Texas Instruments TL074HIDR

Overview

TL074HIDR from Texas Instruments is a quad-channel, low-noise, JFET-input operational amplifier optimized for high-fidelity audio and precision analog signal conditioning. It delivers 20 V/μs slew rate, 1 mV typical input offset voltage, 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 and wide bandwidth are critical.

For engineers reviewing the TL074HIDR datasheet, TL074HIDR pinout, TL074HIDR application, or TL074HIDR equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±1 pA typ), high CMRR (105 dB), 5.25 MHz gain-bandwidth product, and guaranteed operation from –40°C to +125°C - all in a 14-pin SOIC package.

Technical Context

The TL074HIDR implements a fully differential JFET-input stage with cascoded gain and class-AB output stage, enabling high slew rate and low distortion. Its input stage supports common-mode voltage up to VCC+, eliminating need for level-shifting in single-supply configurations with appropriate biasing.

It features integrated EMI/RF filters and 2-kV HBM ESD protection, making it suitable for industrial environments with noisy power rails or RF-coupled interference. The device operates with quiescent current of 940 μA per amplifier and provides short-circuit output protection without latch-up.

FAQ

What is the maximum supply voltage for TL074HIDR?

The TL074HIDR supports a total supply voltage (VCC+ to VCC–) of up to 40 V, corresponding to ±20 V dual supplies or 4.5 V to 40 V single-ended operation. Absolute maximum ratings specify 42 V for most packages, but recommended operating conditions limit continuous use to 40 V to ensure long-term reliability and specified performance across temperature.

Does TL074HIDR support rail-to-rail input?

TL074HIDR supports common-mode input voltage up to VCC+, satisfying rail-to-rail input for the positive rail, but does not extend to VCC–. The minimum common-mode voltage is (VCC–) + 1.5 V, meaning it cannot accept inputs at the negative rail. This architecture enables high-side sensing without level shifters while maintaining JFET-input advantages.

Can TL074HIDR drive capacitive loads?

Yes, TL074HIDR is characterized to drive up to 300 pF capacitive load while maintaining stability, as confirmed by phase margin >56° and controlled overshoot in typical characteristics. For loads exceeding 300 pF, external series resistance (e.g., 10–100 Ω) at the output is recommended to isolate capacitance and preserve loop stability.

What is the input bias current specification for TL074HIDR at 125°C?

At TA = –40°C to +125°C, the input bias current for TL074HIDR is specified at ±5 nA maximum. This elevated value reflects JFET parameter drift at high temperature but remains orders of magnitude lower than bipolar-input op-amps, preserving accuracy in high-impedance sensor interfaces even under thermal stress.

Is TL074HIDR pin-compatible with older TL074 variants?

Yes, TL074HIDR uses the industry-standard 14-pin SOIC (D) package with identical pinout to TL074CDR, TL074ACDR, and TL074BCDR. All four amplifier channels, power pins, and input/output assignments match exactly - enabling drop-in replacement in existing designs while delivering improved offset, noise, and temperature performance.
