TLE2064MDR

Instrumentation, Op Amps, Buffer Amps Overview

The TLE2064MDR is a quad low-power JFET-input operational amplifier from the Excalibur series by Texas Instruments. It features rail-to-rail input and output capabilities, making it suitable for single-supply applications. The device operates within a supply voltage range of 3.5 V to 18 V per side (7 V to 36 V total). Key electrical characteristics include a gain-bandwidth product of 2 MHz, a slew rate of 3.4 V/µs, and an input bias current of 30 nA. It is housed in a 14-SOIC package and supports an extended industrial temperature range from -55°C to +125°C.

• High output drive capability supporting up to 45 mA per channel

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered instrumentation systems
• Active filtering in audio and signal processing circuits
• Precision data acquisition front-ends
• Industrial process control sensors

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'MDR' indicates the military-grade temperature range (-55°C to +125°C) and tape-and-reel packaging format. Confirm RoHS compliance status as datasheets may vary by revision. Ensure the ordering part number matches the required package type and thermal rating for your design constraints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both high input impedance and wide common-mode voltage range are required without sacrificing output swing. The rail-to-rail feature distinguishes it from standard JFET op-amps that lack output swing near the rails. Consider the 30 nA bias current for high-impedance source applications where FET inputs are preferred over CMOS or BJT types.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLE206x family of Excalibur operational amplifiers. The family includes dual (TLE2062), quad (TLE2064), and octal (TLE2068) variants. The 'M' designation typically denotes military/extended temperature ratings, while 'D' indicates SOIC packaging and 'R' signifies reel packaging.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Public confirmed substitutes include TLE2064IDRG4 for commercial grade SOIC versions. For pin-compatible alternatives with similar specs, consider the TLV2374 or OPA333, though input/output characteristics differ.
