Product details
Overview
TL072IDRG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in audio and precision analog systems. 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 FET-input stability and low distortion are critical.
For engineers reviewing the TL072IDRG4 datasheet, TL072IDRG4 pinout, TL072IDRG4 application, or TL072IDRG4 equivalent, key selection criteria include its dual-channel FET-input architecture, guaranteed 1 mV typical offset voltage (TL072H variant), 5.25 MHz gain-bandwidth product, output short-circuit protection, and SOIC-8 packaging with industry-standard pinout for drop-in compatibility in legacy designs.
Technical Context
The TL072IDRG4 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 common-mode input range including VCC+. Its internal EMI/RF filters and 1.5 kV HBM ESD rating support robust operation in electrically noisy environments like motor drive feedback loops and UPS control circuits.
Designed as a next-generation replacement for the original TL072, the 'H' suffix denotes improved process technology with tighter DC specifications-1 mV typical offset voltage, ±2 μV/°C drift, and 937.5 μA/ch quiescent current-while maintaining full pin and functional compatibility with legacy TL072 variants across SOIC-8, PDIP-8, and TSSOP-8 packages.

Pinout & Package
TL072IDRG4 is supplied in an 8-pin SOIC (D) package with standard industry footprint and thermal characteristics (RθJA = 147.8°C/W). The device uses a dual-amplifier topology with fully independent channels sharing only power rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 Output | Low-impedance buffered output capable of sourcing/sinking ±26 mA; requires external compensation for capacitive loads >300 pF |
| 2 | Amplifier 1 Inverting Input | FET-input node with ±1 pA typical bias current; high-impedance path sensitive to PCB leakage and guarding requirements |
| 3 | Amplifier 1 Noninverting Input | Matched to Pin 2 for CMRR optimization; common-mode range extends to VCC+ for single-supply applications |
| 4 | Negative Supply (VCC–) | Reference for both amplifiers; must be decoupled locally with ≥0.1 μF ceramic capacitor to suppress supply noise coupling |
| 5 | Amplifier 2 Noninverting Input | Electrically identical to Pin 3; enables dual-channel instrumentation or stereo signal processing without crosstalk penalty |
| 6 | Amplifier 2 Inverting Input | Matches Pin 2 in offset and bias specs; supports matched dual feedback networks in active filter topologies |
| 7 | Amplifier 2 Output | Independent output stage with same drive capability and settling behavior as Pin 1; channel separation >100 dB at DC |
| 8 | Positive Supply (VCC+) | Power rail shared by both amplifiers; recommended layout includes star grounding and separate analog/digital return paths |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Standard TL072 (non-H) variant; higher 3 mV typical offset, 10 μV/°C drift, and 1.4 mA/ch quiescent current | Lower-cost option for non-critical audio or general-purpose amplification where tighter DC specs are unnecessary | Select TL072CDR when cost sensitivity outweighs need for low offset drift and ultra-low noise in production designs |
| OPA2134PA | Higher-performance audio op-amp: 8 nV/√Hz noise, 20 V/μs slew, ±0.5 mV offset, but 2.2 mA/ch IQ and no integrated EMI filter | Targeted at premium audio gear requiring lowest possible noise floor and THD, not industrial ruggedness | Choose OPA2134PA only when system-level EMI immunity is handled externally and sub-10 nV/√Hz noise is mandatory |
Compared with TL072CDR, TL072IDRG4 offers superior DC precision and lower noise at identical price point; versus OPA2134PA, it trades marginal noise reduction for integrated EMI hardening and broader temperature qualification-making it optimal for industrial and embedded audio applications.

FAQ
What is the maximum capacitive load the TL072IDRG4 can drive stably?
The TL072IDRG4 is characterized for stable operation with up to 300 pF capacitive load without external compensation. Driving larger loads-such as long cables or ADC input capacitance-requires isolation via a series resistor (≥100 Ω) or addition of a small feedback capacitor (1–10 pF) to maintain phase margin above 56° and prevent peaking or oscillation. This limit is specified in the Electrical Characteristics table under CLOAD parameter.
Does TL072IDRG4 support single-supply operation?
Yes, TL072IDRG4 supports true single-supply operation with common-mode input range extending to VCC+, allowing the noninverting input to be biased at VCC+ for rail-to-rail input handling. However, output swing remains limited to approximately 210 mV from each rail under 10 kΩ load, so mid-rail biasing (e.g., VCC+/2) is required for AC-coupled signals to avoid clipping. This behavior is documented in the Output Voltage Swing specification.
How does the 'H' suffix in TL072IDRG4 differ from older TL072 variants?
The 'H' suffix indicates TI's next-generation die revision with improved process control: 1 mV typical input offset (vs. 3–10 mV for TL072C), ±2 μV/°C drift (vs. ±18 μV/°C), 937.5 μA/ch quiescent current (vs. 1.4 mA), and integrated EMI/RF filters. TL072IDRG4 maintains full pin, package, and functional compatibility with legacy TL072 devices while delivering tighter DC specs and enhanced noise immunity.
Is TL072IDRG4 suitable for driving ADC inputs directly?
TL072IDRG4 can drive SAR and delta-sigma ADC inputs when configured as a unity-gain buffer with proper layout: local 0.1 μF decoupling, short traces, and series resistance (≤50 Ω) to isolate capacitive kickback. Its 0.48 μs settling time to 0.01% for 2 V step ensures compatibility with 1 MSPS ADCs. However, for high-resolution (>16-bit) systems, dedicated low-output-impedance buffers like OPA350 are preferred to minimize code-dependent errors.
What thermal considerations apply to TL072IDRG4 in SOIC-8 package?
In SOIC-8 (D) package, TL072IDRG4 has a junction-to-ambient thermal resistance (RθJA) of 147.8°C/W. At maximum 2.25 mA total quiescent current (1.125 mA per amp × 2), self-heating is ~0.35°C under no load. Derating begins above 85°C ambient; full 125°C operation requires board-level thermal relief (e.g., copper pour under exposed pad if present, though D package lacks thermal pad) and airflow or reduced supply voltage to limit power dissipation.
