TLE2074ACNE4

Instrumentation, Op Amps, Buffer Amps Overview

The TLE2074ACNE4 is a quad low-noise high-speed operational amplifier from the Excalibur family, manufactured by Texas Instruments. It features a 10 MHz gain-bandwidth product and a 40 V/µs slew rate. The device operates on supply voltages ranging from ±2.25 V to ±19 V. Key electrical characteristics include a maximum input offset voltage of 3 mV, an input bias current of 175 pA, and an input voltage noise density of 12 nV/√Hz at 1 kHz. It utilizes JFET-input transistors with on-chip Zener trimming for offset voltage adjustment.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'N' corresponds to the Plastic Dual In-Line Package (PDIP) with 14 pins as documented in the official datasheet. Confirm the 'C' suffix indicates the commercial temperature range of 0°C to 70°C. Ensure the component matches the TLE2074A variant specifications regarding offset voltage limits before integration into the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-speed performance combined with low noise is required for multi-channel applications. The quad configuration reduces board space compared to single or dual amplifiers. Consider the PDIP package for prototyping or through-hole designs where surface mount options are not feasible. Verify that the ±19 V maximum supply rating aligns with the system power architecture.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TLE207x and TLE207xA Excalibur series, designed for high-voltage and high-precision applications. The family includes single (TLE2071), dual (TLE2072), and quad (TLE2074) variants. The TLE2074ACNE4 specifically integrates four independent amplifiers in one package, sharing common power and ground connections while maintaining individual signal paths for each channel.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same package include other TLE2074 variants such as TLE2074AIN or TLE2074CDW, provided the temperature range and package type match the design requirements. Cross-family replacements require careful evaluation of electrical parameters like slew rate and noise density.
