Product details
Overview
TLE2064MDRG4 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 at ±15V supplies, and JFET-input architecture enabling ultra-low input bias current (±3pA typical). It serves as a precision, low-power signal conditioning amplifier in high-reliability analog front-ends for aerospace and industrial control systems.
For engineers reviewing the TLE2064MDRG4 datasheet, TLE2064MDRG4 pinout, TLE2064MDRG4 application, or TLE2064MDRG4 equivalent, key selection criteria include its −55°C to +125°C operating range, SOIC-14 package, guaranteed 2mV max input offset voltage at 25°C (M-grade), high output drive into 100Ω loads, and FET-input noise performance optimized for low-frequency sensor interfaces.
Technical Context
The TLE2064MDRG4 implements a JFET-input differential pair with on-chip Zener trimming for DC precision, delivering stable AC performance across its full military temperature range. Its architecture supports rail-to-rail input common-mode range (−11V to +13V at ±15V supplies) and maintains ≥46° phase margin with 100pF capacitive load.
It operates from dual supplies of ±3.5V to ±18V, features 6TΩ common-mode input impedance and 540GΩ differential input impedance, and achieves 2.6V/µs slew rate at ±15V - enabling accurate amplification of moderate-bandwidth sensor signals without distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1MHz - sets usable closed-loop bandwidth for unity-gain stable configurations up to ~1MHz. |
| Supply Current per Channel | 120μA (typical) - enables battery-powered or energy-constrained systems with four independent op-amps. |
| Input Offset Voltage (max) | 2mV at 25°C (M-grade) - ensures ≤2mV initial error in precision DC-coupled gain stages. |
| Output Swing (±15V) | ±14.9V into 10kΩ - delivers near-rail output dynamic range for maximum signal fidelity. |
| Input Bias Current | ±3pA (typical) - minimizes voltage error across high-impedance sources like piezoelectric sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Wider bandwidth (3MHz), higher supply current (1.4mA/ch), commercial temp range (0°C to 70°C), no Zener trimming (max VIO = 10mV). | Not qualified for extended temperature or high-reliability aerospace use; suitable for cost-sensitive industrial or audio designs. | Select TL074CDR only when bandwidth >1.1MHz is required and military-grade specs are unnecessary. |
| OPA4134UA | Lower noise (8nV/√Hz), lower VIO (0.5mV max), but limited to −40°C to +85°C and higher supply current (4mA/ch). | Preferred for high-fidelity audio or lab instrumentation where noise dominates; not rated for −55°C operation. | Choose OPA4134UA when ultra-low noise and offset outweigh temperature range and power constraints. |
Compared with TL074CDR and OPA4134UA, the TLE2064MDRG4 uniquely balances military-temperature operation, ultra-low power (120μA/ch), and FET-input precision - making it irreplaceable in space-constrained, battery-backed, or high-reliability embedded control systems where all three attributes are mandatory.

FAQ
What is the maximum operating temperature range for the TLE2064MDRG4?
The TLE2064MDRG4 is rated for operation from −55°C to +125°C, meeting military-grade temperature specifications. This range is validated per the M-suffix designation in the TI datasheet SLOS193D and applies to all electrical parameters unless otherwise noted. The SOIC-14 package supports this full range with appropriate PCB layout and thermal management.
Does the TLE2064MDRG4 support single-supply operation?
Yes, the TLE2064MDRG4 supports single-supply operation with a minimum total supply voltage of 7V (e.g., VCC+ = +7V, VCC– = 0V). Its input common-mode range extends to within 1.6V of the negative rail and its output can swing to within 1.1V of either rail under light load - enabling use in 5V or 12V single-rail systems when biased appropriately.
What is the input offset voltage specification for the TLE2064MDRG4 at 25°C?
The TLE2064MDRG4 has a maximum input offset voltage of 2mV at 25°C, as specified for the M-grade variant in Table 4-3 and confirmed in Section 5.11 of the TI datasheet SLOS193D. This value is guaranteed and tested; typical performance is 0.1mV, and long-term drift is 0.04μV/month at 25°C.
Can the TLE2064MDRG4 drive a 100Ω load effectively?
Yes, the TLE2064MDRG4 is explicitly characterized for high-output-drive capability into 100Ω loads. At ±15V supplies, it delivers ±12.5V minimum output swing into 600Ω and maintains robust performance into 100Ω - a key differentiator versus standard low-power op-amps. This is verified in Sections 5.5 and 5.13 of the datasheet.
Is the TLE2064MDRG4 pin-compatible with other TLE2064 variants?
Yes, the TLE2064MDRG4 (SOIC-14, D package) shares identical pinout with all other TLE2064x variants in the D package, including TLE2064CDR, TLE2064IDR, and TLE2064AMDR. Pin compatibility is confirmed in Figure 4-4 of the datasheet and applies across all temperature grades and offset grades when using the same SOIC-14 footprint.
