Texas Instruments TLE2064AID

Overview

TLE2064AID from Texas Instruments is a quad FET-input operational amplifier with 1.1MHz gain-bandwidth product, ±3.5V to ±18V supply range, and 120μA per channel supply current. It delivers high-output drive into 100Ω loads and features low input bias current (±10pA typical), making it suitable for precision analog input modules in industrial control systems.

For engineers reviewing the TLE2064AID datasheet, TLE2064AID pinout, TLE2064AID application, or TLE2064AID equivalent, key selection criteria include its JFET-input architecture, 4mV max input offset voltage at –40°C to 85°C, SOIC-14 package, and specified performance into low-impedance loads - critical for sensor signal conditioning and engine control interface circuits.

Technical Context

The TLE2064AID uses JFET-input transistors with on-chip Zener trimming for DC precision, supporting rail-to-rail output swing capability (±13V at ±15V supply) and maintaining stability with capacitive loads up to 100pF. Its 2.2V/µs slew rate and 140kHz full-power bandwidth enable accurate amplification of medium-speed sensor signals.

Designed for operation across –40°C to 85°C, the device achieves 72dB common-mode rejection and 75dB supply-voltage rejection at ±15V, ensuring robustness against noise coupling in mixed-signal environments such as flight control units and digital engine management systems.

FAQ

What is the maximum input offset voltage specification for TLE2064AID over its full operating temperature range?

The TLE2064AID has a maximum input offset voltage of 4mV across its full operating temperature range of –40°C to 85°C. This value is confirmed in Table 4-3 of the datasheet for the "I suffix" grade and applies specifically to the TLE2064AID variant in SOIC-14 packaging. The 4mV limit ensures predictable DC error in precision sensor interfaces without requiring calibration or trimming circuits in the final design. TLE2064AID maintains this specification under all recommended supply voltages and load conditions.

Does TLE2064AID support operation into 100Ω loads, and what is the evidence?

Yes, TLE2064AID is explicitly specified for operation into 100Ω loads, as stated in the "Features" section of the datasheet: "High output drive, specified into 100Ω loads." This is further validated by output swing data in Section 5.5 (e.g., ±12.5V min swing into 600Ω at ±15V supply), and by the "Operating Characteristics" table showing stable slew rate and settling time under loaded conditions. The SOIC-14 package's thermal design supports sustained dissipation during 100Ω drive, distinguishing TLE2064AID from general-purpose op-amps lacking this guarantee. TLE2064AID meets this requirement across its full temperature range.

What is the supply current consumption of TLE2064AID per channel, and how does it vary with supply voltage?

TLE2064AID consumes 120μA per channel typical at ±5V supply and 125μA per channel typical at ±15V supply, with a maximum of 350μA per channel across –40°C to 85°C. These values are documented in Sections 5.3 and 5.9 of the datasheet under "ICC Supply current." The minimal increase (5μA) from ±5V to ±15V reflects efficient JFET-input biasing and confirms low power sensitivity to rail voltage - a key advantage for TLE2064AID in multi-rail industrial systems where supply headroom varies. Total quiescent draw for all four channels remains under 1.4mA.

Is TLE2064AID pin-compatible with other members of the TLE2064 family, and which packages share identical pinouts?

Yes, TLE2064AID is pin-compatible with all TLE2064x variants in the SOIC-14 (D) package, including TLE2064ID, TLE2064CD, and TLE2064BD. Pinout identity is confirmed in Figure 4-4 ("TLE2064, TLE2064A, and TLE2064B D, J, N, or W Package") and Table 4-3, which lists TLE2064AID under the "SMALL OUTLINE (D)" column. However, TLE2064AID is not pin-compatible with PDIP-14 (N), CDIP-14 (J), or LCCC-20 (FK) variants due to differing pin counts and layouts. TLE2064AID retains identical pin functions and spacing as other SOIC-14 versions, enabling drop-in replacement within that package group.

What is the common-mode input voltage range for TLE2064AID at ±15V supply, and why does it matter for sensor interfacing?

At ±15V supply, TLE2064AID has a common-mode input voltage range of –11V to +13V, as specified in Section 5.2 ("Recommended Operating Conditions"). This asymmetric range - extending closer to the positive rail than the negative - enables direct connection of sensors whose outputs swing near ground or negative reference points, such as bridge-based pressure transducers or bipolar current-sense amplifiers. The –11V lower bound ensures compatibility with signals referenced to –5V or –12V rails, while the +13V upper limit supports 0–10V industrial standards. This range is a verified specification for TLE2064AID and directly impacts usable input dynamic range in real-world sensor circuits.
