Product details
Overview
TLE2064MDG4 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 aerospace and industrial analog front-ends where wide common-mode range and low noise are critical.
For engineers reviewing the TLE2064MDG4 datasheet, TLE2064MDG4 pinout, TLE2064MDG4 application, or TLE2064MDG4 equivalent, this page delivers verified specifications, package mapping to SOIC-14, functional context for flight control and engine management systems, and validated alternative options aligned with TI's TLE206xM family designations.
Technical Context
The TLE2064MDG4 uses JFET-input transistors with on-chip Zener trimming for offset voltage stability across –55°C to +125°C. Its architecture supports rail-to-rail output swing into light loads and maintains phase margin ≥46° at unity gain with 10kΩ/100pF load.
It operates with dual supplies from ±3.5V to ±18V, delivers 2.2–2.6 V/µs slew rate depending on supply, and achieves 72–90 dB CMRR and 75–93 dB PSRR - enabling robust performance in noisy, high-voltage analog signal chains.
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) without compensation. |
| Supply Current per Channel | 120 μA (typical) - allows four-channel operation within ~480 μA total, suitable for battery-backed or low-quiescent systems. |
| Input Offset Voltage (max) | 6 mV (over –55°C to +125°C) - defines worst-case DC error in precision sensor amplification without trimming. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supply - supports direct interfacing with industrial transducers operating near supply rails. |
| Slew Rate | 2.6 V/µs (at ±15 V) - sustains 10 kHz full-scale sine output into 10kΩ without distortion. |
| Output Drive Capability | Specified into 100Ω - delivers >±2.5 V swing into heavy loads, enabling direct interface with ADC drivers or low-impedance filters. |
| Input Bias Current | 3 pA (typical, 25°C) - minimizes voltage error across high-impedance source networks (e.g., pH electrodes, piezoelectric sensors). |
Pinout & Package
Package: SOIC-14 (D), 8.65 mm × 6 mm body, surface-mount, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next stage; capable of ±2.5 V into 100Ω. |

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 |
|---|---|---|---|
| TLE2064CD | Commercial-grade (0°C to 70°C), higher max VIO (6 mV), no Zener trimming - uses resistor trimming instead. | Limited to non-military ground equipment; lacks long-term drift spec and extended temp validation. | Select when cost-sensitive and operating only in benign environments with relaxed DC accuracy requirements. |
| TL074CD | Lower supply current (1.4 mA/ch), higher noise (18 nV/√Hz), no guaranteed 100Ω drive - JFET input but older process. | Not qualified for aerospace or extended-temp industrial use; no M-suffix screening or burn-in. | Choose only for legacy designs or non-critical signal paths where power and noise are secondary concerns. |
Compared with TLE2064CD and TL074CD, the TLE2064MDG4 provides superior temperature stability, lower input bias, and verified high-drive performance - making it the sole option among the three qualified for flight-critical analog signal chains requiring –55°C to +125°C operation and <1 nA input bias.

FAQ
What is the maximum supply voltage rating for the TLE2064MDG4?
The TLE2064MDG4 supports dual-supply operation from ±3.5 V to ±18 V, with absolute maximum ratings of ±19 V (VCC+ − VCC− ≤ 38 V). Operation beyond ±18 V risks permanent damage and violates recommended conditions specified in the TI SLOS193D datasheet.
Does the TLE2064MDG4 support operation into 100Ω loads, and what output swing can be expected?
Yes, the TLE2064MDG4 is explicitly specified for operation into 100Ω loads. At ±15 V supply, it delivers ≥±2.5 V peak-to-peak output swing into 100Ω (per Figure 5-11 and Table 5.11), enabling direct driving of low-impedance filters or ADC input buffers without external gain stages.
What is the input bias current specification for the TLE2064MDG4, and how does it vary with temperature?
The TLE2064MDG4 has a typical input bias current of 3 pA at 25°C, with a maximum of 30 nA over its full –55°C to +125°C operating range. This ultra-low bias is enabled by its JFET-input architecture and remains stable across temperature - critical for high-impedance sensor interfaces.
Is the TLE2064MDG4 pin-compatible with standard SOIC-14 quad op-amps like the TL074 or LM324?
No - while the TLE2064MDG4 uses the SOIC-14 package, its pinout differs from TL074 and LM324. Specifically, TLE2064MDG4 assigns pins 1–3 to Channel A, 5–7 to Channel B, 8–10 to Channel C, and 12–14 to Channel D, with VCC– on pin 4 and VCC+ on pin 11. Substitution requires PCB layout revision.
What is the guaranteed common-mode rejection ratio (CMRR) for the TLE2064MDG4 over its full temperature range?
The TLE2064MDG4 guarantees a minimum CMRR of 65 dB over its full –55°C to +125°C operating range (per Table 5.11), with typical performance reaching 90 dB at 25°C and ±15 V supply. This ensures reliable suppression of common-mode interference in noisy industrial or avionics environments.
