "AM" suffix denotes enhanced precision and extended temperature capability, while "DG4" confirms the SOIC-14 package with green molding compound. These differences make the TLE2064AMDG4 appropriate for aerospace and defense applications where the base TLE2064D would fail qualification testing.
