Texas Instruments TL074CPWRE4

Overview

TL074CPWRE4 from Texas Instruments is a quad JFET-input operational amplifier optimized for low-noise, high-slew-rate analog signal conditioning in audio and precision instrumentation. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V dual-supply operation, and rail-to-rail common-mode input range extending to VCC+. It is widely used in pro-audio mixers and battery test equipment where low distortion (0.003% THD+N) and stable DC performance are critical.

For engineers reviewing the TL074CPWRE4 datasheet, TL074CPWRE4 pinout, TL074CPWRE4 application, or TL074CPWRE4 equivalent, key selection criteria include its FET-input architecture enabling pA-level bias current, wide supply flexibility, integrated EMI/RF filtering, and guaranteed operation from –40°C to +85°C - all in a 14-pin TSSOP package with industry-standard pinout.

Technical Context

The TL074CPWRE4 belongs to the TL074x family of quad op-amps featuring JFET differential input stages with high input impedance (>1 TΩ), low input capacitance (6 pF common-mode), and internal compensation for unity-gain stability. Its architecture supports wide common-mode input range (including VCC+) and provides output short-circuit protection without latch-up.

It operates across ±2.25 V to ±20 V supplies, delivering 125 dB open-loop gain and 5.25 MHz gain-bandwidth product. The device uses TI's legacy silicon process (C-grade), distinct from the newer H-grade (TL074H), resulting in higher offset voltage (3–10 mV typ) and lower ESD rating (2 kV HBM) compared to H-variants.

Key Specifications

Pinout & Package

The TL074CPWRE4 is housed in a 14-pin TSSOP (PW) package, 5.0 mm × 4.4 mm, 0.65 mm pitch, with exposed thermal pad (non-electrical). This RoHS-compliant, surface-mount package supports automated assembly and offers improved thermal resistance (R_θJA = 200.3°C/W) versus PDIP.

FAQ

What is the maximum supply voltage for TL074CPWRE4?

The TL074CPWRE4 supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V), with absolute maximum ratings specifying 42 V across VCC+ and VCC–. Operation beyond ±20 V is not recommended, as electrical characteristics are only guaranteed within the recommended operating conditions of ±2.25 V to ±20 V.

Does TL074CPWRE4 have rail-to-rail input or output capability?

The TL074CPWRE4 features rail-to-rail common-mode input range - it accepts signals up to and including VCC+ - but does not provide rail-to-rail output swing. Its typical output voltage swing is ±12 V into 10 kΩ with ±15 V supplies, with headroom of ~105–215 mV from each rail depending on load.

Is TL074CPWRE4 pin-compatible with other TL074 variants?

Yes, TL074CPWRE4 is pin-compatible with all TL074x devices in the 14-pin TSSOP (PW) package, including TL074IPWR and TL074H series. Pin functions match Table 4-6 in the datasheet, and no PCB changes are required when substituting within the same PW package variant.

What is the input offset voltage specification for TL074CPWRE4?

The TL074CPWRE4 (C-grade) has a typical input offset voltage of 3 mV, with a maximum of 10 mV at 25°C and up to 13 mV across the full operating temperature range (–40°C to +85°C), as specified in Section 5.8 of the datasheet.

Can TL074CPWRE4 drive capacitive loads directly?

The TL074CPWRE4 is characterized to drive up to 300 pF capacitive load without instability, per its electrical specifications. For loads exceeding 300 pF, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain phase margin and prevent peaking or oscillation.
