TL074IDE4

Instrumentation, Op Amps, Buffer Amps Overview

The TL074IDE4 is a quad low-noise JFET-input general-purpose operational amplifier manufactured by Texas Instruments. It features four independent amplifiers within a single 14-pin SOIC package. Key electrical parameters include a gain-bandwidth product of 3 MHz, a slew rate of 13 V/µs, and an input bias current of 2 nA. The device operates with supply voltages ranging from 5 V to 36 V total or ±2.5 V to ±18 V dual supplies. Input offset voltage is typically 8 mV, and the input noise density is 18 nV/√Hz at 1 kHz.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E4' indicates lead-free packaging compliance per manufacturer standards. Confirm the package type matches the required PCB footprint, as the 'I' designator specifies a plastic small-outline package. Ensure the operating temperature range aligns with system thermal constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high input impedance and low noise are prioritized over rail-to-rail output swing. Compare against bipolar input op-amps if lower offset voltage is critical, noting that JFET inputs offer superior bias current performance. Verify that the 13 V/µs slew rate meets the bandwidth requirements of the target application signals.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TL074 family of quad operational amplifiers. It shares architectural similarities with the TL071 (single) and TL072 (dual) variants. The 'E4' suffix typically denotes environmental compliance, specifically lead-free manufacturing processes, distinguishing it from older non-compliant versions within the same functional series.
