Texas Instruments TL072CPWRG4

Overview

TL072CPWRG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V 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 high CMRR (100 dB) are critical.

For engineers reviewing the TL072CPWRG4 datasheet, TL072CPWRG4 pinout, TL072CPWRG4 application, or TL072CPWRG4 equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±1 pA typ), wide supply flexibility, output short-circuit protection, and TSSOP-8 packaging suitable for space-constrained industrial and audio PCB layouts.

Technical Context

The TL072CPWRG4 implements a dual-channel, high-slew-rate JFET-input op-amp topology with fully differential input stages and Class AB output buffers. Its internal architecture supports common-mode input voltage up to VCC+, enabling single-supply operation with proper level-shifting.

It features integrated EMI/RF filters and 2-kV HBM ESD protection, and operates across –40°C to +85°C (commercial grade). The device uses TI's legacy silicon process (C-grade), distinct from the newer H-grade variants, and exhibits typical DC offset of 3 mV and open-loop gain of 200 V/mV.

FAQ

What is the maximum supply voltage for TL072CPWRG4?

The TL072CPWRG4 supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V). Absolute maximum ratings specify 42 V for most packages, but recommended operation is capped at 40 V to ensure long-term reliability and specified performance across temperature. Exceeding this may degrade offset drift or increase quiescent current beyond datasheet limits.

Does TL072CPWRG4 have rail-to-rail input or output capability?

The TL072CPWRG4 features rail-to-rail input common-mode range - it accepts signals up to VCC+ - but does not offer rail-to-rail output swing. Its output typically swings within 115–210 mV of each rail under 10 kΩ load. For true rail-to-rail I/O, consider modern alternatives like OPA2340 or TLV2462, as TL072CPWRG4 is optimized for precision over full swing.

Is TL072CPWRG4 pin-compatible with other TL072 variants?

Yes - TL072CPWRG4 is pin-compatible with all TL072x devices in the TSSOP-8 (PW) package, including TL072IPWR and TL072HCPWR. Pin functions (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+) remain identical across C/I/H grades in this package. However, electrical performance (e.g., offset, noise, slew rate) differs by grade.

What is the typical input offset voltage of TL072CPWRG4?

The typical input offset voltage of TL072CPWRG4 is 3 mV at 25°C, with a maximum of 10 mV over the full 0°C to 70°C commercial temperature range. This value reflects its C-grade silicon; H-grade variants (e.g., TL072HCPWR) improve this to 1 mV typical. Offset drift is ±18 µV/°C, consistent across C-grade devices.

Can TL072CPWRG4 drive capacitive loads directly?

The TL072CPWRG4 is rated for stable operation with up to 300 pF capacitive load without external compensation. Beyond that, phase margin degrades and overshoot increases - especially noticeable in unity-gain follower configurations. For >300 pF loads (e.g., long cables or ADC input capacitance), use a series resistor (10–100 Ω) between output and load, or add a small isolation capacitor in the feedback path per TI application note SLOA058.
