Texas Instruments TL072CPSR

Overview

TL072CPSR from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in audio and precision analog circuits. 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 fidelity and DC stability are critical.

For engineers reviewing the TL072CPSR datasheet, TL072CPSR pinout, TL072CPSR application, or TL072CPSR equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±120 pA typ), offset voltage drift of ±2 μV/°C, output short-circuit protection, and compatibility with single- or dual-supply configurations up to ±20 V.

Technical Context

The TL072CPSR implements a two-stage JFET differential input stage followed by a Class-A gain stage and push-pull output stage, enabling high open-loop gain (125 dB typ) and wide GBW (5.25 MHz). Its input stage supports common-mode voltage up to VCC+, eliminating need for level-shifting in high-side sensing.

It features integrated EMI/RF filters and 2-kV HBM ESD rating, supporting robust operation in electrically noisy environments such as motor drive feedback loops and UPS control stages without external filtering.

Key Specifications

Pinout & Package

The TL072CPSR is housed in an 8-pin SO (Small Outline) package (PS), measuring 4.9 mm × 3.9 mm × 1.75 mm, with gull-wing leads and standard JEDEC MS-012AC footprint.

FAQ

What is the maximum operating temperature range for the TL072CPSR?

The TL072CPSR is rated for operation from 0°C to +70°C ambient temperature, as specified in the "TL07xC" device grade. This commercial-grade temperature range is confirmed in Section 5.8 of the official TI datasheet (SLOS080W), and applies specifically to the C-suffix variant including TL072CPSR. It is not rated for extended industrial or military temperature ranges.

Does the TL072CPSR support single-supply operation?

Yes, the TL072CPSR supports true single-supply operation from 4.5 V to 40 V. Its common-mode input voltage range extends to VCC+, allowing input signals referenced to the positive rail. Output swing is rail-limited (e.g., ~210 mV from VCC+ with 10 kΩ load), so proper headroom must be allocated in single-supply designs using TL072CPSR.

What is the typical input offset voltage for TL072CPSR?

The typical input offset voltage for TL072CPSR is 3 mV at 25°C, with a maximum of 10 mV over the full 0°C to +70°C operating range. This value is documented in Section 5.8 (Electrical Characteristics for TL07xC) of the TI datasheet and reflects the "C" grade performance, distinct from tighter-spec "H" or "M" variants.

Can TL072CPSR drive capacitive loads directly?

The TL072CPSR is characterized to drive up to 300 pF capacitive load stably without external compensation, as specified in the "CLOAD" parameter (Section 5.7). For loads exceeding 300 pF, series output resistance (e.g., 10–100 Ω) is recommended to maintain phase margin and prevent peaking or oscillation in circuits using TL072CPSR.

Is TL072CPSR pin-compatible with other TL072 variants in SO-8 package?

Yes, TL072CPSR is pin-compatible with all TL072x devices in the PS (SO-8) package, including TL072IP (PDIP-8), TL072CDR (SOIC-8), and TL072HPSR (SO-8, H-grade). Pin functions (1OUT, 2IN–, 3IN+, 4VCC–, 5IN+, 6IN–, 7OUT, 8VCC+) are identical across all TL072 variants in the same package type, ensuring drop-in replacement within the same footprint when using TL072CPSR.
