Product details
Overview
TLE2064CD 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 TLE2064CD datasheet, TLE2064CD pinout, TLE2064CD application, or TLE2064CD equivalent, key selection criteria include its JFET-input architecture enabling picoampere-level bias current, rail-to-rail output swing under load, wide common-mode input range (–11 V to +13 V at ±15 V supplies), and specified performance across 0°C to 70°C ambient temperature.
Technical Context
The TLE2064CD uses JFET-input transistors with on-chip Zener trimming for offset voltage control, delivering low input bias current (±10 pA typical) and high input impedance (10¹² Ω). Its unity-gain stable architecture supports capacitive loads up to 100 pF while maintaining ≥46° phase margin.
It operates from dual supplies of ±3.5 V to ±18 V, with common-mode input range extending beyond rails and output swing within 1.5 V of each rail into 10 kΩ - and within 2.5 V into 100 Ω - enabling robust interfacing with ADC drivers and sensor front-ends in noisy environments.
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 (typical) - allows four-channel operation at <500 μA total, suitable for battery-powered analog I/O. |
| Input Bias Current | ±10 pA (25°C) - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiodes). |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supply - supports direct connection to bipolar industrial signals without level-shifting. |
| Output Drive Capability | Specified into 100 Ω - delivers >±12 V swing at ±15 V supply, enabling direct driving of transmission lines or low-Z loads. |
| Input Offset Voltage | 6 mV (max, C-suffix, full temp range) - sets DC accuracy limit in precision amplification stages. |
| Slew Rate | 2.2 V/μs (±5 V supply) - supports settling of 10-bit steps in <1 μs for medium-speed data acquisition. |
Pinout & Package
Package: PDIP-14 (Plastic Dual In-line Package), 19.3 mm × 9.4 mm footprint, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | IN– A | Inverting input of Amp A - high-impedance JFET node; bias current ≤10 pA ensures minimal loading of feedback networks. |
| 3 | IN+ A | Non-inverting input of Amp A - same high-Z characteristics as IN–; common-mode range extends to rails. |
| 4 | VCC– | Negative supply rail - must be connected to system ground or negative rail; decoupling capacitor recommended. |

| 11 | IN+ C | Non-inverting input of Amp C - supports rail-to-rail common-mode operation with no phase reversal. |
| 12 | VCC+ | Positive supply rail - accepts up to +18 V; requires local 0.1 μF ceramic decoupling to ground. |
| 13 | IN+ D | Non-inverting input of Amp D - enables simultaneous multi-channel signal conditioning without crosstalk. |
| 14 | IN– D | Inverting input of Amp D - matched offset and noise performance to other channels per datasheet characterization. |

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 max input offset voltage (4 mV vs 6 mV), same package and pinout. | Better DC accuracy required in precision sensor front-ends where offset drift dominates error budget. | Select TLE2064ACD when tighter initial offset is mandatory and cost premium is acceptable. |
| TL074CD | Higher supply current (1.4 mA/ch), lower GBW (3 MHz), no guaranteed 100 Ω drive spec. | Legacy designs prioritizing speed over power; unsuitable for low-power or high-Z sensor interfaces. | Choose TL074CD only if existing layout reuse is critical and higher power consumption is tolerable. |
Compared with TLE2064ACD, the TLE2064CD trades initial offset accuracy for broader availability and lower cost; versus TL074CD, it delivers 12× lower supply current and verified high-current output drive - making it superior for modern low-power industrial sensing.

FAQ
What is the maximum supply voltage rating for the TLE2064CD?
The TLE2064CD has an absolute maximum supply voltage rating of ±18 V (36 V total), with recommended operating range from ±3.5 V to ±18 V. Operation beyond ±18 V risks permanent damage. The device maintains specified performance across its full recommended range, including stable output swing and low distortion at ±15 V - the standard industrial rail.
Does the TLE2064CD support rail-to-rail input or output operation?
The TLE2064CD does not provide rail-to-rail input or output operation. Its common-mode input range extends to –11 V to +13 V at ±15 V supply (i.e., within ~2 V of rails), and output swing reaches ±12.5 V into 600 Ω - approximately 2.5 V from each rail. This is sufficient for most industrial signal conditioning but requires headroom planning in single-supply or near-rail applications.
What is the input bias current specification for the TLE2064CD at 25°C?
The TLE2064CD specifies input bias current of ±10 pA (typical) at 25°C, with a maximum of 2 nA across the full 0°C to 70°C operating range. This ultra-low bias current stems from its JFET-input architecture and makes the device suitable for high-impedance sources such as piezoelectric sensors, photodiodes, and electrochemical cells where leakage-induced errors must be minimized.
Can the TLE2064CD drive a 100 Ω load effectively?
Yes - the TLE2064CD is explicitly characterized for high-output-drive capability into 100 Ω loads. At ±15 V supply, it delivers ±12.5 V output swing into 600 Ω and maintains usable swing into 100 Ω, enabling direct interface with low-impedance transmission lines, relay drivers, or legacy test equipment without external buffers. Datasheet Figure 7-3 confirms stability under these conditions.
How does the TLE2064CD differ from the TLE2064M variant?
The TLE2064CD is the commercial-grade (0°C to 70°C) plastic DIP version, while the TLE2064M is the military-grade (–55°C to +125°C) variant in ceramic packages (J, FK, W). The M-suffix devices use Zener-trimmed offset and exhibit tighter long-term drift (0.04 μV/month), whereas the CD version offers cost-effective performance for non-extreme environments. Pinout and basic electrical specs align, but temperature range and reliability testing differ significantly.
