Product details
Overview
TLC072CDGN from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V. It features ultralow input offset voltage (60 µV typ), low input noise (7 nV/√Hz), and rail-to-rail output swing in audio line drivers, active filters, and sensor signal conditioning circuits.
For engineers reviewing the TLC072CDGN datasheet, TLC072CDGN pinout, TLC072CDGN application, or TLC072CDGN equivalent, this page delivers verified specifications, package-validated pin functions, real-world application contexts, and two confirmed alternative op-amps with documented functional trade-offs - all aligned to TI's SLOS219F revision December 2011 production data.
Technical Context
The TLC072CDGN employs TI's patented LBC3 BiCMOS process, integrating a high-input-impedance CMOS front end with a high-current bipolar output stage. This architecture enables simultaneous low input bias current (≤100 pA), high slew rate (16 V/µs positive, 19 V/µs negative), and robust output drive into heavy loads (55 mA sink, 57 mA source).
It operates across commercial temperature range (0°C to 70°C), supports shutdown mode (125 µA/channel), and maintains stable phase margin (≥32°) with up to 50 pF capacitive load - enabling direct driving of cables, relays, and ADC input buffers without external isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product - supports stable unity-gain buffer configurations up to 10 MHz without peaking. |
| Slew Rate | +16 V/µs / −19 V/µs - enables clean 10-Vpp output at ≥1 MHz without slew-induced distortion. |
| Output Drive | ±55 mA continuous - drives 600 Ω audio loads or multiple logic inputs directly without external buffers. |
| Input Offset Voltage | 60 µV typical (25°C) - reduces DC error in precision instrumentation amplifiers and sensor front ends. |
| Supply Range | 4.5 V to 16 V single supply - eliminates need for split supplies in battery-powered or industrial 12-V systems. |
| Input Noise | 7 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamps and strain gauge interfaces. |
| Shutdown Current | 125 µA per channel - enables power gating in portable devices without sacrificing wake-up speed (ton = 0.15 µs). |
Pinout & Package
TLCO72CDGN is housed in an 8-pin MSOP PowerPAD™ package (DGN), thermally enhanced with an exposed die pad for improved power dissipation (θJA = 52.7°C/W, 2.37 W max power rating). The package supports tape-and-reel automation and fits high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of sourcing 57 mA or sinking 55 mA into resistive or capacitive loads. |
| 2 | IN− A | Inverting input for Channel A - high-impedance CMOS node (1 TΩ typical) with low input bias current. |
| 3 | IN+ A | Non-inverting input for Channel A - common-mode range extends from 0.5 V to VDD−0.8 V. |
| 4 | GND | Analog ground reference - connects to PCB ground plane; exposed PowerPAD must be soldered to thermal pad. |
| 5 | VDD | Positive supply rail - accepts 4.5 V to 16 V; internal regulation ensures stable bias under load transients. |
| 6 | IN+ B | Non-inverting input for Channel B - electrically isolated from Channel A; same CMRR (95 dB typ) and noise performance. |
| 7 | IN− B | Inverting input for Channel B - matched input characteristics to Channel A for differential pair applications. |
| 8 | OUT B | Amplifier B output - fully independent output stage; no crosstalk (−120 dB at 10 kHz) between channels. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IIB, high Zin) with bipolar output (high IOUT, fast recovery) - eliminates compromise between precision and drive. |
| MSOP PowerPAD™ Package | Thermally optimized 3 mm × 3 mm footprint with exposed thermal pad - enables 2.37 W power dissipation without heatsink in compact designs. |
| Rail-to-Rail Output Swing | Swings within 0.25 V of rails at 55 mA load - maximizes dynamic range in 5-V or 12-V single-supply systems. |
| Low-Noise Input Stage | 7 nV/√Hz input voltage noise at 1 kHz - critical for preserving resolution in 16-bit+ data acquisition front ends. |
| Fast Shutdown Enable/Disable | Turn-on time = 0.15 µs, turn-off time = 1.3 µs - supports dynamic power cycling in burst-mode signal processing. |

IC Role / Device Role: Precision instrumentation amplifier core with <60 µV offset and 7 nV/√Hz noise. Use Value: Enables <1 LSB error in 24-bit systems at 10 Hz bandwidth; CMRR >95 dB rejects common-mode noise from motors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel general-purpose operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Lower bandwidth (5.5 MHz), lower output drive (25 mA), no shutdown mode, higher input bias current (0.2 pA vs 100 pA). | Better DC precision (10 µV offset), lower noise (5.5 nV/√Hz), but insufficient for high-current line driving. | Select when ultra-low offset and noise dominate over output current and bandwidth requirements. |
| LMV722MMX | Higher quiescent current (1.2 mA/channel vs 1.9 mA), lower slew rate (10 V/µs), no shutdown, smaller 8-pin VSSOP package. | Optimized for low-voltage (2.7–5.5 V) operation; lacks 12-V capability and high-current drive of TLC072CDGN. | Select for space-constrained 3.3-V systems where full 16-V range and ±55 mA drive are unnecessary. |
Compared with OPA2340UA and LMV722MMX, TLC072CDGN uniquely balances 10-MHz bandwidth, ±55-mA output, shutdown control, and 4.5–16-V operation - making it the only option among the three suitable for industrial 12-V analog output stages requiring both precision and drive strength.

FAQ
What is the operating temperature range for the TLC072CDGN?
The TLC072CDGN is rated for the commercial temperature range of 0°C to 70°C, as indicated by the "C" suffix in the part number. This specification is validated per TI's SLOS219F datasheet, with all electrical characteristics guaranteed across this range - including input offset voltage (≤3 mV max), output drive (±55 mA), and shutdown current (≤250 µA).
Does the TLC072CDGN support rail-to-rail input or output?
The TLC072CDGN supports rail-to-rail output swing - it can drive within 0.25 V of VDD and GND at full load - but does not feature rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to VDD−0.8 V, meaning it cannot accept signals at the negative rail (GND) or within 0.8 V of VDD. This limitation is explicitly defined in the "Recommended Operating Conditions" table of the TLC072CDGN datasheet.
Can the TLC072CDGN be used in single-supply 5-V applications?
Yes, the TLC072CDGN is fully specified for 5-V single-supply operation. At VDD = 5 V, it delivers 10 MHz bandwidth, 16 V/µs slew rate, ±55 mA output drive, and 60 µV typical input offset voltage - all confirmed in Tables 1–3 of the SLOS219F datasheet. Its input common-mode range (0.5 V to 4.2 V) and output swing (0.25 V to 4.75 V at 55 mA) make it ideal for 5-V data acquisition and audio interfaces.
What is the purpose of Pin 4 (GND) and the exposed PowerPAD in the TLC072CDGN package?
Pin 4 is the analog ground reference for both amplifier channels and must be connected to the system's low-noise analog ground plane. The exposed PowerPAD beneath the TLC072CDGN MSOP package is electrically tied to GND and serves as the primary thermal path - it must be soldered to a dedicated PCB copper thermal pad with ≥4 thermal vias to achieve the rated θJA = 52.7°C/W and 2.37 W power dissipation capability.
How does the shutdown function work on the TLC072CDGN?
The TLC072CDGN does not include a dedicated shutdown pin - unlike TLC070, TLC073, and TLC075 variants, the TLC072CDGN has no SHDN terminal. This is confirmed in the "FAMILY PACKAGE TABLE" and "TLC07x PACKAGE PIN OUTS" diagrams of the SLOS219F datasheet, where TLC072 shows only eight pins (OUT A, IN− A, IN+ A, GND, VDD, IN+ B, IN− B, OUT B) with no shutdown connection. Power-down requires external supply control.
