Texas Instruments TLE2144MDWREP

Overview

TLE2144MDWREP from Texas Instruments is a radiation-hardened, quad high-speed precision operational amplifier built on the Excalibur™ complementary bipolar process. It delivers 5.9 MHz gain-bandwidth, 27 V/µs min slew rate, 10.5 nV/√Hz input noise at 1 kHz, and operates from ±2 V to ±22 V supplies across –55°C to 125°C - used in precision analog signal conditioning for aerospace data acquisition systems.

For engineers reviewing the TLE2144MDWREP datasheet, TLE2144MDWREP pinout, TLE2144MDWREP application, or TLE2144MDWREP equivalent, key selection criteria include its rail-to-rail output swing (VCC– + 0.1 V to VCC+ – 1 V), 900 µV max input offset voltage at 25°C, 10 nF capacitive load stability, and 20-mA short-circuit output current capability in harsh-environment instrumentation.

Technical Context

The TLE2144MDWREP integrates four independent op-amps with symmetrical 40-V/µs slew rate, low 10-Hz 1/f noise corner, and all-NPN output stages enabling near rail-to-rail swing under light loads. Its design achieves simultaneous low distortion and high power bandwidth for fidelity-critical signal paths.

Stable with up to 10 nF capacitive loads, it supports low-droop sample-and-hold circuits and direct buffering of long cables including 4–20 mA current loops. Input common-mode range extends to VCC– – 0.3 V without phase reversal, and CMRR/PSRR exceed 85 dB/90 dB respectively.

FAQ

What is the maximum capacitive load the TLE2144MDWREP can drive while remaining stable?

The TLE2144MDWREP is characterized for stability with capacitive loads up to 10 nF. At this loading level, bandwidth decreases to 1.8 MHz from the nominal 6 MHz, but phase margin remains sufficient for reliable operation in sample-and-hold and cable-driving applications. For loads exceeding 10 nF, external compensation or isolation resistance is required. This capability is confirmed in the TLE2144-EP datasheet SLOS577, Section 7.3.

Does the TLE2144MDWREP support single-supply operation?

Yes, the TLE2144MDWREP supports single-supply operation from 4 V to 44 V total supply range (e.g., 0 V and +36 V). Input common-mode range extends to within 0.3 V of the negative rail, and output swings to within 0.1 V of the negative rail and 1 V of the positive rail. These specifications enable true single-supply use in data acquisition front-ends without level-shifting circuitry.

What is the input offset voltage specification for the TLE2144MDWREP over temperature?

The TLE2144MDWREP has a maximum input offset voltage of 2.4 mV at 25°C and 4 mV across the full –55°C to 125°C operating range. Its typical offset voltage drift is 1.7 µV/°C, resulting in predictable, linear offset variation over temperature - a key parameter for uncalibrated high-accuracy sensor interfaces in aerospace applications.

Is the TLE2144MDWREP pin-compatible with standard industry quad op-amps?

Yes, the TLE2144MDWREP uses the industry-standard 16-pin SOIC (DW) footprint and pinout defined for quad op-amps, matching the physical layout of LM324, TL084, and OPA4340. However, electrical behavior differs significantly - notably higher slew rate, wider supply range, and enhanced temperature/radiation tolerance - so functional validation is required before drop-in replacement.

What packaging and qualification standards apply to the TLE2144MDWREP?

The TLE2144MDWREP is packaged in a 16-pin SOIC (DW) with gull-wing leads and conforms to JEDEC qualification standards for enhanced products, including Highly Accelerated Stress Test (HAST), temperature cycling, autoclave, electromigration, and bond intermetallic life testing. It is rated for operation from –55°C to 125°C and carries TI's Enhanced Product Change Notification (EPCN) and Diminishing Manufacturing Sources (DMS) support.
