Product details
Overview
TLE2064AIDR from Texas Instruments is a quad FET-input operational amplifier with 1.1 MHz gain-bandwidth product, 120 µA per channel supply current, ±18 V maximum supply voltage, and high-output-drive capability into 100 Ω loads. It serves as a precision, low-power signal conditioning amplifier in analog input modules for industrial control systems.
For engineers reviewing the TLE2064AIDR datasheet, TLE2064AIDR pinout, TLE2064AIDR application, or TLE2064AIDR equivalent, key selection criteria include its JFET-input architecture enabling picoampere-level input bias current, wide common-mode range (–11 V to +13 V at ±15 V supplies), and specified performance over –40°C to +85°C industrial temperature range.
Technical Context
The TLE2064AIDR implements a JFET-input differential pair with on-chip Zener trimming for offset voltage calibration, delivering low input bias current (±10 pA typ) and high input impedance (≥10¹² Ω). Its unity-gain-stable architecture supports rail-to-rail output swing into 10 kΩ loads and maintains 46° phase margin with 100 pF capacitive load.
It operates across ±3.5 V to ±18 V dual supplies and achieves 2.6 V/µs slew rate at ±15 V, enabling accurate amplification of medium-bandwidth sensor signals while maintaining DC precision-input offset voltage is 2.6 mV max at 25°C and 3.9 mV over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain (e.g., AV = 10). |
| Supply Current per Channel | 120 µA (typ) - supports ultra-low-power multi-channel analog front-ends without thermal derating. |
| Input Offset Voltage | 2.6 mV max at 25°C - ensures <±5 mV total error in 12-bit ADC interface applications with ±10 V input range. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supply - accommodates bipolar sensor outputs directly without level-shifting. |
| Slew Rate | 2.6 V/µs at ±15 V - supports faithful reproduction of 10 kHz sine waves with ≤1% distortion at 10 VPP output. |
| Output Drive | Specified into 100 Ω - delivers ≥±2.5 V swing into heavy loads, suitable for driving coaxial cables or multiplexed ADC inputs. |
| Input Bias Current | ±10 pA (typ) - minimizes voltage error across high-impedance sources (e.g., piezoelectric sensors, pH electrodes). |

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 | Higher input offset voltage (4 mV max vs. 2.6 mV), commercial temperature range (0°C to 70°C). | Limited to non-industrial environments; unsuitable for extended temperature deployments. | Select when cost sensitivity outweighs precision and temperature robustness requirements. |
| TL074CDR | Lower GBW (3 MHz), higher supply current (1.4 mA/ch), no Zener-trimmed offset (10 mV max). | Higher power consumption and reduced DC accuracy limit use in battery-powered or precision systems. | Choose only for legacy designs where pin compatibility is mandatory and performance margins are sufficient. |
Compared with TLE2064CDR and TL074CDR, the TLE2064AIDR provides superior DC precision, lower power, and guaranteed industrial temperature operation-making it the optimal choice for new designs requiring long-term stability and sensor-grade accuracy.

FAQ
What is the maximum supply voltage rating for the TLE2064AIDR?
The TLE2064AIDR has an absolute maximum supply voltage rating of ±18 V (36 V total), with recommended operating range from ±3.5 V to ±18 V. Exceeding ±18 V risks permanent damage, and operation below ±3.5 V may impair output swing and slew rate performance. The TLE2064AIDR must be operated within these limits to ensure reliable function and longevity.
Does the TLE2064AIDR support single-supply operation?
Yes, the TLE2064AIDR supports single-supply operation with appropriate input/output 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 can swing within ~1.5 V of each rail. For true rail-to-rail input/output, external level-shifting or a dedicated RRIO op-amp is required. The TLE2064AIDR remains functional but not optimized for true single-supply zero-input applications.
What is the input offset voltage specification for the TLE2064AIDR over temperature?
The TLE2064AIDR specifies a maximum input offset voltage of 2.6 mV at 25°C and 3.9 mV over the full –40°C to +85°C operating range. This is achieved via on-chip Zener trimming, and the temperature coefficient is tightly controlled at 1 µV/°C. These values are verified per TI's SLOS193D datasheet and apply specifically to the "A" grade variant in SOIC-14 packaging.
Can the TLE2064AIDR drive a 100 Ω load effectively?
Yes-the TLE2064AIDR is explicitly characterized into 100 Ω loads per its datasheet, delivering ≥±2.5 V output swing at ±15 V supply. This high-output-drive capability eliminates the need for external buffers in applications such as driving coaxial cables, multiplexed ADC inputs, or low-impedance filters. Performance is validated across temperature and supply variations, confirming robustness in demanding signal chain roles.
Is the TLE2064AIDR pin-compatible with other TLE2064 variants?
Yes-the TLE2064AIDR (SOIC-14) shares identical pinout with TLE2064CDR, TLE2064IDR, and TLE2064MDR. All variants use the same D-package footprint and terminal assignment. However, electrical specifications differ: the "A" grade offers tighter offset voltage (2.6 mV vs. 4 mV), "I" grade extends temperature range to –40°C to +85°C, and "M" grade adds military-grade screening. Pin compatibility enables drop-in replacement where performance and qualification requirements align.
