Product details
Overview
TLE2064CDR from Texas Instruments is a quad FET-input operational amplifier with 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 analog input modules and flight control units where rail-to-rail output swing and low noise are critical.
For engineers reviewing the TLE2064CDR datasheet, TLE2064CDR pinout, TLE2064CDR application, or TLE2064CDR equivalent, key selection criteria include its JFET-input architecture, 2mV max input offset voltage (C-grade), SOIC-14 package compatibility, and specified performance at ±5V and ±15V supplies across 0°C to 70°C operating range.
Technical Context
The TLE2064CDR implements a JFET-input stage with on-chip Zener trimming for DC precision, delivering low input bias current (±10pA typ) and high input impedance (6TΩ common-mode, 540GΩ differential). Its unity-gain stable design achieves 2.2V/µs slew rate and 46° phase margin with 10kΩ load and 100pF capacitance.
It operates over ±3.5V to ±18V dual supplies, supports common-mode input ranges from –11V to +13V at ±15V supplies, and maintains 15V peak-to-peak output swing into 10kΩ - enabling use in wide-dynamic-range sensor interfaces without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1MHz - enables stable closed-loop operation up to ~100kHz with moderate gain. |
| Supply Current per Channel | 120μA (typ) - allows battery-powered or energy-constrained systems to integrate four op-amps with minimal quiescent load. |
| Input Offset Voltage | ≤2mV (max, 25°C) - ensures ≤20mV error in unity-gain buffer applications with ±10V input range. |
| Output Drive Capability | Specified into 100Ω - supports direct driving of low-impedance loads like transmission lines or ADC reference buffers. |
| Slew Rate | 2.2V/µs (±5V, 25°C) - sufficient for settling 10V steps within 5µs at 0.1% accuracy. |
| Common-Mode Input Range | –11V to +13V (at ±15V supplies) - accommodates signals near negative rail without clipping in industrial sensor front-ends. |
| Input Bias Current | ±10pA (typ, 25°C) - minimizes voltage error across high-value source impedances (>1MΩ). |

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 |
|---|---|---|---|
| TLE2064ACD | Lower 1.5mV max input offset voltage (A-grade), same SOIC-14 package and pinout. | Required where DC accuracy exceeds 2mV limit - e.g., precision calibration circuits or high-resolution data acquisition. | Select TLE2064ACD when VIO budget is ≤1.5mV; otherwise TLE2064CDR offers cost-optimized C-grade performance. |
| TL074CD | Higher 16V/µs slew rate but higher 200μA/channel supply current and 10mV VIO max; same SOIC-14 footprint. | Suitable for AC-coupled audio or wideband signal paths where speed outweighs power and DC precision. | Choose TL074CD only if bandwidth >3MHz is needed; TLE2064CDR provides superior DC specs and 40% lower quiescent current. |
Compared with TLE2064ACD and TL074CD, the TLE2064CDR delivers optimal balance of ultra-low power (120μA/ch), FET-input precision (2mV VIO), and robust output drive - making it the preferred choice for battery-operated or thermally constrained industrial sensing nodes.

FAQ
What is the maximum supply voltage rating for the TLE2064CDR?
The TLE2064CDR has an absolute maximum supply voltage rating of ±18V (36V total), with recommended operating range from ±3.5V to ±18V. Operation beyond ±18V risks permanent damage. At ±15V supplies, it delivers ±13.7V output swing into 10kΩ, confirming robust rail utilization. Always observe derating curves in the datasheet for elevated temperature conditions.
Does the TLE2064CDR support operation with single-supply configurations?
Yes, the TLE2064CDR can operate from a single supply (e.g., VCC+ = +36V, VCC− = GND), provided the input common-mode and output swing remain within specified limits. Its common-mode input range extends to VCC− (ground) and up to VCC+ − 2V, and output swings to within ~1.3V of each rail. For true rail-to-rail input/output, external biasing or a different amplifier family is required.
What is the input bias current specification for the TLE2064CDR at 85°C?
At 85°C, the TLE2064CDR exhibits a maximum input bias current of 2nA (full temperature range spec), with typical values remaining below 100pA. This is confirmed in Section 5.7 of the datasheet under TLE2061I Electrical Characteristics - applicable to all C/I/M variants including TLE2064CDR due to shared JFET-input topology and process.
Is the TLE2064CDR pin-compatible with the TL074 series?
No, the TLE2064CDR is not pin-compatible with the TL074 series. While both are SOIC-14 quad op-amps, the TLE2064CDR uses a non-standard pinout: VCC− is on pin 4 and VCC+ on pin 12, whereas TL074 places VCC− on pin 4 and VCC+ on pin 8. Interchanging them without PCB modification will cause catastrophic failure. Always verify pin mapping using Figure 4-4 (TLE2064) and Figure 4-1 (TL074) in respective datasheets.
How does the TLE2064CDR's noise performance compare to earlier BiFET op-amps?
The TLE2064CDR delivers a lower noise floor than prior-generation low-power BiFET amplifiers, with 43nV/√Hz input voltage noise at 1kHz and 1.1µVPP (0.1Hz–10Hz). This improvement stems from optimized JFET geometry and trimming techniques - directly enabling higher-resolution measurements in DC-coupled sensor interfaces where 1/f noise dominates error budgets.
