Texas Instruments TL072ACPSRG4

Overview

TL072ACPSRG4 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 high fidelity and DC accuracy are critical.

For engineers reviewing the TL072ACPSRG4 datasheet, TL072ACPSRG4 pinout, TL072ACPSRG4 application, or TL072ACPSRG4 equivalent, key selection factors include its FET-input architecture for ultra-low bias current (±1 pA typ), low offset drift (±2 μV/°C), output short-circuit protection, and compatibility with single- or dual-supply configurations across –40°C to +85°C.

Technical Context

The TL072ACPSRG4 employs a JFET differential input stage followed by a high-gain Darlington composite output stage, enabling wide common-mode input range including VCC+ and low input bias current. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.

It operates over ±2.25 V to ±20 V supplies (4.5 V to 40 V total), supports rail-sensing inputs, and features integrated EMI/RF filters and 2 kV HBM ESD protection. The device exhibits 5.25 MHz gain-bandwidth product and 0.48 μs settling time to 0.01% for 2 V step under G = +1.

FAQ

What is the operating temperature range for TL072ACPSRG4?

The TL072ACPSRG4 is rated for operation from –40°C to +85°C, meeting industrial temperature requirements. This range is confirmed in Section 5.3 of the official datasheet under "Recommended Operating Conditions" for TL07xAC devices. Its performance specifications-including offset drift (±2 μV/°C) and quiescent current-are guaranteed across this full span, making TL072ACPSRG4 suitable for outdoor solar monitoring and factory-floor test equipment.

Does TL072ACPSRG4 support single-supply operation?

Yes, TL072ACPSRG4 supports true single-supply operation from 4.5 V to 40 V total supply (e.g., 0 V and +12 V). Its common-mode input range extends to VCC+, allowing input signals referenced to ground or near the positive rail. However, output swing is limited to within ~210 mV of each rail under 10 kΩ load, so proper headroom must be maintained for full-scale signal fidelity in TL072ACPSRG4 designs.

What is the maximum capacitive load TL072ACPSRG4 can drive stably?

TL072ACPSRG4 is specified to drive up to 300 pF capacitively without oscillation, per Section 5.7 "Electrical Characteristics for TL07xH". This capability is enabled by internal compensation and verified under G = +1, RL = 10 kΩ, and CL = 300 pF test conditions. For larger loads, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to maintain phase margin above 56° in TL072ACPSRG4 applications.

How does TL072ACPSRG4 differ from TL072H variants?

TL072ACPSRG4 uses the older "C"-grade die (not the newer "H"-suffix process), evidenced by its 10 mV max offset voltage (vs. 4 mV for TL072H), absence of 1.5 kV HBM ESD rating (TL072H specifies 2 kV), and lack of integrated EMI/RF filters. Its PS package (SO) and "A" grade denote improved initial offset (3 mV typ) and tighter AC specs versus standard TL072C, but it retains the legacy thermal and noise characteristics documented in Section 5.8 of the datasheet for TL07xAC devices.

Is TL072ACPSRG4 pin-compatible with other TL072 variants in SO-8 packages?

Yes, TL072ACPSRG4 is fully pin-compatible with all TL072x devices in SO-8 (D, PS, NS) packages, including TL072CDR, TL072IDR, and TL072HPSR. Pin functions-1OUT, 1IN–, 1IN+, VCC–, VCC+, 2IN–, 2OUT, 2IN+-are identical across these variants per Table 4-3 of the datasheet. No PCB layout changes are required when substituting TL072ACPSRG4 into existing TL072 SO-8 footprints, though electrical performance differences must be validated per application.
