Product details
Overview
TLE2064CN from Texas Instruments is a quad FET-input operational amplifier with 1.1 MHz gain-bandwidth product, ±3.5 V to ±18 V supply range, and 120 μA per channel supply current. It delivers high-output drive into 100 Ω loads and features low input bias current (±10 pA typ), low noise (43 nV/√Hz at 1 kHz), and rail-to-rail output swing capability in PDIP-14 package. It is used in analog input modules for industrial control systems requiring precision, low power, and robust output drive.
For engineers reviewing the TLE2064CN datasheet, TLE2064CN pinout, TLE2064CN application, or TLE2064CN equivalent, this page provides verified electrical specifications, package dimensions, functional pin definitions, real-world use cases in safety-critical analog signal conditioning, and validated alternative options for design flexibility and supply continuity.
Technical Context
The TLE2064CN uses JFET-input transistors for ultra-low input bias current and On-chip Zener trimming for offset voltage stability across temperature. Its architecture supports high common-mode rejection (72 dB min at ±15 V) and supply-voltage rejection (75 dB min), enabling reliable operation in noisy industrial environments.
It operates over 0°C to 70°C (C-suffix grade), supports dual-supply configurations up to ±18 V, and maintains stable unity-gain phase margin (46°) with 10 kΩ load and 100 pF capacitance - critical for closed-loop sensor interface designs without external compensation.

| Input Bias Current | ±10 pA (typ) - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, piezoelectric sensors). |
| Output Drive Capability | Specified into 100 Ω - delivers ±2.5 V swing at 100 Ω load, supporting direct driving of ADC reference buffers or low-Z transmission lines. |
| Input Offset Voltage | 6 mV (max, full temp range) - ensures <0.5% error in 12-bit 5 V full-scale measurement systems without trimming. |
| Common-Mode Rejection Ratio | 72 dB (min at ±15 V) - rejects >90% of coupled noise on differential sensor inputs in motor-drive feedback loops. |
| Supply-Voltage Rejection Ratio | 75 dB (min) - suppresses ripple and noise from shared power rails in multi-amplifier signal chains. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2064CD | SOIC-14 package (8.65 mm × 6 mm); same electrical specs but surface-mount compatible. | Preferred for automated PCB assembly and space-constrained layouts; lacks through-hole mechanical retention. | Select when board space or reflow compatibility is prioritized over manual prototyping or vibration resistance. |
| TL074CP | Higher supply current (1.4 mA/ch), higher input noise (18 nV/√Hz), no 100 Ω drive spec; lower cost. | Suitable for non-critical audio or general-purpose gain stages where power and drive are less constrained. | Choose only if TLE2064CN's low-power, low-noise, and high-drive features are not required in the target application. |
Compared with TLE2064CD, the TLE2064CN offers identical performance in a through-hole package ideal for ruggedized industrial prototypes and field-replaceable modules; compared with TL074CP, it delivers 12× lower supply current and guaranteed 100 Ω drive - critical for precision sensor front-ends.

FAQ
What is the maximum supply voltage rating for the TLE2064CN?
The TLE2064CN has an absolute maximum supply voltage rating of ±38 V (VCC+ − VCC−), but its recommended operating range is ±3.5 V to ±18 V. Operating beyond ±18 V risks exceeding internal junction limits and invalidating parametric guarantees - always refer to Section 5.1 Absolute Maximum Ratings in the official TI datasheet for thermal derating guidance.
Does the TLE2064CN support rail-to-rail input or output operation?
The TLE2064CN does not support rail-to-rail input - its common-mode input range is –11 V to +13 V at ±15 V supply - but it delivers rail-to-rail output swing into high-impedance loads (e.g., ±13.2 V into 10 kΩ). Into 100 Ω, output swing is specified as ±12.5 V at ±15 V supply, making it suitable for driving moderate-Z loads without external buffers.
What is the typical input bias current of the TLE2064CN, and why does it matter?
The TLE2064CN exhibits ±10 pA typical input bias current at 25°C, enabled by its JFET-input stage. This ultra-low value prevents significant voltage drop across high-impedance sources (e.g., >1 MΩ sensor bridges or pH electrodes), preserving signal integrity and eliminating offset errors that would otherwise require complex calibration.
Can the TLE2064CN drive a 100 Ω load continuously without thermal shutdown?
Yes - the TLE2064CN is explicitly characterized and specified for continuous operation into 100 Ω loads at ±15 V supply, delivering ±12.5 V output swing. Its thermal design and SOA curves support this condition without derating, provided PCB copper area meets minimum heatsinking recommendations (≥1 in² per amplifier) per TI Application Report SLOA068.
How does the TLE2064CN compare to the TL074 in terms of noise and power consumption?
The TLE2064CN consumes only 120 μA per channel (480 μA total), versus 1.4 mA per channel for the TL074CP - a 12× reduction. Its input voltage noise is 43 nV/√Hz at 1 kHz, compared to 18 nV/√Hz for the TL074CP; however, the TLE2064CN's lower bias current and superior CMRR make it preferable in high-Z, noise-sensitive industrial sensor paths despite slightly higher voltage noise.
